最近的研究使用校准方法表明，目击者的信心评估后立即获得一个积极的识别决定提供了一个有用的指导，可能的准确性识别。本研究通过改变编码和识别测验之间的保持间隔，扩展了对置信度-准确度关系边界条件的研究。参与者（N = 1，063）在社区环境中查看五个不同目标中的一个，并立即或几周后尝试从8人目标存在或不存在的阵容中进行识别。与即时条件相比，延迟条件产生更大的过度自信和更低的诊断性。然而，对于选择者在这两个保留时间间隔有一个有意义的CA关系和诊断是强得多，在高比低的置信水平。
Recent research using a calibration approach indicates that eyewitness confidence assessments obtained immediately after a positive identification decision provide a useful guide as to the likely accuracy of the identification. This study extended research on the boundary conditions of the confidence-accuracy (CA) relationship by varying the retention interval between encoding and identification test. Participants (N = 1,063) viewed one of five different targets in a community setting and attempted an identification from an 8-person target-present or -absent lineup either immediately or several weeks later. Compared to the immediate condition, the delay condition produced greater overconfidence and lower diagnosticity. However, for choosers at both retention intervals there was a meaningful CA relationship and diagnosticity was much stronger at high than low confidence levels.
