Autistic adults exhibit typical sensitivity to changes in interpersonal distance

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Science

Background:

• Autism is characterized by visual processing differences impacting social perception.
• Autistic individuals often exhibit impaired face recognition.
• Dyadic social interactions may engage face-like visual processing.

Purpose of the Study:

• To investigate if autistic adults have impaired perception of interpersonal distance in social interactions.
• To compare visual processing of social interactions with face recognition abilities in autistic adults.

Main Methods:

• Participants completed distance change detection tasks for social interactions and control objects (grandfather clocks).
• Standardized measures assessed face recognition ability.
• Perceptual sensitivity to interpersonal distance was evaluated.

Main Results:

• Autistic and nonautistic observers demonstrated comparable sensitivity to changes in interpersonal distance during social interactions.
• Autistic observers exhibited significantly impaired face recognition compared to controls.
• No difference was found in judging distance changes for social interactions versus control objects.

Conclusions:

• Visual perception of interpersonal distance in social interactions is preserved in autistic adults.
• Face recognition deficits in autism do not necessarily extend to the perception of social interactions.
• Social vision may involve dissociable processing pathways for faces and interpersonal dynamics.
