BCAT PRACTICE EXAM: 200 HIGH-YIELD QUESTIONS WITH
DETAILED RATIONALES
1. Which of the following best describes the primary diagnostic
criterion for Autism Spectrum Disorder (ASD)?
A. Persistent deficits in social communication and social interaction
across multiple contexts
B. Below-average intellectual functioning and adaptive behavior
C. Presence of hallucinations or delusions for at least six months
D. Episodic mood swings between mania and depression
Correct Answer: A
Rationale: ASD is a neurodevelopmental disorder characterized by
persistent deficits in social communication and social interaction, along
with restricted, repetitive patterns of behavior, interests, or activities.
Intellectual disability and mood disorders are separate conditions that
may co-occur but are not core diagnostic criteria.
2. A BCAT is working with a client who engages in severe self-injurious
behavior. The behavior analyst has instructed the technician to
implement a procedure where the client receives no reaction
following each instance of the behavior. Which procedure is being
implemented?
A. Differential reinforcement of other behavior
B. Extinction
C. Response cost
D. Time-out from reinforcement
,Correct Answer: B
Rationale: Extinction involves withholding the reinforcer that previously
maintained a behavior, resulting in a decrease in that behavior over
time. Differential reinforcement of other behavior involves reinforcing
the absence of the target behavior, while response cost and time-out
are punishment-based procedures.
3. A behavior technician records the number of times a client raises
their hand during a 30-minute session. Which measurement
dimension is being used?
A. Duration
B. Latency
C. Frequency
D. Percentage
Correct Answer: C
Rationale: Frequency (also called count or event recording) measures
the number of times a behavior occurs. Duration measures how long a
behavior lasts, latency measures the time between a stimulus and the
onset of a behavior, and percentage expresses the ratio of occurrences
to opportunities.
4. A client is taught to request a break by saying "break please"
instead of engaging in aggression when presented with a difficult task.
This is an example of:
A. Punishment
B. Response cost
C. Functional communication training
D. Overcorrection
,Correct Answer: C
Rationale: Functional communication training (FCT) teaches an
appropriate communicative response that serves the same function as
the problem behavior, replacing it with a more acceptable alternative.
Punishment and response cost are consequence-based procedures
designed to decrease behavior.
5. A BCAT is collecting data on a client's on-task behavior. The
technician observes the client for 10 seconds and records whether the
behavior occurred during the entire interval. Which data collection
method is being used?
A. Partial-interval recording
B. Whole-interval recording
C. Momentary time sampling
D. Event recording
Correct Answer: B
Rationale: Whole-interval recording requires the behavior to be
exhibited throughout the entire observation interval to be scored.
Partial-interval recording scores the behavior if it occurs at any point
during the interval, and momentary time sampling checks whether the
behavior is occurring at the exact moment the interval ends.
6. Which of the following is an example of a conditioned reinforcer?
A. Food
B. Water
C. Tokens
D. Warmth
Correct Answer: C
Rationale: Conditioned reinforcers (also called secondary reinforcers)
, acquire their reinforcing value through pairing with unconditioned
reinforcers such as food, water, or warmth. Tokens are a classic example
of a conditioned reinforcer used in token economies.
7. A BCAT is instructed to provide reinforcement after every fifth
correct response. Which schedule of reinforcement is being used?
A. Fixed ratio
B. Variable ratio
C. Fixed interval
D. Variable interval
Correct Answer: A
Rationale: A fixed ratio schedule delivers reinforcement after a set
number of responses. Variable ratio schedules require an average
number of responses, while interval schedules are based on time rather
than response count.
8. Which of the following is NOT a core deficit associated with Autism
Spectrum Disorder?
A. Deficits in social-emotional reciprocity
B. Deficits in nonverbal communicative behaviors
C. Cognitive delays
D. Deficits in developing and maintaining relationships
Correct Answer: C
Rationale: Cognitive delays are not a core deficit of ASD, although they
may co-occur in some individuals. The core deficits of ASD are in social
communication and interaction, including social-emotional reciprocity,
nonverbal communication, and relationship development.
9. A client engages in tantrum behavior when asked to complete a
math worksheet. The BCAT removes the worksheet contingent on the
