OBJECTIVE Three studies examined the influence of a witness's identification speed on the identification decision of another witness. HYPOTHESES Based on research documenting cowitness effects we expected cowitness speed to affect identification decisions from target-absent photospreads. Without prior research testing the effects of cowitness speed, we did not have a specific prediction regarding how fast (vs. slow) cowitness identification decisions would affect participant-witnesses' identification rates in Study 1. Based on the results from Study 1, in Study 2 we predicted that fast (vs. slow) cowitness decisions would increase choices from target-absent photospreads when the cowitness was known to have made a positive identification. In Study 3, cowitnesses rejected the photospread. Based on the previous studies, we hypothesized that fast (vs. slow) cowitness decisions would decrease choices from target-absent photospreads. However, because a photospread rejection is qualitatively different from an identification, this prediction was tentative. METHOD In all three studies, participants watched one of 2 stimulus videos with a confederate cowitness. After the video, the confederate made a fast (10 s) or slow (4 min) identification. Participants then attempted an identification from a target-absent photospread. In Study 1 (N = 101), the confederate's decision from the photospread was ambiguous. In Study 2 (N = 200) the confederate announced making a positive identification. In Study 3 (N = 151) the confederate cowitness rejected the photospread. RESULTS In all 3 studies, participants paired with a fast cowitness made more choices from the target-absent photospread than did participants paired with a slow cowitness. CONCLUSIONS Fast cowitness identifications increased choices from the target-absent photospread regardless of whether a cowitness's decision was ambiguous (Study 1), whether they made an identification (Study 2), or rejected the photospread (Study 3). Given the effects of cowitness speed on identification decisions, it might be advisable to standardize the duration of identification procedures and inform witnesses of this standardization.

Cowitness的识别速度会影响目标缺失的光罩的选择。

目的三项研究检查了证人的识别速度对另一名证人的识别决定的影响。假设根据研究记录牛cow效应的研究，我们预计牛it速度会影响无目标光罩的识别决定。如果没有先前的研究来测试牛仔布速度的影响，我们就无法确定在研究1中（相对于慢速）牛仔布识别决策将如何影响参与者/证人的识别率的具体预测。基于研究1中的研究结果2我们预测，快速（相对于慢速）的决定将在已知靶点为阳性的情况下增加对目标缺失光罩的选择。在研究3中，牛仔拒绝了光差。根据以前的研究，我们假设快速（相对于慢速）决策可以减少没有目标的光罩的选择。但是，由于光覆盖拒绝与定性在质量上有所不同，因此该预测是暂定的。方法在所有三项研究中，参与者都观看了2个刺激性视频，其中一个具有同盟情结。录完视频后，同盟进行了快速（10 s）或慢速（4 min）识别。然后，参与者尝试从没有目标的光罩中进行识别。在研究1（N = 101）中，同盟国从光掩膜中做出的决定含糊不清。在研究2（N = 200）中，同盟宣布做出肯定的身份。在研究3中（N = 151），同盟的反叛拒绝了光差。结果在所有3项研究中，与快慢配比的参与者相比，快配气的参与者从目标缺失的光罩中做出了更多选择。结论快速的cow鉴别可以从目标缺失的光photos中增加选择，而不管cow的决定是否模棱两可（研究1），是否做出识别（研究2）或拒绝光read（研究3）。考虑到考核速度对识别决定的影响，建议对识别程序的持续时间进行标准化，并告知证人该标准化过程。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。他们的决定是模棱两可的（研究1），是确定身份（研究2），还是拒绝照片覆盖（研究3）。考虑到考核速度对识别决定的影响，建议对识别程序的持续时间进行标准化，并告知证人该标准化过程。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。他们的决定是模棱两可的（研究1），是确定身份（研究2），还是拒绝照片覆盖（研究3）。考虑到考核速度对识别决定的影响，建议对识别程序的持续时间进行标准化，并告知证人该标准化过程。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
