安全检查站用于将具有潜在危险的物品和个人挡在安全区域之外。虽然技术进步可以通过准确性和速度来提高安全效率，但最终的成功或失败在很大程度上取决于人类的表现。因此，有必要尽量减少源于人类认知能力限制的任何缺点。认知表现可能受到许多因素的影响，包括搜索任务所施加的因素（例如，禁止项目的数量）和搜索者自身的基本能力（例如，能力和经验）。在这里，我们回顾并讨论了任务本身的四个具体挑战，这些挑战可能会对安全筛选的准确性产生负面影响：目标可见性，未知的目标集，可能存在多个目标，以及目标流行率低。对于每一个，我们提出了面临的挑战和挑战的潜在意义，然后提供可能的解决方案的基础上，现有的文献。版权所有（c）2014约翰威利父子有限公司
Security checkpoints are used to keep potentially dangerous items and individuals out of secure areas. Although technological advances can enhance security efficacy through both accuracy and speed, ultimate success or failure is largely determined by human performance. As such, it is necessary to minimize any shortcomings that stem from the limits of human cognitive abilities. Cognitive performance can be influenced by numerous factors, including those imposed by the search task (e.g., the number of prohibited items) and the basic abilities of the searchers themselves (e.g., competency and experience). Here, we review and discuss four specific challenges of the task itself that can negatively affect the accuracy of a security screening: target visibility, an unknown target set, the possible presence of multiple targets, and low target prevalence. For each, we present the challenge faced and the potential significance of the challenge and then offer possible solutions on the basis of the existing literature.
