Abstract

A paradoxical feature of Weber's law is considered. The law presumably states a principle of psychophysical relativity, yet a pre-relativistic physical measurement model has been traditionally employed. Classical physics, Einsteinian relativity, and a newer interpretation of the relativity concept are discussed. Their relation to psychophysics is examined. The domain wherein Weber's law breaks down is noted as suggestively similar to that in which physicists report relativistic effects. A tentative hypothesis is offered to stimulate further thought about a more meaningful integration of psychophysics with modern physical science.
