行为和电生理反应进行了监测，以80个控制组的情绪积极，消极和中性词随机呈现的词汇决策范式。一半是低频词，一半是高频词。行为的结果表明，频率和情绪，以及互动的显着影响。先前的研究表明，事件相关脑电位（ERP）的N1成分对词汇加工敏感。在本研究中，NI（135-180 ms）通过频率交互显示出显著的情绪。检查N1之前的P1窗口（80-120 ms）以及N1之后的时间窗口，包括早期后负波（200-300 ms）和P300。ERP数据表明，早期识别的情绪基调（300-450毫秒），字导致差异处理。具体来说，高频率的负面词似乎吸引额外的认知资源。结果的整体模式是一致的单词识别的时间线，其中语义分析，包括情感质量的评价，发生在早期，词汇阶段的处理。(c)2008 Elsevier B.

Behavioral and electrophysiological responses were monitored to 80 controlled sets of emotionally positive, negative, and neutral words presented randomly in a lexical decision paradigm. Half of the words were low frequency and half were high frequency. Behavioral results showed significant effects of frequency and emotion as well as an interaction. Prior research has demonstrated sensitivity to lexical processing in the N1 component of the event-related brain potential (ERP). In this study, the NI (135-180 ms) showed a significant emotion by frequency interaction. The P1 window (80-120 ms) preceding the N1 as well as post-N1 time windows, including the Early Posterior Negativity (200-300 ms) and P300 were examined. The ERP data suggest an early identification of the emotional tone of (300-450 ms), words leading to differential processing. Specifically, high frequency negative words seem to attract additional cognitive resources. The overall pattern of results is consistent with a time line of word recognition in which semantic analysis, including the evaluation of emotional quality, occurs at an early, lexical stage of processing.
