Memory consolidation as an adaptive process

ET Cowan, AC Schapiro, JE Dunsmoor… - Psychonomic Bulletin & …, 2021 - Springer
We rely on our long-term memories to guide future behaviors, making it adaptive to prioritize
the retention of goal-relevant, salient information in memory. In this review, we discuss …

Memory and sleep: how sleep cognition can change the waking mind for the better

KA Paller, JD Creery… - Annual review of …, 2021 - annualreviews.org
The memories that we retain can serve many functions. They guide our future actions, form a
