BCBA Exam — Questions and Answers

Question 1: A behavior analyst recommends high-probability request sequences before asking a learner to complete a low-probability task. This is an example of:

Extinction
Shaping
Differential reinforcement of incompatible behavior
Behavior momentum (Correct answer)

Correct answer: Behavior momentum

Behavioral momentum uses a series of high-p requests reinforced before the low-p request to build compliance momentum and reduce problem behavior associated with transitions.

Question 2: Which of the following is a primary ethical concern associated with the use of a reversal (A-B-A-B) design?

It is not effective for demonstrating experimental control.
The withdrawal of an effective intervention may be harmful to the client. [7, 8] (Correct answer)
It cannot be used to evaluate more than one treatment.
It requires a significant amount of time to demonstrate a functional relation.

Correct answer: The withdrawal of an effective intervention may be harmful to the client. [7, 8]

The primary ethical concern with a reversal design is the temporary removal of an intervention that has proven to be effective. [6, 25] If the intervention is successfully reducing a dangerous behavior (e.g., aggression, self-injury) or increasing a critical skill, withdrawing it to return to baseline conditions could pose a risk to the client's safety or reverse their progress. [7, 8]

Question 3: A BCBA is calculating interobserver agreement (IOA) for frequency data collected on a client's manding behavior. Observer A recorded 8 mands, and Observer B recorded 10 mands during the same observation period. Using the total count IOA formula, what is the IOA percentage?

88%
80% (Correct answer)
125%
90%

Correct answer: 80%

The formula for Total Count IOA is (Smaller Count / Larger Count) * 100. In this scenario, the smaller count is 8 and the larger count is 10. Therefore, the calculation is (8 / 10) * 100, which equals 80%.

Question 4: A BCBA is teaching a client to wash their hands. The BCBA provides reinforcement only after the client completes the final step of the task, drying their hands. All preceding steps are prompted. Which behavior-change procedure is the BCBA using?

Shaping
Forward chaining
Backward chaining (Correct answer)
Total task chaining

Correct answer: Backward chaining

Backward chaining is a procedure where the last step in a behavioral chain is taught first, and once mastered, the second-to-last step is taught, and so on, until the entire chain is learned. Reinforcement is delivered upon completion of the terminal step.

Question 5: A student receives a sticker after every 5 correct math problems. This is an example of which reinforcement schedule?

Variable ratio VR-5
Fixed interval FI-5
Variable interval VI-5
Fixed ratio FR-5 (Correct answer)

Correct answer: Fixed ratio FR-5

A fixed ratio schedule delivers reinforcement after a set, predictable number of responses — in this case, every 5 correct problems regardless of time elapsed.

Question 6: Which term describes a class of stimuli that each occasion the same response because they share a common history of reinforcement?

Conditioned stimulus class
Functional stimulus class (Correct answer)
Arbitrary stimulus class
Stimulus equivalence class

Correct answer: Functional stimulus class

A functional stimulus class is defined by a shared behavioral function (each member evokes the same response) rather than by physical similarity.

Question 7: When using an alternating treatments design, a potential confounding variable is that the effects of one treatment may carry over and influence the subject's behavior when the other treatment is presented. This is known as:

Observer Drift
Multiple Treatment Interference (Correct answer)
Procedural Infidelity
Maturation

Correct answer: Multiple Treatment Interference

Multiple treatment interference is a potential threat to internal validity in designs where two or more treatments are alternated, such as the alternating treatments design. [2] It occurs when the effects of one treatment are influenced by the presence of the other treatments being used in the same study, making it difficult to isolate the independent effects of each intervention. [17, 22]

Question 8: The key distinction between a descriptive assessment and a functional analysis is that a descriptive assessment identifies _, whereas a functional analysis identifies _.

causation; function
function; correlation
correlation; a functional relation (Correct answer)
hypotheses; causation

Correct answer: correlation; a functional relation

Descriptive assessments involve observing and recording behavior as it naturally occurs, which can reveal correlations between environmental events and the behavior. A functional analysis goes a step further by systematically manipulating variables to demonstrate a causal, or functional, relation between those variables and the behavior.

Question 9: A contingency contract:

often causes scapegoating among learners and peers
specifies how two people will behave toward each other (Correct answer)
depends largely on the use of punishment for its effectiveness
is a verbal agreement between two individuals

Correct answer: specifies how two people will behave toward each other

Explanation: A contingency contract is a formal agreement that outlines the expected behavior and responsibilities of two individuals towards each other. It sets clear expectations and consequences for both parties involved, ensuring that they understand their roles and obligations. This contract helps establish a structured and predictable environment, promoting accountability and cooperation between the individuals.

Question 10: In a concurrent schedule of reinforcement, the individual:

Completes a chain of responses before any reinforcement is delivered
Receives reinforcement from alternating schedules delivered in sequence
Must complete one schedule fully before accessing a second schedule
Has simultaneous access to two or more independent reinforcement schedules (Correct answer)

Correct answer: Has simultaneous access to two or more independent reinforcement schedules

Concurrent schedules involve two or more independent reinforcement schedules operating simultaneously, providing the individual with a choice between response alternatives at the same time.

Question 11: Overcorrection is classified as which type of behavior-reduction procedure?

Extinction
Negative punishment
Positive punishment (Correct answer)
Negative reinforcement

Correct answer: Positive punishment

Overcorrection (restitution and positive practice) is a positive punishment procedure because an aversive activity is added contingent on problem behavior.

Question 12: A BCBA is designing a functional behavior assessment (FBA) for a client who engages in infrequent but severe aggressive outbursts. Direct observation has been challenging due to the low rate of the behavior. To develop a preliminary hypothesis about the function of the behavior, which assessment procedure would be the MOST appropriate first step?

Administering a functional assessment screening tool (FAST) to caregivers. (Correct answer)
Initiating a reinforcer assessment to identify high-preference items.
Conducting a trial-based functional analysis in a controlled setting.
Implementing a descriptive assessment using ABC narrative recording in the natural environment.

Correct answer: Administering a functional assessment screening tool (FAST) to caregivers.

Administering a functional assessment screening tool (FAST) or other indirect assessment methods like interviews and rating scales is the most appropriate first step when behavior is infrequent and direct observation is difficult. These tools gather information from caregivers to form a hypothesis about the variables maintaining the behavior, which can then guide further, more direct assessment methods. A functional analysis is an experimental method and may not be the first choice, while a descriptive assessment requires the behavior to be observed directly. A reinforcer assessment identifies potential rewards but does not determine the function of the problem behavior.

Question 13: A BCBA is tasked with identifying the function of a student's aggressive behavior, which occurs at a high rate and poses a risk of injury. The BCBA decides to systematically manipulate antecedents and consequences in a controlled setting to test hypotheses about what is maintaining the behavior. Which behavioral assessment method is the BCBA employing?

Functional Analysis (Correct answer)
Descriptive Assessment
Indirect Assessment
Ecological Assessment

Correct answer: Functional Analysis

A functional analysis is the only assessment method that involves the systematic manipulation of environmental variables (antecedents and consequences) to demonstrate a cause-and-effect relationship between the environment and the behavior. Descriptive and indirect assessments can generate hypotheses, but they do not directly test them.

Question 14: A BCBA is designing a study to evaluate the effectiveness of an intervention. A potential threat to internal validity is 'history.' Which of the following scenarios BEST illustrates this threat?

The participant shows improvement in social skills, which may be due to their natural cognitive and emotional development.
The participant becomes more familiar with the testing procedures over time, leading to improved performance.
The observers collecting data subtly change their definition of the target behavior over the course of the study.
While the intervention is being implemented at school, the participant's parents begin a new, similar behavior plan at home. (Correct answer)

Correct answer: While the intervention is being implemented at school, the participant's parents begin a new, similar behavior plan at home.

History, as a threat to internal validity, refers to any external event that occurs during the course of an experiment that is not part of the manipulation and could be responsible for the results. The implementation of a similar behavior plan at home is an outside event that could confound the effects of the school-based intervention.

Question 15: Which stimulus control concept describes a learner responding correctly to a trained stimulus but not to similar untrained stimuli?

Stimulus equivalence
Stimulus discrimination (Correct answer)
Stimulus overselectivity
Stimulus generalization

Correct answer: Stimulus discrimination

Stimulus discrimination occurs when a behavior is emitted in the presence of the SD but not in the presence of stimuli that were not reinforced.

Question 16: What response pattern is typically associated with fixed interval (FI) schedules?

Steady high rate throughout the interval
Constant low rate of responding
Irregular bursts with long pauses
Scalloped pattern with a post-reinforcement pause (Correct answer)

Correct answer: Scalloped pattern with a post-reinforcement pause

Fixed interval schedules produce a scalloped pattern: a pause after reinforcement, then gradually increasing responding as the end of the interval approaches.

Question 17: A client is learning to say the word "bubble." The behavior analyst first reinforces any vocalization, then reinforces "buh," then "buh-buh," and finally, only reinforces the full word "bubble." This process is best described as:

Shaping (Correct answer)
Chaining
Prompting
Modeling

Correct answer: Shaping

Shaping is the process of differentially reinforcing successive approximations to a terminal behavior. In this scenario, the analyst is reinforcing closer and closer approximations of the target word, "bubble," starting from a behavior already in the client's repertoire (vocalizing).

Question 18: In a token economy, tokens function as:

Conditioned reinforcers earned for target behaviors and exchanged for backup reinforcers (Correct answer)
Naturally occurring consequences that do not require exchange
Unconditioned reinforcers with intrinsic value
Primary reinforcers delivered immediately after behavior

Correct answer: Conditioned reinforcers earned for target behaviors and exchanged for backup reinforcers

Tokens are conditioned (generalized) reinforcers that acquire value through their association with backup reinforcers and can be exchanged for those backup reinforcers at a later time.

Question 19: Under the BACB's Ethics Code for Behavior Analysts, which of the following is an unacceptable practice regarding the use of client testimonials?

Sharing a former client's success story at a professional conference with all identifying information removed.
Using an anonymous testimonial from a current client in a grant application for a non-profit organization.
Using a testimonial from a former client in an advertisement after obtaining their consent and specifying if it was solicited.
Using an unsolicited positive review from a current client's parent, found on a public website, in a new promotional brochure. (Correct answer)

Correct answer: Using an unsolicited positive review from a current client's parent, found on a public website, in a new promotional brochure.

