Signal detection theory. This theory argues that the number of alerts decreases during a continuous performance task. In other words, if your sustained attention is worn thin, the stimulus would have to be more salient for you to detect it. Thus, you might find that when you pay attention for a long period of time, your correct answers decrease.signal detection theory a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise).
