This study used a novel rating task to investigate whether high-functioning individuals with autism spectrum disorder (ASD) have difficulties distinguishing essential from variable aspects of familiar events. Participants read stories about everyday events and judged how often central, variable, and inappropriate event-components normally occur in this type of situation. The ASD boys made significantly more errors than the typically developing boys in rating the occurrences of variable aspects. In both groups, ratings of variable aspects were age-related, but in the ASD boys, they were also related to theory of mind and weak coherence test scores, and to severity of autistic symptoms. Implications for the understanding of some repetitive behaviours, such as the tendency to adhere to inflexible routines, are discussed.
本研究使用一种新颖的评分任务来探究高功能自闭症谱系障碍（ASD）个体是否难以区分熟悉事件的本质和可变方面。参与者阅读关于日常事件的故事，并判断核心、可变和不适当的事件成分在这种情况下通常发生的频率。ASD 男孩在评定可变方面的发生频率时比典型发育男孩犯的错误明显更多。在两个组中，对可变方面的评分都与年龄有关，但在 ASD 男孩中，它们还与心理理论和弱连贯测试分数以及自闭症症状的严重程度有关。讨论了对某些重复行为的理解，例如坚持僵化常规的倾向。
