This study aimed to investigate whether long-term domain-specific sport experience influences general action-related lexical semantic processing. Wushu (martial arts) athletes and non-athletes were asked to complete a lexical decision task in which nouns served as targets primed by general action-related or action-unrelated verbs. Event-related potential (ERP) results showed that target nouns primed by action-related verbs elicited reduced N400s compared to those primed by action- unrelated verbs for both groups. Moreover, target nouns primed by action-related verbs elicited larger late positive components (LPCs) than those primed by action-unrelated verbs only for wushu athletes and not for non-athletes. These results suggest that long-term domain-specific sport experience facilitates general action-related lexical semantic processing and support an association between the sensory-motor system and language comprehension.
