Symbolic interaction is in sociology, a theoretical approach that focuses on social reality as constructed through the daily interaction of individuals and that places strong emphasis on the role of symbols (gestures, signs, and language) as core elements of this interaction.
Symbolic interaction is a sociological way of approaching social psychology. It emphasizes the part played by language, gestures and other symbols of social interaction in our conscious attempts to form ourselves and our world and it regards our human qualities as the products of that social interaction.
