Signal Detection Theory - an overview ScienceDirect Topics

Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and … See more 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 See more P(H1 y) > P(H2 y) / MAP testing In the case of making a decision between two hypotheses, H1, absent, and H2, present, in the event of a particular observation, y, a classical approach is to choose H1 when p(H1 y) > p(H2 y) and H2 in the reverse case. … See more Signal Detection Theory has wide application, both in humans and animals.
