Levels and rates of acquisition and amounts of forgetting of name-face associations and grocery list items were assessed in a sample of 1,921 normal participants that was divided into five age groups (i.e., 17-39, 40-49, 50-59, 60-69, and 70+). Retrieval was assessed via the consistent long-term retrieval score (CLTR) from the Grocery List Selective Reminding Test (GLSRT). Substantial linear age-associated declines in level of acquisition were noted for both name-face associations and grocery list items. There was a significant age-related drop in rate of acquisition of name-face associations. Remarkably, very little forgetting occurred over a 40-min delay at any age on either measure. There was a significant linear age-related decline in retrieval efficiency for grocery list items, when variance due to both level of acquisition and retention was removed. The nature of age-associated memory decline and its possible neuroanatomic correlates is discussed.
在1921名正常参与者的样本中评估了姓名-面孔联想和购物清单项目的习得水平、习得率以及遗忘量，这些参与者被分为五个年龄组（即17 - 39岁、40 - 49岁、50 - 59岁、60 - 69岁和70岁以上）。通过购物清单选择性提醒测试（GLSRT）中的一致性长期检索分数（CLTR）来评估检索情况。对于姓名-面孔联想和购物清单项目，均发现习得水平存在显著的与年龄相关的线性下降。姓名-面孔联想的习得率存在显著的与年龄相关的下降。值得注意的是，在任何年龄，两种测量方式在40分钟延迟后遗忘都很少。当去除由于习得水平和保持所导致的方差后，购物清单项目的检索效率存在显著的与年龄相关的线性下降。讨论了与年龄相关的记忆衰退的性质及其可能的神经解剖学相关性。
