Abstract: Psychological researches tend to put more emphasis on human's natural attributes than social attributes. In fact, psychology should, based on the comprehensive understanding of human nature, focus on humane concern and respond to the specific social reality, such as personal happiness, social justice, and world peace. Some studies argue that personal happiness can be divided at the psychological and subjective level. Studies show that demographic variables, personality characteristics, goals and economic status all have impressive effect on subjective happiness. In terms of social justice, researchers argue that lower-class people, who are more dependent on social justice, are more likely to have a feeling of social inequality than higher-class people. Some policies aiming to reducing social constraint, promoting the sense of control can enhance the sense of equality among lower-class people. In terms of the world peace, great progress has been achieved in the studies on love and hate, truth and reconciliation, comprehension and coexistence. And there is still much to be explored in combining humane concern with social responsibility in psychological researches.
