The goal of this study was to establish whether the deterioration of the useful visual field due to sleep deprivation and age in a screen monitoring activity could be explained by a decrease in perceptual sensitivity and/or a modification of the participant's decision criterion (two indices derived from signal detection theory). In the first experiment, a comparison of three age groups (young, middle-aged, elderly) showed that perceptual sensitivity decreased with age and that the decision criterion became more conservative. In the second experiment, measurement of the useful visual field was carried out on participants who had been deprived of sleep the previous night or had a complete night of sleep. Perceptual sensitivity significantly decreased with sleep debt, and sleep deprivation provoked an increase in the participants' decision criterion. Moreover, the comparison of two age groups (young, middle-aged) indicated that sensitivity decreased with age. The value of using these two indices to explain the deterioration of useful visual field is discussed.
本研究的目的是确定在屏幕监测活动中，由于睡眠剥夺和年龄导致的有用视野恶化，是否可以通过感知敏感性的降低和/或参与者决策标准的改变（信号检测理论得出的两个指标）来解释。在第一个实验中，对三个年龄组（青年、中年、老年）的比较表明，感知敏感性随年龄增长而降低，且决策标准变得更加保守。在第二个实验中，对前一晚被剥夺睡眠或有完整睡眠的参与者进行了有用视野的测量。感知敏感性随睡眠不足显著降低，睡眠剥夺导致参与者的决策标准增加。此外，两个年龄组（青年、中年）的比较表明，敏感性随年龄降低。还讨论了使用这两个指标来解释有用视野恶化的价值。
