Four children with autism received opportunities to choose among several preferred stimuli either immediately before or after task responding. The response requirement for reinforcement systematically increased within each session. Two children engaged in higher levels of responding when reinforcement choice was provided as an antecedent to task completion, and 3 of the 4 children showed a preference for the antecedent choice condition.
四名自闭症儿童有机会在任务反应之前或之后从几种偏好刺激中进行选择。每次训练中强化的反应要求会系统地增加。当强化选择作为任务完成的前提条件时，两名儿童的反应水平更高，并且四名儿童中有三名表现出对前提选择条件的偏好。
