How would you use an alternating treatment design to determine which type of exercise routine is most effective for Susan?

Applying Single-Subject Research Methodologies

For this assignment:

1. Read through these scenarios. Each scenario corresponds to one of the single-subject research methods commonly employed by behavior analysts.
Scenario 1 – Multiple Baseline Design:

Suppose you have two preschool students who engage in disruptive behavior in the classroom, and you want to evaluate an intervention to decrease the disruptive behavior.

Describe how you would use a multiple baseline across subjects design to evaluate the intervention in this scenario.
Scenario 2 – Withdrawal Design: Juan acts out in class and makes jokes at inappropriate times. The teacher believes that he is exhibiting this behavior to gain her attention. How would you use a withdrawal design to determine if, in fact, Juan is trying to gain the teacher’s attention?
Scenario 3 – Alternative Treatments Design: Susan is trying to develop an exercise routine for herself. She wants to determine if she does better sticking to a routine if she participates regularly in a structured class, or if she exercises alone using equipment she has in the home, like workout videos, weight bench, bicycle, et cetera. How would you use an alternating treatment design to determine which type of exercise routine is most effective for Susan?
Scenario 4 – Changing Criterion Design: Bob is a heavy smoker. He has chosen to try to stop smoking gradually instead of cold turkey. He has set a quit date for the end of the month. How would Bob use a changing criterion design to help track his progress as he attempts to quit smoking.
