Technical definition, clinical ABA application, discriminative non-examples, and test-day traps for behavior analysis candidates.
An experimental design that begins with concurrent measurement of two or more behaviors in baseline condition, followed by the systematic application of the intervention to one behavior while maintaining baseline conditions on the other behaviors.
A BCBA staggers a functional communication training intervention across three settings: first math class (day 5), then reading class (day 12), and finally playground (day 20).
Withdrawing a successful self-injury intervention to return to baseline (this is an ABAB reversal design, often clinically hazardous).
Multiple baseline designs are preferred over reversal designs when target behaviors are irreversible (learned academic skills) or when returning to baseline would pose safety risks.
A behavior analyst is evaluating the effectiveness of a peer-modeling procedure to teach handwashing to a client. Which experimental design is most appropriate to demonstrate experimental control?
