The Measurement of Sensation

Donald Laming

Abstract

‘Sensation’ is the subjective experience of a physical stimulus. This book traces the sources of two ideas how to measure sensation — Fechner's Law and Stevens' Power Law — and examines the evidence and arguments in their support. Fechner's law is based on discriminations between separate stimulus magnitudes (Weber's Law), together with the additional premise that just noticeable differences are subjectively equal. But such discriminations can be modelled, with equal precision, using Gaussian noise of power density proportional to the stimulus magnitude. Moreover, Gaussian noise accommodates a ... More

Keywords: absolute identification, category judgment, Fechner's Law, magnitude estimation, neural function, sensory discrimination, sensory judgment, Stevens' Power Law
