Detection efficiency of human observers deteriorates rapidly in monotonous monitoring tasks; this effect (the vigilance decrement) has been associated with increased theta band activity in the electroencephalogram. Suppression of theta activity by operant methods enhances monitoring efficiency, whereas theta augmentation further degrades task performance. These results demonstrate a lawful relationship between operantly regulated cortical activity and behavior in man.
在单调的监测任务中，人类观察者的检测效率会迅速下降；这种效应（警觉性下降）与脑电图中θ波段活动的增加有关。通过操作性方法抑制θ活动可提高监测效率，而增强θ活动则会进一步降低任务表现。这些结果证明了人类中操作性调节的皮层活动与行为之间的一种规律性关系。
