The Domain-Generality And Durability Of Efficient Learning, Christopher Zerr

Arts & Sciences Electronic Theses and Dissertations

People differ in how quickly they learn information and how long they remember it, and a common finding in the literature is that a quicker rate of learning coincides with better retention for the learned material. Zerr and colleagues (2017) termed the relation between learning rate and retention as learning efficiency, with more efficient learning representing both a faster acquisition rate and better memory performance after a delay. Zerr et al. also demonstrated in separate experiments that how efficiently someone learns is stable across a range of days and years. The current thesis includes two experiments addressing additional questions …

The Twilight Zone: The Confluence Of Childhood Scenes And Future Anxiety, Jongwon Bae

Theses and Dissertations

Jongwon Bae’s paintings reflect his childhood memories as an archive that is to be repressed until it manifests itself in uncertain ways as it becomes confluent with the anxiety about the future.

Passing, Paul Kelley

The STEAM Journal

Passing is a Site-specific public installation assembled with plastic and an iPad. At its center, the iPad displays a video loop of a human image repeatedly walking in and out of the frame. The work maintains my foundational interest in having the viewer slow down to have a more thoughtful and absorptive experience with the work and surrounding space – continuing my practice of challenging viewer’s expectations and putting them in a position to stop and question.

Maybe That's What It Means, Anael Berkovitz

Theses and Dissertations

Anael Berkovitz explores personal and collective memory through the use of storytelling and interpretation. Focusing on how identity is shaped by stories, her three part video details the nomadic nature of her own family, the obfuscation of language in translation and the incorporation of an invasive species into a culture.

A Chair In The Woods, Victoria Dolloff

Theses and Dissertations

Victoria Dolloff's MFA Thesis considers traces of play and perception in the development of her artwork, exploring the idea of reorientation through subtleties of the absurd. Her installation Untitled (Landscape) questions object as place and place as memory utilizing fragmentation as reconstruction.

Cunningly Sweated: Creation, Memory, And Time In Faulkner's Mosquitoes, Joseph C. Morecraft Iv

English Dissertations

This study focuses on the early fiction of William Faulkner, particularly Mosquitoes. Understood in critical context, this novel suffers from retrospective bias. That is, I believe that the brilliant work that immediately (and continually) succeeded this novel provided a critical comparison that made it impossible to ascribe the appropriate value that this second novel truly deserves. Mosquitoes was not only a necessary portal and stepping stone to his later/greater fiction, but it also stands on its own as a brilliant experiment allowing Faulkner to free himself from bonds of fragmented mimesis by submerging himself in his own social, literary, …

Reversible Cooling-Induced Deactivations To Study Cortical Contributions To Obstacle Memory In The Walking Cat, Carmen Wong, Stephen G. Lomber

Brain and Mind Institute Researchers' Publications

On complex, naturalistic terrain, sensory information about an environmental obstacle can be used to rapidly adjust locomotor movements for avoidance. For example, in the cat, visual information about an impending obstacle can modulate stepping for avoidance. Locomotor adaptation can also occur independent of vision, as sudden tactile inputs to the leg by an expected obstacle can modify the stepping of all four legs for avoidance. Such complex locomotor coordination involves supraspinal structures, such as the parietal cortex. This protocol describes the use of reversible, cooling-induced cortical deactivation to assess parietal cortex contributions to memory-guided obstacle locomotion in the cat. Small …

Modeling And Implementation Of Hfo2-Based Ferroelectric Tunnel Junctions, Spencer Allen Pringle

Theses

HfO2-based ferroelectric tunnel junctions (FTJs) represent a unique opportunity as both a next-generation digital non-volatile memory and as synapse devices in braininspired logic systems, owing to their higher reliability compared to filamentary resistive random-access memory (ReRAM) and higher speed and lower power consumption compared to competing devices, including phase-change memory (PCM) and state-of-the-art FTJ. Ferroelectrics are often easier to deposit and have simpler material structure than films for magnetic tunnel junctions (MTJs). Ferroelectric HfO2 also enables complementary metal-oxide-semiconductor (CMOS) compatibility, since lead zirconate titanate (PZT) and BaTiO3-based FTJs often are not.

