| The present study investigated whether the phonological mismatch-associated ERP effects are modulated by lexical status of the targets during spoken word recognition in Mandarin Chinese. Utilizing a unimodal auditory priming paradigm, the phonological similarities of the first syllables between the prime and target words/pseudowords were manipulated, with the same targets preceded by the identical, unrelated, or cohort primes (i.e., sharing the same initial syllables as the targets). An enhanced phonological P2 component between 200 and 270 ms post-target onset was elicited by word-initial mismatch in the unrelated conditions, and a centro-parietally distributed Late N400 was elicited in the cohort and unrelated conditions. Neither the P2 nor Late N400 was modulated by the lexicality of the targets. The effect of lexical status was only found for the Early N400, indicating the presence of concurrent phonological and semantic processes in the 350-450 ms time window. The current study provided further evidence for that the phonological P2 is an index of phonological processing load at the pre-lexical processing stage during spoken word recognition and is not modulated by semantic processes. |
