Aug 25, 2023 · Learn how signal detection theory (SDT) explains how humans make decisions based on sensory input. SDT involves assessing the strength of a signal, the confidence in making a decision, and the four possible outcomes of a detection task.
Detection theory is a means to measure the ability to differentiate between information-bearing patterns and random patterns that distract from the information. It has applications in many fields such as psychology, memory, radar, and compressed sensing. Learn the concepts, statistics, and mathematics of detection theory.
Learn how to analyze decision making in the presence of uncertainty using signal detection theory. This web page explains the concepts of information acquisition, criterion, internal response, external noise, and discriminability index with examples and graphs.
Signal Detection Theory is a theory that specifies optimal processes for detecting signals amidst random interference, providing measures of sensitivity and decision criteria. It has applications in various cognitive and practical tasks, such as clinical psychology, information retrieval, and weather forecasting.
Signal detection theory is a statistical decision process that distinguishes between objective sensitivity and subjective response criteria in uncertain situations. It is an important aspect of modern psychophysics research, aiming to separate an individual’s sensitivity to stimuli from their motivations and biases.
