Definition that contains psychophysics
- weber German physiologist who studied sensory responses to stimuli and is considered the father of psychophysics (1795-1878)
- stevens' power law (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to a power of the stimulus intensity
- fechner's law (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to the logarithm of the stimulus intensity; based on early work by E. H. Weber
- power law (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to a power of the stimulus intensity
- weber's law (psychophysics) the concept that a just-noticeable difference in a stimulus is proportional to the magnitude of the original stimulus
- gustav theodor fechner German physicist who founded psychophysics; derived Fechner's law on the basis of early work by E. H. Weber (1801-1887)

- jnd (psychophysics) the difference between two stimuli that (under properly controlled experimental conditions) is detected as often as it is undetected
- stevens' law (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to a power of the stimulus intensity
