Outline of Final Research Achievements

High skills can be acquired in long-term training. Among the skills are many implicit knowledge. Past study on work learning focused on working time. However, just only working time is difficult to assess for implicit knowledge acquisition.
In this study, acquisition of implicit knowledge in the process of work learning is evaluated using functional Near Infrared Spectroscopy (NIRS). As a result, we are able to evaluate the state of implicit knowledge acquisition from the state of the worker's brain activity.

Academic Significance and Societal Importance of the Research Achievements

従来研究では、評価すること困難であった暗黙的な知識の獲得に着目し、それを脳の活性状態から評価することを試みた研究である。
この研究成果の応用のひとつに産業界での活用が考えられる。これまでは、作業時間の短縮が作業者の習熟程度を評価する指標であった。しかし、作業時間のみでは、作業のカンコツに相当する暗黙的な知識の獲得程度までは評価することできない。そこに、本研究の成果を応用することで、作業者のカンコツなどの暗黙的な知識の獲得過程を評価し、作業者の熟練度を評価できる可能性がある。
