A "matching-response" model of psychophysical judgment is proposed, in terms of which power-law relationships would be expected between perceived intensity and stimulus strength, even though receptors had logarithmic response characteristics. On this model, observed differences in exponent for various modalities would reflect differences in coupling coefficients, rather than in transducer mechanisms.

The fundamental premise of this paper is that subjects code information in such a way that a variety of psychophysical functions can be obtained with the same stimulus attributes. Four terms must beExpand
Psychophysical study of Numbers
SummaryThis paper describes an extension of Preferred State Theory (Baird, 1975) to deal with matching functions produced by such techniques as magnitude and category estimation. It is assumed byExpand

An interpretation of cross-modality matching based on stimulus discriminability rather than sensation magnitude is proposed, of which Fechner's law is a special case. Expand
Linearity as the basic law of psychophysics: Evidence from studies of the neural mechanisms of roughness magnitude estimation
The search for general laws governing our perceptual representation of the external world goes back at least to Fechner and is no less important now than it was then. Fechner used humanExpand
Review: Neural Coding and the Basic Law of Psychophysics
A series of studies aimed at the neural mechanisms of a very complex form of subjective experience, the experience of roughness produced by a textured surface, support the idea that the basic law of psychophysics is linearity between subjective experience and the neural activity on which it is based.

Three dimensions of Fechner’s logarithmic formula are discussed: (1) its methodological character if taken as a measurement formula or as a law of inner psychophysics; (2) the different ways in whichExpand
A framework for Bayesian optimality of psychophysical laws
Abstract The Weber–Fechner law states that perceived intensity is proportional to physical stimuli on a logarithmic scale. In this work, we formulate a Bayesian framework for the scaling ofExpand
Minimal Neural Recruitment from Stevens Coding and Fechner Decoding in the Brain
The psychophysical perceptual process can be taken to occur in two steps. The first one, from sensation to the generation of the neural correlate by population coding is assumed to obey Stevens'Expand
Psychological relations and psychophysical scales: On the status of “direct” psychophysical measurement ☆
Abstract Arguments, originally developed some fifteen years ago, concerning the sort of “direct” psychophysical measurement advocated by S. S. Stevens are reproduced here in order to facilitateExpand

Both sets of data can be fit over the lower range of flash intensities by models based on a saturating response function; both sets deviate from these models at highflash intensities in ways consistent with a nonsaturating responsefunction. Expand
