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

分组（Grouping）是一种信息加工策略，个体可依据知觉分组线索将刺激物划分为若干子集，从而实现快速且高效的数量估计。当前针对数量感知分组策略的研究主要聚焦于空间维度条件，而时序条件下的加工机制仍未明确。本研究采用数量估计任务结合功能磁共振成像（fMRI）技术，以序列呈现范式探究时序条件下分组策略的神经机制。本数据集包含行为学数据、功能磁共振成像数据以及实验程序。
