| Outline of Final Research Achievements |
This study examined the neural basis of pragmatic inference by EEG experiments. We manipulated context to control the type of inference, namely, deduction and abduction. In the experiment in which discourses were visually presented to Japanese native speakers, we observed negative event-related potentials (ERPs) around the latency of 500 ms for understanding implicit meaning. The amplitude of ERP for the latter was greater than the former. The generators for the ERPs were localized in the frontal and occipital regions of medial part. This suggests that the pragmatic inference was performed simultaneously in multiple regions in the brain.
