Collaborative Research: Showups vs. Lineups: A Comparison of Two Identification Techniques

在目击证人识别领域，很少有研究比较对峙(一人识别)、同时列队(所有列队成员同时查看)和顺序列队(列队成员一次查看一个)来确定哪一个最准确。目前的研究涉及一系列实验，参与者将首先观看多名肇事者闯入存储单元的舞台视频，然后完成一次对决、顺序排列和同时排列，每一次都涉及不同的嫌疑人。最后，参与者将表明他们对自己的决定的信心，并完成关于操纵和见证体验的其他问题。目前的研究有三个目标：比较单一研究中摊牌和阵容之间的辨认准确性；开发改进目击者辨认的技术；以及使用正式的计算模型促进对摊牌和阵容辨认过程中潜在记忆和决策过程的更好理解。这项研究的重点是改善目击者在摊牌中的辨认能力，减少目击者证据导致错误定罪无辜的可能性。

In the area of eyewitness identification, few studies compare showups (one-person identifications), simultaneous lineups (all lineup members viewed simultaneously), and sequential lineups (lineup members viewed one at a time) to determine which is most accurate. The current research involves a series of experiments in which participants will first watch a staged video of multiple perpetrators breaking into a storage unit and then complete a showup, sequential lineup, and simultaneous lineup, each involving a different suspect. Finally, participants will indicate their confidence in their decision and complete additional questions about the manipulation and witnessing experience. The current research has three objectives: to compare identification accuracy between showups and lineups within a single set of studies; to develop techniques that improve eyewitness identification; and to promote a better understanding of the underlying memory and decision-making processes that occur in showup and lineup identifications using formal computational models. The research focuses on improving eyewitness identification in showups and reducing the fallibility of eyewitness evidence leading to the wrongful conviction of the innocent.
