| 摘 要： | 研究加工速度和工作记忆在认知能力年老化过程中的作用。被试为20-90岁的健康成人1350名，完成加工速度、工作记忆及一组认知能力测验，应用分层回归分析方法考查在年老化过程中加工速度和工作记忆对多项认知变量的作用量。结果表明，在年老化过程中，加工速度和工作记忆对认知变量的作用量分别约为87% 和76%；二者的综合作用量约为94%。说明加工速度和工作记忆在认知能力年老化过程中起决定作用

| Abstract: | This study, involving a sample of 1350 adults of 20 to 90 years of age and a battery tests of sensory-motor speed, working memory, normal memory, thought and spatial representation in computer, was conducted to analyze the roles of processing speed and recognition in cognitive aging by using the method of hierarchical regression analysis. The results indicated: (1) The contributions of processing speed and working memory to cognitive abilities in aging were about 87% and 76%. (2) The total contribution of processing speed and working memory to cognitive abilities in aging was about 94%. These results led us to conclude that processing speed and working memory play determinative roles in cognitive aging. |
