Based on the rescuers' distinctive psychological reaction in different phases of the rescue operation, we aims to propose measures for administration of the team in order to better fulfill the rescue duties and provide references for future medical service in non-war operations such as an earthquake relief.展开更多

Methodology: 14 subjects were as- signed randomly into groups consisting of 2 members. Both the members from each group performed both the visual and auditory tests. The tests were taken from the DirectRT software program from a laptop. The DirectRT software consists of Testlabvisual and Testlabsounds to test the reaction times to visual and auditory stimuli. The 2 members from each group completed both the visual and auditory reaction times, the data was taken and the mean reaction time was calculated excluding the first and last values. Results: The results show that the mean visual reaction time is around 331 milliseconds as compared to the mean auditory reaction time of around 284 milliseconds. Conclusion: This shows that the auditory reaction time is faster than the visual reaction time. And also males have faster reaction times when compared to females for both auditory as well as visual stimuli.展开更多

Strong emotional and psychological reaction caused by traumatic factors will form psychological shadows, and the improper coping of these events will lead to a post-traumatic stress disorder. In this paper, the author makes an exploration on the roots of psychological trauma and of post-traumatic stress reaction or disorders, which were caused by natural traumatic event, such as floods, snowstorms, earthquakes and other man-made factors such as wars, accidents from a psychological point of view. Finally, some suggestions of intervention are provided for the relevant departments to make relevant rebuilding policies.展开更多
