摘要
为了探索警戒作业绩效的影响因素,并试图探索颜色警示和声音警示对警戒绩效下降的改善作用。此研究通过计算机程序模拟Mackworth的雷达"时钟测验",以指针(秒针)跳动2格作为信号,来研究警戒作业绩效。实验方法采用随机区组设计,信噪比为平均1/30。结果表明,2小时的连续常规警戒作业,存在显著的警戒下降现象;声音警示、颜色警示或视听结合警示对警戒绩效有显著的影响作用。伴随有声音警示的警戒绩效最好,且优于颜色警示,颜色警示优于无警示提示的警戒作业绩效。为了防止警戒下降,可以通过听觉声音警示、视听结合警示或视觉颜色凸显警示来改善警戒作业绩效。
To explore factors effects of color cue and sound cue, experiments were made to simulate Mackworth＇ clock test monitoring radar task in a computer program. The methods of random block design and an average rate of about one-thirtieth of the signal were adopted in the experiment. The results indicated that the existence of performance degrading was detected in the two-hour normal vigilance task, and the effects of sound cue or color cue or sound and color cue effects on the vigilance performances were found to be remarkable. Thus sound cue or color cue or sound and color cue can be used to enhance vigilance performances.
