ABSTRACT

This chapter focuses on different aspects of a police officer's deception detection. It reviews research examining police officers' beliefs on cues to deception, followed by a summary of what is known about police officers' ability to detect deception, and how they actually go about trying to detect deception. The chapter argues that why the police officers' think the so-called information-gathering interviewing technique is a better approach to detect deception than the more traditional confrontational approach. It highlights three new and promising extensions of the information-gathering approach, first and foremost aimed at eliciting diagnostic cues to deception: the cognitive load approach, the use of unanticipated questions and the strategic use of evidence approach. The psycho-physiological approach to detect deception has a long history, and one of the first polygraphs used in legal settings was constructed by William Marston in the United States for interrogating suspected spies during the First World War.
