Abstract:The purpose of this study was to investigate in a laboratory setting whether the Concealed Information Test (CIT) can detect guilty people on the basis of electro-dermal measures. Participants were randomly assigned to one of two groups, where they either had to take an active part in a mock crime or watch a video with crime relevant information as an informed innocent bystander. For our experiment, we chose a 2x2x2 mixed subjects design, which consisted of two stages. Participants were tested either immediately or five days after the experiment on crime relevant and irrelevant trials. Results could demonstrate a significant effect for a different responsiveness on guilty and innocent trials. Yet, there was no main effect found for the factors condition or time. Also, an interaction effect between trial type and time could be shown in the group informed innocents. These findings suggest that the CIT is a valid tool to test for guilty feelings.
