This study examined the relationship between repetitive behaviors and sensory processing issues in school-aged children with high functioning autism (HFA). Children with HFA (N = 61) were compared to healthy, typical controls (N = 64) to determine the relationship between these behavioral classes and to examine whether executive dysfunction explained any relationship between the variables. Particular types of repetitive behavior (i.e., stereotypy and compulsions) were related to sensory features in autism; however, executive deficits were only correlated with repetitive behavior. This finding suggests that executive dysfunction is not the shared neurocognitive mechanism that accounts for the relationship between restricted, repetitive behaviors and aberrant sensory features in HFA. Group status, younger chronological age, presence of sensory processing issues, and difficulties with behavior regulation predicted the presence of repetitive behaviors in the HFA group.
本研究考察了高功能自闭症（HFA）学龄儿童的重复行为与感觉加工问题之间的关系。将HFA儿童（N = 61）与健康的典型对照组（N = 64）进行比较，以确定这些行为类别之间的关系，并检验执行功能障碍是否能解释变量之间的任何关系。特定类型的重复行为（即刻板行为和强迫行为）与自闭症中的感觉特征有关；然而，执行功能缺陷仅与重复行为相关。这一发现表明，执行功能障碍并非解释HFA中受限的重复行为与异常感觉特征之间关系的共同神经认知机制。组别状态、较小的实际年龄、感觉加工问题的存在以及行为调节困难可预测HFA组中重复行为的存在。
