Consolidation of episodic memories during sleep: long-term effects of retrieval practice

Racsmany, M, Conway, M. A. and Demeter, G (2010). Consolidation of episodic memories during sleep: long-term effects of retrieval practice. Psychological Science, 21(1), pp. 80-85. doi: 10.1177/0956797609354074


Two experiments investigated the long-term effects of retrieval practice. In the retrieval-practice procedure, selected items from a previously studied list are repeatedly recalled. The typical retrieval-practice effects are considerably enhanced memory for practiced items accompanied by low levels of recall, relative to baseline, for previously studied items that are associated with the practiced items but were not themselves practiced. The two experiments demonstrated that the former effect persisted over 12 hr; the latter effect also persisted over 12 hr, but only if a period of nocturnal sleep occurred during the retention interval. We propose that consolidation processes occurring during sleep, and possibly featuring some form of off-line rehearsal, mediate these long-term effects of retrieval practice.
