This chapter focuses on facial expressions as key indicators of emotion in communication. It explains how emotions can unintentionally appear through facial cues, known as emotional leakage, and how recognising these signals improves understanding, communication accuracy, and interaction effectiveness.
Facial Image Comparison Program (Impostor Detection) equips participants with practical skills to analyse facial features, identify impostor indicators, compare travel or identity images, and support frontline security screening through behavioural observation, facial recognition principles, and investigative assessment techniques.
The Rapport-Based Interviewing Model, influenced by Clifford Stott, emphasises building trust, empathy, and communication to encourage cooperation. It supports investigators in reducing resistance, improving information quality, and fostering voluntary disclosure, making it highly effective in interviews, interrogations, and sensitive investigative contexts.
The Alan Elangovan ALAN Model integrates behavioural analysis, structured questioning, and situational awareness to guide investigations. It emphasises adaptive thinking, layered information gathering, and real-time assessment, enabling investigators to detect deception, interpret intent, and make precise, evidence-based decisions in complex investigative environments.
