目的分析不同种类、不同年龄组特勤人员认知能力的差异。方法用专门的心理训练设备对特勤人员的各项认知能力进行训练。结果空勤人员的记忆长度、深度知觉、速度知觉明显高于海勤人员。≥41岁组的记忆长度、速度知觉明显低于其它两个年龄组,≤30岁组的简单反应时明显高于其它两组。结论前期的心理筛选和后期的训练是造成海勤与空勤人员认知能力差别的原因,年龄的增大会降低认知能力。 Objective To analyze the differences of cognitive abilities among different types and special teams of different age groups. Methods Use specialized psychological training equipment to train the special staffs’ cognitive abilities. Results aircrew memory length, depth perception, speed perception was significantly higher than the staff of the sea. The memory length and speed perception of the group of ≥41 years old were obviously lower than those of the other two age groups. The simple reaction time of ≤30 years old group was obviously higher than the other two groups. Conclusion Psychological screening and training at the early stage are the reasons for the differences in cognition between seafarers and flight attendants. Increasing age may reduce cognitive ability.
