Explain the guidelines Ledford & Gast (2019) suggest for using an A-B-A-B design. Then provide a short discussion of internal and external validity issues for this specific design to include a discussion of the advantages and disadvantages of the design. Finally, identify a hypothetical target behavior (dependent variable) for change and a possible intervention (independent variable). The target behavior should be a behavior you want to increase and the intervention should be some form of reinforcement procedure (i.e., differential reinforcement). Provide a brief scenario and rationale for the behavior change plan. Make sure the behavior identified is measurable and observable.
