A battery of cognitive tests designed to measure the constructs of episodic memory, perceptual speed, fluid ability, executive functioning, and vocabulary was administered to 330 adults between the ages of 18 and 89. Each participant also performed 4 different tasks designed to assess source memory. Structural equation modeling was used to evaluate the validity of a source-memory construct and to explore the relation of the source-memory construct to age and to the other cognitive variables. The variance common to the source-memory variables was strongly related to other cognitive abilities, suggesting that source memory may not have discriminant validity, and there were only small unique age-related effects on the source-memory construct after the influence of other abilities was considered.
对330名年龄在18岁至89岁之间的成年人进行了一系列认知测试，这些测试旨在测量情景记忆、知觉速度、流体能力、执行功能和词汇等结构。每位参与者还执行了4项不同的任务，旨在评估源记忆。采用结构方程模型来评估源记忆结构的有效性，并探讨源记忆结构与年龄以及其他认知变量之间的关系。源记忆变量的共同方差与其他认知能力密切相关，这表明源记忆可能没有区分效度，并且在考虑其他能力的影响后，源记忆结构上与年龄相关的独特效应很小。
