Final answer:
Dawn Tin designed a study using a withdrawal design to evaluate for a functional relation. Each participant went through the baseline and intervention conditions twice to compare the behavior. This design allows for assessing whether the intervention has a functional relation with the outcome.
Step-by-step explanation:
In Dawn Tin's study using a withdrawal design, each participant went through the baseline condition twice and the intervention condition twice. This design allows researchers to assess whether the intervention has a functional relation with the outcome. By exposing participants to both conditions multiple times, the study can evaluate if the observed change in behavior is a result of the intervention or other factors.
For example, if a participant shows improvement in problem-solving skills only during the intervention condition and not during the baseline condition, it suggests a functional relation between the intervention and the outcome. On the other hand, if the improvement is observed consistently across both conditions, it may indicate factors unrelated to the intervention. In this study with three participants, Dawn programmed for opportunities for careful comparison of the behavior across the baseline and intervention conditions for each participant to evaluate the functional relation.
