Final answer:
Withdrawal designs in experimental single-subject designs involve applying a treatment or intervention to an individual and then withdrawing it to assess the effect on their behavior or outcomes.
Step-by-step explanation:
Withdrawal designs are used in experimental single-subject designs to assess the effect of removing a treatment or intervention that has been applied to an individual. In these designs, the treatment is applied for a period of time, and then it is withdrawn to assess the impact on the individual's behavior or outcomes. This allows researchers to determine whether the treatment is responsible for the observed changes.
For example, in a study on the effectiveness of a behavioral intervention for reducing problem behaviors in a child with autism, the treatment may be applied for several weeks, and then withdrawn to see if the problem behaviors return.
