A child is having temper tantrums at home, at school, and at his grandparents' house. After working with the parents for a while, the therapist believes that the child is being rewarded for his tantrums in each setting because his teacher, parents, and grandparents generally give him what he wants just to make him stop yelling. The therapist devises a plan to stop his tantrums but first implements the plan at home, then the following week at school, and finally at the grandparents' home several weeks later. From a research perspective, this is an example of
A) withdrawal method.
B) multiple baseline.
C) placebo control.
D) external validity.

Question

The therapist is implementing the plan gradually, first at home, then at school, and finally at the grandparents' house. This is an example of a multiple baseline design, where the intervention is implemented at different points in time or settings to see if the behavior changes consistently across all settings. The other options, withdrawal method, placebo control, and external validity, do not apply to this scenario.
