Research Abstract

To investigate how the emotional experience influence the accuracy of the ear-witness identification, two arousal conditions(one was neutral and the other was emotional)were prepared. The identification of the target voice was done after a week from the ear-witness. The lineup consisted of six voices including the culprit. The results showed that the correct identification in the emotional condition was inferior to that of neutral
