Princeton, New Jersey – Facial expressions are often considered the most precise indicator of emotion in a person, but new studies indicate that our reliance on the face to read emotion in another person is likely to lead us astray. Hillel Aviezer, neurophysicist at Jerusalem University, conducted a study of Princeton University students, which involved showing them pictures of a group of professional tennis players right after they had either won or lost a tennis match. The students were split into three groups of 15 each, and were then showed pictures of the tennis players. The first group of students saw the head-to-toe pictures of the tennis players, the second just the bodies, and the third just the faces. Each student was instructed to rate the emotions in the players from 1 to 9, with 1 being negative and 9 being positive, and 5 neutral. The third group of students, who only saw the athlete’s faces, had trouble correctly identifying the emotion of the player, while the other two groups were correct nearly every time. While this does not mean that facial expressions are not useful in determining emotions, it does indicate that body language plays a significant role in determining the mental disposition of an individual.
