Experimental data of “The Influence of Internal and External Cues and Stimulus Onset Asynchrony on Temporal Numerosity Perception: Evidence from fMRI”

Grouping is a processing strategy in which individuals organize stimuli into subsets based on perceptual grouping cues to quickly and effectively estimate quantities. The current research on quantity aware grouping strategies mainly focuses on spatial conditions, but the processing mechanism under temporal conditions is still unclear. This study used a quantity estimation task combined with fMRI technology to explore the neural mechanisms of grouping strategies under temporal conditions in a sequential presentation manner. The dataset includes behavioral data, FMRI data, and experimental programs
