在传统的信息处理层次模型中，视觉表示进入概念系统，但概念类别不会对视觉处理产生影响。我们通过四个实验提供证据，证明概念信息实际上可以渗透早期视觉处理，而不仅仅是偏置感知系统的输出。参与者对视觉上等距的字母刺激对进行物理身份判断，这些字母刺激要么属于同一概念类别（Bb），要么属于不同类别（Bp）。在不同字母的情况下，当刺激来自相同的概念类别时，反应时间会更长，但只有当字母按顺序呈现时。同时试验和序贯试验之间效应大小的差异排除了决策级解释。另一项使用动物轮廓的实验复制了字母的主要影响。因此，明确视觉任务的表现受到概念类别的影响。这种效应取决于处理时间、紧邻的先前经验和刺激典型性，这表明它是由类别知识对感知的直接影响产生的，而不是由感知后决策偏差产生的。
In traditional hierarchical models of information processing, visual representations feed into conceptual systems, but conceptual categories do not exert an influence on visual processing. We provide evidence, across four experiments, that conceptual information can in fact penetrate early visual processing, rather than merely biasing the output of perceptual systems. Participants performed physical-identity judgments on visually equidistant pairs of letter stimuli that were either in the same conceptual category (Bb) or in different categories (Bp). In the case of nonidentical letters, response times were longer when the stimuli were from the same conceptual category, but only when the letters were presented sequentially. The differences in effect size between simultaneous and sequential trials rules out a decision-level account. An additional experiment using animal silhouettes replicated the major effects found with letters. Thus, performance on an explicitly visual task was influenced by conceptual categories. This effect depended on processing time, immediately preceding experience, and stimulus typicality, which suggests that it was produced by the direct influence of category knowledge on perception, rather than by a postperceptual decision bias.
