Using event-related potential measures, the present study investigated the affective responses to aesthetic experience. To differentiate the objective aesthetic value from subjective aesthetic evaluation, an amended oddball task was used in which pendant pictures were presented as frequent nontarget stimuli, whereas the landscape pictures were presented as a rare target. The pendant pictures were chosen from the largest online store in China and divided into beautiful and less beautiful conditions by the sales ranking. A positive component, P2, was recorded for each condition on the participantsrsquo; frontal, central and parietal scalp areas. Less beautiful pendants elicited greater amplitudes of P2 than the beautiful ones. This indicates that emotion arousal seems to occur at the early stage of processing of aesthetics and can be detected by the P2 component, implying that the event-related potential methodology may be a more sensitive measure of the beauty-related attention bias. From the perspective of artwork design and marketing, our finding also shows that P2 can potentially be used as a reference measure in consumer aesthetic experience.

本研究采用事件相关电位的方法，对审美体验的情感反应进行了研究。为了将客观审美价值与主观审美评价区分开来，采用了一种修正后的任务，其中的垂饰图片呈现为频繁的非目标性刺激，而风景图片则呈现为罕见的目标。这些垂饰图片是从中国最大的网上商店中挑选出来的，按销售排名分为美丽和不太美的情况。在参与者的额部，中部和头顶部的头皮区域记录每个条件的积极部分P2。不漂亮的垂饰比美丽的垂饰更能激发P2的振幅。这表明情绪唤醒似乎发生在美学处理的早期阶段，可以通过P2成分来检测，这意味着事件相关电位方法可能是一个更敏感的测量与美学有关的注意偏向。从艺术品设计和市场营销的角度来看，我们的发现也表明P2可以作为消费者审美体验的参考指标。
