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 random activity of the detection machine and of the nervous system of the operator). In the field of electronics, signal recovery is the separation of such patterns from a disguising ba… Webβ G β L log(β L) b ʹ k ʹ B ʹ ...

WebSignal 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 of the observer. ... β has a value of 1 when there is no response bias. 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.
