This study assessed the relationship between Eyewitness Accuracy regarding a person met under conditions of high stress and performance on a standardized, neutral test of memory for human faces.
Fifty-three U.S. Army personnel were exposed to interrogation stress. Forty-eight hours later, participants were administered the Weschler Face Test and then asked to identify the one interrogator who they had encountered 48 h earlier.
A significant positive relationship was observed between performance on the Weschler Face Test and performance on the Eyewitness task. Inaccurate eyewitnesses exhibited more False Negative errors when performing the Weschler Face Test.
Trait ability to remember human faces may be related to how accurately people recall faces that are associated with highly emotional circumstances. Detection probability methods, such as ROC curve analyses, may be of assistance to forensic examiners, the police, and the courts, when assessing the probability that eyewitness evidence is accurate.
本研究评估了在高压力条件下遇到的人的目击证人准确性与标准化中性人脸记忆测试表现之间的关系。
53名美国陆军人员承受审讯压力。48小时后，参与者接受韦氏面部测试，然后被要求辨认出他们在48小时前遇到的一名审讯人员。
在韦氏面部测试的表现与目击证人任务的表现之间观察到显著的正相关关系。不准确的目击证人在进行韦氏面部测试时表现出更多的假阴性错误。
记住人脸的特质能力可能与人们回忆与高度情绪化情境相关的面孔的准确程度有关。在评估目击证人证据准确的可能性时，诸如ROC曲线分析等检测概率方法可能对法医、警方和法庭有所帮助。
