,Q1. In a systems-wide positive behavior support implementation, a researcher uses a
concurrent multiple-baseline design across three schools. Baseline data show stable
low rates of student office discipline referrals (ODR). Intervention is introduced at
staggered times across schools. What threat to internal validity is least controlled by
this design and could be addressed by adding a control group?
A. Instrumentation
B. Selection bias
C. Maturation
D. History
Correct Answer: D. History
Rationale: History is a threat when events outside the experiment coincide with
intervention introduction. In multiple-baseline designs, history is partially controlled
because the intervention is staggered, but an external event could affect all schools
simultaneously. Adding a non-intervention control group helps isolate history effects.
Instrumentation is controlled by consistent measurement, maturation is controlled by
baseline trends, and selection bias is less relevant as this is a quasi-experiment with intact
groups.
Why Wrong:
A - Instrumentation threat is minimal because the same ODR recording system is used
across phases and schools.
B - Selection bias is not a primary threat since the design uses the same schools across
phases; a control group could reduce differential selection.
C - Maturation would be evidenced by trends in baseline; staggered introduction helps
rule out maturation.

University Press. Chapter 7.
Q2. A behavior analyst designs a token economy for a classroom. Students earn
tokens for academic engagement and exchange them for backup reinforcers. After
four weeks, engagement plateaus. Which ethical consideration most directly requires
the analyst to modify the system, according to the Behavior Analyst Certification
Board's Ethics Code?
A. Ensuring that the token economy does not restrict students' rights to fair educational
opportunities
B. Using the least restrictive procedures that are likely to be effective
C. Obtaining ongoing informed consent from parents and guardians
D. Maintaining client dignity by avoiding coercive control
Correct Answer: B. Using the least restrictive procedures that are likely to be
effective
Page 3
, Rationale: The Ethics Code (BACB, 2020) requires behavior analysts to use the least
restrictive procedures. A plateau suggests the current system may no longer be effective,
and a more restrictive change (e.g., increasing token value) could be considered, but the
principle of least restrictiveness demands first trying less intrusive modifications (e.g.,
varying backup reinforcers). Option A relates to rights, but the primary issue here is
effectiveness. Consent (C) is ongoing but not directly triggered by a plateau. Dignity (D) is
important but the plateau itself does not necessarily indicate coercion-it indicates a need
for procedural modification.
Why Wrong:
A - Rights to educational opportunity are broad but not specifically about token
economy effectiveness.
C - Informed consent is ongoing but a plateau does not necessarily require re-consent
unless procedures change substantially.
D - While important, client dignity is not the primary ethical principle directly
addressing the need to modify an ineffective system.
Reference: Behavior Analyst Certification Board. (2020). Ethics Code for Behavior
Analysts. Section 4.04 (Least Restrictive Procedures).
Q3. A systems analyst conducts a performance diagnostic for a call center. The staff
are trained in the correct script, but average call duration remains too long.
Immediate performance feedback is given but fails to reduce duration. According to
behavioral systems analysis, which systemic variable is most likely responsible for the
persistent inefficiency?
A. Antecedents are not adequately prompting the desired behavior
B. Consequences for fast versus slow calls are undifferentiated
C. Staff lack prerequisite skills despite initial training
D. The physical layout of the call center creates delays
Correct Answer: B. Consequences for fast versus slow calls are undifferentiated
Rationale: Behavioral systems analysis emphasizes aligning consequences with desired
performance. Since staff are trained (antecedents and skills are in place) but call duration
is long, the likely cause is that consequences (e.g., if customers are satisfied but managers
don't differentiate based on speed, or if longer calls reduce errors and avoid complaints)
do not differentially reinforce shorter calls. Feedback alone may not be a sufficiently
powerful consequence. Option A is ruled out because the script is present. Option C is
ruled out because training was effective. Option D is possible but less likely given the
focus on feedback and the principle that consequences drive behavior.
Why Wrong:
A - Antecedents are present (script) and staff are trained, so lack of prompting is not
the primary issue.
C - Staff have been trained and initial training was effective, so prerequisite skills are
not deficient.
