Abstract:Eyewitnesses are often uses in a Police investigation, the Police values their statement as important. But what if eyewitnesses are not as reliable as we think. Especially after they discussed the crime and memory conformity occurs. Self-confidence of the eyewitness play’s an important role when memory conformity occurs. To test all this we used a new technique called Reverse Correlation. This method was to see if this can be used to replicate the face of the assailant. In this study we found a main effect for memory conformity for the resemblance of the suspect and the aggressiveness level. No main effect for self-confidence. Furthermore we found an interaction for memory conformity and self-confidence for the resemblance of the suspect and the aggressiveness level. Concluded memory conformity occurs when eyewitness discuss the crime. But when self-confidence is high eyewitness will conform less than when self-confidence is low. For RC we found that it is a great method to sort of see in the participants mind trough this technique. If it could be used for real eyewitness is still to question.
