Chapter 9 Flashcards
Multiple Baseline 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 and gradually changing criteria for reinforcement or punishment. Experimental control is evidenced by the extent the level of responding changes to conform to each new criterion.
Delayed Multiple Baseline Design
A variation of the multiple baseline design in which an initial baseline, and perhaps intervention, are begun for one behavior (or setting, or subject), and subsequent baselines for additional behaviors are begun in a staggered or delayed fashion.
Multiple Baseline Across Behaviors Design
A multiple baseline design in which the treatment variable is applied to two or more different behaviors of the same subject in the same setting.
Multiple Baseline Across Settings Design
A multiple base line design in which the treatment variable is applied to the same behavior of the same subject across two or more different settings, situations, or time periods.
Multiple Baseline Across Subjects Design
A multiple baseline design in which the treatment variable is applied to the same behavior of two or more subjects (or groups) in the same setting.
Multiple Baseline Design
An experimental design that begins with the concurrent measurement of two or more behaviors in a baseline condition, followed by the application of the treatment variable to one of the behaviors while baseline conditions remain in effect for the other behavior(s). After maximum change has been noted in the first behavior, the treatment variable is applied in sequential fashion to each of the other behaviors in the design. Experimental control is demonstrated if each behavior shows similar changes when, and only when, the treatment variable is introduced.
Multiple Probe Design
A variation of the multiple baseline design that features intermit-tent measures, or probes, during baseline. It is used to evaluate the effects of instruction on skill sequences in which it is unlikely that the subject can improve performance on later steps in the sequence before learning prior steps.
Nonconcurrent Multiple Baseline Across Participants Design
An experimental design that consists of of a related series of A-B design sequence conducted across participants at different points in time; often used to assess treatment effects when concurrent measurement of participants’ behavior can not be measured is not possible.
Range-Bound Changing Criterion Design
A variation of the changing criterion design in which each intervention sub-phase includes a lower and an upper criterion within which the participant is expected to perform.
