BCAT Skill Acquisition Treatment — Questions and Answers

Question 1: In forward chaining, which step does the learner complete first?

The last step in the task analysis
The first step in the task analysis (Correct answer)
The easiest step regardless of order
A randomly selected step chosen by the technician

Correct answer: The first step in the task analysis

Forward chaining teaches the first step in the task analysis first, then adds subsequent steps sequentially.

Question 2: A technician completes all steps of a task for the learner except the final step, which the learner performs independently. This is an example of:

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

Correct answer: Backward chaining

Backward chaining teaches the last step first, with the trainer completing all preceding steps so the learner always finishes the task.

Question 3: Which prompt fading strategy begins with the most intrusive prompt and gradually reduces assistance?

Least-to-most prompting
Most-to-least prompting (Correct answer)
Time delay prompting
Graduated guidance

Correct answer: Most-to-least prompting

Most-to-least prompting starts with the highest level of support and systematically fades to less intrusive prompts as the learner gains independence.

Question 4: Generalization is considered successful when a learner can perform a skill with:

Only the original therapist who taught the skill
The same materials used during training only
Novel people, settings, and materials not used in training (Correct answer)
Exactly the same instructions used during teaching

Correct answer: Novel people, settings, and materials not used in training

Generalization means the skill transfers across different people, settings, and materials beyond those used in the original training.

Question 5: When a learner correctly identifies a dog from a cat when both are presented together, this demonstrates:

Stimulus generalization
Stimulus discrimination (Correct answer)
Response generalization
Behavioral momentum

Correct answer: Stimulus discrimination

Stimulus discrimination occurs when the learner responds differently to two distinct stimuli, selecting the correct one.

Question 6: Distributed practice in skill acquisition involves:

Running all trials of one skill before moving to another
Alternating between different skills or targets across teaching opportunities (Correct answer)
Teaching in only one location per session
Using the same prompt level for every trial

Correct answer: Alternating between different skills or targets across teaching opportunities

Distributed practice spaces trials across multiple skills or timeframes, which often promotes better retention than massed practice.

Question 7: A task analysis for handwashing breaks the skill into 12 individual steps. What is the primary purpose of this breakdown?

To make data collection faster
To identify which steps to skip during busy sessions
To teach complex skills by targeting each component behavior (Correct answer)
To allow different technicians to teach different parts of the skill

Correct answer: To teach complex skills by targeting each component behavior

A task analysis breaks a complex skill into discrete, teachable steps so each component can be systematically trained and reinforced.

Question 8: Errorless learning is best described as:

Allowing the learner to make errors so they can self-correct
Providing prompts that prevent errors before they occur (Correct answer)
Correcting every error with a verbal reprimand
Ignoring errors to avoid embarrassing the learner

Correct answer: Providing prompts that prevent errors before they occur

Errorless learning involves delivering prompts proactively to prevent incorrect responses, reducing frustration and increasing success.

Question 9: A transfer trial is used to:

Move a learner from one program to another
Shift stimulus control from a prompt to the natural discriminative stimulus (Correct answer)
Train a skill in a new environment immediately
Reduce the number of reinforcers given during a session

Correct answer: Shift stimulus control from a prompt to the natural discriminative stimulus

Transfer trials follow a prompted trial and present the same SD without the prompt, transferring control to the natural cue.

Question 10: Natural Environment Teaching (NET) differs from Discrete Trial Training (DTT) primarily because NET:

Uses no reinforcement
Is only used with verbal learners
Embeds teaching within naturally occurring activities and the learner's motivation (Correct answer)
Requires a structured table-top setting

Correct answer: Embeds teaching within naturally occurring activities and the learner's motivation

NET capitalizes on the learner's natural motivation and daily activities to provide embedded teaching opportunities in context.

Question 11: During incidental teaching, the technician waits for the learner to initiate interest in something, then requires a more elaborate response before providing access. This technique primarily targets:

Compliance and sitting behavior
Spontaneous language and communication (Correct answer)
Gross motor imitation
Self-care routines

Correct answer: Spontaneous language and communication

Incidental teaching leverages child-initiated interactions to build spontaneous language and functional communication.

