인간과오의 심리생리적 징후와 작업수행도

Psychophysiological Symptoms of Human Errors and Work Performance

In order to catch the relationship between psychophysiological symptoms and human work performance, the ERP technique was adopted as a measure, and two different tasks - a counting task and an Odd-Ball task were conducted. According to the results, the P300 amplitude during the counting task was not so high as that during the Odd Ball task, and correct response corresponded with stable ERP with high P300 amplitude whereas wrong response with unstable, fluctuating ERP with low P300 amplitude, Therefore it was concluded that it would be possible to grasp the symptoms of human errors with the help of psycho-physiological technique.
