为探讨自闭症儿童模仿的特异性障碍，比较了22例脆性X综合征(FXS)伴与不伴自闭症儿童的模仿能力。根据之前的研究，我们预测患有FXS和自闭症的儿童在无意义的模仿任务上会有明显更大的困难。在控制了完整的智商和年龄后，两组的总体模仿准确率得分没有差异，但错误模式分析显示，患有FXS和自闭症的儿童比对照组犯了更多的摸索错误和额外的动作。这些错误模式与动作产生系统缺陷在自闭症总体模仿缺陷中起重要作用的假设一致，至少在FXS儿童中是这样。
To address the specific impairment of imitation in autism, the imitation abilities of 22 children with fragile X syndrome (FXS) with and without autism were compared. Based on previous research, we predicted that children with FXS and autism would have significantly more difficulty with non-meaningful imitation tasks. After controlling for full-scale IQ and age, the groups did not differ in their overall imitation accuracy scores, but analysis of error patterns revealed that children with FXS and autism made more groping errors and additional movements than the comparison group. These error patterns are consistent with the hypothesis that an action production system deficit plays an important role in the overall imitation deficit in autism, at least in children with FXS.
