[For example,] Walker and colleagues (2003) demonstrated reconsolidation in humans using a procedural motor-skill task that involved finger-tapping a simple sequence (e.g., 4-1-3-2). Twenty-four hours after original exposure to the sequence, participants briefly rehearsed the sequence, thereby reactivating it, and learned a second sequence (e.g., 2-3-1-4). When tested on Day 3, accuracy performance for Sequence 1 was significantly impaired relative to control subjects who did not rehearse Sequence 1 before learning Sequence 2. This shows that the reactivation of the memory for Sequence 1 on Day 2 destabilized it such that a competing motor pattern could interfere with the memory trace. Further, Galluccio (2005) and Galluccio and Rovee-Collier (2005), adopting a conditioning-based paradigm, investigated the fate of reactivated memories in infants trained to kick their foot to activate a mobile. After a delay period, infants were reminded of the event: The moving mobile was presented for a brief period during which it was no longer attached to the baby’s foot. Following reactivation, one group of infants learned to move a novel mobile. One day later, infants who were exposed to the novel mobile showed a modification of the reactivated memory such that they no longer recognized the original mobile reacted only to the novel one. Walker et al. (2003) recently demonstrated reconsolidation effects in humans. Participants were trained on a procedural motor-skill task that involved finger-tapping a simple sequence (e.g., 4-1-3-2). Twenty-four hours later they briefly rehearsed the sequence (reactivating it) and learned a second sequence (e.g., 2-3- 1-4). When tested on Day 3, accuracy performance for Sequence 1 was significantly impaired in comparison to a group of participants who did not rehearse Sequence 1 before learning Sequence 2. This shows that the reactivation of the memory for Sequence 1 on Day 2 destabilized it such that a competing motor pattern could interfere.
