A student and his problems were pin-pointed, recorded, and changed. The first 3 wk. were used to establish a base rate. S defecated in class, once every few days. After he was programmed with reinforcers (charting and coupons toward book purchases), he may have had one accident, only, for the remainder of the school year (8 wk.). Follow-up through the seventh month of the next school year (the time of this writing) indicates one accident only. During this 7-mo. period, he was not programmed with book coupons or any other specific reinforcer. He had internalized a previous external model of control.
