Who’s Happy? How Long We Look at Happy Faces Is in Our GenesScienceDaily (June 29, 2011) — Though we all depend on reading people’s faces, each of us sees others’ faces a bit differently.

At one end of this spectrum people with autism spectrum conditions (ASC) look less at other people’s faces, and have trouble understanding others people’s feelings.
