Abstract:There have been many studies in the field of lie detection where the focus has been on the exact moment of telling a lie. The present study focused on the moment leading up to the lie: the intention of deception. This relatively new area of research within the field of lie detection is interesting because in real world situations a person would not constantly tell lies, but only at certain questions. Before the actual lie is told, the speaker has the intention to deceive: the truth is spoken but the speaker has the intention to deceive at specific questions. An experiment was performed that examined the possibility of measuring increased cognitive load during the intention of deception (compared to truth-telling) by means of measuring skin conductance. This study also attempted to increase the differences between truth-telling and lying by adding a cognitively demanding task to the experiment. The results showed an increased amount of SCR’s in the truth condition compared to the intention condition, suggesting that truth-telling is more cognitively demanding than having the intention to deceive. Adding a cognitively demanding task did not significantly influence the differences in skin conductance between truth-telling and lying. The results suggest that the moment leading up to a lie can be interesting and several suggestions are given for future follow-up research.
