In Experiment I, the effects of a verbal warning, such as is used in Overcorrection, delivered contingently on the stereotyped mouthing behavior of two autistic/retarded children were examined. A multiple baseline design across subjects was used. The results indicated that the mouthing of one child was reduced to a near-zero level and mouthing of the second child was moderately reduced. Appropriate toy play and inappropriate object manipulation failed to show systematic changes in occurrence when mouthing was decelerated. In Experiment II, the same subjects and experimental design were used to assess the effects of a positive practice Overcorrection procedure delivered contingent on mouthing behavior. Overcorrection reduced the mouthing of both subjects. There were no systematic changes in inappropriate object manipulation but one subject did demonstrate an increased occurrence of appropriate toy play. In addition, this subject often engaged in aggressive/escape behaviors during Overcorrection, suggesting that the procedure was aversive to him.
在实验一中，研究了一种言语警告（如在过度矫正中使用的）对两名自闭症/智力迟钝儿童刻板的张嘴行为的影响，该言语警告是依行为而定的。采用了跨受试者的多基线设计。结果表明，一名儿童的张嘴行为减少到接近零的水平，第二名儿童的张嘴行为也有适度减少。当张嘴行为减缓时，适当的玩具玩耍和不适当的物品操作在出现频率上未显示出系统性变化。在实验二中，使用相同的受试者和实验设计来评估依张嘴行为而定的积极练习过度矫正程序的效果。过度矫正减少了两名受试者的张嘴行为。不适当的物品操作没有系统性变化，但一名受试者确实表现出适当玩具玩耍的出现频率增加。此外，该受试者在过度矫正过程中经常出现攻击/逃避行为，这表明该程序对他来说是厌恶的。
