Positive emotions and adaptive behaviors play in leading a satisfying and productive life. Previously, psychologists thought that the study of positive emotions was less meaningful than that of negative emotion and serious psychological disorders.
However, recent research has concluded that an awareness of positive psychological traits can be significant. By increasing a sense of autonomy, self-efficacy, and personal control, as well as avoiding anxiety and fear of failure through contingent positive reinforcement, people will perform better and be more productive.
