With advancing age, processing resources are shifted away from negative emotional stimuli and toward positive ones. Here, we explored this 'positivity effect' using event-related potentials (ERPs). Participants identified the presence or absence of a visual probe that appeared over photographs of emotional faces. The ERPs elicited by the onsets of angry, sad, happy and neutral faces were recorded. We examined the frontocentral emotional positivity (FcEP), which is defined as a positive deflection in the waveforms elicited by emotional expressions relative to neutral faces early on in the time course of the ERP. The FcEP is thought to reflect enhanced early processing of emotional expressions. The results show that within the first 130 ms young adults show an FcEP to negative emotional expressions, whereas older adults show an FcEP to positive emotional expressions. These findings provide additional evidence that the age-related positivity effect in emotion processing can be traced to automatic processes that are evident very early in the processing of emotional facial expressions.
随着年龄的增长，加工资源从负面情绪刺激转向正面情绪刺激。在此，我们使用事件相关电位（ERP）来探究这种“积极效应”。参与者识别出出现在情绪化面部照片上的视觉探测刺激的有无。记录愤怒、悲伤、快乐和中性面部出现时引发的ERP。我们研究了额中央情绪积极性（FcEP），它被定义为在ERP时间进程早期，相对于中性面部，由情绪表达引发的波形中的正向偏转。FcEP被认为反映了对情绪表达的早期加工增强。结果表明，在最初的130毫秒内，年轻人对负面情绪表达表现出FcEP，而老年人对正面情绪表达表现出FcEP。这些发现提供了额外的证据，表明情绪加工中与年龄相关的积极效应可追溯到在情绪化面部表情加工的早期阶段就很明显的自动加工过程。
