The effects of choice and no choice of reinforcer on the response rates of 3 children with autism were compared across single-operant and concurrent-schedule procedures. No consistent differences in responding between choice and no-choice components emerged during single-operant phases. During the concurrent-schedule phases, however, all participants had substantially higher rates of responding to the button that led to a choice among reinforcers than to the button that did not lead to choice.
通过单操作和并发程序，比较了强化物选择和无选择对3名自闭症儿童反应率的影响。在单操作阶段，选择和无选择成分之间的反应没有出现一致的差异。然而，在并发程序阶段，所有参与者对导致强化物选择的按钮的反应率都大大高于对不导致选择的按钮的反应率。
