Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).
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.

PTB co-founder Dana Meller hones your experimental design skills with a focus on the alternating treatments design’s confounding variable.
Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).
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

Test your Experimental Design skills with PTB co-founder Dana Meller as she reviews and breaks down a mock exam question about reversal design variations that display only one reversal. Included is a description of A-B-A, B-A-B, and A-B-A-B reversal designs.
Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).
Test your Experimental Design skills with a breakdown of a BCBA® mock exam question about the identification of a three-phase experimental design. Included is a detailed comparison between four different reversal designs: ABC reversal, ABA reversal, BAB reversal, and ABAB reversal. As a bonus, Dana also provides examples of instances in which each of the reversal designs would be implemented.
