摘　　要：近年来一般流体智力的认知结构与老化机制已成为认知研究中的一个热点。本研究通过结构方程模型探讨了认知加工速度、工作记忆、注意能力与一般流体智力的联系,结果表明:加工速度、控制性注意是一般流体智力的主要认知成分,工作记忆并非一般流体智力的认知成分,两者之间是共变关系。加入年龄因子的结构方程模型也证实了加工速度和控制性注意是一般流体智力老化的重要中介因子。The cognitive structure and the aging mechanism of general fluid intelligence ha ve caught many research interests in recent years. Present study discus ses these proble ms from a cross-the-board point, with a structure modeling approach. Taking pr oc essing speed, working memory and attention ability as latent variables, processi ng speed and selective attention were proved to be the main cognitive components of general fluid intelligence, but working memory was excluded. The structure mode l of aging mechanism also proved that processing speed and selective attention a re the most important media between age and general fluid intelligence.
