在美国和英国，每年都有数千名警察嫌疑人被目击者指认。不幸的是，这些嫌疑人中有许多是无辜的，这一点在他们往往在被监禁多年之后通过DNA测试被证明无罪时变得显而易见。因此，必须使用最能使目击者区分无辜嫌疑人和有罪嫌疑人的身份查验程序。虽然这两个国家的警察调查人员经常执行列队指认程序，但列队指认的细节却大不相同，因此还需要进行重要的直接比较。我们研究了这两种排队程序在（i）可辨别性（使用接收器操作特征分析）和（ii）可靠性（使用置信度-准确性特征分析）方面是否不同。共有2249名参与者观看了犯罪视频，随后使用6人同时照片排队程序（美国）或9人顺序视频排队程序（英国）进行测试。美国排队程序产生了显着更高的可辨别性和显着更高的可靠性。结果并没有指出两种手术之间观察到的差异的原因，但它们确实表明英国的阵容有很大的改进空间。
In the USA and the UK, many thousands of police suspects are identified by eyewitnesses every year. Unfortunately, many of those suspects are innocent, which becomes evident when they are exonerated by DNA testing, often after having been imprisoned for years. It is, therefore, imperative to use identification procedures that best enable eyewitnesses to discriminate innocent from guilty suspects. Although police investigators in both countries often administer line-up procedures, the details of how line-ups are presented are quite different and an important direct comparison has yet to be conducted. We investigated whether these two line-up procedures differ in terms of (i) discriminability (using receiver operating characteristic analysis) and (ii) reliability (using confidence–accuracy characteristic analysis). A total of 2249 participants watched a video of a crime and were later tested using either a six-person simultaneous photo line-up procedure (USA) or a nine-person sequential video line-up procedure (UK). US line-up procedure yielded significantly higher discriminability and significantly higher reliability. The results do not pinpoint the reason for the observed difference between the two procedures, but they do suggest that there is much room for improvement with the UK line-up.
