Fifty-one severely retarded adults were taught a difficult visual discrimination in an assembly task by one of three training techniques: (a) adding and reducing large cue differences on the relevant-shape dimension; (b) adding and fading a redundant-color dimension; or (c) a combination of the two techniques. There were significant differences between training conditions in both trials- and errors-to-criterion performance. These were attributed to differential establishment of stimulus control in the first phase of training, with the combined procedure being the most effective, the color coding/fading next, and the relevant-dimension cue-disparity method the least powerful. These results demonstrated that substantial differences may exist in the efficacy of various vocational-skill training procedures involving manipulation of stimulus features.
51名重度智障成年人通过以下三种训练技术之一，在一项装配任务中学习一种难度较大的视觉辨别能力：(a) 在相关形状维度上增加和减少较大的线索差异；(b) 添加并逐渐消除一个多余的颜色维度；(c) 两种技术的组合。在达到标准的试验次数和错误次数方面，训练条件之间存在显著差异。这些差异归因于训练第一阶段刺激控制的不同建立方式，其中组合程序最有效，颜色编码/消退其次，相关维度线索差异法效果最差。这些结果表明，在涉及刺激特征操作的各种职业技能训练程序的效果方面，可能存在很大差异。
