化繁为简:视觉集合感知的神经机制
Simplify complexity:The neural mechanisms underlying ensemble perception
摘要
Abstract
Ensemble perception,the process by which the visual system extracts summary statistical information(for example,mean and variance)from groups of similar objects at a glance,is critical to human adaptive functioning.The precise neural mechanisms underlying ensemble perception remain elusive.The present work reviews the temporal dynamics of ensemble perception,evaluates the leading theoretical models with key empirical findings,and further distinguishes the neural substrates between ensemble and single-item processing.Based on existing evidence,the review proposes a"Coarse-Fine-Refine"model,which suggests that during ensemble perception,neural processing proceeds from domain-general,coarse representations mediated by the magnocellular pathway to more detailed,domain-specific representations by parvocellular routes within feature-selective brain regions.Finally,recurrent feedback loops enable iterative calibration of the summary estimate.The review also outlines promising future research directions,including(1)locating the precise neural circuits and cortical areas of ensemble processing,(2)delineating the contributions of feedforward versus feedback signaling,(3)clarifying the domain-general and domain-specific coding in ensemble perception,(4)examining the role of experience and neural development in shaping ensemble perception.关键词
