Abstract

The article discusses a proposed combinatorial model of perceptual categorization that aims to provide a unifying mathematical foundation for classical psychophysics, which traditionally describes the relationship between physical stimulus intensity and subjective sensation. The model utilizes set partitions and equivalence relations to conceptualize perception as a process of grouping stimuli into indistinguishable categories. It suggests that the expected number of perceptual categories increases with the number of stimuli according to a sigmoidal law, ultimately aligning with established psychophysical laws, such as Stevens' power law and Fechner's logarithmic law. The research is based on a preprint and has not yet undergone peer review. [Extracted from the article]
