Greater interpersonal distance in adults with autism

Area of Science:

• Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Social interactions rely on appropriate interpersonal distance.
• Individuals with autism spectrum disorder (ASD) often exhibit atypical social behaviors, including challenges with interpersonal distance.
• Previous anecdotal evidence suggests autistic individuals maintain different personal space boundaries.

Purpose of the Study:

• To systematically measure interpersonal distance in autistic adults.
• To investigate how autistic individuals calibrate personal space during social interactions.
• To compare interpersonal distance in autistic and neurotypical adults using a controlled virtual reality environment.

Main Methods:

• Utilized immersive virtual reality (IVR) to simulate naturalistic social interactions.
• Participants (autistic and neurotypical adults) approached and were approached by a virtual avatar.
• Measured interpersonal distance in active (approaching) and passive (being approached) conditions.

Main Results:

• Autistic adults maintained significantly greater interpersonal distance compared to neurotypical adults.
• The difference in interpersonal distance between active and passive conditions was smaller in autistic adults.
• Higher autism-related traits correlated with greater interpersonal distance across all participants.

Conclusions:

• Provides systematic evidence for increased interpersonal distance in autistic adults.
• Suggests differences in spatial regulation strategies during social interactions in autism.
• Findings can inform environmental design for inclusive shared spaces for autistic individuals.
