Signal detection theory ap psychology.

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 (SDT) is used when psychologists want to measure the way we make decisions under conditions of uncertainty, such as how we would perceive distances in foggy conditions or during eyewitness identification.The absolute threshold is an important tool for researchers studying the capabilities and limitations of human sensation and perception. It is defined as the lowest stimulus level that an organism can detect at least half the time. These limits can vary depending on factors such as motivation, expectation, and attention.
