Impaired social concept processing in persons with autistic-like traits

Area of Science:

• Cognitive Science
• Neuroscience
• Developmental Psychology

Background:

• Situated models propose social concepts stem from interpersonal interactions.
• Experimental evidence, especially in individuals with limited social experience, is scarce.
• Autism spectrum disorder is characterized by social interaction differences.

Purpose of the Study:

• To experimentally investigate the link between interpersonal experience and social concept comprehension.
• To assess text-level social and non-social concept understanding in individuals with and without autistic traits.
• To explore the relationship between social concept processing and autistic traits.

Main Methods:

• Participants with and without autistic-like traits read social and non-social texts.
• Comprehension of social and non-social concepts was assessed via questionnaires.
• Behavioral outcomes were compared, classified, and correlated with autism measures.

Main Results:

• Individuals with autistic-like traits exhibited specific difficulties with text-level social concepts.
• Social concept comprehension was the sole significant classifier between groups, independent of cognitive factors.
• Poorer social concept understanding correlated with higher autistic trait severity.

Conclusions:

• Reduced interpersonal experience appears to selectively impair text-level social concept processing.
• Findings provide empirical support for situated models of social semantics.
• Social interaction is crucial for developing and understanding social concepts.
