| 摘 要： | 用信号察觉反应时与信号误报率作指标 ,对监视作业中监视仪表数量与信号间隔时距对监视作业效绩的影响问题进行研究。结果表明 ,监视作业的效绩会随仪表增多和信号间隔时距增大而呈下降趋势。当监视仪表达到 8个时 ,监视作业的效绩会因负荷过重而明显下降。信号出现间隔时距增长时 ,会因警戒水平下降使监视仪表作业的效绩明显降低。

| Abstract: | Supervision is a very important activity in the operation of large automatic man machine system. The present study was designed to investigate the effects of dial number and signal interval on supervisory performance. The independent variables were dial number and signal interval. Dial numbers were 2, 4, 6, and 8 numbers. Signal intervals were 30 90 seconds, 3 7 minuets and 12 18 minutes. Eighteen undergraduates and graduate students (12 male, 6 female) from Hangzhou university participated in the experiment. They were required to press the response key as soon as a signal appeared on the screen. Reaction time and error rate were recorded. The results showed that as the dial numbers or signal intervals increased, supervisory performance decreased. Statistical comparison indicated that there were some significant differences of reaction time between 2 dials and 8 dials in all signal intervals (P<0 05), and a significant difference of error rates between 30 90 second interval and 12 18 minute interval (p<0.05). |