The BACB Ethics Code prohibits behavior analysts from soliciting or using testimonials from current clients for advertising purposes due to the potential for undue influence. Even if a testimonial is unsolicited and publicly available, repurposing it for the behavior analyst's own advertising materials is a violation. Testimonials from former clients may be used for advertising under specific conditions, and testimonials from current clients may be used for non-advertising purposes like grant applications.

Question 20: A behavior analyst is working with a new client who is nonverbal and has difficulty making choices. The analyst wants to identify potential reinforcers. They decide to present one item at a time and record the duration of the client's engagement with each item. Which type of preference assessment is being used?

Paired Stimulus
Multiple Stimulus Without Replacement (MSWO)
Single Stimulus (Successive Choice) (Correct answer)
Free Operant

Correct answer: Single Stimulus (Successive Choice)

The single stimulus, or successive choice, preference assessment involves presenting items one at a time and measuring the individual's reaction, such as duration of engagement. This method is particularly useful for individuals who have difficulty choosing between multiple items presented simultaneously.

Question 21: A BCBA is supervising a BCaBA who discloses that they are going through a difficult personal matter that is causing them significant distress. The BCBA has noticed a decline in the BCaBA's performance, including missed deadlines and data errors. What is the BCBA's primary ethical responsibility in this situation?

Ignore the personal disclosure and only provide corrective feedback on the work-related errors.
Immediately terminate the supervisory relationship and report the BCaBA to the BACB for being impaired.
Recommend that the BCaBA take an indefinite leave of absence from all work.
Address the performance issues with the BCaBA and explore solutions, which may include recommending they seek support for their personal problems and possibly modifying work responsibilities. (Correct answer)

Correct answer: Address the performance issues with the BCaBA and explore solutions, which may include recommending they seek support for their personal problems and possibly modifying work responsibilities.

The BCBA's ethical obligation is to protect clients by addressing the supervisee's performance deficits. This must be done professionally and supportively. The best course of action involves discussing the performance problems, exploring ways to resolve them (e.g., modified duties, additional support), and recommending the supervisee seek help for personal issues that impact their professional competence, as outlined in the BACB Ethics Code regarding impairment and maintaining competence.

Question 22: Little Peter was walking along the fence of his uncle's dairy farm. Peter reached up and grabbed the wire along the fence, not realizing it was electrified. After recovering from the pain caused by the shock, Peter never again touched the fence wires. Which statement best describes the shock stimulus felt by Peter?

Positive punishment (Correct answer)
Negative reinforcement
Bad judgement
Negative punishment

Correct answer: Positive punishment

Explanation: The shock stimulus felt by Peter can be described as positive punishment because it involved the application of an aversive stimulus (electric shock) to decrease the likelihood of a behavior (touching the fence wires) in the future.

Question 23: Which statement best describes recovery from punishment?

The period of time the implementer of the punishment contingency requires to "recover" from the emotional side effects of using punishment.
After punishment is discontinued, sometimes the behavior that experienced the punishment contingency will recover. (Correct answer)
After punishment is discontinued, the behavior of interest may gradually reappear, only to disappear on its own, regardless of existing environmental contingencies.
When the punishment contingency is implemented, the behavior of interest may initially increase in rate, followed by a rapid decline in frequency.

Correct answer: After punishment is discontinued, sometimes the behavior that experienced the punishment contingency will recover.

Explanation: After punishment is discontinued, sometimes the behavior that experienced the punishment contingency will recover. This means that the behavior that was punished may start to occur again after the punishment has stopped.

Question 24: A behavior analyst is establishing a data collection system and wants to ensure that the measurement is consistently applied across observers. This refers to which quality of measurement?

Reliability (Correct answer)
Validity
Accuracy
Social Validity

Correct answer: Reliability

Reliability refers to the consistency of a measurement. High reliability means that different observers, or the same observer at different times, will record the same value for the same event. It is about the repeatability of the measurement procedure.

Question 25: When visually analyzing a line graph of behavior data, what does 'level' refer to?

The value on the vertical axis around which a set of behavioral measures converge. (Correct answer)
The point at which the intervention was introduced.
The degree of fluctuation or scatter of the data points around the mean.
The overall direction taken by the data path.

Correct answer: The value on the vertical axis around which a set of behavioral measures converge.

Level refers to the value on the vertical axis (y-axis) around which the data points tend to converge. It essentially represents the average magnitude or rate of the behavior during a specific condition or phase. 'Variability' describes the fluctuation of data points, and 'trend' refers to the overall direction of the data path. The point of intervention is marked by a phase change line, not the level.

Question 26: The process by which a neutral stimulus acquires discriminative control through pairing with an existing SD is called:

Conditional discrimination (Correct answer)
Blocking
Stimulus fading
Higher-order conditioning

Correct answer: Conditional discrimination

Conditional discrimination (also called stimulus-stimulus pairing in some contexts) establishes new SDs by pairing neutral stimuli with stimuli that already control responding.

Question 27: All of the following are defining features of single-case experimental designs EXCEPT:

repeated measures are taken over time.
experimental control is demonstrated through replication within the design.
the participant serves as their own control.
the use of large, randomized control groups. (Correct answer)

Correct answer: the use of large, randomized control groups.

Single-case designs are characterized by the individual participant serving as their own control, the use of repeated measures to establish data paths, and the demonstration of experimental control through prediction, verification, and replication within the design. Large, randomized control groups are characteristic of group designs, not single-case designs.

Question 28: A behavior analyst is interested in the total amount of time a student engages in stereotypy during a 30-minute observation. The behavior is continuous and varies in duration. Which measurement system would provide the most accurate data for this specific dimension of behavior?

Partial Interval Recording
Momentary Time Sampling
Duration Recording (Correct answer)
Frequency

Correct answer: Duration Recording

Duration recording is a continuous measurement procedure that tracks the total time a behavior occurs from its onset to its offset. Since the analyst is interested in the total amount of time, this is the most direct and accurate method. Frequency would only count the instances, while partial interval and momentary time sampling would only provide an estimate, not the exact total time.

Question 29: A researcher is conducting a study over a 12-month period to increase the social interactions of a young child. The researcher observes a steady increase in social interactions over the year. However, during this time, the child also starts attending a new preschool program known for its focus on social skills. The potential influence of the new preschool on the child's behavior is an example of which threat to internal validity?

Maturation
History (Correct answer)
Instrumentation
Testing

Correct answer: History

History refers to any external event that occurs during the course of an experiment that is not part of the intervention but may affect the dependent variable. [28, 29] In this case, the child's attendance at a new preschool is an uncontrolled event that could plausibly account for the observed increase in social interactions, confounding the effects of the intended intervention.

Question 30: A BCBA supervisor observes a supervisee consistently making errors during the implementation of a differential reinforcement of alternative behavior (DRA) procedure. The supervisor has already provided verbal instructions and a written protocol. According to performance management principles, what is the most appropriate next step for the supervisor?

Implement a punishment procedure for incorrect implementation.
Instruct the supervisee to read more research articles about DRA.
Model the correct implementation of the DRA procedure and have the supervisee rehearse it. (Correct answer)
Re-assign the supervisee to a different client with a less complex case.

Correct answer: Model the correct implementation of the DRA procedure and have the supervisee rehearse it.

This is correct because after providing instructions (which failed), the next logical steps in effective training and performance management are modeling the correct skill and providing opportunities for rehearsal with feedback. This is a core part of Behavior Skills Training (BST), a research-based method for training staff.

Question 31: ________________ involves collecting baselines on the same behavior of several persons, preferably in different settings.

Reversal design
Multiple-baseline across individual design (Correct answer)
Multiple-baseline across behaviors design
Alternating treatments design

Correct answer: Multiple-baseline across individual design

Explanation: The correct answer is Multiple-baseline across individuals design. This design involves collecting baselines on the same behavior of several persons, preferably in different settings. By doing so, it allows researchers to establish a cause-and-effect relationship between the independent variable and the behavior being studied. This design is particularly useful when it is not possible or ethical to use a control group or when the behavior being studied is rare or occurs infrequently.

Question 32: Which form of verbal behavior is evoked by a verbal discriminative stimulus and has point-to-point correspondence and formal similarity with the response?

Echoic (Correct answer)
Tact
Mand
Intraverbal

Correct answer: Echoic

Explanation: Echoic behavior refers to the form of verbal behavior that is evoked by a verbal discriminative stimulus and has point-to-point correspondence and formal similarity with the response. In other words, when someone repeats or echoes the words or sounds they hear, it is considered echoic behavior. This type of verbal behavior is important for language development and learning, as it helps individuals acquire new words and sounds by imitating what they hear.

Question 33: A BCBA provides in-home services to a child. The child's parents, who are very pleased with the services, offer the BCBA a standing invitation to have free meals at their family-owned restaurant. According to the BACB Ethics Code, what is the BCBA's most appropriate course of action?

Suggest that the parents instead provide a positive review online for the agency.
Accept the offer, as it is a gift of service rather than a monetary gift, and does not violate the code.
Accept the offer as a kind gesture, but limit it to once a month to maintain professionalism.
Politely decline the offer, explaining the ethical guidelines regarding multiple relationships and conflicts of interest. (Correct answer)

Correct answer: Politely decline the offer, explaining the ethical guidelines regarding multiple relationships and conflicts of interest.

The BACB Ethics Code strictly prohibits multiple relationships that could impair objectivity, create a conflict of interest, or lead to exploitation. Accepting gifts or services from clients, even if well-intentioned, creates a dual relationship beyond the professional one. The most ethical action is to politely decline and explain the professional boundaries that must be maintained to protect the integrity of the therapeutic relationship.

Question 34: Which of the following is a primary advantage of using a multiple baseline design over a reversal (A-B-A-B) design?

It is more effective for comparing the effects of two or more different interventions.
It provides a more powerful demonstration of experimental control.
It does not require the withdrawal of an effective intervention. (Correct answer)
It is the only design that allows for the analysis of prediction, verification, and replication.

Correct answer: It does not require the withdrawal of an effective intervention.

A key advantage of the multiple baseline design is that it does not require withdrawing the intervention once it has been implemented. This is particularly important from an ethical standpoint when dealing with severe challenging behaviors (e.g., self-injury) or when it is undesirable to reverse newly acquired skills.

Question 35: Non-contingent reinforcement (NCR) reduces problem behavior primarily by:

Abolishing the motivating operation maintaining problem behavior (Correct answer)
Teaching an alternative communication response
Punishing the behavior directly
Placing the behavior on extinction

Correct answer: Abolishing the motivating operation maintaining problem behavior

NCR delivers the reinforcer on a time-based schedule independent of behavior, which serves as an abolishing operation that reduces the value of that reinforcer and the problem behavior it maintains.

