本研究的目的是建立是否可以解释的有用视野的恶化，由于睡眠剥夺和年龄在屏幕监测活动的感知灵敏度和/或修改的参与者的决策标准（两个指数来自信号检测理论）的下降。在第一个实验中，三个年龄组（青年，中年，老年人）的比较表明，知觉灵敏度随着年龄的增长而下降，决策标准变得更加保守。在第二个实验中，对前一天晚上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。知觉灵敏度随着睡眠不足而显著下降，睡眠剥夺引起参与者决策标准的增加。此外，两个年龄组（青年，中年）的比较表明，敏感性随着年龄的增长而下降。讨论了用这两个指标解释有用视野退化的价值。
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.
