Withdrawal/Reversal Design

Question 1

In an A-B-A design, A reversal occurs when…
A. The intervention is introduced and the behavior remains at the level during the original baseline
B. Baseline is re-introduced and the behavior approximates the level during the original baseline
C. Baseline is re-introduced and the behavior is maintained
D. Baseline is re-introduced in the behavior returns to the level during the original intervention

Answer 1

B
For a reversal to occur the behavior must approximate the level during the original baseline condition

Question 2

A multiple treatments design may be designated as…
A. B-C-A
B. A-B-C, A=baseline, B=intervention, C=intervention 2
C. A-B
D. A-B-A-C-A, A=baseline, B=intervention, C=intervention 2

Answer 2

D

Question 3

What design is characterized by the following conditions: token system for 3 days, no intervention for 5 days, token system for 8 days?
A. B-A-B
B. A-B-A-B
C. A-B-A-C
D. B-A

Answer 3

A

Question 4

With a reversal design, each reversal…
A. Strengthens the demonstration of generalization
B. Weakens the demonstration of generalization
C. Strengthens the demonstration of experimental control
D. Weakens the demonstration of experimental control

Answer 4

C

Question 5

A reversal design can be designated as…
A. A-B-C-A
B. A-B
C. A-B-C
D. A-B-A

Answer 5

D

Question 6

Answer 6

D

The data suggests a cyclic pattern. If you started now, you could not be sure whether subsequent improvement is due to the intervention or whether it is part of the natural cyclic pattern. If possible, control for the source of variability or cycle before implementing your intervention.

Question 7

Answer 7

D

The data are improving without an intervention, so wait until a steady state is achieved. Perhaps you won’t need the intervention.

Question 8

Answer 8

D

If you started now, the variability (ups and downs) of the data would thwart a demonstration of experimental control.
