Interfering with theories of sleep and memory: sleep, declarative memory, and associative interference

Ellenbogen, J. M., Hulbert, J. C., Stickgold, R., Dinges, D. F., & Thompson-Schill, S. L. (2006). Interfering with theories of sleep and memory: sleep, declarative memory, and associative interference. Current Biology, 16(13), 1290-1294.

Abstract: Mounting behavioral evidence in humans supports the claim that sleep leads to improvements in recently acquired, nondeclarative memories. Examples include motor-sequence learning; visual-discrimination learning; and perceptual learning of a synthetic language. In contrast, there are limited human data supporting a benefit of sleep for declarative (hippocampus-mediated) memory in humans (for review, see). This is particularly surprising given that animal models (e.g.,) and neuroimaging studies (e.g.,) predict that sleep facilitates hippocampus-based memory consolidation. We hypothesized that we could unmask the benefits of sleep by challenging the declarative memory system with competing information (interference). This is the first study to demonstrate that sleep protects declarative memories from subsequent associative interference, and it has important implications for understanding the neurobiology of memory consolidation. »PDF

A Place to Think

Lab Mission

The Memory Dynamics Lab, part of the Psychology Program at Bard College, works to harness the mechanisms responsible for adaptively retrieving, consolidating, and forgetting memories through cognitive neuroscience (including the study of human brainwaves and behavior while awake and asleep). In doing so, we aim to distill and disseminate strategies designed to help learners capitalize on these mental operations, allowing them to better remember when/what they want to remember and forget when/what they want to forget.
