Research on personality is an important aspect of psychological study.The positive personality theory of positive psychology closely correlates with the personality theory of humanistic psychology.Like the personality theory of humanistic psychology,the positive personality theory focuses on the positive aspects of personality.But its research is much more profound with less emphasis on people's initiative and basically good theory.The positive personality theory criticizes drawbacks in the traditional personality psychology.In the light of such,personality is not static and the formation of personality is an individual's active construction process influenced by the congenital factors and acquired factors.The positive personality theory advocates that the psychology of personality should focus more on positive psychological personalities and virtues,which should put emphasis not only on the study of personality traits,but also on the correction of personality and the cultivation of healthy personalities to enhance the happiness of human life and to promote the harmonious development of mankind.Currently,the research of positive personality theory mainly includes studies of explanatory style theory and positive traits of personality.
