Retrieval is greater if new learning is followed by a period of wakeful rest, minimising the likelihood of retroactive interference. It is not known if this benefit extends to recollection of both gist and peripheral details, nor whether age affects the benefit of wakeful resting in either of these types of recollection. Forty-five younger and forty older adults were presented with prose passages for later recall followed by a period of either interference or wakeful resting. Younger participants outperformed older participants in remembering peripheral details, but not on gist memory. Wakeful resting led to higher overall recollection in both age groups, both for gist and for peripheral details. Also, wakeful resting was more beneficial for gist than peripheral memory in older but not younger adults. We discuss these novel findings and their theoretical implications for a memory consolidation account of the benefits of wakeful resting.
如果新学习后有一段清醒的休息时间，检索效果会更好，从而最大程度地减少后摄干扰的可能性。目前尚不清楚这种益处是否扩展到对主旨和外围细节的回忆，也不知道年龄是否会影响清醒休息对这两种回忆类型的益处。45 名年轻参与者和 40 名年长参与者接受散文段落的呈现，之后进行回忆，回忆前有干扰或清醒休息阶段。年轻参与者在回忆外围细节方面的表现优于年长参与者，但在主旨记忆方面则不然。清醒休息在两个年龄组中都导致了更高的整体回忆，无论是主旨还是外围细节。此外，在年长参与者中，清醒休息对主旨记忆的益处大于对外围记忆的益处，但在年轻参与者中则不然。我们讨论了这些新发现及其对清醒休息益处的记忆巩固理论解释的理论意义。
