Sažetak
A series of studies has shown that people are not good at assessing the veracity of others’ behavior, mainly because of the unreliable and weak behavioral signs of deception. Therefore, some authors propose a more active approach to lie detection, one which is based on imposing additional cognitive load on the evaluated person. Because the cognitive system of liars is already burdened with various tasks required for successful lying, such a procedure should represent greater difficulties to liars compared to truth tellers. This should lead to increased behavioral differences between the two groups (more blinking, more speech disturbances, etc.). The aim of this study was to verify the hypothesis about facilitated assessment of others’ statements when they are given under additional cognitive load. Study participants (N=73) watched videotaped interviews of other students who were telling the truth or lying about their work experience. One group of participants watched videos of students who gave their answers while observing themselves in a mirror, while the other group watched videos filmed without the mirror. The participants’ task was to assess: 1) whether the videotaped person was telling the truth, 2) how nervous the person appears to be, and 3) how intensely is the person thinking. The results did not confirm the research hypotheses - for the assessment of veracity, neither the main effects of the video type and mirror use, nor their interaction were significant. Contrary to expectations, there was a significant main effect of the video type on thinking intensity estimates: on average, observers gave higher estimates when watching videos of truth tellers compared to those of liars. Regarding the impressions of nervousness, significant interaction of video type and mirror use emerged. On average, liars were perceived as more nervous than truth tellers, but only in a situation without a mirror.
