Abstract: Groupitizing, as one of the important strategies for numerosity perception, features both subitizing and counting, influencing individual arithmetic abilities. Although previous research has shown a close relationship between perceptual grouping and numerosity perception, it has mostly examined the phenomenon of numerosity perception grouping from the unidirectional perspectives of either space or time. It has particularly neglected the roles played by internal and external cues of perceptual grouping, as well as the spatial, temporal, and motion dimensions that share the same magnitude system in the strategy of numerosity perception grouping. The psychological and physiological mechanisms underlying these effects remain unclear to date. Building on prior research, this study aims to investigate the cognitive neural mechanisms influencing numerosity perception grouping strategies across different magnitude system dimensions by integrating behavioral measurements, ERP, and fMRI techniques. It seeks to deeply elucidate the role of perceptual grouping in the formation of numerosity perception grouping, providing a more comprehensive understanding of the nature and psychological-physiological mechanisms of numerosity perception grouping strategies, ultimately offering a basis for achieving efficient mathematical learning.
