The multisensory base of bodily coupling in faceto- face social interactions: Contrasting the case of autism with the Möbius syndrome

Abstract

The perennial question of how we understand others' emotions and mental states has undertaken an "interactive turn," emphasizing the crucial role of low-level bodily coupling and second-personal engagements with others as opposed to the individualistic procedure of mental state attribution or "mindreading." This raises the important question of what counts as foundational for socio-emotional understanding: high-level mentalistic abilities, low-level bodily coupling, or an integrative combination of both? Recent findings on facebased emotion-recognition in individuals with Möbius syndrome (MS) - a rare form of congenital facial paralysis which prevents facial mimicry - cast doubt on the idea that bodily coupling is the foundational component for socio-emotional understanding. Here we argue that the MS case does not pose a threat to the idea that low-level bodily coupling processes are foundational for social cognition. Rather, despite their lack of automatic facial mirroring, MS patients might benefit from sparedmultisensory integration processing which allows them to establish alternative channels of bodily coupling via different sensory modalities. We contrast MS- and autistic persons' lack of automatic facial mimicry and argue that this comparison might help us to shed light on the constitutive and foundational role of low-level bodily coupling for socioemotional understanding.
