WELL REVISED ANSWERS - LATEST AND

SOLUTIONS – ASSURES PASS
1. A BCaBA is asked to assist in designing an intervention to increase
independent task completion. Which principle most directly justifies using
differential reinforcement rather than punishment as a first-line strategy?
A. Punishment produces faster behavior change
B. Reinforcement-based procedures are less restrictive and align with
ethical standards
C. Differential reinforcement eliminates the need for data collection
D. Reinforcement procedures require less training
Italicized rationale: Ethical and professional standards prioritize the least
restrictive, reinforcement-based interventions before considering
punishment.
2. During baseline data collection, a learner’s behavior shows high variability
with no clear trend. What is the MOST appropriate next step before
implementing an intervention?
A. Begin treatment immediately
B. Extend baseline to obtain stable responding
C. Average the data points
D. Switch measurement systems
, Italicized rationale: Stable baseline data are necessary to demonstrate
experimental control and evaluate intervention effects.
3. A behavior analyst defines aggression as “any instance of hitting, kicking, or
biting another person with force.” This is an example of:
A. An inferred construct
B. An incomplete definition
C. An operational definition
D. A hypothetical explanation
Italicized rationale: Operational definitions specify observable and
measurable dimensions of behavior.
4. Which schedule of reinforcement is MOST resistant to extinction?
A. Fixed ratio
B. Fixed interval
C. Variable interval
D. Variable ratio
Italicized rationale: Variable ratio schedules produce high, steady response
rates and strong resistance to extinction.
5. A BCaBA observes that problem behavior increases immediately after
demands are placed. Which function is MOST likely?
A. Automatic reinforcement
B. Escape from demands
C. Access to tangibles
D. Social attention
Italicized rationale: Problem behavior temporally linked to task demands
commonly serves an escape function.
6. Which measurement system is BEST for behaviors with a clear beginning
and end?
, A. Partial-interval recording
B. Frequency recording
C. Whole-interval recording
D. Momentary time sampling
Italicized rationale: Frequency recording accurately captures discrete
responses.
7. A client engages in hand flapping continuously for long periods. Which
measurement system is MOST appropriate?
A. Frequency
B. Rate per minute
C. Duration recording
D. Permanent product
Italicized rationale: Duration recording captures how long a behavior
occurs.
8. Which is an example of a motivating operation?
A. Reinforcing correct responses
B. Presenting a discriminative stimulus
C. Food deprivation increasing the value of food
D. Delivering a prompt
Italicized rationale: Motivating operations alter the value of a reinforcer
and the probability of behavior.
9. A BCaBA graphs data daily to visually inspect behavior change. This
practice supports which analytic dimension of ABA?
A. Technological
B. Conceptual
C. Analytic
D. Behavioral
, Italicized rationale: Visual analysis demonstrates a functional relation
between intervention and behavior.
10.Which prompt is MOST intrusive?
A. Gestural
B. Verbal
C. Model
D. Physical guidance
Italicized rationale: Physical prompts involve direct contact and are the
most intrusive.
11.A BCaBA notices that reinforcement is delivered inconsistently across staff.
What is the MOST likely effect?
A. Increased stimulus control
B. Reduced treatment integrity and effectiveness
C. Faster acquisition
D. Automatic generalization
Italicized rationale: Inconsistent implementation undermines treatment
fidelity.
12.A scatterplot is MOST useful for identifying:
A. Response rate
B. Treatment effects
C. Temporal patterns of behavior occurrence
D. Interobserver agreement
Italicized rationale: Scatterplots display when behavior occurs across time
periods.
13.Which ethical requirement applies directly to a BCaBA’s scope of practice?
A. Independent case supervision
B. Working under the supervision of a BCBA
