    摘要: 研究的目的是根據信號偵測理論設計一套營造業的工地危害情境測驗,探討安全衛生科系應屆畢業生之危害風險知覺與判斷。
    The purpose of this study was to develop an instrument using Signal Detection Theory (SDT) to measure hazard risk perceptions of people in construction site. Four tests (Safety Attitude, Hazard Risk Cognition, Safety Knowledge, and Construction Site Hazard Risk Perception) were designed in this study.
      Two-way ANOVA showed that the factors of the gender, age, and years of working did not affect the hazard risk perceptions when the subjects observed the unsafe pictures of the construction site. Six types of major injuries in construction sites were categories in different risk perception levels. The types of injuries in “collapse”, “falls”, “fallen objects” , and “stab, cut, abrasion” were categories in first hazard risk perception level; the second hazard risk perception level was “fires and explosions”, the lowest level was “electric shocks”.
      The results of the measure in signal detection, the sensitivity value(d’)of the male and female were 1.28 and 1.15. Two-way ANOVA of the sensitivity value(d’) showed significant interaction between gender and working years. The measure of the signal detection threshold(β)of the male and female were 0.44 and 0.53, meaning both were categories in “non-conservative”.
