Abstract:
Police officers often face critical incidents involving armed offenders, requiring the use of force to ensure safety. Eyewitness accounts, including those from officers, are crucial in the justice system but can be unreliable. Techniques such as self-authored statements and structured interviews are used to gather information, but their efficacy in high-stress situations is unclear. Previous research suggests that heightened arousal during memory encoding enhances recall, particularly for central details. This study compares recall methods (statements vs. interviews) for police officers in high-stress versus no-stress situations, focusing on central and peripheral event details. Officers participated in a simulated high-stress incident, providing memory data through both methods. Overall, no significant difference was found in memory scores between the techniques. However, analysis revealed significant differences favoring structured interviews for peripheral information. Recall that central information remained consistent across methods. These findings highlight the need for careful methodology when examining memories formed in stressful contexts.
