摘　　要：应用二维年龄多作业回归分析方法，研究了７３４名４６～７５岁的脑力劳动者文化水平对老年认知作业速度衰减的影响。结果表明：高、低文化两组四项认知作业速度均随增龄成比例递减，但低文化组较高文化组递减迅速；两文化组认知作业速度年老衰减过程的差异表现为：低文化组在６０岁之前衰减迅速，而高文化组在６０岁后衰减才开始加速；认知作业速度的年老衰减不是同步的，其老化度的分离程度与增龄成正比，与文化水平成反比关系。The effects of educational level on speeds of cognitive tasks in aging were studied in 734 rolunteess of 46 ～75 years of age by using the multitask regressive analyses of two-dimensional ages. The results indicated :(1) the speeds of the four tasks slowed down proportionally with age in both groups of the higher and the lower educational level, but the speeds slowed with age were more significant in the lower educational level as compared with the group of the higher educational level. (2) It was different for the progresses of speeds slowing with age in both groups. The speeds slowed down more quickly before 60 years old in the group of the lower educational level, and the speeds slowing did not accelerate until 60 years old in the group of the higher educational level. (3) The speeds slowing of cognitive tasks did not progress synchronously in aging.The scattered extent of the speeds slowing of cognitive tasks revealed positive proportion to age and negative proportion to educational level.
