Exam Coverage
• ABA principles: reinforcement, punishment, extinction
• Behavior assessment: FBA, measurement, data collection
• Data analysis: IOA, trend, baseline
• Reinforcement: types, schedules
• Punishment: positive, negative, ethical considerations
• Behavior reduction: DRO, DRA, DRL, FCT, response cost
• Behavior acquisition: shaping, chaining, DTT, prompting
• Generalization and maintenance
• Ethics: BACB code, confidentiality, consent
• Practical BIP development, treatment integrity, case studies

,Page 2 of 119
1. Which of the following best describes the principle of positive reinforcement in ABA?
A. Adding a stimulus to increase the likelihood of a behavior
B. Removing a stimulus to increase behavior
C. Adding a stimulus to decrease behavior
D. Ignoring behavior to reduce its occurrence
Correct Answer: A
Rationale: Positive reinforcement involves presenting a stimulus following a behavior to
increase its future frequency.
2. Which ABC component refers to the event occurring immediately before a behavior?
A. Antecedent
B. Behavior
C. Consequence
D. Extinction
Correct Answer: A
Rationale: The antecedent is the trigger or cue for a behavior in the ABC model.
3. What is the primary purpose of a functional behavior assessment (FBA)?
,Page 3 of 119
A. Identify the function of challenging behavior to guide interventions
B. Teach new skills exclusively
C. Measure academic performance
D. Graph behavior data without interpretation
Correct Answer: A
Rationale: FBAs determine why a behavior occurs, helping design effective interventions.
4. Which data collection method records the exact time a behavior begins and ends?
A. Duration recording
B. Frequency recording
C. Interval recording
D. Momentary time sampling
Correct Answer: A
Rationale: Duration recording captures the total time a behavior occurs.
5. When is continuous measurement most appropriate?
A. For high-frequency behaviors where every occurrence matters
B. For behaviors occurring rarely
, Page 4 of 119
C. For collecting demographic information
D. For measuring skill acquisition only
Correct Answer: A
Rationale: Continuous measurement tracks every occurrence of the target behavior.
6. Which schedule of reinforcement provides a reward after an unpredictable number of
responses?
A. Variable ratio
B. Fixed ratio
C. Fixed interval
D. Variable interval
Correct Answer: A
Rationale: Variable ratio reinforcement delivers reinforcement unpredictably based on
response count.
7. What is the difference between positive and negative punishment?
A. Positive adds stimulus, negative removes stimulus, both reduce behavior
B. Both add stimulus to reduce behavior
