This can be applied to all our senses: The minimum intensity of light we can see. The lowest volume of a sound we can hear. The smallest concentration of particles we can smell. 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.
