Outline of Final Research Achievements

The study was intended to find the neural activity specific to the interpersonal interaction by examining the electroencephalogram associated with verbal communication. However, we performed a questionnaire study to analyze the correlations between the sociality of participants evaluated by the Japanese version of interpersonal reactivity index (IRI) and their verbal behaviors and neural activity we observed in the previous experiments because we could not perform a new experiment due to the pandemic. The results showed that the individual differences in language use, which were generally regarded as noise, had regularity according to the subsores of IRI of each individual. The results also suggested that the neural activity associated with verbal communication varied according to their gender and individual social differences.

Academic Significance and Societal Importance of the Research Achievements

コミュニケーション能力に社会的関心が集まる一方で、その実態は不明である。特に教育場面において、コミュニケーション能力への関心が混乱を招いている面もある。コミュニケーション能力の詳細を神経科学的手法によって科学的に明らかにすることで、コミュニケーション能力の正確な理解を深め、コミュニケーション能力養成に貢献することで学生ならびに指導者の不安を解消することができる可能性があると考えている。
