Questions with Answers & Detailed Rationales
Questions 1–25
1. What is the primary role of a Registered Behavior Technician (RBT)?
A. Diagnose behavioral disorders
B. Develop independent treatment plans
C. Implement behavior-analytic services under the direction of a qualified supervisor
D. Prescribe medication
Rationale: An RBT provides behavior-analytic services under ongoing supervision and does
not independently diagnose or design treatment plans.
2. Which professional is responsible for developing and overseeing a behavior-
analytic treatment plan?
A. RBT
B. Parent
C. Behavior analyst
D. School bus driver
Rationale: The supervising behavior analyst is responsible for assessment, treatment
planning, and clinical oversight.
3. Which is an observable behavior?
A. Anxiety
B. Happiness
C. Crying
D. Motivation
Rationale: Crying can be directly observed and measured, unlike internal states such as
happiness or anxiety.
4. Which operational definition is best for "aggression"?
A. "Acts aggressively when upset."
B. "Has poor behavior."
C. "Hitting another person with an open or closed hand with sufficient force to make
,contact."
D. "Becomes angry."
Rationale: An operational definition describes behavior in observable, measurable terms.
5. What does frequency measure?
A. How long a behavior lasts
B. The number of times a behavior occurs
C. The time between behaviors
D. The intensity of behavior
Rationale: Frequency is the count of occurrences of a behavior.
6. A behavior occurs 12 times during a 3-hour session. What is the frequency rate per
hour?
A. 3
B. 4
C. 9
D. 36
Rationale: Rate = frequency ÷ time. Twelve occurrences divided by 3 hours equals 4
occurrences per hour.
7. What does duration measure?
A. Number of responses
B. Time between responses
C. How long a behavior lasts
D. Number of reinforcers delivered
Rationale: Duration measures the length of time from the beginning to the end of a
behavior.
8. A learner begins screaming at 2:00 p.m. and stops at 2:03 p.m. What is the
duration?
A. 30 seconds
B. 1 minute
C. 2 minutes
D. 3 minutes
Rationale: The behavior lasted from 2:00 to 2:03 p.m., for a total of 3 minutes.
,9. What does latency measure?
A. How long a behavior continues
B. The time between a stimulus and the beginning of a response
C. The total number of responses
D. The intensity of a response
Rationale: Latency is the elapsed time between an instruction or stimulus and the initiation
of the target response.
10. What is interresponse time (IRT)?
A. Time before a behavior starts
B. Time between two successive responses
C. Duration of a behavior
D. Time spent delivering reinforcement
Rationale: IRT measures the interval between one response and the next response.
11. Which measurement records whether a behavior occurred during specific
intervals?
A. Permanent product
B. Partial-interval recording
C. Latency recording
D. Frequency recording
Rationale: Partial-interval recording scores whether the behavior occurred at any point
during an interval.
12. What is whole-interval recording?
A. Behavior must occur at any point in the interval.
B. Behavior must occur throughout the entire interval to be scored.
C. Only the first response is recorded.
D. Only the last response is recorded.
Rationale: Whole-interval recording requires the target behavior to occur for the entire
interval.
13. Which measurement is most appropriate for recording whether a client completed
a worksheet independently?
A. Duration
B. Latency
, C. Permanent product
D. IRT
Rationale: A completed worksheet is a product that remains after the behavior occurs and
can be evaluated later.
14. What is direct observation?
A. Asking another person what happened
B. Reviewing a diagnosis
C. Observing and recording behavior as it occurs
D. Guessing the function of behavior
Rationale: Direct observation involves observing the behavior itself rather than relying solely
on reports.
15. Which is an example of continuous measurement?
A. Momentary time sampling
B. Partial-interval recording
C. Frequency recording
D. Whole-interval recording
Rationale: Continuous measurement records each occurrence or relevant dimension of
behavior during the observation period.
16. A learner engages in hand-flapping during 5 of 10 intervals. What percentage of
intervals contained the behavior?
A. 10%
B. 25%
C. 50%
D. 75%
Rationale: Five intervals divided by 10 total intervals equals 50%.
17. What is reinforcement?
A. Any consequence following behavior
B. A consequence that increases the future likelihood of a behavior
C. A punishment procedure
D. Ignoring behavior
Rationale: Reinforcement is defined by its effect: it increases the future occurrence of the
behavior.
