Bodily maps of emotions 身体的情绪地图

Abstract
Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. Here we reveal maps of bodily sensations associated with different emotions using a unique topographical self-report method. In five experiments, participants (n = 701) were shown two silhouettes of bodies alongside emotional words, stories, movies, or facial expressions. They were asked to color the bodily regions whose activity they felt increasing or decreasing while viewing each stimulus. Different emotions were consistently associated with statistically separable bodily sensation maps across experiments. These maps were concordant across West European and East Asian samples. Statistical classifiers distinguished emotion-specific activation maps accurately, confirming independence of topographies across emotions. We propose that emotions are represented in the somatosensory system as culturally universal categorical somatotopic maps. Perception of these emotion-triggered bodily changes may play a key role in generating consciously felt emotions. 论文摘要 情感通常都能被我们的身体所感知,身体的反应也常常触发情绪体验。于是我们开发了一个勘测型自行报告的工具,用来研究身体感觉和不同的情绪之间的联系。在5个试验中,研究人员向参与者(n=701)展示了两个身体轮廓图,并且要求他们把观看情绪词语、故事、电影或面部表情时其自身感到的活动增加或减少的身体区域用彩色标示在图上。西欧人和与东亚人受试者的映射图是一致的,这些受试者分别说他们自己本族的语言,这提示情绪身体感觉可能是在文化上具有普遍性。统计分级器精确的区分了情感激活作用在图形上的位置,确定了哪些图形是独立的情绪。我们认为在躯体感觉系统上的那些情绪是可以通过分类躯体来区分。这些触发情感的身体改变使那些情感被人体自发的察觉起到了重要的作用。
