摘要： 该工作应用人机对话方式完成心算、符号数字、数字鉴别和计数四项作业认知速度年老减慢及学习改善过程的研究，被试３５０人，４６—７５岁。研究结果表明：四项认知作业速度随年老进行性减慢；然而，老年人经学习训练认知作业速度可明显改善。上述变化程度与作业所需时间有密切关系，提示年老过程中枢信息加工过程速度的减慢快于外周感觉─运动过程速度的减慢，学习改善作用也可能主要是中枢过程速度的提高。

Abstract: A study on age-related cognitive speed slowing and the learning-improving processes was accomplished by using the method of man-computer interaction in arithmetic, symbol-digit, digit discrimination and count tasks. The subjects were 350 volunteers of 46 to 75 years of age. The results indicated that the cognitive speed of all the tasks showed progressively with increased age, however, the cognitive speed could be improved obviously through learning-training in the old aged. The above degrees in change were closely related to the requisite times for the tasks, Thus, it suggested that central cognitive processes slowed more with advancing age than peripheral sensorimotor processes, the learning-improving role could be major in the enhancing on the speed of central processes.

Key words: aging, cognitive speed slowing, learning-improving ability
