An article on quartz about An Atlas Of The Human Body That Maps Where We Feel Emotions pointed me to this scientific article by Finnish researchers on using heat maps to visualize the experience of emotions.
The Quartz article summarizes the study as follows:
Their results, reported in the Proceedings of the National Academy of Sciences, produced consistent heat maps that were statistically unique for each emotion, and reproducible among the subjects, who were of Finnish, Swedish, and Taiwanese. Their conclusion is that the emotional signatures in different parts of the body are “culturally universal” and are tied to biological systems, rather than triggered by what people have learned to think based on common language phrases, such as “having butterflies in the stomach.”
I would have expected something like that but its nice to have another validation of our common humanity. And the heat map is a neat visual tool of sharing it.
