摘要: 本研究采用事件相关电位(ERP)方法探讨青少年情绪性加工的脑电反应发展性特征。测量并比较了48名分别处于三个年龄阶段(12~13岁, 16~17岁, 19~21岁)的个体在观看三类情绪图片(积极、中性、消极)时的事件相关电位。结果显示, 三个年龄阶段的个体对情绪性图片刺激进行加工, 通过主观报告能够明确区分情绪意义, 其评价顺序与成人一致, 同时, ERP的300~900ms时段从顶枕区到整个脑区呈现和成人研究一致的波形特征, 即情绪性刺激引起ERP的晚期成分相对于非情绪性刺激引起更正的波幅; 三个年龄阶段的个体在脑电活动的时程上表现出从后侧脑区向前侧扩散的趋势, 低龄组个体枕区的ERP活动程度高于高龄组个体, 而高年龄组个体在额区、颞区、中央区位置的ERP活动比低龄组个体更强。结合主观报告, 上述ERP结果展示了青少年情绪性加工脑电反应的发展性特征
