To Catch a Liar: Challenges for Research in Lie Detection Training

Can we train people to detect deception? It is the contention of this article that communication scholars should learn how to train law enforcement professionals on how to detect high stake lies, like those faced by police, judges, customs officials, immigration officials, and so forth. It is proposed that in order to know whether we can train or should bother to train people to detect deception, each training study must meet 6 challenges: (1) relevance, (2) high stakes, (3) proper training, (4) proper testing, (5) generalizability across situations, and (6) generalizability over time. Our quantitative review of the literature suggests that training does significantly raise lie detection accuracy rates. Meta-analytic findings indicate a mean effect size of r = .20 across 20 (11 published studies) paired comparisons of lie detection training versus the control group (i.e., those without some type of training). It should be noted that the majority of the studies that attempt to train lie detectors fall short on many of the above challenges. Current research in lie detection training may actually underestimate the ability to train lie detectors due to the stimulus materials employed in most experiments.

Exercise and mental health: it's just not psychology!

Exercise has been suggested as an effective adjunctive treatment for a range of mental health conditions. In this study, we explored the perceptions of exercise held by course directors of doctoral training programmes in clinical psychology in England. Given the exploratory nature of the study, we used a qualitative design incorporating semi-structured interviews. Although most participants held favourable attitudes regarding exercise, this was related more to exercise being seen as a positive lifestyle activity that is worth encouraging, rather than exercise being recommended as an adjunctive treatment for mental health problems. Inductive analysis identified four themes that underpinned such a response: inconsistent positions on the evidential criteria used to evaluate the role of exercise, which masked themes regarding the perceived 'simplicity' of exercise interventions, a practical adherence to a mind-body dichotomy, and the incompatibility of exercise with traditional models of understanding and treating clinical conditions. The barriers we have highlighted will continue to hinder the consideration of exercise as a common therapeutic adjunct at present. Although further research is required to examine the relationship between exercise and mental health, consideration must also be given to how such research should be disseminated to mental health professionals.
