Reversal & Alternating Treatments Designs Flashcards
A-B-A design
experiment entailing on reversal (Baseline-treatment-baseline)
A-B-A-B design
most straightforward and powerful within subject design (Baseline-treatment-baseline- treatment)
B-A-B design
begins with the application of the independent variable (treatment) after stable rates, return to baseline, if bx worsens, treatment is reintroduced
multiple treatment reversal design
experiments that use the reversal design to compare the effects to 2 or more experimental conditions to baseline and/or to one another
sequencing effects
effects of a subjects BX in a given condition that are a result of the subjects experience with a prior condition
NCR reversal design
deliver NCR on a fixed or variable time schedule independent of the subjects BX
DRO reversal design
control condition consists of delivering the event suspected of functioning as reinforcement following the emission of any BX other that then target BX.
DRI/DRA reversal
control condition- occurrence of a specified BX that is either incompatible or alternative BX to the target BX are immediately followed by the same consequence previously delivered as contingent reinforcement for the target BX
irreversibility
a level of BX observed in earlier phase cannot be reproduced even though the experimental conditions are the same as they were during an earlier phase
alternating treatments design
rapid alternation of 2 or more distinct treatments (IV) while there effects on the target behavior are measured.
- do not need stable baseline
- manipulated independent of responding
multiple treatment interference
the confounding effects of 1 treatment on the subjects BX being influenced by the effects of another treatment administered in the same study.
