OBJECTIVES Eyewitness research has adapted signal detection theory (SDT) to investigate eyewitness performance. SDT-based measures in yes/no tasks fit well for the measurement of eyewitness performance in show-ups, but not in lineups, because the application of the measures to eyewitness identifications neglects the role of fillers. In the present study, we introduce a SDT-based framework for eyewitness performance in lineups-Multi-d' Model. METHOD The Multi-d' model provides multiple discriminability measures which can be used as parameters to investigate eyewitness performance. We apply the Multi-d' model to issues in eyewitness research, such as the comparison of eyewitness discriminability between show-ups and lineups; the influence of lineup bias on eyewitness performance; filler selection methods (match-to-description vs. match-to-suspect); eyewitness confidence; and lineup presentation modes (simultaneous vs. sequential lineups). RESULTS The Multi-d' model demonstrates that the discriminability of a guilty suspect from an innocent suspect is a function of discriminability involving fillers; and underscores that the decisions that eyewitnesses make in lineups can be regarded from two perspective-detection and identification. CONCLUSIONS We propose that the Multi-d' model is a useful tool to understand decisionmakers' performance in a variety of compound decision tasks, as well as eyewitness identifications in lineups.

基于新信号检测理论的阵容中的目击者性能框架。

目的目击者的研究已经适应了信号检测理论(SDT)来研究目击者的表现。在是/否任务中,基于SDT的度量非常适合于显示中的目击者性能的度量,但不适用于阵容中的,因为将度量应用于目击者识别时会忽略填充物的作用。在本研究中,我们为阵容Multi-d'模型中的目击者表现引入基于SDT的框架。方法Multi-d'模型提供了多种可分辨性度量,可以将其用作调查目击者表现的参数。我们将Multi-d'模型应用于目击者研究中的问题,例如对演出和阵容之间的目击者辨别力进行比较;阵容偏见对目击者表现的影响;填充物选择方法(匹配描述与 猜中匹配);目击者的信心;和阵容展示模式(同时还是顺序的阵容)。结果Multi-d'模型表明,有罪嫌疑人与无罪嫌疑人的可辨别性是涉及填充物的可辨别性的函数。并且强调了目击者在阵容中做出的决定可以从侦查和识别两个角度来考虑。结论我们认为Multi-d'模型是了解决策者在各种复合决策任务中的表现以及阵容中目击者识别的有用工具。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。该模型表明,有罪嫌疑人与无罪嫌疑人的可辨别性是涉及补白者的可辨别性的函数;并且强调了目击者在阵容中做出的决定可以从侦查和识别两个角度来考虑。结论我们认为Multi-d'模型是了解决策者在各种复合决策任务中的表现以及阵容中目击者识别的有用工具。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。该模型表明,有罪嫌疑人与无罪嫌疑人的可辨别性是涉及补白者的可辨别性的函数;并且强调了目击者在阵容中做出的决定可以从侦查和识别两个角度来考虑。结论我们认为Multi-d'模型是了解决策者在各种复合决策任务中的表现以及阵容中目击者识别的有用工具。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。该模型是了解决策者在各种复合决策任务中的表现以及阵容中目击者识别的有用工具。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。该模型是了解决策者在各种复合决策任务中的表现以及阵容中目击者识别的有用工具。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。
