The purpose of the present study was to examine whether or not the eyewitness suggestibility effect might be obtained with a recognition memory and a source-monitoring test, when an original event consisted of many pictures. In this source-monitoring test subjects identified the source of their memories. Results showed that the suggestibility effect was obtained in the recognition memory but not in the source-monitoring test, suggesting that misleading postevent information did not impair memory of the original event. The results also indicated that the eyewitness suggestibility effect might be caused by misled subjects' decision rather than their integrated memory representation.
