I spotted an interesting article over on Science Daily looking at how psychologists help members of law enforcement distinguish between the truth and lies. Researchers at UCLA recently conducted research on the subject in addition to analyzing 60 studies on deception in order to develop recommendations and training for law enforcement. The results of their research were published in the April issue of the American Journal of Forensic Psychiatry.
Body language is often used as a way to determine if a person might be lying. A few of the potential red flags the researchers identified that might indicate that people are being deceptive include:
- Being vague; offering few details
- Repeating questions before answering them
- Speaking in sentence fragments
- Failing to provide specific details when a story is challenged
- Grooming behaviors such as playing with hair or pressing fingers to lips
Lead researcher R. Edward Geiselman suggests that while detecting deception is never easy, quality training can improve a person's ability to detect lies. "Without training, many people think they can detect deception, but their perceptions are unrelated to their actual ability. Quick, inadequate training sessions lead people to over-analyze and to do worse than if they go with their gut reactions."
