Motion Processing in ASD: From Low-Level Information to Higher-Level Social Information.

From birth, our visual system is sensitive to movement. Motion, as defined by any change in spatial position over time, is part of our daily lives and can refer to various visual information from elements of nature (like a tree swaying in the wind), objects (like a moving car), animals (like a running dog) or people (like two people dancing). Atypical motion processing, in particular for social and biological movement cues, could lead to difficulties in social interaction and communication, like those observed in Autism Spectrum Disorder (ASD). Extensive research has focused on coherent and biological motion processing in ASD, showing difficulties for both motion categories. Motion-related differences also emerge in several social contexts like emotion processing, joint attention, language acquisition, and body relationship with the environment. However, it remains unclear whether high-level difficulties stem from low-level processing issues or are specific to interpreting social cues. It appears that critical steps between low-level local cues processing and high-level biological/social contexts have not been studied. Adopting an approach encompassing a motion gradient from low to high levels could help identify when motion-related difficulties arise in ASD and which specific types or attributes of motion are most affected. This would offer a more comprehensive and integrated perspective on motion processing in ASD. This article is categorized under: Neuroscience > Cognition.
