Section A: Foundations of Applied Behavior Analysis (Questions 1–10)
Question 1
A Board Certified Behavior Analyst (BCBA) is designing a functional behavior
assessment (FBA) for a middle school student whose aggressive outbursts have
increased since the start of the academic year. The school team has collected ABC data
for two weeks. The data show that aggression occurs most frequently during
independent math work, is preceded by the teacher presenting a multi-step word
problem, and is followed by the student being sent to the counselor's office (thereby
escaping the assignment). The behavior rarely occurs during group activities or
,preferred tasks. Based on these data, which function of behavior is most strongly
supported?
A. Access to tangible items
B. Access to attention from adults
C. Escape from demand/avoidance of aversive task
D. Automatic/sensory reinforcement
Correct Answer: C
Rationale: The antecedent condition (presentation of a challenging multi-step math
problem) and the maintaining consequence (removal from the assignment via being
sent to the counselor) strongly indicate an escape/avoidance function. The behavior is
context-specific to demanding academic tasks and does not occur during preferred or
social activities, ruling out attention, tangible, and automatic functions.
Question 2
A behavior analyst is reviewing a student's intervention plan that specifies: "When the
student raises his hand and waits quietly, the teacher will provide immediate praise and
a token." The plan also states: "If the student calls out without raising his hand, the
teacher will ignore the behavior and redirect to the hand-raising expectation." This
intervention represents which combination of behavioral procedures?
A. Differential reinforcement of alternative behavior (DRA) and extinction
B. Differential reinforcement of other behavior (DRO) and punishment
C. Differential reinforcement of low rates (DRL) and response cost
,D. Noncontingent reinforcement (NCR) and time-out
Correct Answer: A
Rationale: The intervention reinforces a specific alternative behavior (hand-raising) while
placing the target inappropriate behavior (calling out) on extinction by withholding
reinforcement (ignoring). This is the classic DRA + extinction pairing. DRO would require
reinforcement for the absence of the target behavior during an interval, DRL reinforces
lower rates of the same behavior, and NCR delivers reinforcement independent of
behavior.
Question 3 (SATA — Select All That Apply)
Which of the following are essential components of a valid operational definition of
behavior for use in a behavior intervention plan (BIP)?
A. The definition includes subjective judgments about the student's intent
B. The definition is observable, measurable, and repeatable across observers
C. The definition references internal emotional states (e.g., "frustrated") as primary
identifiers
D. The definition specifies clear boundaries between the target behavior and other
topographically similar behaviors
E. The definition is written in language understandable to all team members
implementing the plan
Correct Answers: B, D, E
, Rationale: A valid operational definition must be objective (B), distinguish the target
behavior from similar behaviors to ensure accurate measurement (D), and be accessible
to all implementers to promote treatment integrity (E). Subjective judgments about
intent (A) and reliance on unobservable internal states (C) compromise interobserver
agreement and measurement validity.
Question 4
During a preference assessment using a multiple-stimulus without replacement
(MSWO) procedure, a BCBA presents an array of six items to a student with autism. The
student selects a tablet first, a snack second, and a puzzle third. The BCBA then
removes the tablet and re-presents the remaining five items. The student selects the
snack, then the puzzle, then a ball. Which statement accurately describes the rank-order
information obtained from this assessment?
A. The assessment yields only dichotomous liked/disliked data for each item
B. The assessment produces a hierarchical preference ranking from most to least
preferred
C. The assessment identifies functional reinforcers but cannot distinguish relative
preference
D. The assessment is invalid because the most preferred item was removed between
trials
Correct Answer: B
Rationale: The MSWO procedure is designed to generate a rank-ordered preference
hierarchy by systematically removing selected items and observing subsequent
choices. The student's consistent selection pattern (tablet > snack > puzzle)
