摘要：The present study was designed to examine a relation between evoked GSR at the cases of signal presentation and signal detection or detection performance in a visual (experiment 1) and an auditory (experiment 2) vigilance task. In experiment 1 two tasks lasting for 30 min without (task A) and with (task B) monitoring the outer response to the signal were carried out on 10 healthy young men. The experi- ment 2 which was performed by another 10 subjects was the same as the experiment 1 except that auditory signals were used. It was found that the GSR did not always occur at the cases of signal detection with monitoring the outer response to the signal in both experiments 1 and 2. It was also found that signal presentation accompanied by GSR during the task B was high as compared with that during the task A in both experiments 1 and 2. Although there was no significant correlation between signal presentation accompanied by GSRduring the task A and detection performance during the task B in both experiments 1 and 2, a statistical correlation between the signal presentation or signal detection accompanied by GSR during the task B and the detection performance during the task B in the experiment 2 was significant. From the results observed in the auditory vigilance task, it seems likely that detection performance is roughly evaluated by signal presentation or signal detection accompanied by GSR.
