Merkel's law

Show Summary Details

Quick Reference

In psychophysics, the proposition that equal differences in the magnitude of a sensation correspond to equal differences in the intensity of the stimulus causing it. It was not well corroborated by subsequent experimental tests. The term Merkel's law is also an arguably preferable name for Hick's law, because it was first formulated by Merkel. See also psychophysical function. Compare Fechner's law, power law. [Named after the German psychologist Julius Merkel (1834–1900) who formulated it in 1888]
