The Neural Correlates And Temporal Dynamics Of Cued Fear Generalization, Kelsey Nicole Wilson Aug 2019

The Neural Correlates And Temporal Dynamics Of Cued Fear Generalization, Kelsey Nicole Wilson

Theses and Dissertations

Fear generalization, the generalization of fear to innocuous stimuli, is a characteristic component of pathological anxiety. For example, after returning from war, a person might begin to experience fear in response to the sound of fireworks, a stimulus typically regarded as safe. When excessive, “overgeneralization” serves as a core feature of fear and anxiety-related disorders, such as PTSD. The present collection of studies sought to investigate the neural correlates and temporal dynamics of fear generalization in humans.

The first study sought to investigate the causal role of the ventromedial prefrontal cortex (vmPFC) and hippocampus in the generalization of fear. Contrary ...


Familiarization Through Ambient Images Alone, Nia Imani Gipson May 2019

Familiarization Through Ambient Images Alone, Nia Imani Gipson

Theses and Dissertations

The term “ambient images” has begun to show up in much of the current literature on facial recognition. Ambient images refer to naturally occurring views of a face that captures the idiosyncratic ways in which a target face may vary (Ritchie & Burton, 2017). Much of the literature on ambient images have concluded that exposing people to ambient images of a target face can lead to improved facial recognition for that target face. Some studies have even suggested that familiarity is the result of increased exposure to ambient images of a target face (Burton, Kramer, Ritchie, & Jenkins, 2016). The current study ...


Liable To Change, Jody Travis Thompson May 2019

Liable To Change, Jody Travis Thompson

Theses and Dissertations

Liable to Change is a body of paintings in which I explore diverse approaches to the representation of visual space. Depictions of space and movement change throughout the pictures by combining various artistic conventions, such as trompe l’oeil realism and non-objective, geometric abstraction. Oil paint, resin, beeswax, and other materials create built-up surfaces which contain the history of their making. Interaction between various finishes and light on these surfaces changes based on the viewers' proximity to the painting. Images of monkey bars, lattice, golden ratio and flower of life patterns provide a structure through which line, form, and space ...


The Interaction Of Individual Working Memory Capacity With Cognitive Linguistics-Based And Translation-Based Instructional Treatments During The Acquisition Of Polysemous L2 Spanish Spatial Prepositions, Joseph F. Letexier Apr 2019

The Interaction Of Individual Working Memory Capacity With Cognitive Linguistics-Based And Translation-Based Instructional Treatments During The Acquisition Of Polysemous L2 Spanish Spatial Prepositions, Joseph F. Letexier

Theses and Dissertations

The present study investigated three areas in SLA related to the acquisition of polysemous L2 Spanish spatial prepositions. These three areas were (1) the effect of instructional method on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions, (2) the effect of working memory capacity on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions, and (3) the effects resulting from the interaction of working memory capacity with instructional method on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions. The target learners were adult L1 English speakers 18 years of age or over ...


Emotional Reverberations, Kirsten Heteji Mar 2019

Emotional Reverberations, Kirsten Heteji

Theses and Dissertations

Projecting psychological mindscapes onto domestic objects allows for an emotive and bodily connection to the domestic realm. Body, for me, is the clay and how it holds touch and softness indexically recording the actions of making in the final forms. Pushing, pulling and pinching clay evokes sensations that connect the maker’s body as well as the observer of the work to participate. I shift expectations by experimenting between the hard and softness of bodily material like clay, giving it emotional fragility in how it contrasts the original structure it imitates. I think about creating objects and the arrangement them ...


I Thought The Earth Remembered Me, Hannah Bates Jan 2019

I Thought The Earth Remembered Me, Hannah Bates

Theses and Dissertations

The forest is teeming with activity: fungi transform dead logs into nutrients, roots entangle themselves with the earth, and strong winds break resilient boughs. Like the forest, the human body functions according to a complex system of agents - from the micro bacteria in the gut to the pores of the skin. The built world has often been rendered in opposition to these processes of nature. As a vessel through which the world is experienced, the body is an intermediary between raw matter and fabricated things. The planet is suffused with human life, and there is a critical tension between human ...


