A multinomial model for lineups – request for extension

项目第一阶段的目的是验证新开发的多项排队模型（从现在开始：2 HT-EIM用于两个高阈值目击者识别模型）。2 HT-EIM包含四个参数，这些参数是基于对阵容的判断进行估计的：- 一个参数用于检测犯罪者在队列中的存在（dP），一个参数用于检测犯罪者的不存在（dA），在不公平的队列中选择“显眼”的肇事者或被错误怀疑的人的一个参数（B用于有偏选择）和一个参数用于基于猜测过程的选择（g用于基于猜测的选择）。到目前为止，已经进行并发表了项目提案中的四个在线验证实验（Winter，Menne，Bell & Buchner，2022）。此外，为了验证目的，对8个已发表的数据集进行了重新分析，并发表了分析结果（Menne，Winter，Bell & Buchner，2022 b）。此外，还进行了四次在线实验，使用项目提案中建议的变形操作来生成不公平的阵容。记录这四个实验的手稿已经提交出版（Menne，Winter，Bell & Buchner，2022 a）。在项目的第一阶段成功验证2 HT-EIM之后（Menne等人，2022 b; Winter等人，2022），该模型现在将被用来回答新的科学问题，目前还不清楚是什么过程的基础上可观察到的行为的影响。具体而言，这一奋进有四个目标。第一个目标是要回答的问题，如何上下文还原与多个嫌疑人在阵容影响的检测和猜测过程中可观察到的判断。第二个目标是回答练习阵容如何影响检测和猜测过程的问题。第三个目标是回答刺激记忆相关的元认知如何影响检测和猜测过程的问题。最后，第四个目标是回答嫌疑人在列队中的位置对检测和猜测过程有什么影响的问题。计划为这四个目标中的每一个进行两次实验。

The aim of the first project phase was to validate the newly developed multinomial model for lineups (from now on: 2HT-EIM for two-high threshold eyewitness identification model). The 2HT-EIM contains four parameters that are estimated on the basis of judgments in lineups: one parameter for the detection of the presence of the perpetrator (dP) in the lineup and one for the detection of the absence of the perpetrator (dA), one parameter for the selection of ‘conspicuous’ perpetrators or wrongly suspected persons in unfair lineups (b for biased selection) and one parameter for choices based on guessing processes (g for guessing-based selection). To date, four online validation experiments from the project proposal have been conducted and published (Winter, Menne, Bell & Buchner, 2022). Also, eight published datasets have been reanalyzed for validation purposes and the analyses have been published (Menne, Winter, Bell & Buchner, 2022b). In addition, four more online experiments have been conducted using the morphing manipulation suggested in the project proposal to generate unfair lineups. The manuscript documenting these four experiments has been submitted for publication (Menne, Winter, Bell & Buchner, 2022a).Following the successful validation of the 2HT-EIM in the first phase of the project (Menne et al., 2022b; Winter et al., 2022), the model shall now be used to answer new scientific questions for which it is so far unclear what processes underlie the effects on observable behavior. Specifically, there are four goals for this endeavor. The first goal is to answer the question of how context reinstatement with multiple suspects in lineups affects the detection and guessing processes underlying observable judgments. The second goal is to answer the question of how practice lineups affect the detection and guessing processes. The third goal is to answer the question of how stimulating memory-related metacognitions affects detection and guessing processes. Finally, the fourth goal is to answer the question of what effects the position of a suspect in a lineup has on detection and guessing processes. Two experiments are planned for each of these four goals.