Question 36: A BCBA is supervising a trainee who is accruing fieldwork hours. The BCBA notices the trainee consistently struggles with data analysis and graphing. To comply with their ethical obligations as a supervisor, the BCBA must:

sign off on the hours anyway, as long as the trainee's direct intervention skills are strong.
provide ongoing, constructive feedback and design systems to improve the trainee's performance. (Correct answer)
delegate these tasks to another, more competent trainee.
recommend the trainee find a different supervisor who is better at teaching data analysis.

Correct answer: provide ongoing, constructive feedback and design systems to improve the trainee's performance.

According to the BACB Ethics Code (Section 4), supervisors are responsible for the professional development of their trainees. This includes designing effective supervision, providing timely and constructive feedback to improve performance, and ensuring supervisees develop the necessary skills for competent practice. Delegating the task without addressing the skill deficit, recommending a new supervisor without attempting to train, or ignoring the issue are all abdications of this responsibility.

Question 37: A verbal operant under the control of a motivating operation that is reinforced by a generalized conditioned reinforcer is called a:

Tact
Mand (Correct answer)
Echoic
Intraverbal

Correct answer: Mand

A mand is controlled by a motivating operation and produces the specific reinforcer related to that operation.

Question 38: A behavior analyst is conducting a paired-stimulus preference assessment with a child to identify potential reinforcers. The assessment involves presenting two items at a time and recording which item the child chooses. If the child consistently fails to make a selection within the allotted 5-second interval, even after being prompted to sample each item, what is the standard procedural step to take for that specific trial?

Leave the items in front of the child until a choice is made, regardless of time.
Remove both items and present a new pair from the list. (Correct answer)
End the assessment immediately and conclude the child has no preferences.
Prompt the child to select the item on the right to keep the assessment moving.

Correct answer: Remove both items and present a new pair from the list.

In a paired-stimulus (or forced-choice) preference assessment, if a client does not choose an item after the initial presentation and a subsequent sampling presentation, the standard procedure is to remove both stimuli and move on to the next pairing in the sequence. This ensures the assessment proceeds efficiently and avoids assigning preference where none was demonstrated. Continuing to wait or forcing a choice would invalidate the results for that trial.

Question 39: Which experimental design is most appropriate for evaluating the effect of video modeling on the acquisition of the skills for preparing a meal by adults with developmental disabilities?

Changing criterion
Delayed multiple baselines
Multiple probe (Correct answer)
Multiple baselines across behaviors

Correct answer: Multiple probe

Explanation: A multiple-probe experimental design would be the most appropriate for evaluating the effect of video modeling on the acquisition of skills for preparing a meal by adults with developmental disabilities. This design involves introducing the intervention (video modeling) at different times for different behaviors or participants, allowing for a staggered implementation. This design is useful when it is not feasible or ethical to withdraw the intervention once it has been effective for one behavior or participant. By using a multiple probe design, researchers can assess the effectiveness of video modeling on the acquisition of meal preparation skills in a systematic and controlled manner.

Question 40: Which of the following assessments is specifically designed to evaluate a learner's performance on tasks directly taken from their existing academic or daily living skills curriculum?

Paired-Stimulus Preference Assessment
Functional Analysis
Curriculum-Based Assessment (CBA) (Correct answer)
Vineland Adaptive Behavior Scales

Correct answer: Curriculum-Based Assessment (CBA)

A Curriculum-Based Assessment (CBA) is an assessment method that directly evaluates a student's performance on skills from their existing curriculum. This allows practitioners to pinpoint specific skill deficits within the curriculum and monitor progress on instructional objectives. Functional analysis identifies behavioral function, preference assessments identify reinforcers, and the Vineland is a standardized assessment of adaptive behavior, not a direct measure of curriculum-specific tasks.

Question 41: Which dimension of the BACB's definition of behavior analysis most directly supports using antecedent interventions before punishment?

Analytic
Applied (Correct answer)
Behavioral
Technological

Correct answer: Applied

The 'applied' dimension emphasizes social significance and ethical practice, which includes preference for less intrusive antecedent strategies before resorting to punishment.

Question 42: A behavior analyst wants to quickly compare the effectiveness of two different function-based interventions for reducing a student's off-task behavior: differential reinforcement of alternative behavior (DRA) and noncontingent reinforcement (NCR). Which experimental design would be the most efficient for this purpose?

Alternating treatments design (Correct answer)
Multiple baseline across behaviors design
Changing criterion design
Reversal (A-B-A-B) design

Correct answer: Alternating treatments design

The alternating treatments design (also known as a multielement design) is the most appropriate choice for directly and efficiently comparing the effects of two or more distinct interventions. It involves the rapid and random alternation of the conditions, allowing for a clear comparison within a short period.

Question 43: _________________is an experimental design in which two or more conditions are presented in rapidly alternating succession independent of the level of responding.

Multiple baselines across settings
Alternating treatments design (Correct answer)
Withdrawal design
Reversal design

Correct answer: Alternating treatments design

Explanation: The alternating treatments design is an experimental design where two or more conditions are presented in rapidly alternating succession, regardless of the level of response. This design allows for the comparison of the effects of different conditions on the same individual or group, by quickly switching between the conditions. It is useful in situations where it is not feasible or ethical to withdraw the treatment and provides a more efficient way to evaluate the effectiveness of different interventions or treatments.

Question 44: A behavior analyst implements an extinction procedure for a client's attention-maintained disruptive behavior. Initially, the frequency and intensity of the disruptive behavior increase dramatically before starting to decrease. This temporary increase in the behavior is known as:

Resurgence
Spontaneous recovery
Response generalization
Extinction burst (Correct answer)

Correct answer: Extinction burst

An extinction burst is a common and temporary effect of an extinction procedure where the frequency, intensity, or duration of the behavior increases before it begins to decrease. It occurs because the individual is escalating the behavior in an attempt to contact the reinforcement that was previously available.

Question 45: A behavior analyst is working with a client who engages in self-injurious behavior (SIB). The analyst wants to compare the effects of two different interventions (DRA and blocking) and a baseline condition. Given the severity of the behavior, withdrawing an effective intervention would be unethical. Which experimental design would be most appropriate for simultaneously comparing the interventions while minimizing ethical risks?

Multiple Baseline Design
Alternating Treatments Design (Correct answer)
Changing Criterion Design
A-B-A-B Reversal Design

Correct answer: Alternating Treatments Design

An alternating treatments design (also known as a multielement design) is the most appropriate choice because it allows for the rapid alternation of two or more interventions or conditions, enabling a quick comparison of their effects. [19] It does not require a lengthy withdrawal phase, which is crucial when dealing with dangerous behaviors like SIB, thus addressing the ethical concern of removing an effective treatment. [22]

Question 46: Dr. G was a very well-known behavior analyst with a great radio voice. He was occasionally asked to handle questions about behavior problems on a local radio call-in show. To make the show lively and interesting, Dr. G took great pains to remind listeners that what he suggested was backed up by empirical research. The show's producer prompted Dr. G. to use the caller's name when giving a reply and a warm tone. He wanted Dr. G to say something like, "I know exactly what you are talking about, and I can understand how you feel". Dr. G preferred a matter-of-fact approach. What should Dr. G. do?

All of the above
Do whatever the producer says so he doesn't get fired
Continue what he is doing regardless of the outcome
Try to be "warmer" while maintaining his ethics and not making statements that suggest he knows more about the caller than he does (Correct answer)

Correct answer: Try to be "warmer" while maintaining his ethics and not making statements that suggest he knows more about the caller than he does

Explanation: Dr. G should try to be "warmer" while maintaining his ethics and not making statements that suggest he knows more about the caller than he does. This means that he should follow the producer's suggestion of using the caller's name and a warm tone, but he should not make false statements or pretend to understand the caller's feelings more than he actually does. By doing this, Dr. G can maintain a friendly and engaging demeanor on the radio show without compromising his professional integrity.

Question 47: The matching law states that organisms on concurrent schedules:

Distribute responding proportional to the relative rate of reinforcement available on each schedule (Correct answer)
Always choose the schedule with the highest fixed ratio requirement
Match the topography of modeled responses before accessing reinforcement
Respond equally across all simultaneously available schedules

Correct answer: Distribute responding proportional to the relative rate of reinforcement available on each schedule

The matching law holds that the relative rate of responding on concurrent schedules is proportional to (matches) the relative rate of reinforcement available on each alternative.

Question 48: Which schedule of reinforcement produces the highest and most consistent response rates?

Variable interval (VI)
Fixed interval (FI)
Fixed ratio (FR)
Variable ratio (VR) (Correct answer)

Correct answer: Variable ratio (VR)

Variable ratio schedules produce the highest and most consistent rates of responding because reinforcement is unpredictable, making the behavior highly resistant to extinction.

Question 49: When a problem behavior has been targeted for reduction or elimination, the behavior analyst must always include a(n) ________ in the intervention plan.

Pivotal behavior
Performance criterion
Replacement behavior (Correct answer)
Appropriate response

Correct answer: Replacement behavior

Explanation: When a problem behavior is targeted for reduction or elimination, it is important for the behavior analyst to include a replacement behavior in the intervention plan. This means identifying and teaching a more appropriate behavior to replace the problem behavior. The replacement behavior should serve the same function as the problem behavior but in a more socially acceptable way. By including a replacement behavior in the intervention plan, the behavior analyst can help the individual learn and engage in a more desirable behavior instead of the problem behavior.

Question 50: Contingency contracting is best defined as:

A formal, written agreement specifying target behaviors and their consequences (Correct answer)
Using only natural environmental consequences rather than programmed reinforcement
Hiring an external party to monitor and deliver reinforcement
Removing all reinforcers contingent on problem behavior occurring

Correct answer: A formal, written agreement specifying target behaviors and their consequences

Contingency contracting is a written or verbal agreement between parties that explicitly specifies the target behaviors required and the consequences (reinforcement or penalties) that will follow.

Question 51: Which concept describes the idea that punishment is most effective when delivered immediately after the behavior?

Contingency
Stimulus satiation
Immediacy (Correct answer)
Intensity gradient

Correct answer: Immediacy

The immediacy principle states that consequences—both reinforcement and punishment—have greater behavior-change effects when they follow the behavior immediately.

Question 52: A BCBA is providing services to a family in a small, rural community. The client's father is the only mechanic in town. The BCBA's car breaks down and requires immediate repair. Which of the following actions is the most appropriate for the BCBA to take to manage this potential multiple relationship?

