Sixty-eight participants with severe mental retardation participated in a study of representational matching to sample. Participants were asked to match objects to identical objects, line drawings, miniature objects (icons), pantomimes, and spoken names. Participants who were successful in these matching tasks also experienced delayed matching tasks. Participants differed in their expressive communication and comparisons were made between symbolic (speaking) individuals, distal gesture users, and contact gesture users. Contact gesture users were significantly worse on identical matching to sample tasks than other participants. Mean scores on matching objects to line drawings were significantly better than mean scores on other matching tasks. In delayed matching, however, scores for matching objects to spoken names were significantly better than other tasks. The implications of these results for learning to use an augmentative communication device are discussed.
68名重度智力障碍参与者参与了一项样本表征匹配研究。参与者被要求将物体与相同物体、线条画、微型物体（图标）、手势和口语名称进行匹配。在这些匹配任务中成功的参与者还经历了延迟匹配任务。参与者在表达交流方面存在差异，并对有语言能力的个体、使用远距离手势的个体和使用接触性手势的个体进行了比较。在样本相同匹配任务中，使用接触性手势的个体明显比其他参与者表现差。将物体与线条画进行匹配的平均得分明显高于其他匹配任务的平均得分。然而，在延迟匹配中，将物体与口语名称进行匹配的得分明显高于其他任务。本文讨论了这些结果对学习使用辅助沟通设备的启示。
