摘要
目的探讨年龄因素对飞行员基本认知能力的影响程度。方法将499名来院体检飞行员按年龄分为三组:1组(117例),年龄22~25岁;2组(286例),年龄26~30岁;3组(95)例,年龄31~40岁。分别采用《基本认知能力测验》系统2.0版。结果不同年龄组中数字拷贝随着年龄的增长,呈减退趋势,三组比较具有统计学差异(F=5.61,P<0.05);总分得分成绩3组显示了明显的优势,其次是1组。三组比较具有统计学差异(F=3.82,P<0.05);三组间均数比较,项目数字拷贝组间比较有统计学差异,随着年龄增长有明显的减退趋势(P<0.01);相反心算能力组间比较随着年龄增长有明显的提升趋势,有统计学差异(P<0.05);汉字比较、汉字旋转、双字词再认、无意义图形再认组间比较没有统计学差异(P>0.05);数字广度1组与2、3组比较有统计学差异,3组成绩占有明显优势(P<0.05),总分成绩1组与2、3组比较有统计学差异(P<0.05),而2组与3组比较无统计学差异(P>0.05)。结论年龄在22~40岁范围内,飞行员除项目数字拷贝随着年龄增长呈减退趋势外,综合总分成绩31~40岁组段的认知能力有明显的优势。
Objective To analyze the impact degree of age factor to pilots' basic cognitive ability.Methods Four hundred and ninety nine pilots were divided into three groups according to the ages: Group I(117 cases),aged 22 to 25 years;Group Ⅱ(286 cases),aged 26 to 30 years;Group Ⅲ(95 cases),aged 31 to 40 years.The detection used basic cognitive ability test system2.0.Results Digital copy of different age groups shows downward trend with the age increasing,which reveals significant difference(F=5.61,P0.05).Total scores of Group Ⅲ are significantly higher than any other age groups and of Group Ⅰ are the next,which reveals significant difference(F=3.82,P0.05).To the averages comparing of different age groups,the item digital copy shows significant difference and the score appears downward trend with the age increasing(P0.01).Mental arithmetic ability shows upward trend with the age increasing and the difference is significant,too(P0.05).Item character comparing,character rotation,double-word recognition,meaningless graphic recognition do not show any of statistic difference(P0.05).To the figure extent,there are both significant difference between Group Ⅰ and Group III,Group II and Group Ⅲ,and score of Group Ⅲ is obviously higher than other groups'(P0.05).To the total score,between Group Ⅰ and Group Ⅱ,Group Ⅱ and Group Ⅲ are both significantly difference(P0.05).Between Group Ⅱ and Group Ⅲ is without it(P0.05).Conclusion As the age is in 22-40,pilots' composite total score of cognitive ability in 31 to 40 years group are obvious higher than other groups,except for the item digital copy will decrease with the age increasing.
