Applied Behavior Analysis Cooper et al Chapter 8 Reversal and Alternating Treatment Designs

A-B-A design

an experimental design consisting of an initial baseline phase, an intervention phase, and a return to baseline conditions by withdrawing the independent variable to see whether responding "reverses" to levels observed in the initial baseline phase

A-B-A-B design

An experimental design consisting of an initial baseline phase, an initial intervention phase, a return to baseline condition, and a second intervention phase

alternating treatments design

an experimental design in which two or more conditions are presented in rapidly alternating succession independent of the level of responding

B-A-B design

an experimental design that begins with the treatment condition

DRI/DRA reversal technique

an experimental technique that demonstrates the effects of reinforcement using a differential reinforcement of an incompatible or alternative behavior (DRI/DRA) as a control condition instead of a no-reinforcement condition

DRO reversal technique

an experimental technique for demonstrating the effects of reinforcement by using differential reinforcement of other behavior (DRO) as a control condition instead of a no-reinforcement condition

irreversibility

a situation that occurs when the level of responding observed in a previous phase cannot be reproduced even though the experimental conditions are the same as they were during the earlier phase

multielement design

also knows as alternating treatments design

multiple treatment interference

the effects of one treatment on a subject's behavior being confounding by the influence of another treatment administered in the same study

multiple treatment reversal design

any experimental design that uses the experimental methods and logic of the reversal tactic to compare the effects of two or more experimental conditions to baseline and/or to one another

(NCR) reversal technique

an experimental control technique that demonstrates the effects of reinforcement by using noncontingent reinforcement (NCR) as a control condition instead of a no-reinforcement condition

reversal design

any experimental design in which the researcher attempts to verify the effect of the independent variable by "reversing" responding to a level obtained in a previous condition

sequence effects

the effects on a subject's behavior in a given condition that are the result of the subject's experience with a prior condition

withdrawal design

a term used by some authors as a synonym for A-B-A-B design; also used to describe experiments in which an effective treatment is sequentially or partially withdrawn to promote the maintenance of behavior changes
