A team of researchers worked with more than 700 participants in Sweden, Finland and Taiwan to draw a heat map of what areas of the human body are effected with certain emotions. Participants viewed emotion-laden words, videos, facial expressions and stories, and self-reported the body parts that felt different after being exposed to the emotion stimulus.
Based on the changes reported by the participants, two computer generated silhouettes were colored to show increased bodily sensation and conversely, decreased bodily sensation.
Having several participants over different geographic regions means researchers can have a better idea, free of cultural and regional biases towards various emotions.
It is interesting to see how love and happiness are similar, even more so, how very compatible pride and anger seem to be.
