Psychophysical laws as reflection of mental space properties
Ihor Lubashevsky

TL;DR
This paper develops a theory linking psychophysical laws to properties of mental space, explaining key psychophysical regularities and proposing a solution to the Fechner-Stevens dilemma based on mental image processing.
Contribution
It introduces a novel mental space framework that accounts for psychophysical phenomena and clarifies the origin of Fechner's law separate from Weber's law.
Findings
Explains regression and range effects in perception.
Accounts for Weber's and Ekman's laws through mental image variability.
Provides a new perspective on the Fechner-Stevens dilemma.
Abstract
The paper is devoted to the relationship between psychophysics and physics of mind. The basic trends in psychophysics development are briefly discussed with special attention focused on Teghtsoonian's hypotheses. These hypotheses pose the concept of the universality of inner psychophysics and enable to speak about psychological space as an individual object with its own properties. Turning to the two-component description of human behavior (I. Lubashevsky, Physics of the Human Mind, Springer, 2017) the notion of mental space is formulated and human perception of external stimuli is treated as the emergence of the corresponding images in the mental space. On one hand, these images are caused by external stimuli and their magnitude bears the information about the intensity of the corresponding stimuli. On the other hand, the individual structure of such images as well as their subsistence…
