The purpose of this study was to investigate how the accuracy eyewitness memory is affected by confidence, scene emotionality, and susceptibility to misinformation. Participants included 90 college students who were presented with scenarios which depicted characters in positive, negative, and neutral situations. From completing a filler activity and a survey following the scenario, information was obtained about participants' confidence in what they read, memory accuracy, and susceptibility to misinformation. Whether a person experienced positive, negative, or neutral emotion was shown to impact how many false memories a person had about an event. Results indicated that the higher the level of confidence the subject had in their memory, the lass likely they were to yield to misinformation and the more likely it was that their answers were correct. In both the positive and negative conditions, high levels of confidence in ability to accurately answer questions about an event were associated with fewer false memories.
