WebDec 4, 2024 · December 4, 2024. (a) Introduction to signal detection theory. A simple example of using SDT in experimental psychology is when testing the ability of a subject to detect a short tone pip (beep) in a background of white noise (‘ssss…’; [1]). Over repeated trials subjects are required to decide whether there was a tone present or not. WebThe basic idea behind signal detection theory is that neurons are constantly sending information to the brain, even when no stimuli are present. This is called neural noise. The level of neural noise fluctuates constantly. When a faint stimulus, or signal, occurs, it creates a neural response. WebThe Utility of Signal Detection Theory.
