We assessed the efficacy of several procedures for reducing the rate of eating responses during mealtime by three institutionalized mentally retarded clients. A time-based (15 s) response interruption procedure was implemented which resulted in little change in eating responses for 2 of 3 subjects. A spaced-responding DRL 15-s procedure resulted in decreases in eating responses to target levels only after a prompting procedure was added. Procedures were evaluated using a multiple baseline across subjects design with assessment of generalization to nontreated meals. A change in eating behavior during breakfast occurred only after direct training in the breakfast setting. Maintenance data were collected at 1- and 5-month follow-up periods.
我们评估了几种程序对三名机构收容的智力障碍患者在用餐时减少进食反应率的效果。实施了一种基于时间（15秒）的反应中断程序，结果3名受试者中有2名的进食反应几乎没有变化。一种间隔反应的15秒DRL程序只有在添加了提示程序后才使进食反应降至目标水平。使用跨受试者的多基线设计对程序进行评估，并评估对未治疗餐食的泛化情况。只有在早餐环境中进行直接训练后，早餐时的进食行为才发生改变。在1个月和5个月的随访期收集维持数据。
