A researcher plans to use the reversibility of the desired target behavior as evidence of a treatment effect. She does not want the subject to leave the experiment showing the original, undesirable behavior. Which one of the following designs would be most appropriate for this study?
A) A-B-A design
B) A-B-A-B design
C) interaction design
D) multiple-baseline design

The A-B-A-B design is the most appropriate for this study as it allows for the replication of the initial baseline (A) after the treatment is removed (B), and then introduces the treatment again (B), followed by the replication of the initial baseline (A). This design enables the researcher to observe whether the target behavior is reversible and whether the treatment has a lasting effect. By including a second baseline and treatment phase, it also allows the researcher to establish whether any changes in the behavior are due to the treatment or other factors.
