In the past few decades, the popular belief in the area of organizational behavior and psychology has been that        workers are better workers. However, new research at the University of Alberta shows that sad workers are more        .
Psychologist Dr. Robert Sinclair recently conducted a series of four studies    the effects of experimentally induced ( 诱发的 ) happiness versus sadness on work         by asking the participants to build circuit boards. In the first study, sad people committed         few errors than did happy people, but there was no difference in the number of boards        .
In similar studies Sinclair found the same results along with the evidence that happy people might not         as much energy to the task in order to maintain their happy moods ---- they considered that task as something that might detract from their         feelings.
These findings are not surprising, said Sinclair, since there has been a growing body of literature in the area of social psychology        that sad moods lead to more calm lengthy intent consideration and often, more thought or accurate judgments. So it’s important for organizations to take into account the      of their employees. It seems it could be beneficial to creating situations that lead people to believe that performing their jobs will cause them to feel good.
