对129和233名年龄从20岁到79岁的成年人进行的两组测试的数据进行了分析，以探索模型的可行性，假设处理资源的数量或效率的年龄差异是认知功能中观察到的许多年龄差异的原因。路径分析程序用于估计年龄对认知表现的直接和间接或资源介导的影响。结果表明，以简单的速度和记忆测量作为加工资源的指标，强资源模型的支持很少，而从弱资源模型中获得的证据表明，相对于不受加工资源介导的资源，资源介导的年龄差异贡献较小。
Data from two batteries of tests administered to 129 and 233 adults, ranging from 20 to 79 years of age, were analyzed to explore the viability of models postulating that age differences in the quantity or efficiency of processing resources are responsible for many of the age differences observed in cognitive functioning. Path-analysis procedures were used to estimate the direct and indirect, or resource-mediated, effects of age on cognitive performance. Results, with simple speed and memory measures serving as the indexes of processing resources, indicated that there was little support for a strong resource model, and evidence derived from a weak resource model suggested that resourcemediated contributions to age differences are small, relative to those not mediated by processing resources.
