Covert food stealing is common among individuals with Prader-Willi syndrome. We found that verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decrease the food stealing of a girl with Prader-Willi syndrome. Warning stimuli were then used to help her discriminate between permitted and prohibited foods during sessions in which food stealing was not directly observed. This procedure resulted in decreases in food stealing from containers labeled with the warning stimuli.
隐性偷食在普拉德-威利综合征患者中很常见。我们发现，在食用禁食时给予口头斥责足以减少一名普拉德-威利综合征女孩的偷食行为。随后，在未直接观察到偷食行为的时段，使用警示刺激来帮助她区分允许食用和禁止食用的食物。这一程序使得从标有警示刺激的容器中偷食的行为减少。
