Abstract
The Effects of Postevent Information and Repetition on The Eyewitness' Memory Performance and Phenomenological Awareness The aim of this study is to examine the effects of postevent information on the eyewitness' memory under different circumstances. In the studying phase of the two experiments subjects viewed slides depicting a criminal event and then received a narrative containing misleading information about some items in the slides. One of the differences between two experiments is the postevent narrative. One that is used in the first experiment has four different versions, which involves misinformation with repetition once or three times, and true information with repetition once or three times. The other version of narrative which used in the second experiment contains all of the conditions of the first experiment. Another difference is that experiment two involves a testing procedure that is repeated three times. In the testing phase of two experiments subjects answered a recall and a recognition test, then all subjects gave remember/know decisions for their answers on the recall and the recognition tests. A 2 (postevent narrative) X 2 (critical item repetition) for the first experiment and 2 (critical item type) X 2 (critical item repetition) X 3 (repeated retrieval) for the second experiment ANOVA was used to analyze the data. Results indicated that misinformation effect obtained in recall and recognition. Critical item repetition was led misinformation to have been more accessible. The more accessible misinformation the more confidence of remembering the false item was obtained and results also indicated that misinformation effect increases through repeated testing. False memory may arise through repeated retrieval. All of the results were in line with literature. Key Words: Eyewitness memory, misinformation accessibility, phenomenological awareness, postevent information.
