Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna

Electronic Theses, Projects, and Dissertations

In Parkinson’s Disease (PD), research has shifted to investigate how biomarkers commonly seen in Alzheimer’s Disease (AD), such as amyloid beta (AB), may be associated with cognitive functioning in PD. AB is considered a reliable biomarker for AD pathology, however in PD there is a lacking biomarker that can accurately reflect severity of cognitive impairment. AD research has shown an association between low AB and cognitive decline, but the data in PD has mixed results. Most studies that analyze cognitive decline and biomarkers do not use a cutoff level and the few that do have a threshold vary greatly in …

The Impact Of Emotional Sounds On Arousal And Task Performance, Brian Wu

Electronic Thesis and Dissertation Repository

In times of emotional arousal, it is hypothesized that neural processes are triggered to “heighten” our senses to better respond to threatening stimuli. Some studies have tested this by exposing participants to emotional sounds to determine their impacts on visual acuity but have found mixed results. Previous studies have not investigated interactions between arousal induced by emotional sounds and visual acuity. Participants (N = 42) performed an orientation detection task while presented in silence or with sounds that varied in valence. Results displayed comparable accuracy across conditions but significantly faster response times during the presentation of negative sounds on the …

P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak

Electronic Theses and Dissertations

Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically …

The Anatomical Embodiment Of Morning Routines In The Reduction Of Anxiety: An Intervention, Natalie Wright

Expressive Therapies Capstone Theses

The topic under investigation is whether physically embodying a morning routine that was designed through the lens of Laban Bartenieff Movement Analysis (LBMA) will reduce daily symptoms of individuals diagnosed with Generalized Anxiety Disorder.

Since morning routines play a significant part in one’s preparation for the day, I created an individualized LBMA morning routine for a specific client to embody. In addition to the routine, the client documented the process of their anxiety levels on a weekly basis. This client was a white, female, 19-year-old, lesbian college student who was previously diagnosed with Generalized Anxiety Disorder (GAD). The movement analysis …

The Relationship Between Cognitive Impairment In Psychiatric Patients And Readmission Rate To An Inpatient Facility, Cherilyn Isis Schuff

Theses and Dissertations

The primary intention of this study was to further understand the impact of assessing cognitive impairment in psychiatric patients, as a mediating factor on readmission rates. Mild cognitive dysfunction impacts a patient’s functional outcomes (Bowie & Harvey, 2006; Davis et al., 2012; Marcantonio, et al., 2001). Little information exists to guide best practices in the treatment of adults with cognitive impairment who are hospitalized for acute conditions (Davis et al., 2012). A cognitive impairment may impact patient prognosis and ability to function outside of a setting focused on stabilization. Neuropsychological testing is a valuable tool in predicting a patient’s cognitive …

What Are We Most Curious About? Understanding The Relationship Between Curiosity And Marginal Knowledge, Alexis Lee

CMC Senior Theses

There are several competing theories about the relationship between curiosity and metacognitive judgment, or one’s assessment of their own knowledge. Novelty theories say that curiosity is highest for wholly unknown information; complexity theories say that curiosity is highest for moderately unknown information; and the Region of Proximal Learning (RPL) theory says that curiosity is highest for almost-known information. The present study aimed to address how curiosity differs within marginal knowledge (MK), memory content that is available but not accessible, across two experiments. In both experiments, participants responded to 100 short-answer general knowledge questions, selecting a phenomenological category to represent their …

The Standing Of Anger: Insights From The Debate(S) On Constructed Emotion, Andrew Holzer

CMC Senior Theses

In her book, Anger and Forgiveness: Resentment, Generosity, Justice, Martha Nussbaum argues that anger is inherently flawed because it fundamentally contains the desire for payback. To support her argument, she posits specific metaphysical claims about the nature of emotions like anger. This thesis is an extended critique of her metaphysical foundation from the perspective of empirical research in the neuroscience of emotion. The first reason to dispute this picture is descriptive; this view of anger is based on an outdated version of cognitive appraisal theory, which sees emotions as triggered directly by static moments of cognitive appraisal. The second …

Investigating The Role Of Glycemic Control In Cognitive Impairement Risk Among Elderly Individuals With Type 2 Diabetes: A Scoping Review, Julia Pessaia

