The Effects Of Sleep And Memory

This literature review will identify and address ongoing themes seen throughout several articles regarding sleep and memory, specifically the effects that sleep has on memory. Throughout every article the research shows that sleep is found to improve memory. However, the question is what kind of memory is supported by sleep and what type of sleep is best for improving memory. In the articles, research studies show the effects and ask what type of sleep is best for memory, and what memory is most positively influenced. The conclusion is that as sleep progresses into slow wave sleep, the outcome on memory is sufficient and necessary, specifically its most influential effects, on episodic memory.
There are many different types of memory which

Abel and Bauml (2013) conducted research examining sleeps effect on different types of memory interference, retroactive and proactive. Retroactive interference in memory is the effect that new information and learning has on recalling the previously learned information that already exists in the brain. Proactive refers to previously learned material how it interferes with later obtaining of information and learning. The researchers tested their hypothesis by showing the participants one of two lists. The lists were either a single list, which meant there was no interference, or two lists that would interfere with one another. After the lists were presented, the participants were placed in a condition of either sleep or wake. After the period of sleep or wake, participants were tested on their recall and what was interfered with. The results found that sleep reduced both kinds of interference (Abel & Bauml, 2013). Episodic memory is often affected by interference, again supporting the idea of being a beneficiary of sleep. Throughout these discussed studies, there was no manipulation or control over the types of sleep, but many researchers hone in on the specific types of sleep and the roles which they …show more content…
The research and discoveries go further, to say that precisely slow wave sleep is the most positively influential type of sleep on memory consolidation. To continue to be more concise, we can emphasize that especially episodic memory is improved by slow wave sleep. During slow wave sleep, the memories people obtain are enhanced through sleep, by their movement from the hippocampus to neocortical sites where they will encode and stay in long term memory. Because episodic memory is greatly influenced and related to the hippocampus, it is not a big surprise that episodic memory sees the biggest benefit from sleep. Although we have come to a better understanding of sleep and memory, there are still many stones left unturned which will be explored down the road. New research could lead practices to improve learning with the help of new knowledge on sleep and memory. To conclude, it is continuously proven that in consolidating memories, slow wave sleep will be the most influential, and have the largest effect on memories which are
