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 granbury dry cleaners

WebFigure 1: The model of sdt. stimulus with a value of x larger than 2 comes from the signal distribution and is given the response Yes. The position of the threshold can also be given relative to the signal distribution (because the noise has zero mean, B is the distance of the threshold relative to the noise distribution), as the mean of WebSignal detection theory (SDT) may be applied to any area of psychology in which two different types of stimuli must be discriminated. We describe several of these areas and the advantages that can be realized through the application of SDT.
