WebMar 28, 2024 · Signal detection theory (SDT) was originally developed to describe the performance of radars, which must detect signals against a background of noise. As radars become more sensitive (capable of detecting weaker and weaker signals), they are increasingly able to correctly detect when signals are present; these events are called hits …
WebSignal detection theory (SDT) is widely accepted by psychologists; the Social Sciences Citation Indexcites over 2,000 references to an influential book by Green and Swets (1966) that describes SDT and its application to psychology. Even so, fewer than half of the studies to which SDT is applicable actually make use of the theory (Stanislaw WebSignal Detection. D.