Honors Undergraduate Theses

Type 2 diabetes mellitus (T2DM), presents a significant health burden globally, affecting millions of individuals, especially in the elderly population. While its association with cardiovascular diseases and cognitive impairments is well-documented, further research on the precise influence of glucose control on cognitive outcomes in elderly T2DM patients is necessary. This scoping review aims to address this gap by investigating the impact of HbA1c levels representing glycemic control on the risk of developing cognitive impairments in elderly patients with T2DM. A literature search was conducted on MEDLINE and eligible studies involved T2DM patients aged 60 or older, with documented cognitive function …

Neurocinematics And Empathy: How Cognitive Neuroscience Enhances Our Understanding Of Emotional Responses Of Film, Kira Trinity

Cal Poly Humboldt theses and projects

Cinema is a medium that is beloved around the globe since its inception over a century ago. There have been speculations on how it is that cinema works, from editing to emotional processing of the story, but only recently have we begun to explore the inner workings of cinematic impact on the brain. In this paper we will review research on cinematic impact and define cinematic editing, discuss the birth of “neurocinematics”, highlight what we have observed with regards to neuroimaging and empathy when viewing films, and speculate on how our responses to cinema may be driven by the Mirror …

Brainwaves, Memory, And Reward, Rebecca Mccune

Dissertations, Theses, and Capstone Projects

The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …

Fraction Magnitude Understanding Across Learning Formats: An Fmri Study, Chloe A. Henry

Electronic Thesis and Dissertation Repository

Knowledge of fraction magnitudes are an important, but notoriously difficult mathematical concept to master. Behavioural work has begun to explore and compare the instructional tools used for fraction learning. However, how fraction instructional tools are processed in the brain remains an underexplored question. Therefore, in the present thesis, we used functional brain MRI methodology to examine the neural activity of adult participants while completing a fraction verification task using the number line and area model, two common methods of fraction learning. We found that both models commonly recruited fronto-parietal activity, the neural regions typically implicated in number processing. However, we …

Voluntary Action And Conscious Intention, Jake Gavenas

Computational and Data Sciences (PhD) Dissertations

Traditional experimental methodology in neuroscience involves comparing responses to different stimuli to make inferences about the human brain. However, human volition entails making decisions and acting in a manner that is underdetermined by the external environment. Investigations of the neuronal basis of volition have led to new controversies regarding the existence of free will, and offer potential directions for medical treatments of disorders such as addiction, akinetic mutism, and locked-in syndrome. However, because volition experiments leave aspects of responses “up to” participants, neuroscientists must utilize computational techniques such as modeling, simulation, and advanced analyses to progress our understanding of human …

Destined Failure, Chengjun Pan

Masters Theses

I attempt to examine the complex structure of human communication, explaining why it is bound to fail. By reproducing experienceable phenomena, I demonstrate how they can expose communication structure and reveal the limitations of our perception and symbolization.I divide the process of communication into six stages: input, detection, symbolization, dictionary, interpretation, and output. In this thesis, I examine the flaws and challenges that arise in the first five stages. I argue that reception acts as a filter and that understanding relies on a symbolic system that is full of redundancies. Therefore, every interpretation is destined to be a deviation.

Sleep Duration Is Associated With Caudate Volume And Executive Function, Nicole Jones

Honors Theses

The ineligible role of the caudate nucleus in sleep has been implicated throughout multiple scientific studies. Previous literature has shown that greater caudate volume is associated with longer habitual sleep duration in older adults- ranging from 55 years of age and up. However, the association between sleep duration and caudate volume remains unknown in the younger population. In this study, we examined the caudate volume in youth to older adults (10 to 85 years old) with a greater sample size (N=464) to increase statistical power. The volumetric size of the caudate nucleus showed significantly positive association with habitual sleep duration, …

Does State Of Mind Predict Prototype-Based Category Learning In Older Adults?, Kana Kimura

Theses and Dissertations

Category learning plays an important role in day-to-day lives across all ages, allowing us to organize related experiences, develop expectations, and determine how we behave given those expectations. Despite its importance, the current body of literature on category learning in older adults is much smaller than that of other memory domains. Thus, little is known about how well older adults learn new concepts and what factors best promote learning novel categories. One factor that may affect category learning abilities is an individual’s state of mind. A number of studies demonstrate the effects of sleep, stress, affect, and motivation on cognition, …

Aggression In And Out Of The Surrounding Space, Marissa Incer

Undergraduate Honors Theses

Social isolation is a type of punishment used to address misbehavior in individuals, such as children with time-outs and prisoners in solitary confinement. It was thought to be an effective method for teaching good behavior or alleviating tense situations. However, this type of punishment may worsen the punished individual’s aggression depending on the environment of isolation. The current study was divided into two experiments. In the first experiment, participants were isolated in a small (2x2 feet) or large (6x6 feet) space to observe if the space alone affected their aggression. In the second experiment, a frustration-inducing task was given to …

