パフォーマンステストによる知的生産性改善評価時のNIRS を用いた脳活動計測

摘要

著者らはプロダクティビティを客観的かつ定量的に評価するための指標としてCPTOP2開発を行ってきた。CPTOP2は4種類の問題からなるタスクセットであり、各タスクが異なる知的能力に対応することを意図して開発されたが、タスク遂行時に実際にその知的能力が用いられていることを客観的に判断する材料が少ないという問題があった。%CPT0P2 is an intellectual performance test set which consists of four kinds of cognitive task tests, and has been developed in order to measure the improvement of intellectual productivity of office workers by improving office environment. In this study, the brain activities of six office workers when performing CPTOP2 under two illumination conditions were measured by near infrared spectroscopy (NIRS). As the result, it was found that the blood stream of intended brain anatomies increased corresponding to the task tests, and confirmed that CPT0P2 were well-designed to activate intended brain anatomy. In addition, the relationship between improvement of office environment and intellectual productivity was discussed based on the experimental result.
