自闭症谱系障碍中的限制性和重复性行为已被概念化，以反映受损的执行功能。在本研究中，我们调查了6-17岁的自闭症谱系障碍儿童和非自闭症谱系障碍儿童在维度变化卡片排序任务中的表现，该任务在每次试验中都明确指出了排序规则。诊断组在第一次规则切换后的反应速度或混合与单一排序规则块的速度或准确性没有差异。然而，ASD组的表现比典型发育组明显更慢，整体准确性更低。此外，在ASD组中，较差的DCCS任务表现并不能预测更严重的自闭症症状。自闭症的执行功能障碍理论的影响进行了讨论。
Restricted and repetitive behaviors in autism spectrum disorders have been conceptualized to reflect impaired executive functions. In the present study, we investigated the performance of 6–17-year-old children with and without an autism spectrum disorder on a dimension-change card sort task that explicitly indicated sorting rules on every trial. Diagnostic groups did not differ in speed of responses after the first rule switch or in speed or accuracy on blocks with mixed versus single sort rules. However, performance of the ASD group was significantly slower and less accurate overall than the typically-developing group. Furthermore, within the ASD group, poorer DCCS task performance did not predict more severe autism symptoms. Implications for the executive dysfunction theory of autism are discussed.
