✦ Synopsis
The aim of the present experiment was to examine to what extent participants experience attempted control, cognitive load and arousal when they lie and tell the truth under lowerstakes and higher-stakes conditions. We expected both differences and similarities between truth tellers and liars. We expected that participants would experience these processes to a higher degree when they lied compared to when they told the truth (differences), but we also expected that both liars and truth tellers would be keen to make a convincing impression; and that raising the stakes would affect liars and truth tellers in a similar way (similarities). A total of 128 participants lied and told the truth during an interview (lying and truth telling was counterbalanced). Stakes were manipulated by informing half of the participants that their interviews would be recorded on videotape and would be analysed and evaluated by police officers. The predictions were supported.
