为探索成人认知功能的发展与认知老化轨迹，基于中华成人智力量表常模样本数据，统计控制教育水平和职业构成以部分消除同辈效应，考察智商和智力指数的年龄趋势。结果晶体智力指数（CI）在25～44岁间增加0．69分后缓慢递减，高低差值3．3分；注意记忆指数（AMI）在25～44岁间共减少3．3分，45岁后各组均数以3分左右的速度递减。流体智力指数（FI）和智商的年龄差异模式与AMI类似，幅度缩减。提示中国成人晶体智力在74岁前比较稳定，没有明显老化，流体智力和注意记忆能力可能在45岁开始明显线性老化。

To explore the development of cognitive functioning and aging of Chinese aduhs, the data of the standardization sample of the Intelligence Scale for Chinese Adults were adopted to estimate special mean of intelligence quotient and three intelligence indices for every age-group, during which education level and occupation were controlled statistically in order to diminish cohort effects. Different fashion in age trend was found among the three indices and IQ. Crystallized intelligence index increased 0.69 from age -group 25-29 to age-group 35-44 and then decreased 3.3 totally. Attention-memory index peaked in the age-group 25-29 and decreased 3.3 from age- group 25-29 to 34-44 totally, while decreased 3 or so in every group from age-group 45-54 to 70-74. The fluid intelligence index and IQ shared resembling fashion of age trend with the crystallized intelligence index, albeit the range between the highest score and the lowest score was shorter. The results suggest that crystallized intelligence maintain stable before 74 years old while in domain of fluid intelligence and ability of attention and memory obvious linear decline present in Chinese adults.
