Psychophysical measurement

Psychophysics also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement, [3] ideal observer analysis, and signal detection theory. [4] Psychophysics has widespread and important practical applications.

WebOne of the earliest characteristics of human sensory function to be measured was the absolute threshold. The absolute or detection threshold was seen as an energy level below which no sensation would be produced by a stimulus and above which a sensation would reach consciousness. The concept of threshold was central to Fechner’s psychophysics.
