WEBAug 25, 2023 · Signal Detection Theory Definition. Signal Detection Theory is a psychophysical model that explains how humans make decisions based on sensory information. It is based on the idea that individuals may pick up on meaningful information, known as “signals,” from noisy and ambiguous stimuli.

WEBMar 28, 2018 · 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 … definition

WEBDefinition. Decision making is often associated with uncertainty. 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 of the observer.
