为提高建筑工人的危险认知水平,以认知心理学为基础,运用心理测量范式获取工人对不同事故的危险认知结果,用分类对比法探究认知结果的差异规律,分析工人的危险认知结果特点、危险敏感性变化规律、危险认知偏差成因等深层问题。研究表明:危险认知结果与危险特征对工人的刺激程度和工人对该刺激的敏感程度密切相关,具有模糊性、差异性和变化性;相同条件下,工人对低危、频发、险兆特征直观、可控性好的事故的危险认知差异较大,这种危险易被低估;工人中会出现适应危险的现象,造成危险敏感性下降和危险感知麻木;而造成工人危险认知偏差的主要原因是危险敏感性下降、危险认知主观性过强和高估自身应对危险的能力。
In order to improve the cognitive level of danger for construction workers, cognitive psychology is used as a basis to obtain the cognitive results of workers’ perceptions of different accidents based on psychological measurement paradigms. The categorization contrast method is used to explore the differences of cognition results and to analyze the danger identification of workers Knowledge of the characteristics of the outcome, changes in the sensitivity of dangerous sensitivities, and other deep-seated problems in the causes of dangerous cognitive bias. The results show that: the risk cognition and risk characteristics are closely related to workers ’sensitivity to workers’ sensitivity to the stimuli, and are ambiguous, different and changeable; under the same conditions, Intuitive, controllable accidents have a wide range of cognitive differences, which are easily underestimated; workers adapt to the danger of becoming less susceptible to dangerous sensitivities and nuisance perceptions; and workers are at risk of cognitive bias The main reason is the decrease of risk sensitivity, the subjectivity of risk perception and the overestimation of their ability to deal with danger.
