Data from samples of adults selected to be representative of the U.S. population were examined to investigate issues related to the breadth and timing of age-related effects on memory and other cognitive functions. The results suggest that memory aging begins in early adulthood, that it overlaps with other aspects of cognitive aging, and that it can occur without accompanying increases in between-person variability. These findings imply that it is important to consider factors occurring early in life when attempting to understand the causes of memory and cognitive impairments apparent late in life.
对选取的具有美国人口代表性的成年人样本数据进行了研究，以调查与年龄相关的对记忆及其他认知功能影响的广度和时间相关的问题。结果表明，记忆老化始于成年早期，它与认知老化的其他方面重叠，并且它可以在人际变异性不增加的情况下发生。这些发现意味着，在试图理解生命后期出现的记忆和认知障碍的原因时，考虑生命早期出现的因素很重要。
