Signal detection theory a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness.Abstract. In perceptual, cognitive, and diagnostic tasks, accuracy depends on both limited sensitivity and the application of a decision process. By making explicit assumptions about the nature of the cognitive representation, signal detection theory (SDT) measures the contributions of these two components of performance.Signal detection theory explains the way that an observer detects a weak, uncertain, or ambiguous event or signal.

A final chapter contains a general discussion …Signal detection theory (SDT) provides a framework for characterizing decision making in the presence of uncertainty, taking into consideration that the decision depends both on actual objective information and possible subjective biases of the observer.
