Title ANALYZING SPEECH PATTERNS OF PSYCHOPATHIC SERIAL KILLERS: A FORENSIC PSYCHOLINGUISTIC APPROACH TO DECEPTION DETECTION

Author(s) Afifa Sarfraz

Abstract This study investigates the speech patterns of psychopathic serial killers to identify the linguistic and nonverbal strategies used for deception and manipulation. Using a mixedmethod approach grounded in Mark McClish's (2012) Statement Analysis framework, interviews of 10 psychopathic serial killers were analyzed. The interviews, sourced from YouTube, were transcribed and observed to examine linguistic and behavioral indicators of deception. Additionally, the Linguistic Inquiry and Word Count (LIWC) tool was employed to ensure validity and provide quantitative insights into the psychopathic linguistic profile. The findings reveal that psychopathic serial killers strategically use language to achieve their hidden motives. They demonstrate emotional detachment, frequently blame external factors, and avoid expressing remorse for their actions. High use of figurative language and ambiguous statements signals deceptive intent while their speech often reflects control and dominance. LIWC analysis highlights low affiliative language, high power-related terms, and moderate authenticity scores, reinforcing their manipulative tendencies. Nonverbal behaviors, such as smiling and smirking during discussions of their crimes, suggest enjoyment and a lack of moral regard. However, this research contributes to understanding the distinct linguistic and behavioral traits of psychopaths, emphasizing the need for awareness regarding psychopathy's link to recidivism. While this study focuses on Western psychopathic serial killers, its findings underline traits transcending cultural boundaries. Future research on psychopaths who are involved in crimes within Pakistan is necessary to generalize and validate these findings. This study aims to create awareness and inform strategies for identifying and managing individuals with psychopathic traits.
