Reversal design Any experimental design in which responding is reversed to a level obtained in a previous condition by alternating between specific independent variables and baseline conditions. 5th Edition Task ListD-5 Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion). 6th Edition TCOD.9 Apply single-case experimental designs.

Therefore, it cannot return to a baseline level of responding when an independent variable is removed.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. Dana Do's: A Trick to Help Dissect BCBA® Exam Questions on Experimental Designs Experimental design tends to trip lots of people up. Here's an exam trick from Dana Meller that will help you breaking down questions on the exam.Let's Break Down a BCBA® Mock Exam Question: Ethical Considerations in Experimental Design Test your understanding of ethical considerations in experimental designs with PTB co-founder Dana Meller.
