A free talk his talk by Professor Aldert Vrij, University of Portsmouth, in the Centre for Forensic and Investigative Psychology Seminar Series
This talk provides an overview of a cognitive approach to verbal lie detection. The core of the approach is that investigators can magnify the difference in cognitive load that liars and truth tellers experience through specific interventions, resulting in liars displaying more diagnostic cues to deception. A discussion of the cognitive lie detection approach, which consists of three techniques, (i) imposing cognitive load, (ii) encouraging interviewees to say more, and (iii) asking unexpected questions, is followed by a meta-analysis of the available cognitive lie detection research examining whether the approach improves the ability to distinguish truth tellers from liars.
