I have been focusing more and more on trying to connect with my left eye to others left eye. Many times while trying to see the persona in the left half of others I notice on my periphery more activity on the right half of face on others. It is almost a flash but the left side does not seem to express as much of these as the right. There are many people that do use the left side in an animate way but it seems still less active than their right for the most part.
It still takes some effort and imagination to see the persona exhibited in the left side. When I glance at the right the persona is there. The left takes some time and I am not always successful. I see the elements of the face on the left but not the person.
