| Outline of Final Research Achievements |
In this study, we investigated whether it is possible to estimate the margin of the brain from the EEG response to this radio news. There were the three conditions: when listening radio news and watching silent videos participants were paying attention to radio news (condition 1), when listening radio news and watching silent videos participants were paying attention to silent video (condition 2), and when listening only to radio news participants were paying attention to radio news (condition 3).
The brain responses to the radio news were extracted. As a result, we were able to obtain a significant difference in response intensity between the conditions. This suggests that it may be possible to extract brain information related to the margin of the brain.

| Academic Significance and Societal Importance of the Research Achievements |
作業のミスを発生させる原因は，精神的，身体的な疲労の結果，脳に「余裕」がなくなり，作業に対して集中が出来なくなったからであるともいえる．疲労による脳への影響は様々であると考えられるが，ミスに直接的につながる「脳の余裕度」をリアルタイムに計測することが出来れば，作業ミスなどを防ぐことが出来る可能性がある．今後は，本研究で抽出した脳の余裕度に関連する脳活動を利用してミスなどのトラブルの発生を予測することで，トラブルを未然に防ぐことができる可能性がある．
