我们提出了一项测试，以检验在记忆提取过程中与年龄相关的干扰管理差异是否可以至少部分地解释为老年人抑制机制的减少。我们通过测量情境模型表征的易取性来进行测试，这些情境模型表征是前一次试验的干扰源，但包含当前试验的目标信息。先前的研究表明，与不相关的对照相比，在这些条件下的情境模型提取表现出抑制效应。在目前的研究中，这一效应在年轻人中重复，但在老年人中没有；同时，老年人表现出比年轻人更大的总体提取干扰。这一模式与老年人抑制性加工能力下降的观点是一致的，这也适用于记忆提取。
We present a test of whether age-related differences in the management of interference during memory retrieval can be explained, at least in part, by decreased inhibitory mechanisms in older adults. We conducted this test by measuring the ease of retrieval of situation model representations that were sources of interference on the preceding trial but that contained the target information for the current trial. Prior research has shown that situation model retrieval under these conditions exhibits inhibition relative to an unrelated control. This effect was replicated in the current study for younger but not older adults; at the same time, the older adults showed greater overall retrieval interference than the younger adults. This pattern is consistent with the idea that there are declines in inhibitory processing in older adults, and that this applies to memory retrieval.