Use the mechanic's services and accept a discount as a professional courtesy.
Immediately terminate services with the family to avoid any potential conflict of interest.
Use the mechanic's services but insist on paying the full, standard rate and document the interaction. (Correct answer)
Ask the family for a referral to a mechanic in a different town, even if it is far away.

Correct answer: Use the mechanic's services but insist on paying the full, standard rate and document the interaction.

The BACB Ethics Code advises avoiding multiple relationships but recognizes they can be unavoidable in some situations, such as small communities. The most ethical course of action is to proceed with the necessary service while maintaining clear professional boundaries. This involves paying the standard rate, documenting the circumstances, and ensuring the professional relationship with the client remains prioritized and objective.

Question 53: Which antecedent intervention involves altering setting events or motivating operations to reduce the value of problem behavior reinforcers?

Antecedent exercise
Differential reinforcement of other behavior
Non-contingent reinforcement
Abolishing operation manipulation (Correct answer)

Correct answer: Abolishing operation manipulation

Manipulating abolishing operations (AOs) reduces the effectiveness of the reinforcer maintaining problem behavior, thereby decreasing the likelihood of that behavior.

Question 54: A BCBA is designing a token economy for a classroom setting. Which of the following is the MOST critical first step in this process?

Creating a visual token board for the students.
Identifying and operationally defining the target behaviors. (Correct answer)
Selecting the type of tokens to be used.
Establishing the exchange rate for backup reinforcers.

Correct answer: Identifying and operationally defining the target behaviors.

Before any other component of the token economy can be designed, the specific target behaviors must be clearly identified and defined in observable and measurable terms. This ensures that both the staff and the students understand which behaviors will earn tokens.

Question 55: Which of the following is not a factor that influences the effectiveness of punishment?

Immediacy
Intensity
Schedule
Variation (Correct answer)

Correct answer: Variation

Explanation: Variation is not a factor that influences the effectiveness of punishment. Immediacy refers to how quickly the punishment is administered after the behavior, intensity refers to the severity of the punishment, and schedule refers to the consistency of the punishment. However, variation refers to the different types or forms of punishment used, and it does not directly impact the effectiveness of punishment.

Question 56: A behavior analyst wants to evaluate the effectiveness of an intervention to reduce a student's disruptive behavior in three different settings: the classroom, the cafeteria, and the playground. The analyst plans to introduce the intervention at different times in each setting. This describes which experimental design?

Changing Criterion Design
Multiple Baseline Across Settings (Correct answer)
Reversal Design
Multiple Baseline Across Behaviors

Correct answer: Multiple Baseline Across Settings

A multiple baseline across settings design involves establishing baselines for a single behavior in three or more different environments and then systematically introducing the intervention to each setting at a different point in time. [9, 13] This allows the analyst to demonstrate experimental control by showing that the behavior changes only when the intervention is implemented in that specific setting. [23]

Question 57: Differential Reinforcement of Other behavior (DRO) is defined as delivering reinforcement:

Only for behaviors incompatible with the target behavior
Only for a specific alternative behavior
For low rates of the target behavior
Contingent on the absence of the target behavior during a set interval (Correct answer)

Correct answer: Contingent on the absence of the target behavior during a set interval

DRO delivers reinforcement at the end of an interval during which the target problem behavior did not occur, reinforcing the absence of the behavior rather than a specific alternative.

Question 58: A client has a history of screaming to gain access to a preferred toy. The BCBA decides to reinforce the client for handing a picture card of the toy to an adult and ignores all instances of screaming. This is an example of which differential reinforcement procedure?

Differential Reinforcement of Low Rates of Behavior (DRL)
Differential Reinforcement of Other Behavior (DRO)
Differential Reinforcement of Alternative Behavior (DRA) (Correct answer)
Differential Reinforcement of Incompatible Behavior (DRI)

Correct answer: Differential Reinforcement of Alternative Behavior (DRA)

Differential Reinforcement of Alternative Behavior (DRA) involves reinforcing a specific, appropriate alternative behavior that serves the same function as the problem behavior, while placing the problem behavior on extinction. In this case, handing a picture card is an alternative way to request the toy.

Question 59: A BCBA is reviewing a line graph that displays data from a functional analysis. The data path for the 'attention' condition shows a consistently high and stable level, while the data paths for all other conditions remain low and near zero. What is the most appropriate interpretation of these data?

A clear function cannot be determined from the graph.
The behavior is likely maintained by access to tangible items.
The behavior is maintained by automatic reinforcement.
The behavior is likely maintained by social positive reinforcement (attention). (Correct answer)

Correct answer: The behavior is likely maintained by social positive reinforcement (attention).

Visual analysis of a functional analysis graph involves comparing the data paths across different conditions. A high and stable data path in one condition, while others remain low, suggests that the variable manipulated in that condition is the reinforcer for the behavior. In this case, the 'attention' condition shows the highest level of behavior, indicating it is maintained by attention, a form of social positive reinforcement.

Question 60: Positive reinforcement is correctly defined as:

Removing an aversive stimulus to increase future behavior
Withholding reinforcement to reduce unwanted behavior
Adding a preferred stimulus following a behavior to increase its future frequency (Correct answer)
Presenting an aversive stimulus following behavior to decrease it

Correct answer: Adding a preferred stimulus following a behavior to increase its future frequency

Positive reinforcement is the contingent presentation of a stimulus following a behavior that increases the future frequency of that behavior.

Question 61: A supervisor is using Behavior Skills Training (BST) to teach a new RBT how to conduct a multiple stimulus without replacement (MSWO) preference assessment. Which of the following components is essential for the supervisor to include?

Providing immediate, performance-based feedback after the RBT rehearses the skill. (Correct answer)
Having the RBT watch several videos of other technicians performing the assessment.
Ensuring the RBT can verbally describe the procedure with 100% accuracy before trying it.
A final written exam on the steps of the MSWO procedure.

Correct answer: Providing immediate, performance-based feedback after the RBT rehearses the skill.

Behavior Skills Training (BST) is an evidence-based training package consisting of four components: instructions, modeling, rehearsal, and feedback. Providing specific, performance-based feedback immediately following the supervisee's rehearsal of the skill is critical for shaping correct performance and is an essential part of the BST process.

Question 62: Which of the following correctly distinguishes a preference assessment from a reinforcer assessment?

A preference assessment identifies which stimuli an individual will work for, while a reinforcer assessment determines what they like the most.
A preference assessment is only conducted using indirect methods, while a reinforcer assessment must involve direct observation and data collection.
A preference assessment measures the effect of a stimulus on increasing future behavior, while a reinforcer assessment identifies a hierarchy of liked items.
A preference assessment identifies potential reinforcers by observing choice behavior, while a reinforcer assessment directly tests if a stimulus increases responding. (Correct answer)

Correct answer: A preference assessment identifies potential reinforcers by observing choice behavior, while a reinforcer assessment directly tests if a stimulus increases responding.

A preference assessment is used to identify stimuli that an individual is likely to prefer or choose, creating a hierarchy of potential reinforcers. However, it does not confirm that these items will function to increase behavior. A reinforcer assessment is a separate, direct test to determine if a specific stimulus, when presented contingently, actually increases the future frequency of a behavior.

Question 63: Which procedure involves the systematic removal of a preferred item or activity contingent on problem behavior?

Time-out from positive reinforcement
Response cost (Correct answer)
Extinction
Overcorrection

Correct answer: Response cost

Response cost is a penalty-based punishment procedure in which a specified amount of a conditioned positive reinforcer is removed following problem behavior.

Question 64: DRI (Differential Reinforcement of Incompatible behavior) requires that the alternative behavior:

Cannot physically occur at the same time as the problem behavior (Correct answer)
Is easier to perform than the problem behavior
Occurs at a lower rate than the problem behavior
Produces a different reinforcer than the problem behavior

Correct answer: Cannot physically occur at the same time as the problem behavior

In DRI, the reinforced response must be topographically incompatible with the problem behavior, meaning both cannot occur simultaneously.

Question 65: Continuous reinforcement (CRF) is MOST appropriate during which phase of learning?

Maintenance phase to keep behavior stable long-term
Fluency phase to increase response speed
Acquisition phase to initially establish a new behavior (Correct answer)
Generalization phase to extend behavior to new settings

Correct answer: Acquisition phase to initially establish a new behavior

CRF is most effective during acquisition because reinforcing every correct response provides immediate and consistent feedback, rapidly strengthening the new behavior.

Question 66: Non-contingent reinforcement involves the presentation of:

Stimuli with known reinforcing properties that are delivered on a fixed-time or variable-time schedule independent of the learner's behavior (Correct answer)
Stimuli with known reinforcing properties that are delivered on a fixed-time or variable-time schedule dependent on the learner's behavior
Stimuli with known reinforcing properties that are not delivered on a fixed-ratio or variable-ratio schedule independent of the learner's behavior
Stimuli with unknown reinforcing properties that are delivered on a fixed-time or variable-time schedule independent of the learner's behavior

Correct answer: Stimuli with known reinforcing properties that are delivered on a fixed-time or variable-time schedule independent of the learner's behavior

Explanation: Non-contingent reinforcement involves delivering stimuli with known reinforcing properties on a fixed-time or variable-time schedule, regardless of the learner's behavior. This means that the reinforcement is not contingent upon any specific behavior or response from the learner. Instead, the reinforcement is provided at predetermined intervals, regardless of what the learner is doing. This can be useful in certain situations, such as when trying to maintain a behavior or when the learner is unable to engage in the desired behavior.

Question 67: Planned ignoring is most appropriate as an intervention when problem behavior is maintained by:

Automatic sensory stimulation
Escape from demands
Adult attention (Correct answer)
Access to preferred items

Correct answer: Adult attention

Planned ignoring withholds social attention as the reinforcer; it is only effective when the function of problem behavior is attention-seeking.

Question 68: Which form of verbal behavior is evoked by a verbal discriminative stimulus and does not have point-to-point correspondence with that verbal stimulus?

Mand
Tact
Echoic
Intraverbal (Correct answer)

Correct answer: Intraverbal

Explanation: Intraverbal behavior refers to a form of verbal behavior that is evoked by a verbal discriminative stimulus but does not have a point-to-point correspondence with that stimulus. This means that the response is not a direct repetition or imitation of the stimulus, but rather a related or associated verbal response. It involves generating language based on the context or meaning of the stimulus, such as answering questions, having conversations, or providing descriptions.

Question 69: A behavior analyst is working with a 14-year-old client who has the ability to verbally express their wishes. The client's legal guardians have provided informed consent for a new intervention. When the BCBA introduces the procedure, the client says, "I don't like this, and I don't want to do it." What is the BCBA's ethical obligation?

