It involves decision-making processes as well as sensory processes.Overview of SDT. SDT’s power as an analytic tool comes from separating a perceiver’s behavior into two underlying components, sensitivity and bias (see Précis of Signal Detection Theory in Supplemental Material available online).

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.

Also commonly referred to as SDT for short, signal detection theory is a psychological concept that is applicable across a wide range of topics.
