The Utility of Signal Detection Theory. Signal detection theory (SDT) is a technique that can be used to evaluate sensitivity in decision-making. Initially developed by radar researchers in the early 1950s ( Peterson et al., 1954 ), the value of SDT was quickly recognized by cognitive scientists and adapted for application in human decision ...

Jan 14, 2021 · Previous work suggests that the metrics of signal detection theory (SDT)—response bias (criterion) and perceptual certainty ( d ’)—may change as a function of fatigue, but no work has yet been done to examine whether these metrics covary with fatigue. Here, we investigated cognitive fatigue using SDT. Updated on 04/19/2018. a body of concepts and techniques from communication theory, electrical engineering, and decision theory that were applied during World War II to the detection of radar signals in noise. These concepts were applied to auditory and visual psychophysics in the late 1950s and are now widely used in many areas of psychology. Here, I trace the origins of signal detection theory, beginning with Fechner's (1860/1966) Elements of Psychophysics. Over and above the Gaussian-based mathematical framework conceived by Fechner in 1860, nearly a century would pass before psychophysicists finally realized in 1953 that the distribution of sensations generated by neural noise ...

The "absolute threshold of sensation" refers to the minimum intensity of a stimulus that a person can detect half the time. This threshold is not fixed, but varies from person to person and can be influenced by psychological factors, such as expectations, motivation, and alertness. The absolute threshold is different from the "difference ...
