show faces contorted with intense emotion. But a new study
suggests that people actually don't use those kinds of extreme
facial expressions to judge how a person is feeling. Instead,
surprisingly, people rely on body cues. Hillel Aviezer, a
psychology researcher at Hebrew University of Jerusalem in
Israel, wanted to see how accurately people can read intense,

players instantly have an intense emotional reaction to winning
or losing a critical point. And usually, people have no trouble
