非词语性认知作业速度年老衰减规律的数学描述

A study on the mathematical pattern of cognitive slowing in 4 nonlexical tasks with age was accomplished by using the multitask regressive analyses of two age dimensions in 734 subjects of 46 to 75 years of age.The results indicated there were linear functional relations between task time of the 5 groups of older adults and the group of 46-50 years of age,the slopes of the linear equations increased with advanced age of the group of older adults.
