Disrupted integration of exteroceptive and interoceptive signaling in autism spectrum disorder

Abstract

IntroductionAutism Spectrum Disorders (ASD) are defined by core deficits in social communication and interaction, as well as by the presence of repetitive patterns of behavior and restricted interests [American Psychiatric Association, ]. Further, clinicians and researchers are increasingly noting abnormalities in sensory processing in these patients [Baum, Stevenson, & Wallace, ; Iarocci & McDonald, ; Le Couteur et al., ; Marco, Hinkley, Hill, & Nagarajan, ]—observations that have led to the incorporation of sensory and perceptual abnormalities [most often expressed as either hypo‐ or hyper‐sensitivity to sensory stimuli; Baranek, David, Poe, Stone, & Watson, ] as a diagnostic feature for ASD in the DSM‐V [American Psychiatric Association, ].In addition to differences in responsiveness to stimuli presented within the individual senses, a number of recent reports have highlighted that individuals with ASD may also exhibit deficits in tasks requiring integration or utilization of information across the different sensory modalities [i.e., multisensory tasks; see Brandwein et al., ; Foxe et al., ; Smith & Bennetto, 2007; Stevenson et al., ; Woynaroski et al., ].