Proceed with the intervention, as legal consent from the guardians is sufficient.
Acknowledge the client's dissent, pause the procedure, and attempt to gain assent by explaining the rationale in a way the client can understand or modifying the procedure. (Correct answer)
Discontinue services immediately because the client is refusing to participate.
Inform the client that participation is not optional and immediately implement the procedure as planned.

Correct answer: Acknowledge the client's dissent, pause the procedure, and attempt to gain assent by explaining the rationale in a way the client can understand or modifying the procedure.

While informed consent is obtained from legal guardians, behavior analysts have a responsibility to seek the client's assent, which is their agreement to participate. When a client with the capacity to express themselves dissents (refuses), the BCBA must respect this refusal. The ethical course of action is to pause, acknowledge the client's feelings, and work to gain their willing participation, which may involve further explanation or modification of the plan. Overriding the client's dissent without attempting to gain assent is contrary to the principle of treating clients with dignity and respect.

Question 70: A child fills in 'twinkle twinkle little ___' when prompted by the phrase. Which verbal operant best describes this response?

Echoic
Intraverbal (Correct answer)
Mand
Tact

Correct answer: Intraverbal

An intraverbal is a verbal response to a verbal antecedent where the response does not match the antecedent (non-echoing, non-transcriptive).

Question 71: Which differential reinforcement procedure is MOST appropriate when the goal is to teach a specific replacement behavior that physically cannot occur simultaneously with the problem behavior?

DRH (Differential Reinforcement of High rates)
DRL (Differential Reinforcement of Low rates)
DRI (Differential Reinforcement of Incompatible behavior) (Correct answer)
DRO (Differential Reinforcement of Other behavior)

Correct answer: DRI (Differential Reinforcement of Incompatible behavior)

DRI reinforces a behavior that is physically incompatible with (cannot co-occur with) the problem behavior, making it ideal for establishing specific replacement skills that prevent the target behavior.

Question 72: Which of the following best defines an extinction burst?

A temporary increase in frequency, intensity, or variability of behavior at the start of extinction (Correct answer)
A reappearance of behavior weeks after successful extinction
A gradual decrease in response rate during extinction
The complete cessation of behavior after repeated extinction sessions

Correct answer: A temporary increase in frequency, intensity, or variability of behavior at the start of extinction

An extinction burst is the immediate temporary increase in responding—often accompanied by emotional behavior and response variation—that occurs at the onset of extinction.

Question 73: Which of the following is a primary advantage of using a continuous measurement procedure over a discontinuous measurement procedure?

It provides a complete and accurate record of every instance of the target behavior. (Correct answer)
It is less labor-intensive for the observer.
It is more efficient when observing multiple behaviors or individuals simultaneously.
It is best suited for high-rate behaviors that are difficult to count individually.

Correct answer: It provides a complete and accurate record of every instance of the target behavior.

Continuous measurement, such as frequency or duration recording, captures every single instance of a behavior during the observation period. This provides a more complete and accurate representation of the behavior compared to discontinuous methods (e.g., interval recording, time sampling), which only capture a sample and can either overestimate or underestimate the true occurrence of the behavior.

Question 74: Blocking, in stimulus control research, refers to:

Preventing a new stimulus from gaining discriminative control due to a pre-trained stimulus (Correct answer)
Stopping unwanted behavior by physical intervention
Scheduling reinforcement to prevent satiation
Pairing stimuli to create conditioned reinforcers

Correct answer: Preventing a new stimulus from gaining discriminative control due to a pre-trained stimulus

Blocking occurs when prior training with one stimulus prevents a second stimulus, presented in compound, from acquiring control over the response.

Question 75: Ratio strain is best described as:

Strong resistance to extinction on dense ratio schedules
Increased responding when ratio requirements are raised
The natural post-reinforcement pause on fixed ratio schedules
A breakdown in responding caused by increasing ratio requirements too rapidly (Correct answer)

Correct answer: A breakdown in responding caused by increasing ratio requirements too rapidly

Ratio strain is a deterioration in responding that occurs when ratio requirements are thinned too quickly, resulting in emotional behavior, irregular responding, or complete cessation.

Question 76: Delayed prompting with a 5-second constant delay is most directly designed to transfer stimulus control from:

The natural SD to the prompt
The learner to the teacher
The prompt to the natural SD (Correct answer)
A VR to an FR schedule

Correct answer: The prompt to the natural SD

Constant time delay inserts a brief interval between the SD and the prompt, giving the learner an opportunity to respond to the natural cue before the prompt is delivered.

Question 77: Which of the following is a key requirement for the supervision of individuals pursuing BCBA certification, according to the BACB's fieldwork standards?

The total number of supervised hours must equal at least 20% of the total fieldwork hours.
The supervisor must observe the trainee working with a client at least once per monthly supervisory period. (Correct answer)
The supervisor must have at least ten years of experience post-certification.
All supervision meetings must be conducted in a group format to promote collaboration.

Correct answer: The supervisor must observe the trainee working with a client at least once per monthly supervisory period.

The BACB's supervision standards require that supervisors directly observe their trainees implementing behavior-analytic procedures with clients during each supervisory period. This ensures that the supervisor can provide direct feedback on the trainee's performance and verify their competence.

Question 78: A stimulus change that does not elicit respondent behavior is ____________.

Punishing stimulus
S-delta
Discriminative stimulus
Neutral stimulus (Correct answer)

Correct answer: Neutral stimulus

Explanation: A neutral stimulus refers to a stimulus change that does not elicit any respondent behavior. It does not have any inherent significance or influence on the individual's behavior. In classical conditioning, a neutral stimulus becomes associated with an unconditioned stimulus to eventually elicit a conditioned response. Until this association is formed, the neutral stimulus does not elicit any response on its own.

Question 79: The least restrictive alternative principle requires behavior analysts to:

Prefer less intrusive, less restrictive procedures when equally effective alternatives exist (Correct answer)
Avoid all aversive procedures under any circumstances
Use punishment only after reinforcement has been tried for at least one year
Always choose the most effective procedure regardless of intrusiveness

Correct answer: Prefer less intrusive, less restrictive procedures when equally effective alternatives exist

The least restrictive alternative principle is an ethical guideline requiring analysts to select the most effective yet least intrusive and restrictive procedure available.

Question 80: A child throws a tantrum and the parent gives them a toy to stop the crying. From the child's perspective, this is an example of:

Negative reinforcement
Positive reinforcement (Correct answer)
Negative punishment
Positive punishment

Correct answer: Positive reinforcement

From the child's perspective, the tantrum is followed by the addition of a preferred item (toy), which will increase the future likelihood of tantrums — this is positive reinforcement.

Question 81: Equivalence-based instruction capitalizes on which property of stimulus classes?

Shaping, chaining, and prompting
Extinction, satiation, and deprivation
Transitivity, reflexivity, and symmetry (Correct answer)
Generalization, discrimination, and blocking

Correct answer: Transitivity, reflexivity, and symmetry

Derived stimulus relations (equivalence) require demonstrations of reflexivity (A=A), symmetry (if A→B then B→A), and transitivity (if A→B and B→C then A→C).

Question 82: Why is intermittent reinforcement critical for the maintenance of behavior?

It produces behavior that is more resistant to extinction than continuously reinforced behavior (Correct answer)
It speeds up initial acquisition by reinforcing every correct response
It is used exclusively during the generalization phase to promote transfer
It ensures reinforcement is delivered only for the highest quality responses

Correct answer: It produces behavior that is more resistant to extinction than continuously reinforced behavior

Intermittent reinforcement schedules produce behavior that is far more resistant to extinction than CRF because unpredictable reinforcement makes it difficult for the learner to detect when extinction has begun.

Question 83: In single-case experimental designs, the core components of baseline logic are prediction, verification, and replication. Verification is demonstrated when:

the independent variable is withdrawn, and responding returns to a level that is consistent with the original baseline. (Correct answer)
the baseline level of responding is projected to continue if the independent variable is not introduced.
the effects of the independent variable are shown across multiple different behaviors, settings, or subjects.
the intervention is implemented again, and the data pattern from the first intervention phase is reproduced.

Correct answer: the independent variable is withdrawn, and responding returns to a level that is consistent with the original baseline.

Verification involves demonstrating that the baseline level of responding would have likely remained the same had the independent variable not been introduced. In a reversal design, this is accomplished by withdrawing the intervention and observing a return to baseline levels, thus verifying the initial prediction.

Question 84: Extinction may involve which of the following:

Increase in rate of target behavior
Increase in a variety of behaviors
All of the above (Correct answer)
Increase in intensity of target behavior

Correct answer: All of the above

Explanation: Extinction refers to the process of reducing or eliminating a target behavior by withholding reinforcement. In this context, ""all of the above"" is the correct answer because extinction can result in an increase in the rate of the target behavior, an increase in the intensity of the target behavior, or an increase in a variety of other behaviors. This occurs because when reinforcement is no longer provided for the target behavior, individuals may engage in the behavior more frequently, with greater intensity, or they may try out different behaviors in an attempt to obtain the previously reinforced outcome.

Question 85: In errorless learning, a prompt is delivered _____ the natural SD to ensure the learner responds correctly from the start.

Before or simultaneously with (Correct answer)
After
Only on error trials following
Instead of

Correct answer: Before or simultaneously with

Errorless procedures present the prompt immediately before or at the same time as the SD so the learner makes the correct response before errors can occur.

Question 86: Which reinforcement schedule produces the MOST rapid extinction when reinforcement is discontinued?

Continuous reinforcement (CRF) (Correct answer)
Variable interval (VI)
Variable ratio (VR)
Fixed ratio (FR)

Correct answer: Continuous reinforcement (CRF)

Continuous reinforcement produces the most rapid extinction because the organism quickly detects the change from 100% reinforcement to 0%, whereas intermittent schedules make extinction harder to detect.

Question 87: A BCBA is asked by a school principal to help develop a classroom-wide behavior management system. The BCBA conducts observations, analyzes the data, and designs an evidence-based intervention package that is effective in reducing problem behavior and increasing academic engagement for all students. This action primarily exemplifies which core ethical principle?

Treating Others with Compassion, Dignity, and Respect
Benefit Others (Correct answer)
Ensuring Competence
Behaving with Integrity

Correct answer: Benefit Others

The core principle of 'Benefit Others' requires behavior analysts to act in the best interest of their clients by protecting them and maximizing benefits. Designing and implementing an effective, evidence-based intervention that produces socially significant positive outcomes is a direct application of this principle. While the other principles are also important, the focus on producing meaningful, positive results for the students is the essence of beneficence.

