The theory described in this paper is concerned with the perceptual and cognitive processes underlying psychophysical laws. The theory is a generalization of a model used to predict a subject's conception of the number continuum. It is assumed that all physical attributes (including numbers) undergo a perceptual transformation in terms of the operation of mathematical base systems. Different stimulus attributes are transformed by different bases, leading to transformed intensity values which are “preferred states.” Several new psychophysical equations are developed and compared with the laws of Fechner and Stevens.