Graphic Content Warning; Personal And Political Traumas, Emily K. Wardell Jan 2019

Graphic Content Warning; Personal And Political Traumas, Emily K. Wardell

Theses and Dissertations

The written portion of this thesis work is meant to address and further investigate the visual work created using mediums of print and found video. This artistic research has been interested in examining varying associations with truth, recollection, and evidence. This includes the recollection of public histories and news-media narratives as well as my own history and trauma. Through this work my aim was to create a deconstruction and revolt against how associations are formed, and how to understand imagery as information. This thesis first discusses my relationship to appropriated imagery, then connects and examines it through the addition of ...


A Graph Theoretical Analysis Of Functional Brain Networks Related To Memory And Healthy Aging, Ty Alvin Bodily Aug 2018

A Graph Theoretical Analysis Of Functional Brain Networks Related To Memory And Healthy Aging, Ty Alvin Bodily

Theses and Dissertations

The cognitive decline associated with healthy aging begins in early adulthood and is important to understand as a precursor of and relative to mild cognitive impairment and Alzheimer disease. Anatomical atrophy, functional compensation, and network reorganization have been observed in populations of older adults. In the current study, we examine functional network correlates of memory performance on the Wechsler Memory Scale IV and the Mnemonic Discrimination Task (MST). We report a lack of association between global graph theory metrics and age or memory performance. In addition, we observed a positive association between lure discrimination scores from the MST and right ...


Is Episodic Future Thinking Important For Instrumental Activities Of Daily Living In Neurological Patients?, Amanda M. Brunette Aug 2018

Is Episodic Future Thinking Important For Instrumental Activities Of Daily Living In Neurological Patients?, Amanda M. Brunette

Theses and Dissertations

Episodic future thinking is defined as the ability to mentally project oneself into the future into a specific time and place. Episodic future thinking has been explored extensively in neuroscience. However, it has not been determined whether the measurement of episodic future thinking might be valuable in a clinical neuropsychological setting. The current study examined the relationship between episodic future thinking and instrumental activities of daily living (IADLs), which is a domain of adaptive functioning frequently assessed by neuropsychologists to examine independent living potential including the ability to handle finances, prepare food, complete household duties, and manage medications. A secondary ...


The Basovizza Monument: Rebranding Public Memory, Constructing Identity, And Normalizing Political Agenda, Louise Zamparutti May 2018

The Basovizza Monument: Rebranding Public Memory, Constructing Identity, And Normalizing Political Agenda, Louise Zamparutti

Theses and Dissertations

In the early 1990s, Italy’s former Fascist party, the newly renamed Alleanza Nazionale (AN), began to promote a new interpretation of events that occurred in the final stages of World War II. In collaboration with local and national civic organizations, the AN promoted this rendition of history by publishing fictionalized memoirs and popular narratives, producing a nationally aired television drama, and finalizing the construction of a new national monument. The Basovizza Monument was officially inaugurated on February 10, 2007, and is now a popular attraction for tourists and classroom visits. This monument is the subject of my case study ...


Co-Speech Gesture Integration In Hippocampal Amnesia, Sharice Clough May 2018

Co-Speech Gesture Integration In Hippocampal Amnesia, Sharice Clough

Theses and Dissertations

Co-speech gesture is ubiquitous in everyday conversation, facilitating comprehension, learning, and memory. Information is often provided uniquely in the gesture modality and this information is integrated with speech, affecting the listener’s comprehension and memory of a message. Despite the robust evidence that gesture supports learning, the memory mechanisms that support this learning are unclear. The current study investigates the ability of patients with hippocampal damage to integrate and retain information from co-speech gesture.

Four patients with bilateral hippocampal lesions, four patients with damage to the ventral medial prefrontal cortex, and 17 healthy comparisons watched videos of a storyteller narrating ...


Beneficial Contribution Of Health Behaviors To Learning And Related Brain Mechanisms In Older Adults, Rachel Amelia Clark Cole May 2018

Beneficial Contribution Of Health Behaviors To Learning And Related Brain Mechanisms In Older Adults, Rachel Amelia Clark Cole

Theses and Dissertations

Aging is associated with adverse structural and functional changes in the brain. These changes have been directly linked to declines in certain types of learning and memory, likely due to the negative impact of aging on the hippocampus, a region necessary for cognitive functions such as relational learning, memory, and spatial navigation. Health behaviors and characteristics, like exercise and cardiorespiratory fitness (CRF), are related to better brain and cognitive aging, though more research is needed to better understand which age-sensitive aspects of cognitive function are most benefited by these health characteristics. The purpose of this collection of studies was to ...


