Language comprehension requires the processing of both linguistic and extra-linguistic information, such as syntax, semantics, and pragmatic information. Previous studies have systematically examined the interplay between syntactic and semantic processing. However, there is a lack of data on how pragmatic processing proceeds and its interaction with semantic processing. Using event-related potentials (ERPs), the present study manipulated the semantic coherence of a verb phrase (VP) and the respect consistency of the object noun phrase in the VP, resulting in four types of critical sentences. Participants read 160 critical Chinese sentences and 220 filler sentences. After electroencephalogram recordings, they completed the Autism Quotient Communication (AQ-Comm) subscale and a sentence acceptability rating task. The ERP results showed that respect violation elicited a larger N400 response and a late negative activity in the pragmatically less-skilled subgroup (as indexed by higher scores on the AQ-Comm subscale). In contrast, respect violation elicited a P600 response in the pragmatically skilled subgroup (as indexed by lower scores on the AQ-Comm subscale). The double violation condition elicited an ERP pattern that was similar to that of the semantic violation condition in both subgroups, suggesting that respect violation effects were present only when the VP was semantically coherent. These results suggest that semantic violation can preclude readers from engaging in pragmatic inferencing, regardless of the participants' pragmatic skills. Strategies for resolving respect violation and corresponding brain activities vary according to participants' pragmatic abilities.
