当受试者在没有进一步指导的情况下阅读连续呈现的单词序列时，记录脑电图事件相关脑电位。我们改变了序列呈现的速度（3 Hz和1 Hz）和单词的情感意义。阅读过程中的早期事件相关皮层反应将愉快和不愉快的单词与中性单词区分开来。情绪的话与增强的大脑反应，主要是左枕颞区200至300毫秒后，介绍。情绪化的词也比中性词更容易被记住。早期皮层放大在10次重复中是稳定的，这为具有学习情感意义的刺激的早期视觉处理的稳健增强提供了证据，并强调了阅读过程中情感内涵的显著性。在早期的处理阶段，情绪相关的皮层活动的增强沿着主要的处理途径是由于唤醒，而不是刺激的效价。这种增强可能是由皮质-杏仁核连接驱动的。
Electroencephalographic event-related brain potentials were recorded as subjects read, without further instruction, consecutively presented sequences of words. We varied the speed at which the sequences were presented (3 Hz and 1 Hz) and the words' emotional significance. Early event-related cortical responses during reading differentiated pleasant and unpleasant words from neutral words. Emotional words were associated with enhanced brain responses arising in predominantly left occipito-temporal areas 200 to 300 ms after presentation. Emotional words were also spontaneously better remembered than neutral words. The early cortical amplification was stable across 10 repetitions, providing evidence for robust enhancement of early visual processing of stimuli with learned emotional significance and underscoring the salience of emotional connotations during reading. During early processing stages, emotion-related enhancement of cortical activity along the dominant processing pathway is due to arousal, rather than valence of the stimuli. This enhancement may be driven by cortico-amygdaloid connections.
