Following a functional analysis showing that destructive behavior was reinforced by escape, we altered the aversiveness of task demands by interspersing easy and difficult tasks and by presenting a corrective prompt as an antecedent event the next time a previously failed item was presented; this procedure was compared with one in which the corrective prompt was provided as an immediate consequence. Results of a reversal design showed that the antecedent prompt acted as an establishing operation and reduced destructive behavior to zero.
在进行功能分析表明破坏性行为因逃避而得到强化后，我们通过穿插简单和困难任务以及在下次呈现之前失败的项目时将纠正提示作为先行事件呈现，来改变任务要求的厌恶程度；将此程序与将纠正提示作为即时后果提供的程序进行比较。反转设计的结果表明，先行提示起到了建立操作的作用，并将破坏性行为减少到零。
