Samuel B. Barnett, and Moran Cerf (2017), “A ticket for your thoughts: Method for predicting content recall and sales using neural similarity of moviegoers,” Journal of Consumer Research, 44(1), 160-181.
Skilled advertisers often cause a diverse set of consumers to feel similarly about their product. We present a method for measuring neural data to assess the degree of similarity between multiple brains experiencing the same advertisements, and we demonstrate that this similarity can predict important marketing outcomes. Since neural data can be sampled continuously throughout an experience and without effort and conscious reporting biases, our method offers a useful complement to measures requiring active evaluations, such as subjective ratings and willingnessto- pay (WTP) scores. As a case study, we use portable electroencephalography (EEG) systems to record the brain activity of 58 moviegoers in a commercial theater and then calculate the relative levels of neural similarity, cross-brain correlation (CBC), throughout 13 movie trailers. Our initial evidence suggests that CBC predicts future free recall of the movie trailers and population-level sales of the corresponding movies. Additionally, since there are potentially other (i.e., non-neural) sources of physiological similarity (e.g., basic arousal), we illustrate how to use other passive measures, such as cardiac, respiratory, and electrodermal activity levels, to reject alternative hypotheses. Moreover, we show how CBC can be used in conjunction with empirical content analysis (e.g., levels of visual and semantic complexity).

546个被试的大型实验是怎么做的?近红外超扫描技术如何揭开群体冲突的神经机制?北京时间2020年5月29日周五上午11点,北京师范大学的马燚娜教授(Yina Ma)为大家讲解了她们组刚刚在Nature Neuroscience发表的文章。下面是报告视频。第一个是在Youtube,第二个是在youku。 Youtube:https://www.youtube.com/watch?v=4qZ7zP-BGz4Youku:https://v.youku.com/v_show/id_XNDY5MTc0MjAxMg==.html 她讲的文献如下: Within-group synchronization in the prefrontal cortex associates with intergroup conflict. Nature neuroscience https://www.storkapp.me/pubpaper/32341541 中文摘要(人工智能翻译,仅供参考):陷入群体的个人有时会失去自己的个性,冒着通常会避免的风险,以无端的敌对态度与外界接触。在这项研究中,我们确定了右侧背外侧前额叶皮层(rDLPFC)和右侧颞顶交界处(rTPJ)的组内神经同步是组间敌对性的潜在机制。我们将546个人组织为91个三对三人小组间比赛,诱导了组内亲和,并使用功能性近红外光谱仪测量了神经活动和组内同步。在组内亲和之后,个人给组内成员的钱比给组外成员的钱多,并且捐出更多的钱来击败竞争对手。组内亲和减少了rDLPFC的活动,并增加了rDLPFC和rTPJ之间的功能连接。尤其是在组外攻击期间,组内亲和还增加了rDLPFC和rTPJ中的组内同步,并且组内rDLPFC同步与组间敌对性正相关。组内同步减少前额活动可能可以解释组内联结如何导致对外界的冲动和集体敌视。
