Advocates claim that the sequential lineup is an improvement over simultaneous lineup procedures, but no formal (quantitatively specified) explanation exists for why it is better. The computational model WITNESS (Clark, Appl Cogn Psychol 17:629-654, 2003) was used to develop theoretical explanations for the sequential lineup advantage. In its current form, WITNESS produced a sequential advantage only by pairing conservative sequential choosing with liberal simultaneous choosing. However, this combination failed to approximate four extant experiments that exhibited large sequential advantages. Two of these experiments became the focus of our efforts because the data were uncontaminated by likely suspect position effects. Decision-based and memory-based modifications to WITNESS approximated the data and produced a sequential advantage. The next step is to evaluate the proposed explanations and modify public policy recommendations accordingly.
支持者声称，顺序排列比同时排列程序有所改进，但没有正式（定量规定）的解释说明为什么它更好。计算模型 WITNESS（Clark，Appl Cogn Psychol 17：629-654，2003）被用于为顺序排列优势提供理论解释。在其当前形式中，WITNESS 仅通过将保守的顺序选择与自由的同时选择配对产生了顺序优势。然而，这种组合未能近似四个表现出较大顺序优势的现有实验。其中两个实验成为我们努力的焦点，因为这些数据不受可能的嫌疑人位置效应的影响。基于决策和基于记忆的 WITNESS 修改近似了数据并产生了顺序优势。下一步是评估提出的解释并相应地修改公共政策建议。
