title: Operant conditioning of human anal sphincter pressure.
abstract: Anal sphincter pressure in a 13-yr-old encopretic boy was modified by reinforcing increases in pressure exerted on a fluid-filled balloon inserted into the rectum. It was found that pressure changes were a function of the reinforcement schedule and that baseline levels (resting pressure) during extinction conditions tended to increase throughout the experiment.
