Signal Detection Theory. Attempts to predict how and when someone will detect the presence of a given stimulus amidst other sensory stimuli in the background. Study with Quizlet and memorize flashcards containing terms like Weber's Law, Absolute Threshold, Difference Threshold (JND) and more.Signal detection theory. This theory argues that the number of alerts decreases during a continuous performance task. In other words, if your sustained attention is worn thin, the stimulus would have to be more salient for you to detect it. Thus, you might find that when you pay attention for a long period of time, your correct answers decrease.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.Psychology. Signal detection theory (SDT) is used when psychologists want to measure the way we make decisions under conditions of uncertainty, such as how we would perceive distances in foggy conditions or during eyewitness identification.Controllers need to be able to detect planes among many signals (blips) that appear on the radar screen and follow those planes as they move through the sky. In fact, the original work of the researcher who developed signal detection theory was focused on improving the sensitivity of air traffic controllers to plane blips (Swets, 1964).*Signal Detection Theory - a theory predicting how and when we detect the presence of a faint stimulus ("signal") amid background stimulation ("noise").
