Psychological thriller- literary devices and techniques

Stream of consciousness - a literary technique which seeks to describe an individual's point of view by giving the written equivalent of the character's though processes. In psychological thrillers, the narrative tries to manifest the character's psyche through word usage, descriptions, or visuals.

First person narrative - a literary technique in which the story is narrated by one or more of the characters., who explicitly refers to themselves in the first person, that is, "I". This direct involvement that the characters have with the story in turn makes the audience more involved with the characters themselves, and thus able to understand the mechanics of the characters' minds. This technique is often paired with the concept of unreliable narrator.

Back story - the history behind the situation extant to the start of the main story. This deepens the psychological aspect of the story since the reader is able to more fully understand the character; more specifically, what the character's motivations are and how his past has shaped his cognitive perceptions.
