한국어 문장이해에서 다의어와 동음이의어의 표상과 처리 : ERP 연구

This study iNvestigated the differeNces of polysemy aNd homoNym duriNg oNliNe seNteNce compreheNsioN iN KoreaN. UsiNg the ERP paradigm, we maNipulated the coNteNt of coNtext to be biased iN a way that the seNses of polysemy aNd homoNym were to be domiNaNt, subdomiNaNt or Neutral. IN each coNtext coNditioN, we also maNipulated the meaNiNg of the seNteNce-fiNal verb was to be coNgrueNt or iNcoNgrueNt to the coNtext. At the verb regioN, we observed the coNgrueNcy effect emerged as the N400 aNd the P600 iN the processiNg of homoNym but appeared as the P600 iN that of polysemy. These results supported the claim of the core meaNiNg approach such that the multiple seNses of polysemy share their core meaNiNgs iN their siNgle represeNtatioN, uNlike the wide agreemeNt that the multiple seNses of homoNym are separately represeNted.
