SECTION 1: SINGLE-SUBJECT RESEARCH DESIGNS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A behavior analyst is working with a 3rd grader who engages in high rates of disruptive
outbursts during math instruction. After collecting 5 days of baseline data, the analyst
implements a token economy for 10 days, then withdraws the tokens for 5 days, and
finally reintroduces them for 10 days.
A. Reversal (ABAB) design ✓ CORRECT
B. Multiple baseline across subjects design
C. Changing criterion design
D. Alternating treatments design
Correct Answer: A
Rationale: The ABAB design systematically introduces, withdraws, and reintroduces the
intervention to demonstrate experimental control by observing behavior change in
tandem with the independent variable. Multiple baseline designs do not withdraw the
,intervention, and changing criterion designs manipulate performance standards rather
than presence or absence of the intervention. This design is powerful but requires that
the behavior reverses when the intervention is removed.
Question 2 of 50
A researcher wants to evaluate a social skills training program across three elementary
classrooms without removing the intervention once it has been implemented.
A. Reversal design
B. Multiple probe design ✓ CORRECT
C. Withdrawal design
D. Changing criterion design
Correct Answer: B
Rationale: The multiple probe design allows the researcher to evaluate the intervention
across settings or behaviors without withdrawing it, which is essential when reversal is
impractical or unethical. Baseline probes are conducted intermittently until the
intervention is introduced for each classroom in a staggered fashion. This design is
commonly used in educational settings where skills should not be taken away from
students.
Question 3 of 50
A BCBA is evaluating a self-monitoring intervention for a 16-year-old student. The
student earns reinforcement for achieving 70% accuracy during week one, 80% during
week two, and 90% during week three.
A. Multiple baseline design
B. Reversal design
C. Changing criterion design ✓ CORRECT
D. Multielement design
Correct Answer: C
, Rationale: The changing criterion design demonstrates experimental control by
systematically raising the performance criterion required for reinforcement and showing
that behavior changes in step with each new criterion. This design is particularly useful
for shaping behaviors toward a terminal goal. Each phase must show stable responding
at the new criterion before advancing.
Question 4 of 50
A researcher compares two reading fluency interventions by presenting peer tutoring on
Monday and Wednesday and computer-assisted instruction on Tuesday and Thursday,
with the order counterbalanced across weeks.
A. Multiple baseline design
B. Reversal design
C. Alternating treatments (multielement) design ✓ CORRECT
D. Changing criterion design
Correct Answer: C
Rationale: Rapid alternation between two or more conditions within the same phase is
the defining feature of the alternating treatments design, which allows quick
comparison of differential effectiveness. The conditions must be distinct and the
alternation rapid enough to minimize carryover effects. Counterbalancing the order of
conditions controls for sequence effects.
Question 5 of 50
A BCBA wants to evaluate a parent training program that teaches families to implement
bedtime routines. Once parents learn the skills, they cannot realistically be asked to
stop using them.
A. Use a reversal design to demonstrate experimental control
B. Use a multiple baseline design across parents or behaviors ✓ CORRECT
C. Use an AB design because reversal is impossible
