The A-B design involves measuring a behavior during a baseline period (A), introducing an intervention (B), and then measuring the behavior again during a post-intervention phase. This design is useful for evaluating the effectiveness of an intervention by comparing the behavior before and after implementation. The other options (changing criterion design, group research design, A-B-A design) involve different components, such as multiple intervention conditions or alternations between intervention and non-intervention periods.
