| 摘 要： | 应用两维年龄多作业回归分析方法，研究了四项非词语性认知作业速度年老衰减规律的数学描述形式。被试共７３４名，４６─７５岁。结果表明：五个年老组与４６─５０岁组作业时间之间呈线性函数关系，其线性方程的斜率值随年老组的增龄而增大。

| Abstract: | 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. |
