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. 5th Edition Task ListD-5 Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion). 6th Edition TCOD.7 Distinguish among reversal, multiple-baseline, multielement, and changing-criterion designs. Related Content Sequence effects A confounding effect on a subject’s behavior in a given condition that results from the subject’s experience with a previous condition.Repeated reversals design A variation of the reversal design that includes replication, in which responding is reversed to a level obtained in a previous condition by alternating between specific independent variables and baseline…Nonconcurrent multiple baseline across participants design A variation of the delayed multiple baseline design in which the baselines are so delayed that there is no overlap between them, like a series of AB designs across participants.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 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.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.NCR reversal technique A variation of the reversal design in which noncontingent reinforcement is used as the control condition and contrasted against contingent reinforcement. Responding is reversed to a level obtained in a…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.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.

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.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.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. Let's review a BCBA® mock exam question about reversal design and the nuances and concerns associated with this experimental setup. Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).The Most Utilized Experimental Design for Generalization Effects Learn what the most utilized experimental design is for generalization effect. PTB co-founder Dana Meller shares this design's key features and benefits, allowing us to assess the effects of an independent variable across various settings, subjects, and behaviors. Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).CON Artist Captured! Unmasking the CONfounding Variable of the Alternating Treatments Design PTB co-founder Dana Meller hones your experimental design skills with a focus on the alternating treatments design's confounding variable.
