Selectively retrieving a subset of previously studied information can cause forgetting of related, nonretrieved information. Such retrieval-induced forgetting (RIF) has typically been attributed to inhibitory control processes. Examining participants with a mean age of about 70 years, previous work reported intact RIF in older adults, suggesting efficient inhibition in older adults' episodic memory. We replicated the prior work by finding reliable RIF in young-old participants (60-75 years), but additionally found RIF to decline with increasing age and to be inefficient in old-old participants (above 75 years). The results support the proposal of an inhibitory deficit in (very) old age.
选择性地提取之前研究过的信息的一个子集可能会导致相关的、未被检索到的信息被遗忘。这种检索诱导的遗忘（RIF）通常归因于抑制控制过程。在对平均年龄约为 70 岁的参与者进行的研究中，之前的工作报告称老年人的 RIF 没有受损，这表明老年人的情景记忆具有有效的抑制能力。我们通过在年轻老年人（60-75 岁）中发现可靠的 RIF 复制了之前的工作，但此外还发现 RIF 随着年龄的增长而下降，并且在老年老年人（75 岁以上）中效率低下。这些结果支持了（非常）老年期存在抑制缺陷的假说。
