Meant to convey some kind of sentiment or empathy to another person, "I feel your pain" means that you understand someone or their situation. But what if individuals existed that actually physically felt other people’s pain? That when a woman sees a child hit their head on a grocery store floor, she herself falls to the ground feeling the same sharp pain in her head?

 

He fell backwards and hit his head - just smack. And I went to run. And all of a sudden, my eyes went blurry, and I was down on my knees on the thing before I could get to this kid. And I’m just like, this child, he needs help. And my head hurt so bad that I basically, you know, was like crawling to try to get to the kid.

How could this happen? How could someone physically embody someone's feelings? In fact, scientists have found that this phenomena occurs because of the way that we all develop systems of “self” and “other” in order to function in our social world. Researchers have also discovered that in certain places in the brain, and at specific time points in development, "self" and "other" become crossed and mixed, creating strange and fantastical situations. This leads us to the lesson that will be demonstrated throughout this feature:

 

In order to understand the simulation of others’ perspectives, we need to further understand how they arise during childhood.
