患有自闭症谱系障碍（ASD）的个体经常经历，描述和表现出不寻常的感觉和注意力模式。这些异常被假设是由于过度兴奋和随之而来的过度集中的注意力。ASD患者的父母在三个领域，“感觉过度反应”，“感觉反应不足”和“感觉寻求行为”，感官配置文件，本研究开发的103项评级量表的扩展版本的项目。父母还评估了症状的严重程度，过度选择性注意力和特殊的记忆力，并完成了葡萄园适应行为量表。在222名受试者中，144名有完整的数据。聚类分析显示，43%的样本具有预测的过度集中的感觉和注意力模式，包括过度反应、持续的行为和兴趣、过度集中的注意力和异常的记忆力。这一模式在10%中引人注目。过度反应和过度聚焦的神经学基础与过度觉醒假说有关。值得注意的是，它在ASD人群中相当普遍。
Individuals with autistic spectrum disorders (ASDs) often experience, describe and exhibit unusual patterns of sensation and attention. These anomalies have been hypothesized to result from overarousal and consequent overfocused attention. Parents of individuals with ASD rated items in three domains, 'sensory overreactivity', 'sensory underreactivity' and 'sensory seeking behaviors', of an expanded version of the Sensory Profile, a 103-item rating scale developed for the present study. Parents also rated symptom severity, overselective attention and exceptional memory, and completed the Vineland Adaptive Behavior Scales. Of 222 rated subjects, 144 had complete data. Cluster analysis showed the predicted overfocused pattern of sensation and attention, comprising overreactivity, perseverative behavior and interests, overfocused attention and exceptional memory in 43 percent of this sample. This pattern was striking in 10 percent. The neurological basis of overreactivity and overfocusing is discussed in relation to the overarousal hypothesis. Attention is drawn to its considerable prevalence in the ASD population.
