本研究调查了加工速度和工作记忆在前瞻性和回顾性记忆中的作用（即，自由回忆）在老年时的表现。目的是研究65至80岁年龄范围内两个记忆领域的年龄相关差异。样本包括来自苏黎世认知老化纵向研究第1波数据的361名老年人。使用结构方程模型，前瞻记忆，自由回忆，工作记忆和加工速度被确定为潜在的结构。研究发现，前瞻记忆的年龄影响比自由回忆的年龄影响更大。此外，当控制工作记忆和处理速度的个体差异时，独特的年龄效应仍然存在于前瞻性记忆中，而不是回顾性记忆。结果表明，在老年，前瞻性记忆是一个独特的记忆结构，是部分独立的与年龄相关的个体差异的处理速度，工作记忆，和回顾性记忆。
This study investigated the role of processing speed and working memory in prospective and retrospective memory (i.e., free recall) performance within old age. The aim was to examine age-related differences in both memory domains within the age range of 65 to 80 years. The sample consisted of 361 older adults from Wave 1 data of the Zurich Longitudinal Study on Cognitive Aging. Using structural equation modeling, prospective memory, free recall, working memory, and processing speed were identified as latent constructs. Age effects were found to be larger for prospective memory than for free recall. Furthermore, when controlling for individual differences in working memory and processing speed, unique age effects remained for prospective, but not retrospective, memory performance. Results indicate that, within old age, prospective memory represents a distinct memory construct that is partially independent of age-related individual differences in speed of processing, working memory, and retrospective memory.
