Previous research has shown sleep-dependent memory consolidation in children on tasks such as lexical integration of novel words (Henderson et al, 2012) and spatial location learning (Kurdziel et al, 2013). This appears to be limited to declarative memory tasks; procedural learning tasks do not show the same sleep-related benefit in children that is seen in adults (Fischer et al, 2007; Wilhelm et al, 2008)
This turned out to be driven entirely by the word pairs without source memory; where the item and source had both been remembered, no difference was seen. The authors interpreted their findings in the context of less distinct encoding in children leading to more rapid unbinding of items and sources. This does not explain why item-only memory declines across sleep in children but item-source memory remains intact, and why the opposite pattern is seen in adults
