Outline of Final Research Achievements

We developed an experimental paradigm to investigate the relationship between the consistency in electroencephalographic (EEG) responses to repeatedly presented visual noise and developmental disability. We conducted EEG experiments and analyzed the obtained data. We developed a dual-task paradigm to control the attentional state and arousal level. We used questionnaires to measure the traits of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in healthy individuals. We explored the relationship between the degree of EEG consistency and these psychological traits. Although we need more data, we succeed in developing a novel experimental paradigm to assess the relationship between the psychological traits and noise-induced EEG dynamics.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、視覚ノイズ誘起脳波により、ASD、ADHD傾向などの発達障害傾向を評価する新規な実験解析手法の確立を目指した。これまでの我々の実験パラダイムでは注意や覚醒レベルなどの影響要因をコントロールするのが難しかったが、それらのコントロールが可能な実験パラダイムの構築に成功した。発達障害特性の、比較的簡便な脳波計測とデータ解析による理解や評価が可能となり、学術的、社会的にも意義がある。
