RBT - Registered Behavior Technician Assessment Test #3 1 — Questions and Answers
Question 1: A behavior technician records whether a target behavior occurred at least once during each 10-minute interval of a session. Which data collection method is being used?
- Continuous frequency recording
- Partial-interval recording (Correct answer)
- Whole-interval recording
- Momentary time sampling
Correct answer: Partial-interval recording
Partial-interval recording scores an interval as positive if the behavior occurs at least once during that interval, regardless of duration or frequency. It tends to overestimate behavior occurrence.
Question 2: During discrete trial training, the period between the learner's response and the delivery of the next SD is called the:
- Inter-trial interval (Correct answer)
- Latency period
- Intertrial response
- Response delay
Correct answer: Inter-trial interval
The inter-trial interval (ITI) is the brief pause between the end of one trial (including consequence delivery) and the start of the next SD. It helps the learner discriminate between trials.
Question 3: A client consistently requests a break when presented with difficult tasks. If the RBT continues to provide breaks following these requests, the break is most likely functioning as:
- A punisher
- A positive reinforcer
- A negative reinforcer (Correct answer)
- An unconditioned stimulus
Correct answer: A negative reinforcer
When a behavior (requesting a break) is maintained by the removal of an aversive stimulus (the difficult task), the consequence is negative reinforcement. The behavior increases because an unpleasant event is terminated.
Question 4: Which chaining procedure teaches the first step of a task analysis first and adds subsequent steps one at a time in order?
- Backward chaining
- Total task chaining
- Forward chaining (Correct answer)
- Simultaneous chaining
Correct answer: Forward chaining
Forward chaining begins instruction with the first step in the task analysis and adds steps sequentially until the entire chain is completed independently. The learner masters step 1 before step 2 is introduced.
Question 5: An RBT is asked to conduct a paired-stimulus preference assessment. What does this procedure involve?
- Presenting items one at a time and recording approach responses
- Presenting all preferred items simultaneously and allowing free choice
- Presenting two items at a time and recording which item the client selects (Correct answer)
- Asking the caregiver to rank the client's preferred items
Correct answer: Presenting two items at a time and recording which item the client selects
In a paired-stimulus (forced-choice) preference assessment, two items are presented simultaneously on each trial and the client selects one. Items are systematically paired so each appears with every other item, producing a preference hierarchy.
Question 6: A behavior that was previously reinforced is no longer producing reinforcement. Over time the behavior decreases. This process is called:
- Habituation
- Satiation
- Extinction (Correct answer)
- Punishment
Correct answer: Extinction
Extinction is the procedure of withholding reinforcement for a previously reinforced behavior, resulting in a decrease in that behavior over time. It is distinct from punishment, which involves adding an aversive consequence or removing a positive one contingent on behavior.