Exploring The Resting State Neural Activity Of Monolinguals And Late And Early Bilinguals, Carrie Elizabeth Gold Jan 2018

Exploring The Resting State Neural Activity Of Monolinguals And Late And Early Bilinguals, Carrie Elizabeth Gold

Theses and Dissertations

Individuals who speak more than one language have been found to enjoy a number of benefits not directly associated with the use of the languages themselves. One of these benefits is that bilingual individuals appear to develop symptoms of dementia 4-5 years later than comparable individuals who speak just one language. Studies on this topic, however, do not consistently account for factors including if the individual learned their second language as a child or later in life, or their language proficiency. In an attempt to more carefully examine these variables, this study looks at structural and resting-state functional MRI scans ...


Of Cannonades And Battle Cries: Aurality, The Battle Of The Alamo, And Memory, Michelle E. Herbelin Jan 2018

Of Cannonades And Battle Cries: Aurality, The Battle Of The Alamo, And Memory, Michelle E. Herbelin

Theses and Dissertations

This thesis takes a sensory-historical approach to the 1836 Siege and Battle of the Alamo, its inscription into history and its propagation as a touchstone of Texas’ memory and identity. My focus is on the auditory, an especially important sensory experience to consider. Among the many auditory tactics deployed during the siege, the storming itself took place in the pre-dawn darkness, and many of the survivors’ accounts were from women and children among the garrison, who were sequestered away from the visual experience of the battle. Flooding from the accounts of survivors into the popular imagination of Texans, the sounds ...


Re-Evaluating “Authenticity” In Holocaust Literature – Memory And Trauma In Recent Holocaust Fiction, Christos Giantsidis Jan 2018

Re-Evaluating “Authenticity” In Holocaust Literature – Memory And Trauma In Recent Holocaust Fiction, Christos Giantsidis

Theses and Dissertations

This thesis provides a structural and para-textual analysis of recent Holocaust fiction. Challenging the assumption of the superiority of “authentic” representations of the psychological effects of this historic event, I will highlight the cultural and pedagogical effects of fictionalized accounts of the Holocaust. A short analysis of the terms “memory,” “trauma,” and “history” as understood in the research field of Holocaust studies, will be substantial in debunking the failures of memory as perfect ways to recreate historical “truths.” Theories about trauma and memory by scholars such as Cathy Caruth and Dominick LaCapra will serve as reference points in the validation ...


Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins Dec 2017

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 ...


People Change: Impression Management Influences Autobiographical Memories, Holly Elizabeth Cole Aug 2017

People Change: Impression Management Influences Autobiographical Memories, Holly Elizabeth Cole

Theses and Dissertations

This paper presents the results of an experiment that tested a new impression management strategy, termed memory enhancement, and the long-term implications of using memory enhancement. People often share the events that occur in their everyday lives to others in the form of stories. This research was designed to determine if people will alter the way they share previous events to create a specific impression. It is possible that using the impression management strategy of memory enhancement will create long lasting changes to the actual memory of the event. This was tested in an experiment in which participants were put ...


The Fractured Memory Of A Mind’S Eye, Russell G. White Jan 2017

The Fractured Memory Of A Mind’S Eye, Russell G. White

Theses and Dissertations

The work I create is informed by questioning reality/identity, the fractalizing planes

of existence our essence occupies, and the artifacts of memory experience navigating

through space time. While existing in this realm of oversaturated media and neon

glow, I question the effects of pervasive data systems overloading or programming the

mental software we possess. My work includes humor as a means of exploring these

conventions while also displaying psychedelic surrealist imagery to help break away

from the conscious prison this existence births our concept apparatuses within.


Restoration, Shannon M. Slaight-Brown Jan 2017

Restoration, Shannon M. Slaight-Brown

Theses and Dissertations

The marks I make in clay have different characteristics, and the physical mark of one’s fingertips or visual record of the hand is personal and intimate. This visible activity is the evidence of my constant presence and control within each object. Its repetitive meditation produces a private relief from my persistent anxieties. This exploration for me is not only visual, but also physical. This is the start of my infatuation with the idea of pattern. It has its own discrete visual language and modes of communication; and through my research I am developing a method of intercommunication.