Question 88: Which of the following is considered an indirect method of behavioral assessment?

ABC narrative recording
Scatterplot analysis
Administering a motivational assessment scale (Correct answer)
Direct observation of the target behavior in the natural environment

Correct answer: Administering a motivational assessment scale

Indirect assessments gather information about the behavior without the assessor directly observing it. This includes methods like interviews, checklists, and rating scales, such as the Motivational Assessment Scale. The other options (ABC recording, scatterplots, and direct observation) are all forms of direct descriptive assessment.

Question 89: On a fixed interval 3-minute schedule, responding typically shows a _____ pattern just before reinforcement is delivered.

Decreasing pause then rapid increase (scallop) (Correct answer)
No responding until the interval ends
Post-reinforcement pause then steady responding
Steady high rate throughout

Correct answer: Decreasing pause then rapid increase (scallop)

FI schedules produce a scallop pattern: low responding immediately after reinforcement followed by accelerating responding as the interval nears completion.

Question 90: Negative reinforcement is best described as:

A punishment procedure that decreases behavior
Adding an aversive stimulus following behavior to increase it
Withholding reinforcement to reduce a behavior
Contingent removal of an aversive stimulus that increases future responding (Correct answer)

Correct answer: Contingent removal of an aversive stimulus that increases future responding

Negative reinforcement involves the contingent removal of an aversive stimulus following a behavior, which increases the future probability of that behavior.

Question 91: A behavior analyst is reviewing a client's data for self-injurious behavior (SIB) following the implementation of a new intervention. During baseline, the rate of SIB was high and stable. After the intervention, the data path shows a clear and immediate downward direction. This change in the data path BEST describes a change in:

Variability
Reliability
Level
Trend (Correct answer)

Correct answer: Trend

Trend refers to the overall direction of the data path. A downward direction indicates a decreasing trend, which is the desired outcome for a deceleration target like SIB. While the level (average rate) also changed, the most accurate description of the 'direction' of the data path is its trend. Variability refers to the consistency of the data points, and reliability relates to the consistency of the measurement system itself.

Question 92: Which of the following is one of the four core principles outlined in the BACB's 'Ethics Code for Behavior Analysts'?

Behaving with Integrity (Correct answer)
Financial Responsibility and Billing Practices
Adherence to All Legal Regulations
Public Dissemination of Behavior Analysis

Correct answer: Behaving with Integrity

The introductory section of the 'Ethics Code for Behavior Analysts' is built upon four core principles: (1) Benefit Others, (2) Treat Others with Compassion, Dignity, and Respect, (3) Behave with Integrity, and (4) Ensure Competence. While the other options are important ethical considerations covered within the standards, they are not one of the four foundational core principles.

Question 93: A teacher can only record data for a student's on-task behavior for a brief moment at the end of a series of set intervals (e.g., every 5 minutes). Which discontinuous measurement procedure would be the most appropriate choice?

Whole Interval Recording
Event Recording
Partial Interval Recording
Momentary Time Sampling (Correct answer)

Correct answer: Momentary Time Sampling

Momentary time sampling involves recording whether a target behavior is occurring at the exact moment an interval ends. This method is well-suited for situations where an observer cannot continuously watch the learner, such as a teacher with a classroom of students.

Question 94: All of the following are limitations of the multiple baseline design except:

Verification of predicted behavior change must be inferred from other behaviors
It is weaker than the reversal design
The behavior under study must be within the subject's repertoire already (Correct answer)
It may not reveal the functional relationship, even if one exists

Correct answer: The behavior under study must be within the subject's repertoire already

Explanation: The multiple baseline design is a research method that involves observing the same behavior across multiple subjects, settings, or behaviors. It is used to determine if changes in the behavior occur after the implementation of an intervention. One of the limitations of this design is that it may not reveal the functional relationship between the intervention and the behavior change, even if one exists. This means that even if the behavior changes after the intervention, it may not be clear if the intervention caused the change or if other factors were involved. Another limitation is that the verification of predicted behavior change must be inferred from other behaviors, as direct observation may not be possible or practical. Additionally, the design is weaker than the reversal design, which allows for more conclusive evidence of causality. However, the design does not require that the behavior under study be within the subject's repertoire already, so this is not a limitation.

Question 95: A behavior analyst is monitoring the on-task behavior of a student during a 30-minute independent work period. The analyst decides to record whether the student is engaged in the assigned task for the entire 2-minute interval. Which discontinuous measurement procedure is being used?

Latency Recording
Momentary Time Sampling
Partial Interval Recording
Whole Interval Recording (Correct answer)

Correct answer: Whole Interval Recording

Whole Interval Recording is the correct procedure because the observer records an occurrence only if the target behavior happens throughout the entire duration of the interval. In this scenario, the student must be on-task for the full 2 minutes for it to be counted. Partial interval recording would mark an occurrence if the behavior happened at any point, and momentary time sampling would only record the behavior if it was occurring at the very end of the interval. Latency recording is a continuous measurement of time, not an interval-based system.

Question 96: When analyzing a line graph of a student's performance on math problems, the BCBA observes that the data points in the intervention phase are all higher than the data points in the baseline phase, with no overlapping data points between phases. This demonstrates a change in which feature of the data?

Variability
Latency
Level (Correct answer)
Trend

Correct answer: Level

Level refers to the value on the vertical axis around which a set of data points converge. A distinct change in level between the baseline and intervention phases, where all data points in one phase are higher or lower than all points in the previous phase, indicates a clear and immediate effect of the intervention.

Question 97: A BCBA is conducting an assessment to identify the skills a learner currently has and which skills are deficits, in order to create a comprehensive curriculum plan. The BCBA uses a tool that breaks down broad skill areas into specific, teachable components and measures the learner's performance against a pre-set list of criteria. This type of assessment is best described as a:

Functional Behavior Assessment (FBA)
Preference Assessment
Criterion-Referenced Skills Assessment (Correct answer)
Norm-Referenced Assessment

Correct answer: Criterion-Referenced Skills Assessment

Criterion-referenced assessments, such as the VB-MAPP or ABLLS-R, measure an individual's skills against a predetermined set of criteria or standards, rather than comparing them to the performance of others (norm-referenced). They are used to identify specific skill strengths and deficits to guide intervention planning.

Question 98: Which of the following is the primary distinction between shaping and chaining?

Chaining is used for complex behaviors, while shaping is for simple behaviors.
Shaping involves prompts, while chaining does not.
Chaining always teaches steps in a forward sequence, while shaping can teach steps in any order.
Shaping reinforces successive approximations of a single behavior, while chaining links a sequence of existing behaviors. (Correct answer)

Correct answer: Shaping reinforces successive approximations of a single behavior, while chaining links a sequence of existing behaviors.

The fundamental difference is that shaping focuses on developing a new behavior that is not yet in the learner's repertoire by reinforcing gradual approximations toward the final behavior. Chaining, on the other hand, involves teaching a sequence of individual behaviors that are already in the learner's repertoire to form a more complex skill.

Question 99: An extinction burst refers to:

A temporary increase in response rate, intensity, or variability when extinction is first implemented (Correct answer)
Complete and permanent cessation of behavior during extinction
Spontaneous recovery of behavior after a rest period
A sudden decrease in behavior when extinction begins

Correct answer: A temporary increase in response rate, intensity, or variability when extinction is first implemented

An extinction burst is a temporary increase in the frequency, duration, or intensity of behavior that typically occurs at the onset of extinction before the behavior ultimately decreases.

Question 100: Which schedule of reinforcement produces a high, steady response rate and is most resistant to extinction?

Variable ratio (Correct answer)
Variable interval
Fixed interval
Fixed ratio

Correct answer: Variable ratio

Variable ratio schedules produce the highest and most persistent rates of responding because reinforcement is unpredictable in number.

Question 101: Sean was responsible for designing an intervention for a fifth grade student who engaged in severe problem behavior consisting of throwing chairs at the teacher when an assignment was given. Sean decided to utilize a contingent physical restraint every time the child threw a chair. Sean is violating the ethical consideration of:

Right to safe and humane treatment
Least restrictive alternative (Correct answer)
Right to effective treatment
Sean is not violating any ethical considerations

Correct answer: Least restrictive alternative

Explanation: Sean is violating the ethical consideration of the least restrictive alternative. The least restrictive alternative principle states that when designing interventions, professionals should choose the intervention that is the least intrusive and restrictive while still effectively addressing the problem behavior. In this case, Sean's decision to use a contingent physical restraint as the intervention is not the least restrictive alternative. There may be other interventions or strategies that could be tried before resorting to physical restraint, such as functional behavior assessment, positive behavior support, or teaching alternative coping skills.

Question 102: When a student labels a picture of a dog as 'dog' with no other prompts, this is an example of which verbal operant?

Echoic
Intraverbal
Mand
Tact (Correct answer)

Correct answer: Tact

A tact is a verbal operant evoked by a nonverbal discriminative stimulus (the picture) and maintained by generalized conditioned reinforcement.

Question 103: The Premack Principle states that:

Organisms always prefer variable schedules over fixed schedules
Behavior is solely controlled by its immediate antecedents
Any neutral stimulus becomes a reinforcer through repeated pairing with existing reinforcers
A high-probability behavior can reinforce a low-probability behavior (Correct answer)

Correct answer: A high-probability behavior can reinforce a low-probability behavior

The Premack Principle (often called 'Grandma's Law') states that access to a higher-frequency preferred behavior can serve as a reinforcer for a lower-frequency less-preferred behavior.

Question 104: A BCBA is providing feedback to a supervisee on their session notes. Which statement represents the MOST effective, behavior-analytic feedback?

"I noticed in today's note you described the client's behavior as 'frustrated.' Instead, describe the observable actions, such as 'he dropped his pencil and sighed loudly.'" (Correct answer)
"Your notes are okay, but you need to be more professional."
"You consistently forget to include the start and end times. Why do you keep making that mistake?"
"You did a great job today! Keep up the good work."

Correct answer: "I noticed in today's note you described the client's behavior as 'frustrated.' Instead, describe the observable actions, such as 'he dropped his pencil and sighed loudly.'"

Effective performance feedback in behavior analysis should be objective, specific, and focused on behavior. This answer avoids subjective terms like "good" or "professional" and instead identifies a specific, non-observable description ("frustrated") and provides a clear, observable, and measurable alternative ("dropped his pencil and sighed loudly").

