I am studying the brain mechanisms of human language. Using fMRI, I have verified that the Broca's area is the brain region responsible for the construction of hierarchical structures in sentence processing. Similar hierarchical structures exist in mathematics and music, which also activate Broca's area. Language, mathematics, and music are all symbolic sequences in which multiple symbols are linearly connected, and we believe that the essence of hierarchical structure is that symbolic sequences have cohesion among symbols and cohesion of cohesion. We have experimentally shown that there is a hierarchical structure in drawing, which is an important symbolic ability unique to humans. We are conducting a neuroscientific study of what symbols are and why they exist only in humans, while also incorporating an evolutionary perspective.

The research I am currently working on is
- Language impairment in autism as an affective computation deficit in the hierarchy of sentence-final particles
- Biological basis of drawing ability: comparative study of humans, chimpanzees, gorillas, monkeys, and tigers
- Survey of ICT use by the hearing impaired in the COVID-19 epidemic and development of information materials based on successful examples of ICT use
The are.

We are involved in a study investigating the correlation between vowel lengthening and autistic tendencies in everyday conversation in modern Japanese. In conversations with people with autistic spectrum disorder (ASD), misunderstandings and miscommunications may unwillingly occur due to their characteristic ways of communicating and understanding language. They are mainly problems based on pragmatics (the use of language) rather than on the level of meaning (the literal meaning of words). 'Vowel lengthening' is one of the speech features that is heavily influenced by the pragmatic level in its production and interpretation. Using this phenomenon as a starting point, we aim to identify one of the language barriers that people with ASD encounter in social life and to develop a language environment that is more accommodating for people with ASD to live in.
