视觉信息加工通路与注意机制的关系研究综述

Visual Information Processing Pathways and Attentional Mechanisms: A Review

摘要: 注意是人类认知系统中的核心功能，其通过选择性地处理信息来优化有限的认知资源。近年来，越来越多的研究关注视觉信息加工通路与注意机制之间的关系。本文系统综述了视觉信息加工通路的神经解剖学基础、生理特性，以及它们在注意定向、注意捕获和注意抑制等过程中的作用。研究表明，不同的视觉通路在注意加工中具有相对分离的功能：大细胞通路(M通路)主要参与快速的注意定向和空间位置加工，而小细胞通路(P通路)则更多地参与精细的特征分析和物体识别。此外，背侧视觉流和腹侧视觉流在注意加工中也表现出通路特异性。本文还探讨了视觉通路与注意时间动力学的关系，以及通路损伤对注意功能的影响。最后，本文指出了当前研究的局限性，并对未来研究方向提出了展望。

Abstract: Attention is a core function of the human cognitive system that optimizes limited cognitive resources through selective information processing. In recent years, increasing research has focused on the relationship between visual information processing pathways and attentional mechanisms. This article systematically reviews the neuroanatomical foundations and physiological characteristics of visual information processing pathways, as well as their roles in attentional orienting, attentional capture, and attentional inhibition. Research indicates that different visual pathways have relatively distinct functions in attentional processing: the magnocellular pathway is primarily involved in rapid attentional orienting and spatial location processing, whereas the parvocellular pathway is more engaged in fine-grained feature analysis and object recognition. Furthermore, the dorsal and ventral visual streams also exhibit pathway-specific characteristics in attentional processing. This review also explores the relationship between visual pathways and the temporal dynamics of attention, as well as the impact of pathway lesions on attentional function. Finally, this article identifies limitations of current research and proposes directions for future investigation.
