- 安全训练一直被认为是一个有前途的方法，以提高工人的危险识别技能在建筑地盘。为了提高安全培训的有效性，对培训环境、个人学习能力和课程个性化等不同特征进行了研究。然而，由于记录显示，即使接受安全培训后，工人仍然错过了危险，了解未识别危险的基本认知原因成为制定有效的个性化安全培训的关键一步。本研究采用360°全景摄影法，对30名建筑工人的视觉搜索策略进行了实证研究，并对工人的危险识别技能进行了评估。结果表明，几个认知局限性造成的故障，在危险识别，包括注意失败，无意失明，和低感知风险。基于这些发现，本研究提出了一个个性化的安全培训框架，以解决这种认知的局限性，以提高在建筑业的职业安全。
– Safety training has long been considered a promising method to enhance workers’ hazard identification skills within construction sites. To improve the effectiveness of safety training, such varied features as a training environment, individuals’ learning ability, and lesson personalization have been investigated. However, as records show workers still miss hazards even after receiving safety training, understanding the fundamental cognitive reasons for unrecognized hazards becomes a crucial step toward developing effective personalized safety training. This study used various 360° panoramas of construction scenarios to empirically examine 30 workers’ visual search strategies and assess workers’ hazard identification skills. Results suggest several cognitive limitations caused failures in hazard recognition, including attentional failure, inattentional blindness, and low perceived risk. Based on these findings, this study proposes a personalized safety training framework to address such cognitive limitations to improve occupational safety in the construction industry.
