12 subjects performed a vigilance task in which signals were presented in two squares of a display according to two variable-time schedules. The subjects reported any detections of the signals by pressing a key. Latencies of the reported responses should be less than 0.3 sec. or 1.2 sec. to be reinforced. Half of the subjects were informed of the signal frequencies while the other half were not. The former subjects showed longer durations of fixation for the squares providing more signals. Such differentiations were larger under the 0.3-sec, condition than the 1.2-sec. condition. The latter group of subjects showed neither of these effects. The results suggested that different degrees of immediacy of responding might engender different patterns of eye movements.
12名受试者执行了一项警觉任务，在该任务中，信号根据两个可变时间安排出现在显示器的两个方块中。受试者通过按键报告任何信号检测情况。报告反应的潜伏期应小于0.3秒或1.2秒才能得到强化。一半的受试者被告知信号频率，而另一半则未被告知。前一组受试者对提供更多信号的方块表现出更长的注视持续时间。在0.3秒的条件下，这种差异比1.2秒的条件下更大。后一组受试者没有表现出这些效应。结果表明，不同程度的即时反应可能会产生不同的眼动模式。