The Effects Of The Hiv-1 Tat Protein And Morphine On The Structure And Function Of The Hippocampal Ca1 Subfield, William D. Marks Jan 2017

The Effects Of The Hiv-1 Tat Protein And Morphine On The Structure And Function Of The Hippocampal Ca1 Subfield, William D. Marks

Theses and Dissertations

HIV is capable of causing a set of neurological diseases collectively termed the HIV Associated Neurocognitive Disorders (HAND). Worsening pathology is observed in HIV+ individuals who use opioid drugs. Memory problems are often observed in HAND, implicating HIV pathology in the hippocampus, and are also known to be exacerbated by morphine use. HIV-1 Tat was demonstrated to reduce spatial memory performance in multiple tasks, and individual subsets of CA1 interneurons were found to be selectively vulnerable to the effects of Tat, notably nNOS+/NPY- interneurons of the pyramidal layer and stratum radiatum, PV+ neurons of the pyramidal layer, and SST ...


The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore Jan 2017

The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore

Theses and Dissertations

I examined the role of memory and attention in prospective person memory. Prospective person memory involves being on the lookout for a person with the goal of completing some task (i.e., contacting the authorities) upon encountering the person. Success at prospective person memory tasks in lab and field based studies is rather low (i.e., less than 10% of people report encountering the person). In the current study the prospective person memory task involved a simulated search for a missing person. I manipulated attention to the missing person and strategic monitoring, which involves being in retrieval mode and searching ...


Intention To Deceive Alters Access To Semantic Memory, James Nye Jan 2017

Intention To Deceive Alters Access To Semantic Memory, James Nye

Theses and Dissertations

I conceptualize a theory of deception within the perspective of discourse and pragmatics while choosing to examine the decision to engage in deception within the perspective of cognitive psychology. Currently, cognitive perspectives of deception have emphasized that inhibitory control of one’s motor processes are vital because in order to respond deceptively, one must prevent honest behavior from leaking into one’s actions. Although indirect evidence for inhibition is heavily linked with deception, current empirical data connecting motoric control with deceptive responses has been difficult to observe. I propose a theoretical perspective that shifts the role of inhibitory control in ...


The Mechanisms Underlying Cocaine-Induced Overexpression Of Basic Fibroblast Growth Factor (Bfgf, Fgf2), An Effect Reversed By Extinction, Madalyn Hafenbreidel Aug 2016

The Mechanisms Underlying Cocaine-Induced Overexpression Of Basic Fibroblast Growth Factor (Bfgf, Fgf2), An Effect Reversed By Extinction, Madalyn Hafenbreidel

Theses and Dissertations

Drug addiction is characterized by compulsive drug use and chronic relapse despite negative consequences. Drug-induced structural and functional changes in the brain are thought to underlie these characteristics. One mechanism that may mediate these characteristics are growth factors, such as basic fibroblast growth factor (bFGF or FGF2), as they are necessary for cellular growth, survival, differentiation, and have roles in memory, mood, and anxiety disorders. bFGF mRNA and protein expression is increased following stimulant administration and is necessary for stimulant-induced changes in dendrites and behavioral sensitization. Moreover, addiction is maintained by cues associated with the drug, as they can can ...


Memory Mechanisms Of Hand Gesture In Communication And Learning, Caitlin Ann Hilliard Aug 2016

Memory Mechanisms Of Hand Gesture In Communication And Learning, Caitlin Ann Hilliard

Theses and Dissertations

Spontaneous co-speech hand gestures robustly affect learning and memory. Viewing or producing hand gestures during conversation facilitates the encoding, consolidation, and retention of the information in speech. Despite these effects, the cognitive and neural mechanisms supporting this relationship remains unknown. In Experiment 1, I explored the memory mechanisms supporting hand gesture by working with patients with damage to their hippocampus and thus their declarative memory system. Participants engaged in discourse tasks that disproportionately engaged the hippocampus. I found that patients gestured less overall than healthy comparisons across all tasks, suggesting that the hippocampus indeed plays a role in gesture production ...


Recognition Training For Faces Across Age Gaps, William Blake Erickson Aug 2016

Recognition Training For Faces Across Age Gaps, William Blake Erickson

Theses and Dissertations

Face recognition is a problem that has theoretical and applied value. However, the fact of facial aging is rarely addressed in research and unmentioned in the major theories of face recognition. Facial aging also has ramifications for missing persons and fugitive cases, confounding attempts by law enforcement to recover these people whose last known images are years or decades out of date. This dissertation reports three studies aimed at measuring baseline age-gap recognition ability and testing various training regimens designed to increase accuracy rates for this unique kind of recognition task.


