Discourse refers to any written or spoken form of communication more than a sentence, e.g., narratives.
In psychology, discourse refers to the study of language use in social contexts, including how people use language to construct meaning and how language shapes and reflects social realities. It is a broad term that encompasses various forms of communication, including spoken and written language, as well as nonverbal cues such as gestures and facial expressions.
Examples of discourse analysis in psychology may include examining how people use language to negotiate power dynamics in social interactions, analyzing the language used in political or media discourse to shape public opinion, or studying how people use language to construct their identities and social roles.
Discourse analysis is a useful tool for understanding the social and psychological dimensions of communication, and can provide insights into how language use reflects and shapes social attitudes, beliefs, and behaviors.
