采用事件相关电位（ERPs）技术，考察了句子语境、语义记忆组织和知觉可预测性对图片加工的影响。参与者阅读成对的高度或弱约束的句子，这些句子以（a）预期的项目，（B）预期语义类别中的意外项目，或（c）意外类别中的意外项目结束。图片是不熟悉的实验1，但在实验2中预先曝光。图片的事件相关电位反映了背景匹配和记忆组织，同样的背景下单词的事件相关电位也反映了背景匹配和记忆组织。D. Federmeier & M. Kutas，1999年）。然而，不同的反应模式，观察到的图片比文字。其中一些产生知觉的可预测性差异，而其他人似乎反映了真正的模态为基础的语义特征激活的差异。虽然单词和图片可能共享语义记忆，但作者的研究结果表明，语义加工不是无模式的。
Using event-related potentials (ERPs), the authors investigated the influences of sentence context, semantic memory organization, and perceptual predictability on picture processing. Participants read pairs of highly or weakly constraining sentences that ended with (a) the expected item, (b) an unexpected item from the expected semantic category, or (c) an unexpected item from an unexpected category. Pictures were unfamiliar in Experiment 1 but preexposed in Experiment 2. ERPs to pictures reflected bath contextual fit and memory organization, as do ERPs to words in the same contexts (K. D. Federmeier & M. Kutas, 1999). However, different response patterns were observed to pictures than to words. Some of these arose from perceptual predictability differences, whereas others seem to reflect true modality-based differences in semantic feature activation. Although words and pictures may share semantic memory, the authors' results show that semantic processing is not amodal.
