ERP study examines how autistic traits affect semantic processing in neurotypical adults, suggesting a need for neurodiversity consideration.

The aim is to investigate how individual autistic traits influence the processing of scene-based semantics in neurotypical adults.
Event-related potentials (ERPs) were recorded during a scene-word congruency task with 30 neurotypical adults.
Participants were assessed for autistic traits using the Autism-Spectrum Quotient (AQ), along with measures of working memory and lexical proficiency.
Representational similarity analysis (RSA) was used to analyze neural response patterns across trials.
Participants exhibited an N400 congruency effect, with incongruent words causing greater integration costs (P<0.05).
The N400 effect magnitude increased with higher AQ scores, indicating heightened neural sensitivity to scene-category violations (P<0.01).
RSA analysis showed that higher AQ scores correlated with increased spatial consistency of neural responses, independent of word congruency.
