Subjects video chat with each other. In one treatment subject A sees her own image in a small window in the corner of the chat, and in the other treatment (the control) there is no small window and she sees only the chat partner.
Subject B is not told about the two treatments and is simply asked to report how attractive subject A is. We want to know whether attractiveness is higher in the self-image treatment versus the control treatment.
This gets at a few different issues but the one I am curious about is this: do people know what it is about them that makes them attractive to others?
Also, we would want to track eye movements during the chat.
