A reversal design can be characterized. Y

*A-B-A-B where baseline A= baseline, B= intervention* A-B where A= baseline B= intervention A-B-C where A=basemine B=intervention 1 C=intervention 2

A reversal design can be designated as

*A-B-Awhere A= baseline, B= intervention* A-B where A= baseline B= intervention A-B-C where A=base line B= intervention 1 C=intervntion 2.

What design is characterized by the following conditions: no intervention for 3 days, tokensystem for 5 days, no intervention for 8 days, token system for 4 days?

*A—B-A-B* B-A A-B-A-C

*What design is characterized by the following conditions: token system for 3 days, no intervention for 5 days token system for 8 days?

*B-A-B* A-B-A-B A-B-A-C

A functional relation using design calls for (minimally)

*Two alterations between baseline and a particular intervention.* Baseline and two intervntions Baseline followed by implemention in a step wise fashion across subjects

In an A-B-A design, a reversal occurs when

*baseline is re-introduced and the behavior approximates the level during the original baseline.* Baseline is

Potential scientific and social disadvantages of the reversal design include, which of the following?

*irreversibility of treatment effects and ethical concerns when stopping effective treatment* Irreversibility of treatment effects and ethical concerns when stopping ineffective treatment Maintenance of treatment effects and ethical concerns when stopping effective treatment Reversibility of treatment effects and ethical concerns when stopping effective treatment

Introducing, withdrawing, and re-introducing an independent variable is characteristic of

*reversal design* An alternating treatments design. A multiple treatments design

With a reversal design, each reversal

*strengthens the demonstration of experimental control* Weakens the demonstration of generalization Strengthens the demonstration of generalization

*What design is characterized by the following conditions: no intervention for 3 days, token system for 5 days, no intervention for 8 days token system for 4 days?*

A B A C B A B *A B A B*

A multiple treatments design may be designated as

A b C A baseline B intervention 1 C intervention 2 Ab where a baseline b intervention *A b a c a where A baseline b intervention 1 c intervention 2*

Which could provide the strongest demonstration of experimental control?

A-B-A *A-B—A-B-A* A-B-C-A B-A-B

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-C *B-A-B* B-A

Reversal designs require that each condition is

Shorter than the previous condition to demonstrate rapid change *Long enough to achieve a steady state of representative responding* That same length as other conditions so the number of data points are equal
