RBT Practice Test 3 — Questions and Answers

Question 1: ___________________ is the most commonly used graph in ABA.

Line Graph (Correct answer)
Cumulative Graph
Pie Graph
Bar Graph

Correct answer: Line Graph

Line graphs are the most commonly used type of graph in Applied Behavior Analysis (ABA) because they effectively display changes in behavior over time. They allow for easy visualization of trends, variability, and level changes in data, which are crucial for monitoring progress and making data-driven decisions about interventions. Each data point is connected, showing the progression of behavior.

Question 2: __________________ is factual information that is utilized as a foundation for reasoning, discussion, or calculation.

Measurement Procedures
Measurement
Data (Correct answer)
None of the above

Correct answer: Data

Data refers to the factual information, typically numerical or qualitative, collected through observation or measurement. In ABA, data serves as the objective foundation for understanding behavior, evaluating intervention effectiveness, and making informed decisions. It allows behavior analysts to move beyond subjective impressions and rely on empirical evidence for their practices.

Question 3: Thomas observed 7 occurrences of clapping during the length of a five-hour session. What method of measuring was used?

Duration
Latency
Frequency (Correct answer)
Count

Correct answer: Frequency

Frequency is a basic measure in ABA that involves counting the number of times a specific behavior occurs within a defined observation period. In this scenario, Thomas recorded 7 occurrences of clapping, and the observation period was a five-hour session. This combination of a count and a time component directly aligns with the definition of frequency measurement.

Question 4: Identify the data collection described: Sam observed 10 hiccups from her sister.

Latency
Count (Correct answer)
Rate
Duration

Correct answer: Count

Count, also known as tally, is a direct measure of behavior that simply involves recording the number of times a behavior occurs. Sam observed 10 hiccups, which is a straightforward enumeration of discrete behaviors without reference to a specific time period or duration. Therefore, 'Count' accurately describes this data collection method.

Question 5: What does a graph's trend represent?

The vertical representation of the average data values (Correct answer)
A visual representation of data consistency
The data path's total direction
None of the above

Correct answer: The vertical representation of the average data values

A graph's trend represents the overall direction of the data path over time, indicating whether the behavior is increasing, decreasing, or stable. While often visualized with a trend line, this line essentially shows how the average level of the behavior (represented vertically on the y-axis) changes across the observation period. Thus, it provides a visual representation of the average data values' movement over time.

Question 6: You are recording the time of how long it takes from the demand (Sd) is presented to the first instance of behavior. What exactly are you measuring?

Inter-response time
Frequency
Rate
Latency (Correct answer)

Correct answer: Latency

Latency is a dimension of behavior that measures the time elapsed between the presentation of a stimulus (such as a demand or Sd) and the initiation of the response. The question specifically asks about recording the time from when the demand is presented to the *first instance* of the behavior, which is the precise definition of latency.

Question 7: Jenny is gathering data about screaming. She has a timer. She specifies whether David was screaming for the full interval or not each time the timer goes off. What type of data is she taking?

Partial interval
Momentary time sampling
Whole interval (Correct answer)
None of the above

Correct answer: Whole interval

Whole interval recording is a discontinuous measurement method where a behavior is recorded as occurring only if it happens continuously throughout the *entire* specified interval. Jenny's method of checking if David was screaming for the 'full interval' aligns perfectly with this definition. This method typically underestimates the actual occurrence of behavior.

Question 8: You give a learner two things and tell him to "get one." You repeat this process until all of the things have been paired together. What type of assessment are you conducting?

Paired choice (Correct answer)
MSWO
Multiple stimulus with replacement
Free operant

Correct answer: Paired choice

A paired choice preference assessment involves presenting two items or activities simultaneously and asking the individual to choose one. This process is systematically repeated with all possible pairs of stimuli to establish a hierarchy of preferences. The description of giving a learner two things and telling them to 'get one,' then repeating until all things are paired, directly describes this method.

Question 9: Every 20 seconds that Ruby does not participate in the target behavior, you give her attention. What is this intervention?

