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

在目击者辨认领域，很少有研究比较展示（一人辨认）、同时列队（所有列队成员同时观看）和连续列队（列队成员一次观看一个）来确定哪个最准确。目前的研究包括一系列实验，在这些实验中，参与者首先观看一段多名肇事者闯入一个存储单元的阶段性视频，然后完成一个展示、连续指认和同时指认，每个指认都涉及一名不同的嫌疑人。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经验的附加问题。目前的研究有三个目标：在一组研究中比较显示组和排列组之间的识别准确性；开发提高目击者识别能力的技术；并通过使用正式的计算模型来促进对出现和阵容识别中发生的潜在记忆和决策过程的更好理解。本研究的重点是提高出庭证人的识别能力，减少目击证人证据的不可靠性，从而导致对无辜的错误定罪。

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.