No other groups have yet demonstrated a HfO2-based FTJ …

Sleep-Dependent Motor Sequence Memory Consolidation In Individuals With Periodic Limb Movements, Valya Sergeeva, Jeremy Viczko, Laura B. Ray, Adrian M. Owen, Stuart M. Fogel

BrainsCAN Publications

© 2017 Elsevier B.V. Periodic limb movements (PLMs) during sleep increase with age and are associated with striatal neurodegeneration and dopamine deficiency. Limb movements are often associated with disruptions to non-rapid eye movement (NREM) sleep. Motor skill memory consolidation recruits the striatum, and learning-dependent striatal activation is associated with NREM sleep. Therefore, we investigated whether de novo individuals who significantly experience elevated levels of PLMs but have not been formally diagnosed with periodic limb movement disorder had learning and sleep-related memory deficits and whether these deficits were related to sleep quality and symptom severity. In total, 14 adults with significantly …

Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins

Theses and Dissertations

The average lifespan is constantly increasing with the advent of new medical techniques, and age-related cognitive decline is becoming a prevalent societal issue. Even during healthy aging, humans and rats exhibit progressive deficits in episodic/declarative memory. In laboratory rats, age-related memory impairment can be assessed with trace fear conditioning (TFC). Recent research implicates ubiquitin proteasome system-mediated protein degradation in the synaptic plasticity supporting memory formation and retrieval. In rats, aging leads to decreased basal proteolytic activity in brain structures known to support the acquisition and retrieval of trace fear memories, and our preliminary data suggests activity-dependent proteasome activity declines in …

The Impact Of Delay On Retrieval Success In The Parietal Memory Network, Nathan Anderson

Arts & Sciences Electronic Theses and Dissertations

Recent work has identified a Parietal Memory Network (PMN), which exhibits regular patterns of activation during memory encoding and retrieval. Among these characteristic patterns, this network displays a strong “retrieval success” effect, showing greater activation for correctlyremembered studied items (hits) compared to correctly-rejected novel items (CRs). To date, most relevant studies have used short retention intervals. Here, we ask if the retrieval success effect seen in the PMN would remain consistent over a delay. Twenty participants underwent fMRI while encoding and recognizing scenes. Greater activity for hits than for correctly-rejected lures within PMN regions was observed after a short delay …

The Effects Of Repeated Lineups And Delay On Eyewitness Identification, Wenbo Lin

Arts & Sciences Electronic Theses and Dissertations

Prior eyewitness research has examined the effects of repeated identification procedures and delays on eyewitness identification, but these studies have either confounded these two factors or studied them in isolation. Experiment 1 attempted to disentangle these factors through systematic manipulations of the number of repeated lineups and the length of delay between the original event and the first lineup. Experiment 2 examined whether the length of delay between two lineups (Lineups 1 and 2) affects the subsequent lineup identification decisions. We found that people were more inclined to choose when a lineup was repeated. A longer delay between the crime …

Widespread Theta Synchrony And High-Frequency Desynchronization Underlies Enhanced Cognition., E. A. Solomon, J. E. Kragel, Michael R. Sperling, Ashwini Sharan, G. Worrell, M. Kucewicz, C. S. Inman, B. Lega, K. A. Davis, J. M. Stein, B. C. Jobst, K. A. Zaghloul, S. A. Sheth, D. S. Rizzuto, M. J. Kahana

Department of Neurology Faculty Papers

The idea that synchronous neural activity underlies cognition has driven an extensive body of research in human and animal neuroscience. Yet, insufficient data on intracranial electrical connectivity has precluded a direct test of this hypothesis in a whole-brain setting. Through the lens of memory encoding and retrieval processes, we construct whole-brain connectivity maps of fast gamma (30-100 Hz) and slow theta (3-8 Hz) spectral neural activity, based on data from 294 neurosurgical patients fitted with indwelling electrodes. Here we report that gamma networks desynchronize and theta networks synchronize during encoding and retrieval. Furthermore, for nearly all brain regions we studied, …

Exercise, Learning And Emotional Health: Interdisciplinary Approaches To Translational Action, Tessa L. Koschel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exercise positively effects physical, psychological and neurological wellbeing. Though the population at large is becoming increasingly aware of the multi-faceted benefits of exercise, the majority of people fail to meet daily exercise recommendations. Largely, demands of everyday life such as work, school and family take priority over fitness. The issue therefore becomes a matter of time. In a world of media multi-tasking and immediate gratification, the challenge to health professionals becomes incorporation and manipulation of these consistencies to improve exercise uptake and adherence. Focus must shift from the idea of making additional time for exercise, to adding exercise to time …

The Effect Of Telling Lies On Belief In The Truth, Danielle C. Polage

All Faculty Scholarship for the College of the Sciences

The current study looks at the effect of telling lies, in contrast to simply planning lies, on participants’ belief in the truth. Participants planned and told a lie, planned to tell a lie but didn’t tell it, told an unplanned lie, or neither planned nor told a lie (control) about events that did not actually happen to them. Participants attempted to convince researchers that all of the stories told were true. Results show that telling a lie plays a more important role in inflating belief scores than simply preparing the script of a lie. Cognitive dissonance may lead to motivated …

