In order to discover whether there is an effect of self-control training a multiple baseline study was conducted. The study consisted of three African American children who lived in foster care, where two of the children received no medication for ADHD while one did. The experiment consisted of 3 baselines: natural baseline, choice baseline, and a self-control baseline. In the natural baseline, the three children were separated from each other and each child chose a food related reinforcer, which was placed on the table in front of each child. Each child was told to wait as long as possible before eating and once they could not wait any longer they were able to eat the food. The time that each child waited was timed and recorded, and was used as a comparison later on in the self-control training baseline. In the choice baseline each child was given an option of receiving a smaller reward immediately, or receiving a larger reward but having to wait for it. The amount of time the participant had to wait if they chose the larger reward was six times as long as their natural baseline. The self control training was similar to the choice baseline in the sense that participants were asked if they want their small reward now or a larger reward after they played a game. If the participant chose the larger reward they would play a puzzle game for four session. The time that each session took would increase by x seconds until all four sessions were completed and the child received their reward.
