Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. The heatmaps reveal bodily sensations associated with different emotions using a unique topographical self-report method. The participants 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.
