1. In a reversal design, which of the following is the primary purpose of returning to the
baseline (A2) phase?
A. To verify the prediction made in the initial baseline phase.
B. To demonstrate the social validity of the intervention.
C. To provide a second opportunity for the participant to learn the skill.
D. To increase the external validity of the findings.
Answer: A
Conceptual Explanation: Returning to baseline (A2) is used to verify the prediction made
from the initial baseline (A1) data path, showing that behavior would have remained at
baseline levels without the intervention.
2. Which interobserver agreement (IOA) method is considered the most stringent for
behaviors that occur at very low rates?
A. Scored-interval IOA
,B. Mean count-per-interval IOA
C. Total count IOA
D. Unscored-interval IOA
Answer: A
Conceptual Explanation: Scored-interval IOA (also known as occurrence IOA) is the most
stringent for low-rate behaviors because it only considers intervals where at least one
observer recorded the behavior.
3. A researcher is studying the effects of three different levels of praise on task completion.
This is an example of a:
A. Component analysis
B. Parametric analysis
C. Comparative analysis
D. Sequence analysis
Answer: B
Conceptual Explanation: A parametric analysis seeks to discover the differential effects of
a range of values of the independent variable.
4. When using a multiple baseline design, experimental control is demonstrated when:
A. The researcher returns to baseline after a successful treatment phase.
B. The behavior changes in all tiers simultaneously after the first intervention.
, C. The trend in the first baseline remains stable while the second baseline increases.
D. The behavior changes only when the intervention is introduced to each tier.
Answer: D
Conceptual Explanation: Experimental control in a multiple baseline design is shown by
the staggered onset of the intervention causing change only in the targeted tier while other
tiers remain stable.
5. Which of the following is a limitation of the Alternating Treatments Design (ATD)?
A. It requires the withdrawal of an effective intervention.
B. It takes a long time to reach a conclusion.
C. It is susceptible to multiple treatment interference.
D. It cannot be used with unstable data.
Answer: C
Conceptual Explanation: Multiple treatment interference occurs when the effects of one
treatment are influenced by the presence of another treatment in the same study.
6. Which threat to internal validity refers to the effects of an observer’s expectations on the
data they record?
A. Observer drift
B. Reactivity
C. Maturation
