Debrief

Thank you for participating in this study. The purpose of this study is to examine the relationship between people's veracity judgement (how truthful they perceive someone to be), uncertainty and confidence and how this changes after watching a number of videos. The potential differences between genders will also be considered. We predict that participant veracity judgement responses will become more consistent as the number of videos viewed increases.
