자기기입식 면담과 오정보가 목격자의 회상 정확도에 미치는 영향

초록

This study aimed to examine the effects of the Self-Administered Interview (SAI) and misinformation on eyewitness memory. A total of 115 participants were randomly assigned to a 3 (initial memory recall: SAI, free recall, control) × 2 (misinformation: present, absent) between-subjects experimental design. After watching a mock crime video, participants performed initial memory recall according to their assigned condition. One week later, post-event information was provided, and their recall accuracy was measured. The results showed that initial memory recall through SAI led to significantly higher recall accuracy than the other conditions. However, when misinformation was presented, the difference in recall accuracy between the SAI and other conditions was not statistically significant. Further analysis revealed that, in the absence of misinformation, the SAI condition resulted in significantly greater accurate information recall and total recall quantity compared to other recall conditions. This study suggests that SAI is an effective tool for securing eyewitness statements and preserving memory in early investigations, demonstrating its utility even in limited investigative environments. Finally, the implications and limitations of the study are discussed.
