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.The affirmation that there is no single absolute threshold is called signal detection theory. Because our perception responses may vary, to find a person’s absolute threshold researchers conduct multiple tests until they find the amount that is perceived 50% of the time.