Literature As Memorial: Challenging Histories And Reckoning With Absences Through Contemporary American Literature, Sarah Lindsay Livesay Aug 2016

Literature As Memorial: Challenging Histories And Reckoning With Absences Through Contemporary American Literature, Sarah Lindsay Livesay

Theses and Dissertations

What are the intersections between literary and memorial studies? This study interrogates that question by combining critical readings of contemporary American literature (1969-present) with national memorials. My method of reading moves between physical memorials that provide canonical representations of American historical events and textual memorials that provide literary counter-readings of the same events. These texts challenge traditional memorial-making by reframing the discourses for the ways memorials function in American culture.

The study of memorial traverses several disciplines and fields of scholarship. Within the broad field of memorial studies, this dissertation examines the concerns of physical monuments and memorials, memory and ...


Sex Differences In Cognitive Decline In Mild Cognitive Impairment And Alzheimer's Disease, Juliann Thompson Jul 2016

Sex Differences In Cognitive Decline In Mild Cognitive Impairment And Alzheimer's Disease, Juliann Thompson

Theses and Dissertations

Alzheimer's disease (AD) is the most common form of dementia and results in progressive cognitive decline, particularly in regards to memory (National Institute on Aging, 2012). Prior research has shown sex differences in brain-atrophy rates of AD patients, with women experiencing a higher rate of progression in volume reduction (Skup et al., 2011). This suggests that there may also be differences in cognitive functioning between sexes, particularly in the rate of cognitive decline with a more rapid disease progression for dementing females compared to dementing males. The current study monitored memory function longitudinally in approximately 200 total participants, 100 ...


The Archon(S) Of Wildfell Hall: Memory And The Frame Narrative In Anne Brontë’S The Tenant Of Wildfell Hall, Alyson June Fullmer Jun 2016

The Archon(S) Of Wildfell Hall: Memory And The Frame Narrative In Anne Brontë’S The Tenant Of Wildfell Hall, Alyson June Fullmer

Theses and Dissertations

In the first chapter of Anne Brontë’s The Tenant of Wildfell Hall, Gilbert Markham invites his reader to join him as he attempts to recall the past. Because Gilbert uses the journal of another to supplement his own memories, the novel's frame narrative structure becomes saturated with complex memory-based issues and problems. Thus, the complicated frame narrative provides fertile ground for exploring the novel through memory. In studying the frame narrative, scholars have typically devoted their criticism to Gilbert and how he shapes the frame. Few scholars afford the other primary narrator of the novel, Helen, any power ...


Eye Movement Effects In Simulated Object Recognition Memory Impairment, Dmitriy Kazakov May 2016

Eye Movement Effects In Simulated Object Recognition Memory Impairment, Dmitriy Kazakov

Theses and Dissertations

Malingering is the purposeful fabrication of symptoms for secondary gain. Memory problems are the most reported symptom, and object recognition tests are often used in clinical settings to evaluate these claims. Past research has shown that eye movements can indirectly index memory, in that greater viewing is directed at studied stimuli 500-750 ms after display onset. The present study evaluated eye movements as a potential method of detecting feigned memory impairment. Forty-eight participants, half simulators, studied standardized images and took a memory test. Several levels of analysis were used to detect broad trends and brief effects. Simulators performed significantly worse ...


The Hippocampus And Semantic Memory Beyond Acquisition: A Lesion Study Of Hippocampal Contributions To The Maintenance, Updating, And Use Of Remote Semantic Memory, Nathaniel Bloem Klooster May 2016

The Hippocampus And Semantic Memory Beyond Acquisition: A Lesion Study Of Hippocampal Contributions To The Maintenance, Updating, And Use Of Remote Semantic Memory, Nathaniel Bloem Klooster

Theses and Dissertations

Semantic memory includes vocabulary and word meanings, conceptual information, and general facts about the world (Tulving, 1972). According to the standard view of semantic memory in cognitive neuroscience, the hippocampus is necessary to first acquire new semantic information (Gabrieli, Cohen, & Corkin, 1988), but these representations are then consolidated in the neocortex and become independent of the hippocampus with time (McClelland, McNaughton, & O'Reilly, 1995). Remote semantic memory is considered independent of the hippocampus, and the hippocampus is not thought to play a critical role in the processing and use of such representations.

The current work challenges the notion that previously ...