The Things We Remember: Interpreting The Virginia Memorial, Olivia Ortman

The Gettysburg Compiler: On the Front Lines of History

When I was in high school, I read The Things They Carried for my English class. It is a fiction book about the Vietnam War written by a Vietnam veteran. The author, Tim O’Brien, had the life experiences to write an autobiography based on true events, but he chose fiction as his vehicle. He explains this choice in one of the chapters in his book. O’Brien stated that, in an ironic way, fiction allowed him to share more truth than reality. His made-up stories allowed him to create the feelings and meanings of the war that his real experiences couldn’t …

Material Forms: What Is Really Going On? Shaping Who We Are And What We Do, Vicky J. Grube

The Qualitative Report

Using visual and ethnographic methods the author forms a connection between materiality and the memories of childhood. The researcher begins by asking the question, “Can a studio environment create encounters between a researcher and preschool children that deepen understanding of culture?” To this end, the researcher engaged in sensory research practices through ethnographic methods in a preschool art studio. Through free choice art making, children were found expressing their emotions and demonstrating an awareness of adult culture. In particular, the researcher’s encounter with four-year old George was enriched through sensory participation and triggered embodied and empathetic knowing. As it happens, …

Warriors Of Bronze: The Virginia Monument And Remembrance Day, Zachary A. Wesley

The Gettysburg Compiler: On the Front Lines of History

Memory is a peculiar thing. To recall it is to remember, and there are two days dedicated to this activity in mid-November in Gettysburg. On November 18 and 19, reenactors and keynote speakers gather here to honor the sacrifices of millions of soldiers and sailors during the American Civil War. November 19 rings throughout the history of oration as the date of Lincoln’s famous Gettysburg Address, itself an exercise in remembrance. The recent Remembrance and Dedication Days have encouraged me to think of my work on the Virginia Monument Wayside Project in light of the celebrations. Just as much as …

Improving The Present By Studying The Past: Killed At Gettysburg Remembers O’Rorke And Phelps, Ryan D. Bilger

The Gettysburg Compiler: On the Front Lines of History

This semester, I have had the honor of working on the Civil War Institute’s Killed at Gettysburg project, hosted at killedatgettysburg.org. The project seeks to document the lives and legacies of soldiers who died during the three days of fighting in July 1863. I am happy to be contributing to Killed at Gettysburg again, as I strongly connected with the project when I worked on it for Dr. Carmichael’s Gettysburg class last semester. [excerpt]

Remembrance Day: History, Memory And The 20th Maine, Savannah A. Labbe

The Gettysburg Compiler: On the Front Lines of History

Every November, on the Saturday closest to the 19th, the town of Gettysburg celebrates Remembrance Day. This day is held in memory of those who fought and died at the Battle of Gettysburg and during the Civil War as a whole. On November 19th, crowds gather to celebrate Lincoln’s Gettysburg Address and his dedication of the Gettysburg National Cemetery. These events pose a few very important questions: why do we still remember the Civil War in this manner? Why do we find it so important to have an entire day dedicated just to Civil War soldiers? Why does Civil War …

Adverse Childhood Experiences And Its Association With Cognitive Impairment In Non- Patient Older Population, Mohini D. Dutt

USF Tampa Graduate Theses and Dissertations

This study explores cognitive impairment and its correlation to early- life adverse experiences in non-patient population between the ages of 50 to 65. This developmental approach and observational study design explores cognition in pre-clinical Alzheimer’s disease (AD). Using a standardized neuropsychological instrument, the Montreal Cognitive Assessment (MoCA) and clinically administered questionnaire, the ACE (Adverse Childhood Experiences), I hypothesized that participants with high ACE scores will inversely have low MoCA scores.

My goal was to use a multiple linear regression model with 3 covariates and 1 predictor of interest (ACEs). At 80% power, a sample size of 40 was calculated as …

Patient Experiences In Intensive Care Units: A Systematic Review, Serpil Topçu, Şule Ecevit Alpar, Bilgi Gülseven, Ayda Kebapçı

Patient Experience Journal

The aim of this systematic review is to analyze the data gathered from studies conducted to determine patient experiences in intensive care and levels of the recollection of the intensive care period that were published between December, 1998 – April, 2013. The systematic review was carried out screening of the related publications. The findings of the systematic review were studied under the following two titles: “remembering the intensive care period” and “recalled experiences” of patients. Studying 15 papers which were found suitable to the inclusion criteria of the review indicated that majority of the patients had recollection of the intensive …

The Effects Of Sports Related Head Impact On Balance And Neurocognitive Functions, Shaquanda D. Ross-Simmons, Michelle L. Vieyra, Abhishek Jain, Keri Weed

