A psychologist is working with the parents of four children who exhibit violent behaviors toward each other. The parents have been instructed to record the number of these behaviors each child exhibits in the predinner hour for 1 week. The parents then begin using a positive reinforcement technique to shape the behavior of the youngest child while continuing to record violent behaviors. The recording continues and the technique is used on one additional child each week. By the end of 6 weeks, there is a significant decrease in violent behaviors for each of the children. Which type of design is this?
