The Evolution of Research of Investigative Interviewing to Detect Deception and How Evidence-Based Research is Being Implemented in Law Enforcement and National Security Training Programs

This conference workshop presentation provides an overview of new cognitive tools of lie detection and the elicitation of information which can be used with individuals and groups, and how they are being integrated within law enforcement training programs. The cognitive approach to verbal lie detection has been shown to elicit verbal cues to deceit and facilitate lie detection. A study evaluating a training program in this approach showed that police detectives trained in this approach correctly classified 74 percent of the truthful or guilty mock suspects they interviewed, whereas untrained police detectives achieved 59 percent accuracy. Presenters explain the cognitive lie detection approach, which utilizes an information-gathering interview style which has shown to result in more accurate information and true confessions, and in fewer false confessions than an accusatory interview style. The presentation will demonstrate the technique and show how law enforcement officers can easily utilize this method in their interview protocols.
