The visual field for human beings is the only place where they find a relatively unfiltered reflection of themselves. Mirrors for many people are a place to connect with themselves, though it’s not always a good connection and it can be hard to look in the mirror for any length of time without being accused of being a narcissist.
But, let’s not get too far ahead of ourselves. What we think we know about how people construct themselves is frequently an internal image that is not congruent with the external image. An example of this can be if one were an overweight teenager and now may be in shape, but still see the body in the earlier time and place and not able to acknowledge the difference. I see this frequently in people who work out and may be in great shape, though they still see the skinny or fat little kid.
Our work in this area is to alter that discordancy so that they are closer to each other, and hopefully to skew it in the direction of the present time physical world.
