Tests conducted at the University of Pennsylvania's Psycho1ical Laboratory showed that anger is one of the most difficult Emotions to find out from facial expressions. Professor Dallas E. Buzby confronted 716 students with pictures of extreme1y angry persons， and asked them to identify the emotion from the facial expression。 Only two percent made correct judgments. Anger was most frequently judged as“pleased”. （重庆MBA培训）

And a typical reaction of a student confronted with the picture of aman who was mad was to classify his expression as either ‘bewildered’，‘quizzical’，or simply‘amazed’．Other studies showed that it is extremely difficult to tell whether a man is angry or not just by looking at his face. The investigators found further that women are better at finding out anger from facia1 expressions than men are. Paradoxically，they found that psychological training does not improve one’s ability tojudge a man’s emotions by his expressions but actually hinders it． For in the university tests， the more courses the student had taken in psychology， the poorer judgment score he turned in.
