Weber's law and the Fullerton-Cattell substitute law are special cases of Woodworth's generalized psychophysical law. This assumes that psychophysics measures errors of observation and that in observing larger magnitudes the errors summate according to the laws of chance. But since Woodworth's formula fails to hold, for example, for data on the judgment of lengths of lines compiled by Robinson and Robinson, Guliford proposes a recasting of the psychophysical laws in the form of a general power function:[Equation omitted] in which K and n are experimental constants. In Weber's law n equals 1; in Cattell's law,. 5.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
