Estereótipos, mentiras e videotape: estudos experimentais sobre a acurácia na identificação da mentira

Abstract

The aim of this study is to experimentally investigate the lying behavior. Three hypotheses have been advocated. The first concerns the kind of cues which are conducive to identifying a lie (auditory and/or visual). The second is about the degree of accuracy in identifying mistakes among social categories. Lastly, the third relates to stereotypes effects and proposes a different pattern structure with regard to mistakes made by participants about lies presented by individuals from the social groups under investigation. The first assumption did not lead to any differences in lie identifying when the clues are either visual and auditory or visual only. It has been found that the social category depicted in the scene holds little significance. The third group of assumptions, on its turn, made it clear that stereotyped beliefs were not strong enough to distort judgment and thus influence the mistakes.
