title: Fechner's psychophysical law as a special case of Stevens' three-parameter power law.
abstract: This paper shows that Fechner's law of psychophysics is a special case of Stevens' power law with three parameters. Consequently, at least as good over-all fit to experimental data is always obtained, at the cost of one additional parameter, by using Stevens' power law involving an extra parameter added to the response variable.
