提取门控是指根据行为目标调节单个记忆事件特征提取的能力。最近的研究结果表明，年轻的成年人从事检索门控衰减的任务无关的功能的一集的代表。在这里，我们检查是否检索门控随年龄而变化。年轻人和老年人偶然编码的话叠加在场景或混乱的背景，显示在三个空间位置之一。参与者随后接受了fMRI，因为他们完成了两项记忆任务：背景任务，测试单词背景的记忆，以及位置任务，测试单词位置的记忆。采用单变量和多变量的方法，我们表明，年轻人，但不是老年人，表现出衰减恢复的场景信息时，它是目标无关的（在位置任务）。此外，仅在年轻人中，背景任务期间海马旁位置区场景恢复的强度与项目和源记忆表现有关。总之，这些发现表明，参与提取门控的能力与年龄有关。
Retrieval gating refers to the ability to modulate the retrieval of features of a single memory episode according to behavioral goals. Recent findings demonstrate that younger adults engage retrieval gating by attenuating the representation of task-irrelevant features of an episode. Here, we examine whether retrieval gating varies with age. Younger and older adults incidentally encoded words superimposed over scenes or scrambled backgrounds that were displayed in one of three spatial locations. Participants subsequently underwent fMRI as they completed two memory tasks: the background task, which tested memory for the word’s background, and the location task, testing memory for the word’s location. Employing univariate and multivariate approaches, we demonstrated that younger, but not older adults, exhibited attenuated reinstatement of scene information when it was goal-irrelevant (during the location task). Additionally, in younger adults only, the strength of scene reinstatement in the parahippocampal place area during the background task was related to item and source memory performance. Together, these findings point to an age-related decline in the ability to engage retrieval gating.