Question 105: When using behavioral momentum, behaviors selected for a high-p request sequence should:

Have a very long duration of occurrence
Be new behavior(s) the learner has to acquire
Be part of the learner's current repertoire (Correct answer)
Be those behaviors with which the learner is not complaint

Correct answer: Be part of the learner's current repertoire

Explanation: When using behavioral momentum, behaviors selected for a high-p request sequence should be part of the learner's current repertoire. This means that the learner should already be familiar with and capable of performing these behaviors. By selecting behaviors that the learner is already proficient in, it increases the likelihood of success and reinforces the learner's confidence and motivation. Introducing new behaviors or behaviors that the learner is not familiar with may lead to frustration and decrease the effectiveness of the high-p request sequence.

Question 106: The primary reason one might consider using a level system with a token system is that:

Doing so makes it easier to withdraw the token economy
Level systems are easier to manage
Level systems are more preferred for all learners
Doing so can foster self-management (Correct answer)

Correct answer: Doing so can foster self-management

Explanation: Using a level system with a token system can foster self-management because it allows individuals to earn tokens based on their behavior and progress. As they accumulate tokens and move up levels, they are motivated to continue exhibiting positive behaviors and making progress. This system promotes autonomy and responsibility as individuals learn to manage their own behavior and strive to reach higher levels. It provides a sense of achievement and control, ultimately leading to self-management skills.

Question 107: For which of the following situations would partial interval recording be the most appropriate measurement procedure?

To record if a student was on-task for an entire 5-minute period.
To measure the total time a student spends engaged in a task.
To determine if a behavior occurred at any point during an interval for a behavior targeted for reduction. (Correct answer)
To get an exact count of the number of times a student raises their hand.

Correct answer: To determine if a behavior occurred at any point during an interval for a behavior targeted for reduction.

Partial Interval Recording (PIR) is used to record whether a behavior occurred at any time during a predefined interval. Because it only requires one instance of the behavior to be recorded for the entire interval, it often overestimates the overall duration/rate of the behavior. This makes it particularly useful for behaviors targeted for reduction, as even a slight overestimation will be sensitive to any occurrence, ensuring it doesn't go unrecorded. The other options are better measured by duration recording, whole interval recording, and frequency/event recording, respectively.

Question 108: A BCBA is reviewing a student's records, interviewing their teacher and parents, and having them complete behavior rating scales. The primary goal of this phase of assessment is to:

conduct a comprehensive skills assessment.
select a socially valid replacement behavior.
develop a formal hypothesis about the function of the behavior. (Correct answer)
demonstrate a functional relation between the environment and behavior.

Correct answer: develop a formal hypothesis about the function of the behavior.

Indirect assessment methods like record reviews, interviews, and rating scales are used to gather broad information and formulate a hypothesis about the function of a target behavior. This hypothesis can then be tested through more direct methods like descriptive assessment or functional analysis.

Question 109: A behavior analyst needs to quickly identify a hierarchy of preferred items for a student who can make choices from a large array of items but becomes frustrated when preferred items are removed. Which preference assessment method would be MOST appropriate for this situation?

Paired-Stimulus Assessment
Multiple Stimulus with Replacement (MSW) (Correct answer)
Multiple Stimulus Without Replacement (MSWO)
Single-Stimulus Assessment

Correct answer: Multiple Stimulus with Replacement (MSW)

The Multiple Stimulus with Replacement (MSW) assessment is most appropriate here. In an MSW, the learner chooses an item from an array, interacts with it briefly, and then that chosen item is returned to the array for the next trial. This method allows for the identification of a highly preferred item without repeatedly taking it away, which is ideal for a learner who exhibits problem behavior upon removal of preferred items. MSWO involves removing the item, which could trigger the problem behavior.

Question 110: A behavior analyst is working with a student to increase the time they spend engaged in on-task behavior. The analyst decides to use an experimental design where the criterion for reinforcement is systematically increased as the student demonstrates stable performance at each level. For example, the student first earns reinforcement for 5 minutes of on-task behavior, then 10 minutes, then 15 minutes. Which experimental design is the analyst using?

Multiple baseline design
Changing criterion design (Correct answer)
Reversal (A-B-A-B) design
Alternating treatments design

Correct answer: Changing criterion design

The changing criterion design is the correct answer because it involves evaluating the effect of an intervention by systematically and incrementally changing the criterion for reinforcement in a step-wise fashion. Experimental control is demonstrated when the participant's behavior closely tracks the changes in the criterion.

Question 111: A BCBA is asked by a local news station to comment on a new fad therapy for autism that lacks empirical support. In their public statement, the BCBA has an ethical responsibility to:

promote their own private practice as a better alternative.
decline to comment to avoid public controversy.
state that all non-behavioral therapies are ineffective and potentially harmful.
provide statements based on current scientific knowledge and behavior-analytic principles, while avoiding unsubstantiated claims. (Correct answer)

Correct answer: provide statements based on current scientific knowledge and behavior-analytic principles, while avoiding unsubstantiated claims.

Section 5 of the Ethics Code, 'Responsibility in Public Statements,' requires that behavior analysts' statements are based on their conceptually consistent, behavior-analytic knowledge and that they do not make false, deceptive, or exaggerated claims. They must differentiate between what is based on scientific evidence and what is personal opinion. Promoting one's own practice or making sweeping generalizations without evidence would be unethical.

Question 112: An establishing operation (EO) is a motivating operation that:

Has no effect on reinforcer value but changes response form
Decreases the reinforcing value of a stimulus and decreases behavior that produces it
Increases the reinforcing effectiveness of a stimulus and increases behavior that has produced it (Correct answer)
Only affects punisher effectiveness, not reinforcer value

Correct answer: Increases the reinforcing effectiveness of a stimulus and increases behavior that has produced it

An establishing operation increases the current reinforcing effectiveness of a stimulus and simultaneously increases the frequency of behaviors that have previously been reinforced by that stimulus.

Question 113: When collecting, storing, and sharing confidential client information, a behavior analyst's primary ethical obligation is to:

ensure the information is easily accessible to all team members, including administrative staff.
protect confidentiality by limiting access to information and using secure methods for storage and transmission. (Correct answer)
use a cloud-based storage system that is the most affordable for the company.
share detailed progress with funders to guarantee continued authorization of services.

Correct answer: protect confidentiality by limiting access to information and using secure methods for storage and transmission.

The BACB Ethics Code (Standard 2.11) places a high priority on protecting the confidentiality of clients. This involves taking reasonable precautions to secure records, whether electronic or physical, limiting access only to those with a professional need-to-know, and using secure means (like encryption) when transmitting information. While accessibility, cost, and funding are practical considerations, they are secondary to the primary ethical duty of protecting client confidentiality.

Question 114: A behavior analyst uses a visual schedule to reduce transition-related problem behavior. This is best described as a(n):

Consequence-based intervention
Differential reinforcement procedure
Antecedent-based intervention (Correct answer)
Punishment procedure

Correct answer: Antecedent-based intervention

Visual schedules are antecedent arrangements that modify the environment before problem behavior occurs to reduce its likelihood.

Question 115: According to the Ethics Code for Behavior Analysts, under which of the following conditions is it ethical to discontinue services?

The behavior analyst feels they are no longer a good match for the client's personality.
The behavior analyst is offered a higher-paying position with another company.
The client has shown slow but steady progress toward some goals.
The stakeholders are not complying with the intervention plan despite efforts to address barriers. (Correct answer)

Correct answer: The stakeholders are not complying with the intervention plan despite efforts to address barriers.

The BACB's 'Ethics Code for Behavior Analysts' (Code 3.15) explicitly states that services can be discontinued if 'relevant stakeholders are not complying with the behavior-change intervention despite appropriate efforts to address barriers.' The other options do not represent ethically permissible reasons for discontinuation. Slow progress may require a modification of the plan, not termination. Personal feelings or better job offers are not client-centered reasons for ending services.

Question 116: To decrease a client's hitting behavior, a behavior analyst decides to use partial interval recording with 10-second intervals. Data show the behavior occurred in 80% of intervals during baseline. After intervention, the data show the behavior occurred in 20% of intervals. Why might this measurement system be a concern?

It likely overestimates the occurrence of the behavior. (Correct answer)
It provides a direct measure of the behavior's frequency.
It likely underestimates the actual duration of the behavior.
It is too complex for staff to implement with fidelity.

Correct answer: It likely overestimates the occurrence of the behavior.

Partial interval recording records an occurrence if the behavior happens at any point during the interval. This method is known to overestimate the overall duration or rate of a behavior because even a brief instance within an interval results in the entire interval being scored as an occurrence. This can be misleading, especially when trying to determine the true reduction of a behavior.

Question 117: Functional Communication Training (FCT) replaces problem behavior by teaching a communicative response that:

Is reinforced on a leaner schedule than problem behavior
Is punished on the same schedule as problem behavior
Accesses the same reinforcer as the problem behavior (Correct answer)
Requires more effort than problem behavior

Correct answer: Accesses the same reinforcer as the problem behavior

FCT is effective because the alternative communicative response produces the same reinforcer that was maintaining the problem behavior, making the new response equally or more efficient.

Question 118: Response blocking is best described as a(n) _____ procedure that prevents problem behavior from producing its reinforcer.

Punishment-based
Antecedent-only
Token economy
Extinction-based (Correct answer)

Correct answer: Extinction-based

Response blocking physically prevents the behavior from occurring or contacting its reinforcer, and is therefore classified as an extinction-based procedure (the behavior is not reinforced).

Question 119: Spontaneous recovery refers to:

The reappearance of an extinguished behavior after a period of time without extinction sessions (Correct answer)
Generalization of new behavior to untrained settings
Rapid recovery of skills after a long absence from training
Behavior returning to baseline after a treatment reversal

Correct answer: The reappearance of an extinguished behavior after a period of time without extinction sessions

Spontaneous recovery is the re-emergence of a previously extinguished response following a period of rest, even without any additional reinforcement.

Question 120: Carr and Lovaas (1983) recommended that practitioners experience any punisher personally before the treatment begins for what reason?

It reminds the practitioner that it is a sadistic procedure
It reminds the practitioner that the technique is designed to increase the appropriate behavior of the student
It reminds the practitioner that the technique produces physical discomfort (Correct answer)
It allows the practitioner to determine a baseline of discomfort which he/she then increases rapidly as it is administered to the student

Correct answer: It reminds the practitioner that the technique produces physical discomfort

Explanation: The reason Carr and Lovaas (1983) recommended that practitioners experience any punisher personally before the treatment begins is to remind them that the technique produces physical discomfort. By experiencing it themselves, practitioners can better understand the potential impact on the student and ensure that they are using the technique appropriately and ethically. This firsthand experience serves as a reminder of the potential consequences and helps practitioners make informed decisions about its use.

