Brief summary
Social cognition refers to the mental processes involved in social interactions, including social perception, motivation, communication, emotion recognition, and theory of mind. Face perception plays a key role in children's social development, but children with Autism Spectrum Disorder (ASD) tend to look less at social stimuli, especially faces, than typically developing (TD) peers. Eye-tracking studies highlight these visual exploration differences, linked to difficulties in joint attention, emotion recognition, and theory of mind, as well as in executive and memory functions. Standard diagnostic tests often require active participation and sufficient language, which makes assessment challenging for children with ASD and additional cognitive or language impairments. This research project investigates how visual activity supports social cognition depending on cognitive and language levels, hypothesizing that eye-tracking can provide useful indicators for ASD screening and diagnosis.
