ABAT - Applied Behavior Analysis Autism Core Knowledge Questions and Answers 5 — Questions and Answers
Question 1: A child is taught to ask for 'more' using a picture card when given access to a preferred item. Over sessions, the instructor begins delaying the presentation of the picture card to encourage spontaneous requests. This procedure is called:
- Stimulus fading
- Time delay prompting (Correct answer)
- Errorless teaching
- Stimulus generalization
Correct answer: Time delay prompting
Time delay prompting involves inserting a pause between the discriminative stimulus and the prompt, giving the learner the opportunity to respond before the prompt is delivered.
Question 2: According to the BACB Ethics Code, when a client's treatment team disagrees about intervention goals, the behavior analyst's primary obligation is to:
- Defer to the highest-ranking professional on the team
- Advocate for the client's best interests and rights (Correct answer)
- Follow the parents' preferences regardless of professional opinion
- Document the disagreement and take no action
Correct answer: Advocate for the client's best interests and rights
The BACB Ethics Code requires behavior analysts to prioritize the client's wellbeing and rights above other stakeholder preferences when conflicts arise.
Question 3: A behavior technician is implementing a token economy with a child with autism. The tokens function as:
- Unconditioned reinforcers
- Generalized conditioned reinforcers (Correct answer)
- Primary reinforcers
- Negative reinforcers
Correct answer: Generalized conditioned reinforcers
Tokens are generalized conditioned reinforcers because they are paired with many backup reinforcers, giving them broad reinforcing value independent of any single deprivation state.
Question 4: During a preference assessment, a BCBA presents two items simultaneously and records which item the learner approaches first across many trials. This method is called:
- Single-stimulus preference assessment
- Paired stimulus (forced choice) preference assessment (Correct answer)
- Multiple stimulus with replacement (MSWO)
- Free operant observation
Correct answer: Paired stimulus (forced choice) preference assessment
The paired stimulus (forced choice) preference assessment presents two items at a time and identifies relative preference based on approach responses across all possible pairs.
Question 5: Stimulus overselectivity, commonly observed in individuals with autism, refers to:
- Responding to too many aspects of a stimulus complex
- Responding to only one or a limited subset of cues in a multi-element stimulus (Correct answer)
- Generalizing a response to stimuli that are too dissimilar
- Over-relying on verbal instructions while ignoring environmental cues
Correct answer: Responding to only one or a limited subset of cues in a multi-element stimulus
Stimulus overselectivity occurs when a learner responds to only part of a compound stimulus, which can interfere with learning and generalization.
Question 6: Which of the following BEST describes the purpose of a 'Behavior Intervention Plan' (BIP)?
- To document the baseline data collected prior to any intervention
- To outline antecedent modifications, replacement behaviors, and consequence strategies based on the FBA (Correct answer)
- To provide a daily schedule of ABA therapy sessions for the client
- To summarize the client's diagnosis and medical history for the treatment team
Correct answer: To outline antecedent modifications, replacement behaviors, and consequence strategies based on the FBA
A BIP is a written plan derived from the FBA that specifies antecedent strategies, replacement behaviors to teach, and consequence procedures to address problem behavior.
Question 7: A behavior analyst teaches a child with autism to greet peers first with a full physical prompt, then a model, then a gesture, and finally without any prompt. This is an example of which teaching strategy?
- Least-to-most prompting
- Most-to-least prompting (Correct answer)
- Simultaneous prompting
- Graduated guidance
Correct answer: Most-to-least prompting
Most-to-least prompting begins with the most intrusive level of assistance and systematically fades to less intrusive prompts as the learner demonstrates competency.
