Classical linguistic theory assumes that formal aspects, like sound, are not internally related to the meaning of words. However, recent research suggests language might code affective meaning such as threat and alert sublexically. Positing affective phonological iconicity as a systematic organization principle of the German lexicon, we calculated sublexical affective values for sub-syllabic phonological word segments from a large-scale affective lexical German database by averaging valence and arousal ratings of all words any phonological segment appears in. We tested word stimuli with either consistent or inconsistent mappings between lexical affective meaning and sublexical affective values (negative-valence/high-arousal vs. neutral-valence/low-arousal) in an EEG visual-lexical-decision task. A mismatch between sublexical and lexical affective values elicited an increased N400 response. These results reveal that systematic affective phonological iconicity - extracted from the lexicon - impacts the extraction of lexical word meaning during reading.
经典语言理论假设形式方面，如声音，与单词的意义没有内在联系。然而，最近的研究表明，语言可能会在亚音节水平上编码情感意义，如威胁和警报。我们假设情感语音象似性是德语词汇系统组织原则，通过平均所有出现特定语音段的单词的效价和唤醒评分，我们从大型情感德语词汇数据库中为亚音节语音单词段计算出亚音节情感值。我们在 EEG 视觉词汇决策任务中测试了具有词汇情感意义和亚音节情感值之间一致或不一致映射的单词刺激（负价/高唤醒与中性价/低唤醒）。亚音节和词汇情感值之间的不匹配会引起 N400 反应的增加。这些结果表明，从词汇中提取的系统情感语音象似性会影响阅读过程中词汇词义的提取。
