Using Signal Detection Theory to Better Understand Cognitive Fatigue. When we are fatigued, we feel that our performance is worse than when we are fresh. Yet, for over 100 years, researchers have been unable to identify an objective, behavioral measure that covaries with the subjective experience of fatigue.

The Signal Detection Theory provides us with a framework to understand the Decision-making process in situations involving uncertainty. Detection of stimuli can depend upon the strength of the subject's senses, and the criterion on the signal's strength decided by the subject for detection. a trail in which a signal is absent. response bias. signal detection theory allows us to explore response bias, which is the tendency of subjects to systematically respond to a stimulus in a particular way due to non sensory factors. note: a significant portion of misses or false alarms gives an indication of response bias in the subject.
