1. A behavior analyst is working with a client who frequently engages in disruptive
vocalizations during independent academic tasks. The analyst records the time elapsed
from the teacher's instruction to the onset of the client's first disruptive vocalization.
Which measure of behavior is being collected?
A. Duration
B. Interresponse time
C. Latency
D. Response rate
Latency measures the time between the presentation of a stimulus (e.g., the teacher's
instruction) and the initiation of the response. Duration measures the total time of the
response, while interresponse time measures the time between two consecutive responses.
2. A supervisor uses Behavioral Skills Training (BST) to teach a new Registered Behavior
Technician (RBT) how to implement a discrete trial training teaching procedure. Which of
the following represents the correct sequence of BST components?
A. Instructions, Modeling, Rehearsal, Feedback
B. Modeling, Instructions, Feedback, Rehearsal
C. Instructions, Rehearsal, Modeling, Feedback
D. Rehearsal, Feedback, Instructions, Modeling
Behavioral Skills Training (BST) consists of four sequential steps: providing verbal/written
instructions, modeling the target skill, having the learner rehearse the skill, and providing
immediate corrective and praise-based feedback.
3. An RBT records whether a stereotypic behavior occurs at the exact moment a timer
sounds every 15 minutes. Which continuous or discontinuous measurement system is being
utilized?
A. Partial-interval recording
B. Whole-interval recording
C. Momentary time sampling
D. Frequency counting
Momentary time sampling involves observing whether a behavior is occurring at the precise
end of a pre-determined interval. It does not require continuous observation throughout the
interval, unlike whole or partial-interval recording.
,4. A BCBA conducts a Functional Behavior Assessment (FBA) and determines that a
student's off-task behavior is maintained by escape from difficult math tasks. Which of the
following antecedent manipulations is directly function-based?
A. Providing high-preference stickers contingently upon task completion
B. Reducing the difficulty or length of the math worksheet
C. Delivering a 30-second reprimand whenever off-task behavior occurs
D. Implementing a time-out procedure following off-task behavior
Reducing task difficulty directly modifies the establishing operation (EO) for escape-
maintained behavior by making the task less aversive, serving as a functional antecedent
intervention. High-preference stickers address attention/tangible functions, while reprimands
and time-out are post-behavior consequences.
5. A behavior analyst wants to evaluate the effects of a token economy on three distinct,
independent behaviors of a single client across the same setting. Which single-case
experimental design is most appropriate?
A. Reversal design
B. Alternating treatments design
C. Multiple baseline across behaviors design
D. Changing criterion design
A multiple baseline across behaviors design allows the evaluation of a single intervention
across multiple independent behaviors without needing to withdraw the effective
intervention, making it ideal for evaluating a token economy targeting multiple behaviors.
6. Which philosophical attitude of behavior analysis demands that objective observation
and scientific measurement take precedence over personal beliefs or intuition?
A. Determinism
B. Empiricism
C. Parsimony
D. Philosophical doubt
Empiricism is the practice of objective observation and measurement of the phenomena of
interest. It forms the primary cornerstone of behavior analysis as a scientific discipline.
7. A child receives a edible reinforcement every time they complete an average of 5 task
completions (sometimes 3, sometimes 7, sometimes 5). What schedule of reinforcement is
being implemented?
A. Fixed-Ratio (FR 5)
B. Variable-Interval (VI 5)
C. Variable-Ratio (VR 5)
,D. Fixed-Interval (FI 5)
A Variable-Ratio schedule delivers reinforcement after an average number of responses.
Because reinforcement depends on the number of task completions rather than time, it is a
ratio schedule with a variable requirement.
8. During a paired-stimulus preference assessment, how are items presented to the learner?
A. One item at a time until all items have been presented
B. In pairs, side-by-side, until every item has been paired with every other item
C. All items presented simultaneously in a array
D. Allowing continuous free access to all items in an enriched environment
A paired-stimulus (forced-choice) preference assessment presents two items simultaneously,
requiring the learner to choose one. Every item is systematically paired with every other item
to create a ranked hierarchy of preferences.
9. When a behavior analyst removes a pre-existing preferred item or privilege contingent
upon the occurrence of a target behavior, resulting in a future decrease in that behavior,
which process has occurred?
A. Positive punishment
B. Negative reinforcement
C. Response cost
D. Extinction
Response cost is a form of negative punishment that involves the withdrawal of specific
quantities of a reinforcer contingent upon a target behavior, decreasing the future probability
of that behavior.
10. A learner says "dog" only when presented with a picture of a dog, and not when
presented with pictures of cats, horses, or cows. This outcome demonstrates which
concept?
A. Stimulus generalization
B. Stimulus control
C. Response generalization
D. Equivalence class derivation
Stimulus control occurs when a behavior is emitted more frequently in the presence of an
antecedent stimulus (S-D) than in its absence, due to a history of differential reinforcement.
11. Which form of functional behavior assessment involves manipulating antecedent and
consequent variables in controlled, analogue conditions to demonstrate causal
relationships?
, A. Indirect assessment
B. Descriptive assessment
C. Functional analysis
D. ABC continuous recording
A functional analysis is an experimental assessment method that manipulates environmental
variables to directly demonstrate functional (causal) relationships between behavior and the
environment.
12. A behavior analyst is measuring the duration of tantrums. What is the most critical
requirement for ensuring accurate measurement across multiple observers?
A. An operational definition with clear objective boundaries and onset/offset criteria
B. Collecting baseline data for at least 30 days
C. Using a partial-interval recording sheet
D. Informing the client that they are being observed
An operational definition must be objective, clear, and complete, specifying exact onset and
offset criteria to ensure consistent measurement and high interobserver agreement across
observers.
13. A client engages in self-injurious head-hitting that is reinforced by automatic sensory
stimulation. Which differential reinforcement procedure is most appropriate when any
non-occurrence of the behavior for a specified interval results in reinforcement?
A. Differential Reinforcement of Alternative Behavior (DRA)
B. Differential Reinforcement of Incompatible Behavior (DRI)
C. Differential Reinforcement of Other Behavior (DRO)
D. Differential Reinforcement of Low Rates (DRL)
DRO delivers a reinforcer contingent upon the absence or non-occurrence of the target
behavior throughout a specified time interval, regardless of what other behavior occurs.
14. A BCBA wants to teach a student to brush their teeth using backward chaining. Where
does direct instruction begin?
A. On the very first step of the task analysis
B. Simultaneously on all steps of the task analysis
C. On the final step of the task analysis while the trainer completes all previous steps
D. On a randomly selected step each session
In backward chaining, the trainer completes all initial steps of the task analysis except the last
step. The learner is taught to perform the final step to immediately receive the natural
reinforcer of task completion.
