Here, I trace both the origins of signal detection theory and the profound influence it has had on psychology and related fields. My analysis of its origins concentrates on three key developments. The first development was by Gustav Fechner (1860/1966), who conceived of signal detection theory for the two-alternative forced-choice (2AFC) task.
