Outline of Final Research Achievements

The result of an ERP experiment in this study suggested that the "semantic P600 effects" which has been considered the evidence of the interaction between multiple sources of linguistic information during online sentence processing are elicited by the external effects such as task demands and filler sentences. Furthermore, this study revealed that the brain's oscillatory activities sometimes showed significant change in the same latency as a N400 effect or a P600 effect but other times showed no significant change in response to the syntactic or semantic anomalies which elicited larger N400 or P600 effects. Moreover, the results of an experiment in this study indicated that brain's oscillatory activities can be useful tool for investigating the first-pass processing which ERPs are not good at looking into.
