Julie is a BCBA working with her client Jamel on reducing his physical aggression. She implements a differential reinforcement for other behavior (DRO) procedure and measures its effectiveness at reducing Jamel’s total count per week of physical aggression. Julie uses preferred edible items such as peanuts and hard candy for every 30 minutes in which Jamel does not engage in physical aggression. When running the DRO procedure during one of the weeks, Jamel came into the clinic with a severe toothache. Another week, Jamel’s grandmother, who always sneaks him pieces of candy when no one is looking as a special treat, comes to visit from out of town and stays with his family at their house for a few days. Which of the following is the independent variable in this scenario?
