摘要
视知觉学习(VPL)是指个体通过训练或实践在相关视觉任务中表现出显著且持久改善的一种知觉可塑性现象。VPL在眼病患者视功能康复中起着重要作用, 然而, 对于VPL的潜在神经机制, 特别是学习发生在视觉信息处理的哪个阶段, 尚存争议。事件相关电位(ERP)技术凭借其高时间分辨率的优势, 能够记录视觉信息处理过程中各阶段的大脑活动变化。笔者综述了利用ERP技术开展的VPL研究中所采用的视觉任务及其引发的各ERP成分的变化, 旨在加深我们对VPL神经机制的理解。
Visual perceptual learning(VPL)represents a phenomenon of perceptual plasticity,whereby an individual exhibits substantial and enduring enhancement in a pertinent visual task through training or practice.VPL plays an important role in the rehabilitation of visual function in patients with ocular disease.However,there is controversy surrounding the underlying neural mechanisms of VPL,particularly regarding the stage of visual information processing at which learning occurs.Event-related potential(ERP)technology,with its high temporal resolution,is capable of recording alterations in brain activity at various stages of visual information processing.This paper provides an overview of the visual tasks employed in VPL studies using ERP technology,together with an examination of the changes in each of the ERP components that they trigger.The objective is to deepen our understanding of the neural mechanisms of VPL.
