PREPARATION
1. A BCBA is teaching a newly hired Registered Behavior Technician (RBT) how to collect
frequency data. Which action should occur first?
A. Review intervention procedures
B. Establish data collection definitions
C. Conduct treatment integrity checks
D. Analyze baseline trends
Correct Answer: B. Establish data collection definitions
Rationale:
Operational definitions ensure consistent measurement before data collection begins. The other
actions are important but depend on clearly defined target behaviors.
2. Which measurement system is most appropriate for counting the number of times a
student raises a hand during class?
A. Frequency
B. Duration
C. Latency
D. Percentage
Correct Answer: A. Frequency
Rationale:
Frequency directly measures how often a behavior occurs. Duration measures time, latency measures
delay, and percentage requires a different calculation.
3. A behavior occurs at a high rate and for brief durations. Which recording method is
typically most effective?
A. Duration recording
B. Permanent product recording
C. Frequency recording
D. Whole interval recording
Correct Answer: C. Frequency recording
Rationale:
Frequency recording is ideal for discrete, countable behaviors occurring repeatedly within an
observation period.
4. A supervisor notices inconsistent scoring between observers. What should be assessed
first?
A. Treatment integrity
B. Interobserver agreement
, C. Social validity
D. Generalization
Correct Answer: B. Interobserver agreement
Rationale:
Low agreement suggests observers may not be measuring behavior consistently. Reliable
measurement is essential before evaluating other variables.
5. Which graph is most commonly used in behavior analysis to display changes over time?
A. Scatterplot
B. Pie chart
C. Histogram
D. Line graph
Correct Answer: D. Line graph
Rationale:
Line graphs allow visual analysis of trends, variability, and level changes across time.
6. A learner receives praise immediately after completing a task. The praise functions as:
A. Punishment
B. Motivating operation
C. Reinforcement
D. Extinction
Correct Answer: C. Reinforcement
Rationale:
If praise increases future task completion, it is functioning as reinforcement.
7. Which concept refers to a stimulus change that alters the effectiveness of a reinforcer?
A. Discrimination
B. Motivating operation
C. Prompt hierarchy
D. Chaining
Correct Answer: B. Motivating operation
Rationale:
Motivating operations affect both the value of consequences and the likelihood of related behaviors.
8. A behavior decreases because reinforcement is no longer delivered. This procedure is
called:
A. Shaping
B. Chaining
C. Extinction
D. Pairing
Correct Answer: C. Extinction
Rationale:
Extinction involves discontinuing reinforcement that previously maintained a behavior.
, 9. Which schedule delivers reinforcement after a fixed number of responses?
A. Variable interval
B. Fixed interval
C. Variable ratio
D. Fixed ratio
Correct Answer: D. Fixed ratio
Rationale:
Fixed-ratio schedules provide reinforcement after a specified response count.
10. A BCBA identifies environmental events occurring before a problem behavior. These events
are known as:
A. Consequences
B. Establishing operations
C. Antecedents
D. Reinforcers
Correct Answer: C. Antecedents
Rationale:
Antecedents occur before behavior and may influence its occurrence.
11. A learner receives a token each time a worksheet is completed. The token is functioning as
a:
A. Conditioned reinforcer
B. Unconditioned reinforcer
C. Punisher
D. Prompt
Correct Answer: A. Conditioned reinforcer
Rationale:
Tokens acquire value through association with backup reinforcers.
12. Which assessment directly tests behavioral function by manipulating environmental
variables?
A. Preference assessment
B. Functional analysis
C. Interview
D. Checklist
Correct Answer: B. Functional analysis
Rationale:
Functional analysis experimentally evaluates cause-and-effect relationships between variables and
behavior.
13. A practitioner gradually teaches a complex skill by reinforcing successive approximations.
This process is called:
A. Chaining
B. Modeling
