In perceptual, cognitive, and diagnostic tasks, accuracy depends on both limited sensitivity and the application of a decision process. Signal detection theory (sdt) represented a great leap forward in the thinking about sensory phenomena and how to measure them. The reviewer states that a knowledge of signal detection theory is important for its relevance to operant research, as well as for its central position in sensory psychology. Web signal detection theory (sdt) provides a framework for systematically characterizing decision making in the presence of uncertainty, taking into account that the outcome of a decision making process is attributable to both objective information and subjective bias. As radars become more sensitive (capable of detecting weaker and weaker signals), they are increasingly able to correctly detect when signals are present;
Web signal detection theory (green & swets 1966 signal detection theory and psychophysics; Web signal detection theory (sdt) was originally developed to describe the performance of radars, which must detect signals against a background of noise. It is also assumed that each datum is characterized by a particular value on an evidence scale and that the level of the evidence variable is diagnostic Bayesian and signal detection models.
In this chapter the author presents signal detection theory as a framework in which to analyze discrimination and classification data. Web signal detection theory predicts that changes in the payoff matrix—that is, the balance between effort and reward—will be reflected in changes in criterion. It is based on the idea that individuals may pick up on meaningful information, known as “signals,” from noisy and ambiguous stimuli.
