Canter, David V., Ioannou, Maria, Youngs, Donna E. and Chungh, Gemma (2015) Person Perception Aspects of Judgments of Truthfulness in Public Appeals. Psychiatry, Psychology and Law, 23 (4). pp. 547-562. ISSN 1321-8719

Although detection of deception accuracy rate has been researched extensively, the person perception components that are the basis for these judgments remain unclear. To explore this, 30 academics' person perceptions, as well as truthfulness judgment, of the individual presenting a televised appeal were measured using a 14-item scale. Twelve appeals (6 genuine and 6 false) for information regarding the whereabouts of a missing relative, or for information to apprehend the person who murdered their relative, were used. The person perception scale consisted of (1) global, abstract judgments (open, deceptive, genuine, trustworthy, and emotional) and (2) behavioural indices (facial pleasantness, facial animation, arousal, tension, involvement, verbal; consistency, plausibility and directness, and vocal certainty). Multiple regression identified person perceptions of openness, (non)deceptiveness, genuineness, trustworthiness, and verbal plausibility as significant predictors of truthfulness judgments. Future research should now explore the relationship of these person perception components of truth judgments to the accuracy.
