Identification refers to the automatic, subconscious psychological process in which an individual becomes like or closely associates themselves with another person by adopting one or more of the others' perceived personality traits, physical attributes, or some other aspect of their identity. The concept of identification was founded by psychoanalyst Sigmund Freud in the 1920’s, and has since been expanded on and applied in psychology, social studies, media studies, and literary and film criticism. In literature, identification most often refers to the audience identifying with a fictional character, however it can also be employed as a narrative device whereby one character identifies with another character within the text itself.

Varying interpretations of Freud's original concept of identification are found in literary and film theory traditions, such as psychoanalytic literary criticism, archetypal literary criticism, and Lacanian film analysis, and in the works of prominent theorists and critics such as Northrop Frye, Laura Mulvey, and Christian Metz. Acclaimed filmmaker Alfred Hitchcock used specific camera and acting techniques in his films to incite audience identification with his characters in order to create suspense.
