Social psychology is the branch of psychology that studies how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. Different theoretical approaches have been developed to explain social behavior from various perspectives. These approaches help psychologists understand why individuals behave differently in social situations and how social interactions shape human behavior. The sociocultural approach emphasizes the influence of society, culture, social norms, traditions, and social roles on individual behavior. According to this approach, people's attitudes, beliefs, and actions are largely determined by the cultural environment in which they live. Social norms guide acceptable behavior, while values and customs influence interpersonal relationships. Differences in behavior across cultures, such as individualistic and collectivistic societies, are explained through this perspective. The evolutionary approach argues that many aspects of social behavior have developed through the process of natural selection. Behaviors
