title: The differential effects of stress on memory consolidation and retrieval: a potential involvement of reconsolidation? Theoretical comment on Beckner et al. (2006).
abstract: Previous experiments in the field of stress and memory have suggested a facilitative effect of stress hormones on the consolidation of information but an impairing effect on the retrieval of information. In the article "Stress Facilitates Consolidation of Verbal Memory for a Film but Does Not Affect Retrieval," V. E. Beckner, D. M. Tucker, Y. Delville, and D. C. Mohr (2006) report that exposure to an anticipatory psychological stress enhances consolidation, although it has no impact on the retrieval of previously learned information. This finding is discussed around the importance of the environmental context in which stress is applied and memory is measured. Here, the authors raise the possibility that the enhancing effects of stress on consolidation as reported by Beckner et al. may be explained by the fact that stress can act as a reactivation cue, leading to a 2nd round of consolidation, a process called reconsolidation.
