Prospective remembering reflects the ability of an individual to form and later realize intentions that must be delayed over minutes, hours, or days. A substantial body of literature, primarily based upon the findings of behavioral studies, indicates that there are robust declines in the efficiency of prospective remembering in later adulthood. However, the cognitive and neural mechanisms mediating age-related deficits in prospective remembering are not well understood. In this review we consider evidence from recent behavioral and electrophysiological studies indicating that decreases in the efficiency of prospective memory in older adults results from age-related differences in those neural mechanisms supporting the encoding of intentions into memory and the detection of prospective memory cues in the environment.
前瞻性记忆反映了个体形成并随后实现意图的能力，这些意图必须在数分钟、数小时或数天内延迟执行。大量主要基于行为研究结果的文献表明，成年后期前瞻性记忆的效率会显著下降。然而，介导前瞻性记忆中与年龄相关缺陷的认知和神经机制尚不清楚。在这篇综述中，我们考虑了来自近期行为和电生理研究的证据，这些证据表明老年人前瞻性记忆效率的下降是由于支持将意图编码到记忆中以及检测环境中的前瞻性记忆线索的神经机制存在与年龄相关的差异。
