Conscious Perception And Implicit Memory Formation Of A Narrative Presented During Sleep, Sarah E. Hollywood
Conscious Perception And Implicit Memory Formation Of A Narrative Presented During Sleep, Sarah E. Hollywood
Electronic Thesis and Dissertation Repository
The present study sought to determine the extent of conscious awareness and implicit memory formation of a narrative presented during sleep. Participants were played an excerpt of J.D. Salinger’s Pretty Mouth and Green My Eyes while napping. Afterwards, participants completed a task designed to assess implicit memory to determine if they had formed any memories about words that were either directly stated in the story, or directly related to the plot. Participants who heard the story while asleep responded more quickly to words that had appeared in the story than to words from another story they had not heard. Exactly …

In healthy, young individuals, a reduction in cardiovascular output and a shift from sympathetic to parasympathetic (vagal) dominance is observed from wake into stages of nocturnal and daytime sleep. This cardiac autonomic profile, measured by heart rate variability (HRV), has been associated with significant benefits for cardiovascular health. Aging is associated with decreased nighttime sleep quality and lower parasympathetic activity during both sleep and resting. However, it is not known whether age-related dampening of HRV extends to daytime sleep, diminishing the cardiovascular benefits of naps in the elderly. Here, we investigated this question by comparing the autonomic activity profile between …
Sense Of Purpose In Life And Five Health Behaviors In Older Adults, Eric S. Kim, Koichiro Shiba, Julia K. Boehm, Laura D. Kubzansky
Sense Of Purpose In Life And Five Health Behaviors In Older Adults, Eric S. Kim, Koichiro Shiba, Julia K. Boehm, Laura D. Kubzansky

Accumulating evidence shows that a higher sense of purpose in life is associated with lower risk of chronic conditions and premature mortality. Health behaviors might partially explain these findings, however, the prospective association between sense of purpose and health behaviors is understudied. We tested whether a higher sense of purpose at baseline was associated with lower likelihood of developing unhealthy behaviors over time. Prospective data were from the Health and Retirement Study, a national sample of U.S. older adults. Our sample included 13,770 adults assessed up to five times across eight years. Among people who met recommended guidelines for a …

Make More, Work Less, Michael Sutton
Marriott Student Review
Although the status quo in the business world is to work long hours and supposedly produce more each workweek, studies show that working less and taking appropriately regulated breaks actually lead to more productivity in individuals and businesses as a whole. Specifically companies would be wise to implement a limit of 50 work hours per week, encourage frequent breaks (about 15 minute every hour), and encourage patterns of sufficient sleep. By reducing mental fatigue in your employees, their productivity will increase.
Quality Of Sleep, Stress, And Exercise: Effects Of Environmental And Lifestyle Factors On Spatial Navigation In Older Adults, Hannah Maybrier
Quality Of Sleep, Stress, And Exercise: Effects Of Environmental And Lifestyle Factors On Spatial Navigation In Older Adults, Hannah Maybrier
Arts & Sciences Electronic Theses and Dissertations
Introduction: With increasing age, many adults experience reduced spatial navigation ability, with the most prominent reductions in tasks dependent on the hippocampus. Hippocampal dysfunction may be linked to age-related increases in sleep fragmentation, which results in reduced neurogenesis and long-term potentiation. This project aims to determine if age-related reductions in hippocampal-dependent navigation ability and strategy selection are mediated by impaired sleep. Further, we propose that the effects of sleep on navigation are moderated by psychological stress and physical activity. Methods: 36 older (m: 70, sd: 7) and 33 younger (m: 20, sd: 1.5) adults recorded one week of sleep via …
Formation Of Implicit Memories From A Narrative Played During Sleep, Amanat Ludhar
Formation Of Implicit Memories From A Narrative Played During Sleep, Amanat Ludhar
Undergraduate Honors Theses
Though, it was previously thought that the sleeping brain was dormant, research suggests that participants can process salient stimuli and form implicit memories of simple stimuli (e.g. words) during sleep. Thus, the current study aimed to determine whether participants could form implicit memories of a narrative played during sleep, and what role different sleep stages played in this memory formation. Participants were played a story while taking a nap, and EEG was used to track time spent in different sleep stages. Later, participants completed an implicit memory task where they were asked to differentiate between animal and non-animal words through …
