Effect of Experience-based Safety Education on Human Errors Triggered by Urgency

Abstract

This study tested the effects of the experience-based safety education on human errors triggered by urgency. Of 81 participants, 40 were assigned to the education group that participated in a task related to experience-based safety education. The others were assigned to the control group that participated in a task unrelated to human errors triggered by urgency. Participants in the education group exhibited a reduction in task performance in the urgency condition, in which a time limit was set for the completion of the task. Attitude and behaviour triggered by urgency were assessed by using a questionnaire before (Time 1), shortly after (Time 2) and a month after education (Time 3). The results showed that while the control group did not exhibit any changes in their attitude and behaviour, the education group’s attitude changed in the safe direction from Time 1 to Time 2, and that this tendency persisted in Time 3. The utility and limitation of the educational intervention conducted in this study were discussed based on the findings of this study.
