Psychoanalytic criticism analyzes literary texts to understand the unconscious desires and anxieties of the author by interpreting the text as a manifestation of the author's psyche, similar to analyzing dreams. It seeks to understand unresolved emotions and psychological conflicts in the author through the behavior of characters. Cultural criticism aims to break down hierarchies between high and low culture and analyze popular culture as well as classics. It examines political and social reasons for valuing certain aesthetic works over others. Structuralism views literature as a system of signs and seeks to understand the underlying organizational codes and patterns that regulate all literature through sociological and anthropological analysis of works in broader context.
