情感图片处理的事件相关电位（ERP）研究已经证明了嵌入快速视觉流中的情感唤起图片的早期后验负波（EPN）。本研究探讨了选择性处理的情绪图片，同时系统地改变图片呈现率之间的1和16赫兹。先前的结果与呈现率高达5 Hz的复制，情绪相比，中性的图片与更大的EPN。情感和中性内容之间的歧视保持高达12赫兹。为了探讨并行处理的概念，卷积分析：由线性叠加的慢速率ERP产生的EPN解释了70%-93%的方差测量EPN，提供证据的一个令人印象深刻的能力的并行情感歧视在快速串行图片呈现。
Event‐related potential (ERP) studies of affective picture processing have demonstrated an early posterior negativity (EPN) for emotionally arousing pictures that are embedded in a rapid visual stream. The present study examined the selective processing of emotional pictures while systematically varying picture presentation rates between 1 and 16 Hz. Previous results with presentation rates up to 5 Hz were replicated in that emotional compared to neutral pictures were associated with a greater EPN. Discrimination among emotional and neutral contents was maintained up to 12 Hz. To explore the notion of parallel processing, convolution analysis was used: EPNs generated by linear superposition of slow rate ERPs explained 70%–93% of the variance of measured EPNs, giving evidence for an impressive capacity of parallel affective discrimination in rapid serial picture presentation.
