Foundations of Behavior Analysis & Measurement
Q1: A teacher wants to decrease a student's out-of-seat behavior. She notices that the
student leaves his seat to sharpen his pencil, look out the window, and talk to peers.
Instead of targeting "out-of-seat" behavior, she decides to teach the student to raise his
hand for permission. In this scenario, leaving the seat to sharpen a pencil, look out the
window, and talk to peers are all examples of:
A. A stimulus class
B. A response class [CORRECT]
C. An operant conditioning paradigm
D. A respondent reflex arc
Correct Answer: B
Rationale: The correct answer is a response class because all three behaviors, though
topographically different, produce the same environmental change (accessing adult
attention or peer interaction) and are therefore functionally equivalent.
Q2: You are working with a client who is terrified of dogs. Whenever he sees a dog, his
heart rate increases, he begins sweating, and he runs away. Seeing a dog is best
described as a(n):
A. Unconditioned response
B. Conditioned stimulus [CORRECT]
C. Unconditioned reinforcer
D. Operant behavior
Correct Answer: B
Rationale: The correct answer is conditioned stimulus because, through prior learning,
the sight of the dog (a previously neutral stimulus) now elicits an automatic, reflexive
fear response.
Q3: In EDF 6222 we focus on understanding that salivating to the smell of food is
fundamentally different from a rat pressing a lever for food. Salivating is a respondent
behavior because:
,A. It is voluntary and shaped by its consequences
B. It is elicited by an antecedent stimulus [CORRECT]
C. It is maintained by negative reinforcement
D. It operates on the environment to produce a change
Correct Answer: B
Rationale: The correct answer is it is elicited by an antecedent stimulus because
respondent conditioning involves reflexive, involuntary behaviors that are drawn out by
a specific antecedent, rather than being selected by consequences like operant
behaviors.
Q4: Which of the following is an example of an unconditioned reinforcer?
A. Money
B. Praise from a boss
C. Food when you are starving [CORRECT]
D. A gold star on a homework assignment
Correct Answer: C
Rationale: The correct answer is food when you are starving because its reinforcing
value is biological and does not require any prior learning history, unlike money, praise,
or gold stars which are all conditioned reinforcers.
Q5: According to the "dead man's test," which of the following qualifies as a true
behavior?
A. Sitting quietly in a chair during a lecture
B. Not hitting a sibling when frustrated [CORRECT]
C. Being asleep for eight hours
D. Having blue eyes
Correct Answer: B
Rationale: The correct answer is not hitting a sibling because if a dead man can do it
(like sitting quietly or being asleep), it is not a behavior; actively inhibiting a response
requires effort and is therefore a behavior.
Q6: A BCBA is tracking the duration of a client's tantrums. During session one, the client
tantrums for 12 minutes. During session two, the client tantrums for 45 minutes. The
BCBA is measuring which dimension of behavior?
A. Temporal locus
B. Repeatability
C. Temporal extent [CORRECT]
D. Interresponse time
Correct Answer: C
, Rationale: The correct answer is temporal extent because duration measures the total
amount of time a behavior lasts, which perfectly aligns with tracking how long each
tantrum occurs.
Q7: A therapist gives a client a vocal prompt to start a task and records the exact
number of seconds it takes for the client to pick up the pencil. What measurement
procedure is being used?
A. Duration
B. Latency [CORRECT]
C. Interresponse time (IRT)
D. Event recording
Correct Answer: B
Rationale: The correct answer is latency because it measures the amount of time that
passes between the presentation of a specific stimulus (the vocal prompt) and the onset
of the behavior (picking up the pencil).
Q8: A client is engaging in repetitive hand-flapping. The BCBA wants to know how
much time passes between each individual hand flap. The BCBA should measure:
A. Duration
B. Latency
C. Interresponse time (IRT) [CORRECT]
D. Rate
Correct Answer: C
Rationale: The correct answer is interresponse time (IRT) because IRT specifically
measures the elapsed time between the cessation of one response and the onset of the
very next response.
Q9: A teacher wants to track how many times a student vocally stutters during a
30-minute reading period. The student stutters very frequently, sometimes multiple
times per sentence. Which measurement procedure is most appropriate and feasible?
A. Whole-interval recording
B. Partial-interval recording
C. Frequency or event recording [CORRECT]
D. Momentary time sampling
Correct Answer: C
Rationale: The correct answer is frequency or event recording because the behavior
has a clear beginning and end, occurs at a high rate, and can be easily counted without
needing to worry about breaking continuous behaviors into artificial intervals.
