摘　　要：本工作应用自行设计的计算机逐级限速程序,研究了年老过程四项认知作业完成量与作业速度的相互关系。被试350人,46—75岁。研究结果表明:1、随着计算机所限时间的缩短,各项作业完成量均随年老下降迅速,作业完成量对于作业速度的依存关系随年老表现极为明显;2、在逐级限速条件下,四项认知作业完成量的年老敏感性顺序与作业速度的年老敏感性顺序基本相同,即是:符号数字、心算、计数和数字鉴别。With the method of gradually limiting speed by using a computer, we studied the relationship between quantity and speed of four cognitive tasksin aging. The subjects were 350 healthy volunteers of 46 to 75 years ofage. The results indicated: 1.The shorter the performance time limited bythe computer, the less the quantity accomplished in the four tasks withincreased age. 2. The order in sensitivity of the performance quantity acco-mplished in conditions of speeds limited to age was symbol-digit, arithmetic,count and digit discrimination, which was consistent with the order insensitivity of the performance speed to age.
