摘　　要：目的 研究执行长远航任务的舰员在不同阶段的认知水平变化规律,为以后长远航舰员选拔、制定认知功能损害防治或认知功能增强方案等提供科学指导依据,以减少军队长远航任务的事故发生率.方法对执行为长远航任务的185名舰员进行紧密跟踪研究,采用职业倦怠量表、连线测试（A、B）、持续操作测试软件（CPT）进行测试对比分析.结果 在为期3个月的长远航期间,舰员在航行35 d时的倦怠程度均大于航行前1周和航行后1周,差异均有统计学意义（P＜0.05）;连线测试A、B的完成时间均大于航行前1周和航行后1周的完成时间,差异均有统计学意义（P＜0.05）,CPT2、3、4位数的综合得分均低于航行前1周和航行后1周,差异均有统计学意义（P＜0.05）.结论 长远航影响舰员的信息处理速度、推理、注意力、警觉性等认知能力.Objective To study the change pattern of cognition of the ship crew at different stages during prolonged sea deployment,so as to provide scientific evidence for the screening of the ship crew,development of the protocols for the prevention,treatment and improvement of cognition impairment that occurred among the ship crew with a view to reduce the rate of accidents during prolonged deployment at sea.Methods A retrospective study was made on the 185 naval ship personnel who were involved in the 3-month prolonged sea deployment.Detection,comparison,and analysis were performed by using the occupational fatigue scale,the on-line test （A,B） and the continuous performance test （CPT）.Results During the 3-month prolonged sea deployment,the fatigue level of the ship crew at day 35 was significantly greater than the fatigue level one week before and after the prolonged deployment,and statistical significance could be seen,when comparisons were made between them （P 〈 0.05）.The length of time spent on the on-line test A and B was longer than that one week before and after the prolonged deployment,and statistical significance could also be seen,when comparisons were made between them （P 〈 0.05）.The accumulated scores of the continuous performance test were all lower than those one week before and after the prolonged deployment,and statistical significance was also noticed,when comparisons were made between them （P 〈 0.05）.Conclusions Prolonged sea deployment could affect such cognitive capabilities as information processing,reasoning,attention and alert of the ship crew.