Question 121: The ____________ design consists of an initial baseline phase followed by an intervention phase followed by a return to baseline.

Reversal design
Withdrawal design
A-B-A
All of the above (Correct answer)

Correct answer: All of the above

Explanation: This is because all three terms - A-B-A design, Reversal design, and Withdrawal design - refer to the same research design that involves an initial baseline phase, followed by an intervention phase, and then a return to baseline. These terms are used interchangeably to describe this type of experimental design.

Question 122: A BCBA with extensive experience in early intensive behavioral intervention for autism is asked by a friend to provide services for the friend's elderly parent, who has dementia and engages in aggressive behavior. The BCBA has never worked with geriatric populations. What is the most ethical course of action?

Agree to take the case but under the direct supervision of a medical doctor.
Accept the case, as the principles of behavior analysis are universal.
Agree to take the case after completing a weekend workshop on behavior analysis in dementia care.
Decline to provide services directly and refer the friend to a behavior analyst with documented experience and competence in gerontology. (Correct answer)

Correct answer: Decline to provide services directly and refer the friend to a behavior analyst with documented experience and competence in gerontology.

The BACB Ethics Code requires behavior analysts to practice only within their boundaries of competence, which is determined by their education, training, and supervised experience. Working with a new population, such as geriatric clients with dementia, is outside the BCBA's current scope of competence. The most ethical response is to decline the case and provide a referral to a qualified professional.

Question 123: The principle of ________ determines the degree to which a person's behavior repertoire maximizes short and long-term reinforcers for that individual and for others and minimizes short and long-term punishers.

Normalization
Functionality
Justification
Habilitation (Correct answer)

Correct answer: Habilitation

Explanation: Habilitation refers to the process of helping individuals with disabilities or impairments develop skills and abilities to function effectively in their environment. The principle of habilitation focuses on maximizing positive reinforcement and minimizing punishment to promote positive behaviors and outcomes for both the individual and others. It involves identifying and implementing strategies that enhance the individual's behavior repertoire and promote their overall well-being and success in the short and long term.

Question 124: A textual response—reading written words aloud—is controlled by which type of antecedent?

Written verbal stimulus (Correct answer)
Vocal verbal stimulus
Motivating operation
Nonverbal environmental stimulus

Correct answer: Written verbal stimulus

Textual behavior is a verbal operant in which a written or printed verbal stimulus controls a vocal or written response with point-to-point correspondence.

Question 125: A BCBA implements a treatment package consisting of a token economy, prompting, and social praise to increase a student's completion of math assignments. The student's performance improves significantly. The BCBA now wants to determine how much social praise is necessary to maintain the behavior. Which type of analysis should be conducted?

Parametric Analysis (Correct answer)
Correlational Analysis
Comparative Analysis
Component Analysis

Correct answer: Parametric Analysis

A parametric analysis is used to determine the effective range or 'dosage' of a single independent variable. [3, 4] In this scenario, the BCBA has an effective treatment package and wants to specifically evaluate how different amounts or levels of one component (social praise) affect the target behavior. [1, 11]

Question 126: When extinction is implemented for attention-maintained behavior, the behavior analyst should ensure that:

All sources of attention are withheld consistently across all people and settings (Correct answer)
Punishment is also applied to suppress the extinction burst
The learner is informed in advance each time extinction will be applied
A leaner reinforcement schedule is used for replacement behavior

Correct answer: All sources of attention are withheld consistently across all people and settings

Extinction must be implemented consistently so that problem behavior does not contact intermittent reinforcement, which would increase resistance to extinction.

Question 127: Which function of problem behavior is identified when the behavior increases following the removal of an aversive task?

Access to tangibles
Attention
Escape/avoidance (Correct answer)
Automatic reinforcement

Correct answer: Escape/avoidance

When problem behavior is negatively reinforced by removal of an aversive stimulus (e.g., a task), the function is escape or avoidance.

Question 128: Which verbal operant involves repeating the exact vocal behavior just modeled by another speaker?

Mand
Intraverbal
Echoic (Correct answer)
Tact

Correct answer: Echoic

An echoic is a verbal operant under the control of a vocal verbal stimulus that has formal similarity (sounds like the model) and point-to-point correspondence.

Question 129: Which procedure involves gradually removing prompts across trials to transfer stimulus control to natural cues?

Stimulus fading (Correct answer)
Chaining
Shaping
Prompt delay

Correct answer: Stimulus fading

Stimulus fading systematically removes or dims artificial prompts so that the natural discriminative stimulus gains full control over the response.

Question 130: An agency assigns a newly certified BCBA a caseload of 25 clients, each requiring individualized program monitoring and frequent supervision of technicians. The BCBA feels overwhelmed and is unable to provide effective oversight for each case. This situation primarily represents a conflict with which professional and ethical principle?

Dual relationships and conflicts of interest.
Confidentiality and maintaining records.
Boundaries of competence and providing effective treatment. (Correct answer)
Responsibility in public statements.

Correct answer: Boundaries of competence and providing effective treatment.

The BACB Ethics Code requires behavior analysts to provide effective treatment and operate within their boundaries of competence. An unmanageably large caseload prevents the BCBA from dedicating the necessary time and resources to each client for proper assessment, program development, data analysis, and supervision, thus compromising their ability to provide effective treatment.

Question 131: A teacher uses the same materials in many different rooms to teach a child to identify colors. This strategy exemplifies:

Stimulus fading
Multiple exemplar training
Errorless learning
Generalization programming via common stimuli (Correct answer)

Correct answer: Generalization programming via common stimuli

Programming common stimuli brings elements of the natural environment into training so that control transfers to those stimuli outside the training setting.

Question 132: An intraverbal is maintained by which type of reinforcement?

Automatic sensory reinforcement
Tangible reinforcement only
Generalized conditioned reinforcement (Correct answer)
Specific item delivery related to the antecedent verbal stimulus

Correct answer: Generalized conditioned reinforcement

Intraverbals, like tacts, are maintained by generalized conditioned reinforcers such as attention or praise, not by specific reinforcers related to the verbal antecedent.

Question 133: Multiple exemplar training is primarily used to promote which behavioral outcome?

Increased response rate
Generalization across settings and stimuli (Correct answer)
Stimulus discrimination
Extinction burst prevention

Correct answer: Generalization across settings and stimuli

Training with multiple exemplars exposes learners to varied instances so the skill transfers to untrained stimuli and settings.

Question 134: Providing frequent, noncontingent breaks to a student whose problem behavior is maintained by escape from tasks would likely reduce that behavior because it functions as:

Positive reinforcement of an alternative behavior
An abolishing operation that reduces the reinforcing value of escape (Correct answer)
A DRO schedule that reinforces the absence of problem behavior
Punishment that decreases motivation to escape

Correct answer: An abolishing operation that reduces the reinforcing value of escape

Noncontingent breaks act as an abolishing operation by satiation of the escape function, reducing the reinforcing value of escape and thereby decreasing the motivation for escape-maintained problem behavior.

Question 135: A teacher delivers a preferred snack every 5 minutes regardless of what the student is doing to reduce aggressive behavior. This procedure is:

DRI
DRO
NCR (Correct answer)
FCT

Correct answer: NCR

Non-contingent reinforcement (NCR) delivers a reinforcer on a fixed-time or variable-time schedule independent of the occurrence of any specific behavior.

Question 136: A BCBA is closing their private practice and transitioning all clients to other providers. According to the BACB Ethics Code, what is the BCBA's responsibility regarding the maintenance of client records?

All records must be destroyed within 30 days of service termination to protect client confidentiality.
All original records must be transferred to the new provider, and the BCBA should not retain any copies.
The BCBA must maintain and dispose of records in a way that protects confidentiality and complies with laws, generally for a minimum of 7 years. (Correct answer)
The client's family should be given the option to take possession of all records, relieving the BCBA of further responsibility.

Correct answer: The BCBA must maintain and dispose of records in a way that protects confidentiality and complies with laws, generally for a minimum of 7 years.

The BACB Ethics Code requires behavior analysts to retain and dispose of client records in a manner that protects confidentiality and is in accordance with all applicable laws and regulations. The code specifies that records must be maintained for at least 7 years, and sometimes longer if other laws require it.

Question 137: A BCBA is reviewing the results of a functional analysis (FA) conducted to determine the function of a student's disruptive vocalizations. The data show high rates of the behavior in the 'attention' and 'demand' conditions, moderate rates in the 'tangible' condition, and near-zero rates in the 'alone' and 'play' (control) conditions. What can be concluded from these results?

The behavior is maintained solely by automatic reinforcement.
The behavior is maintained by multiple functions, specifically escape and attention. (Correct answer)
The assessment was inconclusive and needs to be repeated with different conditions.
The behavior is exclusively maintained by access to tangible items.

Correct answer: The behavior is maintained by multiple functions, specifically escape and attention.

A functional analysis systematically manipulates environmental conditions to identify the function of a behavior. When a behavior occurs at high rates in more than one test condition compared to the control condition (play), it indicates that the behavior is maintained by multiple functions. In this scenario, the elevated rates in both the attention and demand (escape) conditions strongly suggest the behavior serves both to gain attention and to escape from non-preferred tasks.

Question 138: Motivating operations and discriminative stimuli:

Have similar evocative effects on behavior (Correct answer)
All of these
Are considered synonymous
Occur after the behavior of interest

Correct answer: Have similar evocative effects on behavior

Explanation: Motivating operations and discriminative stimuli have similar evocative effects on behavior. This means that both of these factors can influence and elicit certain behaviors. Motivating operations refer to events or conditions that alter the value of a reinforcer and therefore affect the likelihood of a behavior occurring. Discriminative stimuli, on the other hand, are cues or signals in the environment that indicate the availability of reinforcement for a particular behavior. Both motivating operations and discriminative stimuli can evoke or prompt specific behaviors in individuals.

Question 139: An abolishing operation (AO) is best described as:

A consequence that eliminates conditioned reinforcers permanently
A motivating operation that increases reinforcer effectiveness
An extinction procedure applied specifically to escape-maintained behavior
A motivating operation that decreases the reinforcing value of a stimulus and decreases relevant behavior (Correct answer)

Correct answer: A motivating operation that decreases the reinforcing value of a stimulus and decreases relevant behavior

An abolishing operation decreases the reinforcing effectiveness of a stimulus and decreases the current frequency of behavior that has been reinforced by that stimulus.
