认知过程被发现在导致建筑事故的人为错误中起着重要作用。更好地理解与构建相关的认知过程将阐明人类易犯错误的更可预测的种类，并允许创建避免上述错误的策略。到目前为止，还没有发表的研究对工作记忆和导致建筑事故的人为错误之间的关系进行过实证研究。为了解决这一差距，本研究使用眼动测量来检查工作记忆负荷如何影响工人的注意力分配和对建筑中潜在危险的检测。为了确定记忆负荷的变化是否会影响扫描模式和对危险的认识，19名学生被招募参加了一项操纵工作记忆负荷的眼球跟踪实验。结果表明，随着工作记忆负荷的增加，参与者识别危险的能力降低。此外，研究结果还表明，不同工作记忆负荷下的视觉搜索策略存在显著差异。这项研究提供了一个概念证据，即眼球运动可以作为建筑工人在寻找危险时工作记忆负荷变化的指标，而不会对受试者进行任何积极干预。
Cognitive processes have been found to play a significant role in contributing to the human errors that lead to construction accidents. A better understanding of cognitive processes as they relate to construction will elucidate the more predictable varieties of human fallibility and allow for the creation of strategies to avoid said errors. To date, no published study has empirically investigated the relationship between working memory and the human errors that lead to accidents in construction. To address this gap, this study uses eye-movement metrics to examine how working-memory load impacts worker’s attentional allocation and the detection of potential hazards in construction. To determine whether changes in memory load influence scan patterns and awareness of hazards, 19 students were recruited to participate in an eye-tracking experiment in which working memory load was manipulated. The results demonstrated that as working memory load increases, the ability of participants to identify hazards decreases. In addition, the results demonstrate that there is a significant difference between the visual search strategies of people under different working-memory loads. This study provides a proof of concept that eye movements can be used as an indicator of variation in working-memory load among construction workers while they search for a hazard without any active interference with the subject.
