Echoing the emotions of others: empathy is related to how adults and children map emotion onto the body.

Empathy involves a mapping between the emotions observed in others and those experienced in one's self. However, effective social functioning also requires an ability to differentiate one's own emotional state from that of others. Here, we sought to examine the relationship between trait measures of empathy and the self-other distinction during emotional experience in both children and adults. We used a topographical self-report method (emBODY tool) in which participants drew on a silhouette of a human body where they felt an emotional response while watching film and music clips, as well as where they believed the character in the film or performer was feeling an emotion. We then assessed how the degree of overlap between the bodily representation of self versus other emotions related to trait empathy. In adults, the degree of overlap in the body maps was correlated with Perspective Taking. This relationship between cognitive empathy and degree of overlap between self and other was also found with children (8-11 years old), even though children performed worse on the task overall. The results suggest that mapping emotions observed or imagined in other's bodies onto our own is related to the development of empathy.
