Abstract
Despite difficulties in interpretation, nonverbal communication is especially important in forensic settings, such as police investigations. Three distinct clusters of personality disorders have been outlined as being associated with criminal behaviour. Understanding the similarities and differences between these personality clusters and nonverbal communication could help investigators look for key signs of psychological distress or deception. The current research proposes a novel approach to nonverbal communication: behaviour sequence analysis (BSA). An application of this approach is outlined to investigate whether criminals with different personality types are better at concealing emotions and nonverbal communication when being interrogated. The results indicate that while sequences are generally similar across clusters, individuals from different personality clusters exhibit unique patterns. This research provides an initial step towards a new area of nonverbal communication research and application, which could be used in future research to highlight increased possibility of deception or concealment of emotion.
