Perceptual learning in vision has been found to be highly specific for simple stimulus attributes, implying highly specific modifications in the nervous system. The type of specificity found (location, orientation, eye) implied plasticity at very early stages of visual processing, where processing modules were believed to be hard-wired and task independent. Recent studies show, however, that learning is task dependent. Studies examining the time course of learning indicate that at least two different learning processes are involved in perceptual learning, reflecting different levels of processing. Perceptual learning appears to be governed by associative rules and to be constrained by system architecture.
视觉中的知觉学习已被发现对简单刺激属性具有高度特异性，这意味着神经系统中存在高度特异性的改变。所发现的特异性类型（位置、方向、眼睛）暗示了视觉处理非常早期阶段的可塑性，在这个阶段，处理模块被认为是硬连线的且与任务无关。然而，最近的研究表明，学习是依赖于任务的。对学习时间进程的研究表明，知觉学习至少涉及两个不同的学习过程，反映了不同的处理水平。知觉学习似乎受关联规则支配，并受系统架构的约束。
