| summary | Interpersonal touch is one of the most effective nonverbal communication tools. Depending on the type of touch offered, a recipient may feel pleasant or unpleasant. Most of us effortlessly recognize the affective meaning of touch, whether we experience it first-hand or through the observation of others. However, individuals with autism spectrum disorder (ASD), primarily characterized by social impairments, often experience difficulties receiving, offering, and witnessing touch. Touch has important implications for daily social interactions and the formation of emotional bonds with others. Yet, the neural mechanisms underlying affective touch in neurotypical (NT) and ASD populations remain largely unknown. In this talk, I will present a line of research uncovering the neural underpinnings of touch-related socio-emotional deficits in ASD with advanced multi-methods neuroimaging and machine learning. NT adults show complex integration among social, emotional, and somatosensory regions when receiving and observing affective touch, and this integration is disrupted in ASD. This neural atypicality is also associated with the severity of touch aversion and poor social responsivity. Finally, I will discuss how the naturalistic neuroimaging paradigm can benefit an in-depth understanding of social perception in neurotypical and clinical populations. |
