In an attempt to control severe vomiting in a mentally retarded patient, shock was delivered after each stomach tension, a pre-vomiting response that consisted of an overt abdominal movement. Contingent shock resulted in an initial transitory increase followed by a decrease in rate of stomach tensions. There was a decrease in emitted vomitus, which resulted in a weight gain of the patient.
为了控制弱智患者的严重呕吐，在每次胃部紧张之前，都会进行电击，这是一种即将呕吐的反应，表现为明显的腹部运动。条件性电击导致初始的短暂增加，随后胃部紧张的速度下降。呕吐物的排放量减少，导致患者体重增加。
