【摘要】 利用微计算机人机对话方式；以7项认知心理学测验对参加北京大学老年活动室文化活动的59名离退休人员进行了检测。结果表明，受试人员有着低于一般人的认知功能衰老速度，其液态智能年龄平均63．56±5．77岁，与实际年龄相比年轻0.75岁（P＜0．05）；认知速度相对老化度为1．24±0．36，与相同文化水平的知识型人群相比，平均降低0．15±0．36（P＜0.01）．由方差分析推论，参与不同文化活动均能减速缓认知功能的衰退．北京大学的经验提示，开展积极的社区老年文化活动能够帮助或诱导老年人树立良好的个人生活方式，保持愉悦的心理状态及和谐的人际关系，因而减少患染疾病的机会．延缓衰老的进程．更多还原

【Abstract】 59 retired senior citizcus took part in the recreational activities were studied by the method of the man-computer interaction for the maintenance of cognitive Performances.The results revealed that the aging speeds of congitive functions were slower. Their nuid intelligentialage was 63. 56±5. 77 and 0. 75 year-old younger than their actual age(P＜0. 05). The relative aging rate ofcognitive speed was 1. 24±0. 36, comparing with the same educational background person,the decrementwas 0. 15±0. 36(P＜0.01 ). According to the analysis of variance,after attending different recreational ac-tivities the slowing down of functions cognition after aging can be alleviated.更多还原
