Undesirable mealtime behaviors of a hospital cottage of retardates were reduced by contingent timeout procedures applied by ward personnel successively to one undesirable behavior after another, in a multiple baseline design. In some cases the timeout procedure was to remove the subject from the room until the meal was finished; in other cases (depending on the health of the child and the initial rate of the behavior to be reduced), timeout consisted of a 15-sec removal of the child's meal tray. Undesirable behaviors were defined as stealing, using fingers inappropriately, messy use of utensils, and pigging (eating directly with mouth or eating spilled food). Timeout was applied to these behaviors in that order, and in each case led to a marked and useful reduction in the behavior throughout the group. As these undesirable behaviors were reduced, more appropriate mealtime behaviors emerged: as inappropriate use of fingers declined (under contingent timeout), messy utensil behavior increased; later, as messy utensil behavior declined (under contingent timeout), a defined category of neat utensil behavior increased. Weights of the subjects were monitored steadily throughout the study and showed essentially no change.
通过连续的随机关联时间限制程序，在一个多重基线设计中，将医院疗养所智障患者的不良进餐行为逐渐减少。在某些情况下，时间限制程序是将受试者从房间中移出，直到用餐结束；在其他情况下（取决于孩子的健康状况和要减少的行为的初始速度），时间限制包括将孩子的餐盘移除 15 秒。不良行为被定义为偷窃、不恰当地使用手指、餐具使用混乱以及狼吞虎咽（直接用嘴吃或吃溢出的食物）。时间限制按此顺序适用于这些行为，在每种情况下，都导致整个群体的行为明显且有用地减少。随着这些不良行为的减少，更适当的进餐行为出现了：随着不恰当地使用手指的行为减少（在随机关联时间限制下），餐具使用混乱的行为增加；后来，随着餐具使用混乱的行为减少（在随机关联时间限制下），一个定义明确的整洁餐具行为类别增加了。在整个研究过程中，对受试者的体重进行了持续监测，基本没有变化。
