Abstract:Over the past years, deception detection research has mainly focussed on the deception detector, but not on the one trying to deceive. Studies have uncovered some results about the effects of the relations between the liar and the detector, characteristics, questioning methods, knowledge of deception, and more. Yet, the influence a liar has on the deception detection is unknown. Studies have pointed out that people try to control their behaviour while deceiving others (Interpersonal Deception Theory) and that this leads to differences in how people move when they deceive (Rigidity Effect). Yet, it is not researched how capable people are in controlling their own behaviour and if there is a difference between people in this capability of control. When participants deceived others, they significantly moved their head and overall body less compared to when they were truthful. A cluster analysis showed that there are more individual differences in truthful behaviour compared to deceitful behaviour, which is in line with finding a rigidity effect. Those who performed better in the poker game were more capable deceivers because they had less truthful-deceitful moving contrast on which a lie detector can base a decision
