Theories of social interaction explore how individuals communicate and behave within society. These theories examine the ways people influence each other through verbal and non-verbal communication, as well as the roles of culture and context in shaping interactions. Key concepts include symbolic interactionism, which focuses on the meanings individuals attach to their interactions, and social exchange theory, which analyzes the costs and benefits of social relationships. Another important theory is dramaturgical theory, proposed by Erving Goffman, which likens social interactions to a theatrical performance where individuals present themselves in various ways depending on their audience. These theories help us understand the complexities of human relationships and the social structures that influence behavior.
