生产力要求、时间压力和认知要求高的施工任务增加了工人的觉醒和压力；然而，目前尚不清楚这些因素是如何使风险补偿效果恶化并导致意外危害的。本文考察了有限的时间和增加的心理负荷在多大程度上放大了工人的风险补偿行为。本文利用沉浸式混合现实环境模拟电构建任务，应用一种有前途的神经成像方法（功能性近红外光谱- fNIRS）研究了正常和应激条件下个体认知反应和决策动力学的变化。结果表明，由于认知资源有限，员工无法处理周围信息，在时间压力和心理需求增加的情况下，员工对潜在风险有错误的认知。这些认知失败导致了对安全保护和风险决策的过度依赖，并降低了安全性能。本文对建筑行业风险承担和风险补偿行为的潜在神经机制以及消除风险补偿偏见的重要性提供了有价值的见解。
Productivity demands, time pressure, and cognitively demanding construction tasks increase workers' arousal and stress; however, it is not clear how these factors may worsen risk compensation effects and lead to unanticipated hazards. This paper examined the extent to which limited time and increased mental load amplify the risk compensatory behavior of workers. Using an immersive mixed-reality environment to simulate an electrical construction task, this paper applied a promising neuroimaging approach (functional near-infrared spectroscopy- fNIRS) to study changes in individuals' cognitive responses and decision dynamics under normal and stressful conditions. The results showed that workers failed to process surrounding information due to limited cognitive resources, and misperceived potential risks under time pressure and increased mental demand. These cognitive failures then led to increased overreliance on safety protections and at-risk decisions, and decreased safety performance. This paper offers valuable insights into the potential neural mechanism driving risk-taking and risk compensatory behaviors and the importance of counteracting risk compensation bias in the construction industry.
