Signal detection theory models signals and noise as two probability distributions

Evidence

Green and Swets (1966) developed a robust framework within which to characterize this problem and termed it signal detection theory. In this framework, we can consider the internal response generated by a signal (or the absence of one) to be represented by two probability distributions. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 330
