| Summary: | 碩士 === 中國科技大學 === 土木與防災設計系 === 103 === In this study, the method for easing the situation on construction workers of inattentional blindness due to over-concentration on work will be discussed. To start with, related papers were collected and summarized so to thoroughly understand the circumstances that may lead to the induction of inattentional blindness, and also the easing methods for such situation. At the same time, questionnaires and videos were produced based on the template designed by Chia-Wen Liao , Jane Cheng Yu (2014) for this study. The study includes two experiments. After completion of two experiments, the results were compared with those from the experiment conducted by Chia-Wen Liao (2014), so to investigate the effectiveness of the methods, and determine which method is more effective. In the experiment, the participants were first informed about the matters need attention. After that, participants watched the mock video of construction site, followed by filling in the questionnaires. The study targeted students from The China University of Technology. 71 questionnaires were distributed, 100% of the questionnaires were collected and 100% of the questionnaires were valid. Based on the collected questionnaires, analysis on credibility, Chi-square test were carried out and descriptive statistics were studied.After series of experiments and analysis, the results could be concluded as below: Different methods for easing the situation of inattentional blindness were used in the two experiments (light-reflecting line and warning sign). However, from the experimental result, light-reflecting line did not show expected effect in easing the situation of inattentional blindness. On the other hand, warning sign could reduce the happening of inattentional blindness. The result shows that warning sign is more effective than light-reflecting line in easing the situation of inattentional blindness.
