| Research Abstract |
During comprehending sentence, even if required linguistic information is lacked in a sentence, we can understand the sentence. Previous studies have already pointed out that we have cognitive function to predict or supply the lacked information, however unfortunately, its neural mechanism was still unknown. Therefore, the current study aimed to reveal how our brain predict or supply linguistic information by measuring cortical activation. The result showed increased activation in language-related regions such as so-called Broca's area and so on. This suggests that our brain rapidly starts syntactic and lexico-semantic processes in terms of already constructed sentence construction.
