Autonomic versus perceptual accounts for tactile hypersensitivity in autism spectrum disorder

Abstract Tactile atypicality in individuals with autism spectrum disorder (ASD) has harmful effects on their everyday lives including social interactions. However, whether tactile atypicality in ASD reflects perceptual and/or autonomic processes is unknown. Here, we show that adults with ASD have hy...
