Decades of research have established that "online" cognitive processes, which operate during conscious encoding and retrieval of information, contribute substantially to individual differences in memory. Furthermore, it is widely accepted that "offline" processes during sleep also contribute to memory performance. However, the question of whether individual differences in these two types of processes are related to one another remains unanswered. We investigated whether working memory capacity…

Individual baseline memory performance and its significance for sleep-dependent memory consolidation
Today, there is little doubt concerning the significance of sleep for memory consolidation. Some studies have suggested, however, that overnight memory consolidation as well as their underpinning
Individual differences in working memory capacity moderate effects of post-learning activity on memory consolidation over the long term
TLDR
The results show that interindividual differences in WMC are a central moderating factor for the effect of post-learning activity on memory retention, and extend findings showing that WMC seems not only to moderate sleep-related but also wakeful resting-related memory consolidation.
The Limited Capacity of Sleep-Dependent Memory Consolidation
TLDR
The finding that retention performance was significantly diminished for the 320 word-pair condition compared to the 160 word- Pair condition in the sleep group, makes it tempting to speculate that with increasing loads of information encoded during wakefulness, sleep might favor processes of forgetting over consolidation.
General intelligence predicts memory change across sleep
TLDR
The present research suggests that g not only reflects the capability for online cognitive processing, but also reflects capability for offline processes that operate during sleep.
What drives sleep-dependent memory consolidation: Greater gain or less loss?
TLDR
The sleep condition showed more items gained and fewer items lost than did the wake condition, and the difference between the conditions in lost items was greater than the difference in gain, suggesting that loss prevention may primarily account for the effect of sleep on declarative memory consolidation.
The contributions of sleep-related consolidation to emotional item and associative memory.
TLDR
The objectives of the present thesis aimed to generate a more comprehensive understanding of the differential contributions of consolidation processes during SWS and REM sleep to (non-)emotional item and associative memory retention.
About sleep's role in memory.
TLDR
This review aims to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings.
Hippocampal Contributions to Declarative Memory Consolidation During Sleep
TLDR
Evidence that during sleep the reactivation of newly acquired neuronal traces has lasting implications for memory transformation and stabilization is reviewed, showing that memories can be selectively targeted and modified using learning-related stimuli.
Vast amounts of encoded items nullify but do not reverse the effect of sleep on declarative memory
TLDR
There is evidence against sleep having a detrimental effect on the retention of declarative memory at high information loads and it is argued that forgetting occurs in both wake and sleep states through different mechanisms, i.e., through increased interference and through global synaptic downscaling.

Sleep Contributes to the Strengthening of Some Memories Over Others, Depending on Hippocampal Activity at Learning
TLDR
The data indicate that relevant items that subjects strived to memorize are consolidated during sleep to a greater extent than items that participants did not intend to learn.
The Sleeping Brain's Influence on Verbal Memory: Boosting Resistance to Interference
TLDR
By introducing interference after sleep, this study confirms an experimental paradigm that demonstrates the active role of sleep in consolidating memory, and unmasks the large magnitude of that benefit.
Sleep spindles and their significance for declarative memory consolidation.
TLDR
Results indicate that increased sleep stage 2 spindle activity is related to an increase in recall performance and, thus, may reflect memory consolidation in stage 2 sleep.
Consolidating the Effects of Waking and Sleep on Motor-Sequence Learning
TLDR
When training begins in the morning, motor-sequence performance deteriorates across wakefulness and recovers after sleep, whereas performance remains stable across both sleep and subsequent waking with evening training, which challenges an influential model of memory consolidation defined by a time-dependent stabilization phase and a sleep-dependent enhancement phase.
Learning-Dependent Increases in Sleep Spindle Density
TLDR
Results indicate that spindle activity during non-REM sleep is sensitive to previous learning experience, and spindle density was correlated to recall performance both before and after sleep.

TLDR
Increasing central nervous cholinergic activation during SWS-rich sleep by posttrial infusion of 0.75 mg of the cholinesterase inhibitor physostigmine completely blocked SWs-related consolidation of declarative memories for word pairs in human subjects, in line with predictions that a low Cholinergic tone duringSWS is essential forDeclarative memory consolidation.
Effects of early and late nocturnal sleep on priming and spatial memory.
TLDR
It appears that earlySleep dominated by SWS facilitates consolidation of declarative memory whereas late sleep dominated by REM sleep facilitates consolidationof nondeclarativeMemory.
Reduced false memory after sleep.
TLDR
Three experiments are reported showing that sleep reduces false memories in the Deese-Roediger-McDermott (DRM) memory illusion, and the benefits of sleep are extended to include increased accuracy of episodic memory.
