Lay abstract Atypical sensory behaviors are common in autism spectrum disorder and developmental delay. To date, it remains unclear whether sensory abnormalities are specific to autism spectrum disorder or reflect a broader pattern related to developmental disability in general. In this study, brain electrical responses to rarely occurring (novel) sounds and clinically evaluated sensory response patterns were investigated in 28 children with autism spectrum disorder, 17 children with developmental delay, and 39 typically developing children (typical development). Results showed that brain responses related to attention orienting were smaller in autism spectrum disorder relative to both developmental delay and typical development, but brain responses related to sensory processing were smaller in both autism spectrum disorder and developmental delay relative to typical development. The smaller brain responses were related to more severe sensory abnormalities across children with autism spectrum disorder and developmental delay. Thus, although brain attentional abnormalities may be unique to autism spectrum disorder, brain sensory abnormalities appear across developmental delay and are associated with atypical sensory behaviors.
