Including research on: Verbal and nonverbal detection of deception (Aldert Vrij; Lucy Akehurst; Sam Mann; Sharon Leal; Jackie Locke); Polygraph (Sharon Leal); Criteria based content analysis (Lucy Akehurst; Sabine Quandte); Malingering in medico-legal contexts (Simon Easton).

Research example

"How to catch a liar".  Aldert Vrij, Samantha Mann and Sharon Leal are all involved in a detection of deception project which investigates the effects of increasing cognitive load in an interviewee. They anticipate that putting extra demands on an interviewee will make lying more difficult leading to nonverbal and verbal cue leakage, thus facilitating deception detection.
