学习和记忆新信息的能力会沿着一生而下降。经验证据表明，这种缺陷在不同类型的记忆中发生的不均匀。情景记忆是指在确定的时间和空间背景下记住我们自己经历的能力，特别容易受到衰老的影响。情节信息可以在有或没有情节事件被编码时发生的上下文信息的情况下被检索。人们一致认为，随着年龄的增长，与情节事件相关的源信息比事件更容易被遗忘;然而，关于这种下降开始的年龄，源记忆下降的速度沿着生活或可能的变化，由于年龄的增长，在编码源信息的神经生理活动中，随后正确检索，没有共识。为了回答前两个问题，我们对552名20 ~ 80岁的受试者进行了一项行为研究，该研究提供了证据，证明源记忆开始衰退的确切年龄以及这种记忆沿着一生的衰退速度。为了解决最后一个问题，记录事件相关电位，而年轻人和老年人编码的源信息，以调查老年人是否产生不同的记忆痕迹，年轻人在编码。(c)2008 Elsevier B.

The ability to learn and remember new information declines along life. Empirical evidence reveals that this deficit occurs unevenly with different types of memory. Episodic memory, which is referred to as the ability to remember our own experiences in a determined temporal and spatial context, is especially vulnerable to aging. Episodic information can be retrieved with or without the context information that took place when the episodic event was encoded. There is agreement that, with advancing age, the source information related to an episodic event is more susceptible to be forgotten than the event; however, there is no consensus regarding the age at which this decline begins, the speed of source-memory decline along life or the possible changes, due to aging, in neurophysiological activity during encoding of source information that is subsequently correctly retrieved. In an attempt to answer the first two issues, a behavioral study with 552 subjects from 20 to 80 years of age was conducted, which provided evidence of the exact age at which source memory starts to decline and of the speed of this memory loss along life. To address the last question, event-related potentials were recorded while young and old adults encoded source information, to investigate whether older adults generate memory traces different from young adults during encoding.
