| 摘 要： | 目的用事件相关脑电位（ERPs）来研究语义启动下面部表情、手机表情符号和对应情绪字的理解通达机制及其差异。方法被试为19名（9男10女）右利手健康在校大学生。采用Oddball实验模式，要求被试对出现的面部表情、手机表情符号和对应情绪字进行按键正确匹配。记录32导脑电。结果1．被试对三种符号的反应时均为750毫秒左右，无显著统计学意义；2．ERP波形显示面孔的P2波幅最小，对应手机符号最大；3．三者正慢波（PSW）并行并对，字匹配的正慢波波幅最小，面孔最大；结论三种模式识别都包括三个阶段，即前加工阶段、P2阶段和评价检测阶段。PSW反映了模式识别后进行进一步加工的客观指标，是一种复合波，同时也反映了工作记忆中的提取和储存两个阶段的复杂整合。