Question 12: Shaping involves reinforcing:

Only the final, perfect form of a behavior from the start
Successive approximations that increasingly resemble the target behavior (Correct answer)
Any behavior emitted during the session
The absence of undesirable behaviors only

Correct answer: Successive approximations that increasingly resemble the target behavior

Shaping reinforces closer and closer approximations to the goal behavior, gradually building the full target response.

Question 13: A technician waits 5 seconds after presenting an SD before delivering a prompt. This procedure is called:

Simultaneous prompting
Constant time delay (Correct answer)
Progressive time delay
Zero-second time delay

Correct answer: Constant time delay

Constant time delay uses a fixed waiting period (e.g., 5 seconds) before prompting, giving the learner a consistent opportunity to respond independently.

Question 14: Which reinforcement schedule is most appropriate when initially teaching a new skill to a learner with autism?

Variable ratio schedule
Fixed interval schedule
Continuous reinforcement (CRF) (Correct answer)
Thin variable interval schedule

Correct answer: Continuous reinforcement (CRF)

Continuous reinforcement provides a reinforcer after every correct response, which is most effective for teaching new skills and establishing behavior.

Question 15: In a standard Discrete Trial Training (DTT) session, what is the correct sequence of components?

Reinforcement → SD → Prompt → Response
SD → Prompt → Response → Consequence → Inter-trial interval (Correct answer)
Response → SD → Consequence → Prompt
Inter-trial interval → Consequence → SD → Response

Correct answer: SD → Prompt → Response → Consequence → Inter-trial interval

DTT follows the sequence: discriminative stimulus (SD), optional prompt, learner response, consequence (reinforcement or error correction), and inter-trial interval.

Question 16: Total task chaining differs from forward and backward chaining because:

Only the first step is reinforced
The learner attempts every step in the sequence during each teaching opportunity (Correct answer)
The trainer completes all but one step
Steps are taught in random order

Correct answer: The learner attempts every step in the sequence during each teaching opportunity

Total task chaining has the learner practice all steps of the task analysis on every trial, with prompts provided only where needed.

Question 17: Interspersal training (or 'maintenance trials') in a skill acquisition session involves:

Teaching only new targets in every session
Mixing mastered easy tasks with new harder targets to maintain fluency and motivation (Correct answer)
Presenting all new targets at once without mastered items
Skipping reinforcement for mastered tasks

Correct answer: Mixing mastered easy tasks with new harder targets to maintain fluency and motivation

Interspersal training embeds already-mastered ('easy') tasks among new acquisition targets to sustain momentum and provide frequent reinforcement opportunities.

Question 18: A skill is considered 'mastered' for maintenance purposes when:

The learner answers correctly once without a prompt
The learner meets a predetermined criterion (e.g., 80% across 3 sessions) and performance is maintained over time (Correct answer)
The technician feels the learner knows the skill
The skill appears on generalization probes only

Correct answer: The learner meets a predetermined criterion (e.g., 80% across 3 sessions) and performance is maintained over time

Mastery requires meeting a pre-set criterion consistently across multiple sessions, and maintenance checks confirm the skill is retained over time.

Question 19: Graduated guidance is a prompting strategy that involves:

Using only verbal prompts faded over time
Physical guidance that is adjusted hand-over-hand and faded based on the learner's moment-to-moment performance (Correct answer)
Giving a fixed prompt on every trial regardless of learner response
Providing gestural prompts only

Correct answer: Physical guidance that is adjusted hand-over-hand and faded based on the learner's moment-to-moment performance

Graduated guidance uses physical guidance that is dynamically faded or increased in real time based on how much assistance the learner needs each moment.

Question 20: Which data collection method is most appropriate for tracking accuracy across discrete trials in a skill acquisition program?

Duration recording
Frequency recording of problem behavior
Percent correct per session (Correct answer)
Latency recording

Correct answer: Percent correct per session

Percent correct (number of correct responses divided by total trials × 100) is the standard metric for monitoring skill acquisition progress across DTT trials.

Question 21: During a skill acquisition session, a learner gives an incorrect response. The recommended error correction procedure typically involves:

Ending the trial and moving on without feedback
Providing a full prompt to produce the correct response, then re-presenting the SD (Correct answer)
Giving a time-out for every error
Reducing the reinforcer magnitude after every error

Correct answer: Providing a full prompt to produce the correct response, then re-presenting the SD

Error correction prompts the correct response after an error, then repeats the SD to give the learner an opportunity to respond correctly and receive reinforcement.
