In literature, psychological fiction (also psychological realism) is a narrative genre that emphasizes interior characterization and motivation to explore the spiritual, emotional, and mental lives of the characters. The mode of narration examines the reasons for the behaviors of the character, which propel the plot and explain the story. Psychological realism is achieved with deep explorations and explanations of the mental states of the character's inner person, usually through narrative modes such as stream of consciousness and flashbacks.
