Cognitive linguistics emerged in the late 1970s, countering the prevalent methods in formalist criticism of studying language and cognition. This discipline is grounded in experiential principles, emphasizing embodied realism, which acknowledges the mind's physical grounding, the subconscious nature of thought, and the metaphorical essence of abstract ideas (Zlatev 415), thus, interconnecting language, cognition and reality within a psychological and linguistic theoretical framework. Stephen King’s Mr. Mercedes from the Bill Hodges’ trilogy depicts the psychological workings of the character of Brady Hartsfield; the narration, its linguistic expression and metaphors construct the spatiality for representation of the character’s cognition through language. As a theory of linguistics, metaphorical mapping is applied to the novel’s metaphorical representations to reveal the character’s cognition and its functioning in the context of crime/criminality.
