Why engineers yawn less than psychologists | Science | The Guardian: "Psychologists have shown that a phenomenon called 'contagious yawning' is strongest in people who are more empathetic and have a more developed sense of social awareness. Researchers at the University of Leeds covertly watched 40 psychology students and 40 engineering students yawning contagiously. The students thought they were sitting in a waiting room before an experiment, but in reality their reactions were being observed while someone else in the room yawned 10 times. On average, the engineering students yawned 1.5 times in response, while the psychology students yawned 5.5 times. The two groups also differed in how well developed their 'theory of mind' was - that is, their ability to appreciate the mental state of others."
