本研究旨在验证两种不同的假设一种是象征性假设，另一种是执行功能假设，这两种假设都是关于先前自闭症研究中发现的模仿和哑剧缺陷的。研究对象为17名患有自闭症谱系障碍的青少年高功能受试者和15名在实足年龄和言语智商上相匹配的临床对照受试者。在面部和手动模仿任务中操纵意义和序列。在哑剧和控制任务中，序列被操纵。识别记忆和运动控制任务与实验任务相匹配。研究结果没有为符号缺陷假说提供支持;意义有助于而不是阻碍自闭症患者的表现。部分支持执行缺陷hypothesis. There是没有组间差异的运动控制任务，和一些记忆控制任务，反对赤字的运动启动，基本的运动协调，或视觉识别记忆。
A study was designed to test 2 alternative hypotheses-a symbolic hypothesis and an executive function hypothesis-for the imitation and pantomime deficits found in previous studies of autism. The subjects were 17 adolescent high-functioning subjects with autism spectrum disorders and 15 clinical comparison subjects who were matched on chronological age and verbal IQ. Meaning and sequence were manipulated in facial and manual imitation tasks. Sequence was manipulated in the pantomime and control tasks. Recognition memory and motor control tasks were matched to the experimental tasks. The results provided no support for the symbolic deficit hypothesis; meaning aided rather than hindered the performance of the group with autism. Partial support for the executive deficit hypothesis was found. There were no group differences on motor control tasks, and few on the memory control tasks, arguing against deficits in motor initiation, basic motor coordination, or visual recognition memory.
