An ERP study of the ungrammaticality P600 effect elicitedby nominative NP in NAGARA clauseTakeru ISHIDA † , Takahiro FUKUMORI †† , Mai KIRIKOSHI †††The purpose of this research is to (1) measure event -related potential (ERP) obtained when a sentence
including a non-contradictory reading Nagara clause with a non-grammatical nominative noun phrase (NP)is used as a stimulus and (2) investigate the impli cations of the measured ERP on the distribution restrictionof the nominative NP in the Nagara clause. Since the P600 component, which is said to cause a syntactic
deviation, appeared in the results of the experimentations, the analysis that the distributi on restriction of
nominative NP in a non-contradictory Nagara clause is a syntactic restriction is supported. However, theP600 component appeared only in the group in which the corresponding grammatical Nagara clause sentences were shown as stimulus sente nces and not in the group in which the corresponding grammaticalstimulus sentence was not presented. Regarding the amount of potential, only the corresponding stimulus
sentences could obtain a significant difference. From these results, it was confirmed t hat cases presenting
grammatical pairs of stimulus sentences were more likely to grasp syntactic deviations of non -grammaticalstimulus sentences, and that the P600 effect could be obtained positively.