Differential reinforcement of incompatible behavior
Differential reinforcement of other behaviors (Correct answer)
Differential reinforcement of alternative behavior
None of the above

Correct answer: Differential reinforcement of other behaviors

Differential Reinforcement of Other Behaviors (DRO) is an intervention where reinforcement is delivered when a specific target behavior has *not* occurred for a predetermined period. By giving Ruby attention every 20 seconds that she does not engage in the target behavior, the intervention reinforces the absence of that behavior, which is the core principle of DRO.

Question 10: Josh engages in problem behavior that is reinforced by the attention of his peers. His instructor sends him away from his peers, who are more likely to laugh at him while he is off-task. What exactly is this intervention?

Antecedent intervention (Correct answer)
Consequence intervention
Stimulus intervention
Response intervention

Correct answer: Antecedent intervention

Antecedent interventions are strategies implemented *before* a behavior occurs to prevent it or reduce its likelihood. In this scenario, sending Josh away from his peers, who reinforce his problem behavior, is an attempt to modify the environment by removing the antecedent (the presence of reinforcing peers) that makes the problem behavior likely to occur and be maintained. This proactive alteration of the environment to prevent the problem behavior from being reinforced makes it an antecedent intervention.

Question 11: What type of prompts are hand over hand, gestural, and partial physical?

Response prompts (Correct answer)
Stimulus prompts
Both
None of the above

Correct answer: Response prompts

Response prompts are cues or assistance provided directly to the learner's response to help them emit the correct behavior. Hand-over-hand (full physical), gestural, and partial physical prompts all involve directly guiding or indicating the correct action, thus operating on the response itself. They are distinct from stimulus prompts, which alter the discriminative stimulus.

Question 12: Washing hands, brushing teeth and making a sandwich might all be taught in this way.

Momentary time sampling
Discrete trial training
With an FR-3 schedule.
Task analysis (Correct answer)

Correct answer: Task analysis

Task analysis is a process of breaking down a complex skill or chain of behaviors into smaller, sequential, and teachable steps. Skills like washing hands, brushing teeth, and making a sandwich are multi-step activities that are effectively taught by first dissecting them into their component parts, which is the essence of task analysis.

Question 13: You provide a preferred edible on every third accurate response. What kind of reinforcement schedule is this?

VI-3
FR-3 (Correct answer)
FI-3
VR-3

Correct answer: FR-3

A Fixed Ratio (FR) schedule of reinforcement delivers reinforcement after a fixed, predictable number of responses. 'FR-3' specifically means that the learner receives reinforcement (a preferred edible) after every third accurate response. This constant ratio makes it a fixed ratio schedule.

Question 14: Your BCBA will make decisions based on the ______________ you gathered as an RBT.

Tweets
Text messages
Data (Correct answer)
Writings

Correct answer: Data

As an RBT, collecting accurate and reliable data on client behavior is a primary responsibility. This data serves as the foundation for the BCBA's clinical decision-making, allowing them to analyze progress, identify patterns, and make informed adjustments to the client's treatment plan. Without objective data, effective behavior analytic services cannot be provided.

Question 15: For ____________ % of the time each month that you perform behavior analytic services, you will be supervised by a BCBA or BCaBA.

3
15
20
5 (Correct answer)

Correct answer: 5

The Behavior Analyst Certification Board (BACB) mandates that Registered Behavior Technicians (RBTs) receive supervision for at least 5% of the hours they spend providing behavior analytic services each month. This supervision ensures ongoing competency, adherence to ethical guidelines, and quality of service delivery.

Question 16: The accuracy of your data will be checked during an observation by your BCBA/BCaBA supervisor. _________________ check is what it's called.

Inter-observer agreement (Correct answer)
Data consistency
Accurate data collection
On the same page

Correct answer: Inter-observer agreement

Inter-observer agreement (IOA) is a measure used to assess the reliability and accuracy of data collection by comparing the data recorded by two or more independent observers. When a BCBA/BCaBA supervisor checks an RBT's data during an observation, they are typically calculating IOA to ensure the RBT's data collection is consistent and trustworthy.
