2.	On the role of general cognitive functions during online sentence processing

Research summary
Investigation of the mechanism of online human sentence processing with EEG data Language, which we speak or comprehend effortlessly, is a complex symbolic system that consists of multiple types of information such as phonetic, morphological, syntactic, and semantic one. In spite of such complexity, we usually can understand what a speaker said with little effort. It is assumed that such a high-level but unconscious processing is achieved because human brain is designed to process linguistic information quite quickly and effectively. The aim of my research is to clarify the mechanism of the mental system that enables us to conduct such a quick and effective cognitive process. I am also interested in the interaction between language comprehension system and domain-general cognitive functions such as the inhibition function, working memory, and so on. I employ electroencephalogram (EEG) data such as event-related potentials (ERPs) and oscillatory activities as an index in examining whether a hypothesis is valid or not.
