Existing evidence indicates that atypical sensory reactivity is a core characteristic of autism, and has been linked to both anxiety (and its putative infant precursor of fearfulness) and repetitive behaviours. However, most work has used cross-sectional designs and not considered the differential roles of hyperreactivity and hyporeactivity to sensory inputs, and is thus limited in specificity.

感觉过度反应和反应低下在理解婴儿恐惧和新出现的自闭症特征中的作用

现有证据表明，非典型的感觉反应是自闭症的核心特征，并且与焦虑（及其假定的婴儿恐惧前兆）和重复行为有关。然而，大多数工作都使用横截面设计，并没有考虑高反应性和低反应性对感觉输入的不同作用，因此在特异性上受到限制。
