Morphosyntactic and Semantic Processing related to the Location of Errors during Korean Sentence Comprehension using ERPs
This paper aims at investigating the cross-linguistic generality and intra-language specificity in processing morphosyntactic and semantic on-line processing in Korean often called head-final language using ERPs(Event-related Poentials). Before the current experiment, sub-classification for errors was firstly conducted into sentence-final-error(syntactic/semantic-final-error) and sentence-mid-error (syntactic/ semantic-mid-error) according as the same type of errors can be arisen in any loci of complement or predicate in Korean. Our experimental results shows that, as expected, P600(positive peak at about 600 ms after the stimulus onset) and N400(negative peak at about 400 ms after the stimulus onset) were observed in each error type respectively. However, specifically the centered activation area in sentence-final-error is moved into more posterior site from anterior position which is different from the topographic distribution occurring at sentence-mid -error. This finding suggests that the error-occurring position can be main factor having effect on error processing area as well as error types indexed with ERP characteristics such as latency or amplitude of the current component.