Journal of the South Carolina Academy of Science

The goal of this study was to investigate the effects of sports-related head injury on balance, attention, and memory. Reliable differences have been found using measures that directly tap into brain functioning, such as the auditory oddball task combined with EEG recording. We hypothesized that athletes reporting a diagnosed concussion or participation in high-risk sports would have compromised balance and neurocognitive functioning compared to athletes in low risk sports. Forty-five undergraduate participants were identified as either concussed, non-concussed in high-risk sports, or non-concussed in low-risk sports using a survey of athletic history, head trauma and demographics. The Biopac MP36 system, …

Fantasy Frontier: Old West Theme Parks And Memory In California, Amanda Tewes

Doctoral Dissertations

This study examines sites of Old West tourism—specifically the three California theme parks of Knott’s Berry Farm, Calico Ghost Town, and Frontier Village—as avenues through which the myth of “the West” gets propagated, even among the people of the American West, and even if these sites do not reflect the actual history of the region. California’s Old West theme parks act as windows into mid-twentieth-century cultural conflicts of politics and identity within the state. But these sites are artifacts of a particular historical moment and their fantasy of the Old West memorializes mid-century renderings of the past rather than nineteenth-century …

Associations Between Self-Reported Sleep Quality And White Matter In Community-Dwelling Older Adults: A Prospective Cohort Study, Claire E. Sexton, Enikő Zsoldos, Nicola Filippini, Ludovica Griffanti, Anderson M. Winkler, Abda Mahmood, Charlotte L. Allan, Anya Topiwala, Simon D. Kyle, Kai Spiegelhalder

School of Medicine Publications and Presentations

Both sleep disturbances and decline in white matter microstructure are commonly observed in ageing populations, as well as in age-related psychiatric and neurological illnesses. A relationship between sleep and white matter microstructure may underlie such relationships, but few imaging studies have directly examined this hypothesis. In a study of 448 community-dwelling members of the Whitehall II Imaging Sub-Study aged between 60 and 82 years (90 female, mean age 69.2 ± 5.1 years), we used the magnetic resonance imaging technique diffusion tensor imaging to examine the relationship between self-reported sleep quality and white matter microstructure. Poor sleep quality at the time …

Finding Meaning In The Flag: Furl That Banner, Olivia Ortman

The Gettysburg Compiler: On the Front Lines of History

Hello again, readers. I hope you enjoyed the summer and are now as eager as I am to jump back into our conversation about the Confederate flag. Although I spent the summer at Minute Man NHP, the Civil War was never far from my mind. Even in a northern park dedicated to the American Revolution, I still heard a lot about the Confederate monument debates, and as I spoke with visitors who were following this topic in the news, I was reminded of a similar debate several years ago concerning the Confederate flag.

Eliciting A Perpetrator Description Using The Cognitive Interview: Influences On Investigative Utility, Geri Satin

FIU Electronic Theses and Dissertations

The Cognitive Interview (CI) has been shown in over one hundred studies to enhance eyewitness recall. However, no study has explored whether the CI improves police job performance. The current study was the first to test the practical value of the CI in a criminal investigation, testing participants’ performance on key police tasks using either a perpetrator description elicited from a CI or from a standard police interview (SI).

In an earlier study, student witnesses were exposed to a simulated robbery and were then interviewed using either a CI or an SI to elicit a description of the robber (comprised …

Documenting An Imperfect Past: Examining Tampa's Racial Integration Through Community, Film, And Remembrance Of Central Avenue, Travis R. Bell

USF Tampa Graduate Theses and Dissertations

This research examines the Civil Rights Movement in Tampa, Florida through documentary film to recognize an imperfect past and visually reconstruct Central Avenue as a physical and Thirdspace site of remembrance located at an intersection of race and community. Motivated by an ethnographic approach and through community engagement, Tampa Technique: Rise, Demise, and Remembrance of Central Avenue is a 54-minute film that explores Central Avenue’s rise to prominence through segregation, its physical and symbolic demise as a racialized site of communal space, and how it is remembered through collective and public memory in the location it once occupied. Documentary film …

Identification Of Genes That Maintain Behavioral And Structural Plasticity During Sleep Loss, Laurent Seugnet, Stephane Dissel, Matthew S. Thimgan, Lijuan Cao, Paul J. Shaw

Biological Sciences Faculty Research & Creative Works

Although patients with primary insomnia experience sleep disruption, they are able to maintain normal performance on a variety of cognitive tasks. This observation suggests that insomnia may be a condition where predisposing factors simultaneously increase the risk for insomnia and also mitigate against the deleterious consequences of waking. To gain insight into processes that might regulate sleep and buffer neuronal circuits during sleep loss, we manipulated three genes, fat facet (faf), highwire (hiw) and the GABA receptor Resistance to dieldrin (Rdl), that were differentially modulated in a Drosophila model of insomnia. Our results indicate …
