BAB reversal design
A three-phase variation of the reversal design that begins with the treatment phase first, followed by the baseline phase, after which responding is reversed to a level obtained in the… Read more
D.7 Distinguish among reversal, multiple-baseline, multielement, and changing-criterion designs.
Changing criterion design
An experimental design in which an initial baseline phase is followed by a series of treatment phases consisting of successive, stepwise, and gradually changing criteria for which reinforcement or punishment

Dana Do’s: Can Changing Criterion Design be Used to Evaluate Shaping Programs?
Can can a changing criterion design be used to evaluate shaping programs? Well, PTB founder Dana Meller says, it depends.

Delayed multiple baseline design
A variation of the multiple baseline design in which all of the baselines do not begin at the same time, instead additional participant baselines are added to the study as
DRO/DRI/DRA reversal technique
A variation of the reversal design in which DRO, DRA, or DRI are used as the control condition and contrasted against each other. Responding is reversed to a level obtained
Irreversibility
A behavior for which the effects of treatment cannot be undone. Therefore, it cannot return to a baseline level of responding when an independent variable is removed.
Multielement design
An experimental design in which two or more independent variables are presented in rapidly alternating succession, and the differential effects of each independent variable on the target behavior are measured.
Multiple baseline design
An experimental design in which the effect of one independent variable is measured and evaluated within and across combinations of two or more subjects, behaviors, or settings.
Multiple probe design
A variation of the multiple baseline design that uses intermittent measurement or probes instead of consecutive measures to evaluate the effect of one independent variable within and across combinations of
Multiple treatment (reversal) design
A variation of the reversal design in which multiple treatments are alternated in different phases and compared to baseline and/or each other.
Multiple treatment interference
In an experimental design that requires the implementation of more than one independent variable to one subject, the outcome of one treatment may be influenced by the effect of another.
