在三个实验中，164名4 - 80岁的被试被试，研究了项目同一性、颜色这三个知觉特征的外显记忆随年龄的变化。和位置，在实验1-2中，特征识别进行了评估的附带学习，类似游戏的游戏任务的浓度。在实验3中，特征识别进行了评估后，故意学习指令使用的纸和纸的任务。整个生命周期的外显记忆功能的形式与特定的知觉特征测试和任务类型项目识别是优秀的，在所有年龄段，但显着较差的老年人比儿童，颜色识别在童年后期达到高峰的游戏任务。这些研究结果表明，外显记忆测试的表现并不是一个一致的倒U形函数的年龄跨越各种功能，外显记忆的表现取决于什么是测量和如何。由于外显记忆通常反映了不同特征的复合，因此外显记忆中与年龄相关的变化不一定与任何自一的功能相对应。(C)2002 Elsevier Science（美国）。
In three experiments with 164 individual, between 4 and 80 years old, we examined age-related changes in explicit memory for three perceptual features-item identity, color. and location, In Experiments 1-2, feature recognition was assessed in an incidental learning, gamelike task resembling the game Concentration. In Experiment 3, feature recognition was assessed using a pencil-and-paper task after intentional learning instructions. The form of the explicit memory function across the life span varied with the particular perceptual feature tested and the type of tasks item recognition was excellent at all ages but was significantly poorer for older adults than children, color recognition peaked in late childhood on the gamelike task. and location recognition peaked in early adulthood on the pencil-and-paper task, These findings indicate that performance on explicit memory tests is not a consistent inverted U-shaped function of age across various features, Explicit memory performance depends on what is measured and how. Because explicit memory typically reflects a composite of different features, age-related changes in explicit memory will not necessarily correspond to the function for any since one.
