I am arguing that I did not differentiate the left and right half of other people's faces as I grew up and that it was reflected in how I used myself. I saw the right side as the persona of others and I am in my movement picture right sided. A recent article on a popular science site talks about the connection of seeing and feeling pain and empathy to the other person. It does not specify any differences in the sides of the person but links the seeing and empathy.
If there is pseudoneglect of the left side of the other person's face would I have decreased developmental control of my own? I feel in the own use of the left side of my face is largely the inability to relax what I already do.
