对 MB Kovera 和 AJ Evelo 文章的评论（请参阅记录 2021-79725-001）。 Kovera 和 Evelo Kovera 和 Evelo 指出了理解社会背景对目击者行为的影响的重要性，以及由于接受者操作特征 (ROC) 分析的兴起而导致目击者研究中社会背景的下降。 ROC 分析不应削弱目击者研究中社会因素的重要性。相反，正确使用 ROC 分析应考虑社会背景如何影响目击者行为，进而影响法律体系在使用目击者证据时最大化调查员分类决策的预期效用的目标。有两个误解阻碍了 ROC 分析在目击者研究中的正确使用。第一个误解是 ROC 曲线描述了目击者的操作特征。相反，ROC 曲线描述了当调查人员使用目击者证据来判断嫌疑人有罪时调查人员的操作特征。第二个误解是 ROC 分析依赖 AUC 来评估性能。相反，EU 线应与 ROC 曲线结合使用来量化和比较研究者的表现。 ROC 分析对预期效用指标的依赖也启发了提高调查员绩效的其他可能性，而不仅仅是开发替代阵容程序。法律体系还需要考虑估计预期效用所涉及的其他参数，包括调查人员的实际操作点、有罪先验概率以及分类结果的效用。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）
Comments on an article by MB Kovera and AJ Evelo (see record 2021-79725-001). Kovera and Evelo Kovera and Evelo noted the importance of understanding social context effects on eyewitness behavior as well as social context’s decline in eyewitness research due to the rise of receiver operating caracteristic (ROC) analysis. ROC analysis should not dim the importance of social factors in eyewitness research. Instead, the proper use of ROC analysis should consider how social context influences eyewitness behavior, which in turn influences the legal system’s objective to maximize the expected utility of investigator classification decisions when using eyewitness evidence. Two misconceptions have hindered the proper use of ROC analysis in eyewitness research. The first misconception is that an ROC curve describes eyewitness operating characteristics. Rather, an ROC curve describes investigator operating characteristics when investigators use eyewitness evidence to judge suspects’ guilt. The second misconception is that ROC analysis relies on AUCs to assess performance. Rather, EU lines should be used jointly with ROC curves to quantify and compare investigator performance. ROC analysis’s reliance on the expected utility metric also enlightens other possibilities to improve investigator performance beyond just developing alternative lineup procedures. The legal system also needs to consider other parameters involved in estimating the expected utility, including investigators’ actual operating points, the prior probability of guilt, and the utilities of classification outcomes.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
