三个实验考虑了几个任务特征的影响，沿着一天中测试警惕性的时间。第一个实验发现，巴肯任务的检测取决于事件率和信号频率，降低信号频率的不利影响在下午比上午更显着。第二个实验发现，一个简短的，快节奏的连续的歧视任务的典型的敏感性递减发生时，刺激被降级，特别是在傍晚与上午相比，并在晚上采用了一个更危险的标准放置。第三个实验使用了等概率刺激事件的非节奏同步辨别任务。效率并不稳定，而是随着时间的推移而下降，而速度则增加。这些变化往往在下午更明显，感知效率似乎真的比上午低。解释的警惕性和时间或天的影响进行了讨论。
Three experiments consider the effects of several task features along with the time of day when vigilance was tested. The first experiment found that detections on the Bakan task depended on event rate and signal frequency and that the adverse effects of lowering signal frequency were more marked in the afternoon than in the morning. The second experiment found that the typical sensitivity decrement on a brief, rapidly paced successive discrimination task occurred earlier when the stimuli were degraded—especially in the early evening as compared with the morning—and that a riskier criterion placement was adopted in the evening. The third experiment used an unpaced simultaneous discrimination task with equiprobable stimulus events. Efficiency was not stable but declined as time passed, while speed increased. These changes tended to be more apparent in the afternoon, and perceptual efficiency seemed genuinely lower than in the morning. The implications for interpretations of vigilance and time-or-day effects are discussed.