Mapping The Malleable Self: How Self-Views Are Represented And Learned Within The Social Brain, Sasha Carmela Brietzke

Dartmouth College Ph.D Dissertations

Humans possess a unique and wide-ranging ability to self-reflect that takes center stage in our everyday cognition. While many people believe their own self to be immutable, different contexts may warp how we perceive the self. The goal of this dissertation is to investigate two lenses through which we may view the self: (1) across time in the past and future, and (2) through the eyes of others via evaluative feedback. In Studies 1-3, I demonstrate that people’s ratings of their own personality become increasingly less differentiated as they consider more distant past and future selves. This effect was preferential …

Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories of auditory and visual scene analysis suggest the perception of scenes relies on the identification and segregation of objects within it, resembling a detail-oriented processing style, but it is possible that a global-oriented process also occurs while evaluating auditory scenes. There is evidence for global properties that enable rapid recognition of visual scenes, even without recognizing the individual objects comprising the scene. It is our understanding that a similar line of research has not been explored in the auditory domain; therefore, we evaluated the contributions of high-level global and low-level acoustic information to auditory scene perception. A secondary aim …

Dietary Fatty Acids And The Brain: Mechanisms Behind Neurodegeneration And Neuroprotection, Bianca Kdeiss

Loma Linda University Electronic Theses, Dissertations & Projects

The impact of dietary fat intake on cognitive function has generated growing interest as the incidence of neurodegenerative disorders continues to increase. No known cures for neurodegenerative disorders exist at this time and available pharmacological treatments are limited in their efficacy. As such, prevention and early detection have been emphasized, particularly in the context of modifiable lifestyle factors, such as diet. Despite a recognized association between dietary fat intake and cognition, limited research exists delineating the impact of different types of fat on cognitive function. In this review, research examining the association between cognition and specific dietary fatty acids—such as …

Unexpected Arousal Suppresses Memory And Metamemory Predictions During Associative Face-Name Recognition Task, Sameer Sabharwal-Siddiqi

Dissertations, Theses, and Capstone Projects

Successful recognition often depends on probabilistic estimation of memory-signal. Arousal has been shown to offset the influence of heuristic evidence on memory prediction. We conducted three experiments that tested whether arousal also suppresses predictions relevant to memory confidence. Experiments employed associative face-name memory tasks that included retrospective (Experiments 1 and 2) or concurrent (Experiment 3) judgements of confidence. During test, subjects were presented with a masked-affective face on a subset of trials. By timing the masked-affective face to precede a recognition judgement (Experiment 1), we replicated the finding that unexpected arousal offsets the influence of heuristic evidence on expectations of …

Role Of The Default-Mode Network During Narrative Integration In Major Depressive Disorder, Darren Ri-Sheng Liang

Electronic Thesis and Dissertation Repository

How brain activity is synchronized across individuals during narrative comprehension has previously been characterized by functional magnetic resonance imaging (fMRI) in healthy and patient populations. To our knowledge, there has been limited investigation as to how it is affected by major depressive disorder (MDD). We addressed this issue with fMRI through examination of inter-subject synchronization in the default mode network (DMN), brain structures which have previously been implicated in MDD pathology. Twenty-two patients with MDD and 20 matched control participants listened to Intact versus Scrambled versions of an auditory narrative; these experimental conditions differed in the degree of temporal integration …

Temporal Dynamics Of Attention Bias In Anxiety: An Eye Tracking Study, Abel Mathew

Theses and Dissertations

Behavioral reaction time (RT) measures, like the dot-probe and spatial cueing tasks, have shown that individuals with anxiety tend to bias their attention toward threat as compared to neutral stimuli. However, the literature has revealed mixed findings due to the simplistic calculation of attention bias (AB; i.e., Mean RT Threat – Mean RT Neutral). Research has shown that attention bias fluctuation (i.e., patterns of both vigilance and avoidance), is indicative of attention dyscontrol, which is evident in those with psychopathology. As such, the purpose of this study was to evaluate whether AB fluctuation via behavioral RT measures and eye-tracking, stands …

The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills

Graduate Theses and Dissertations

Alzheimer’s disease and related dementia (ADRD) rates are expected to triple by the year 2050. Early detection and specific mitigation efforts are warranted to blunt the alarming rate. Physical function (PF) declines with age, but higher physical function is associated with better cognitive functioning in middle-to- older age individuals. Moreover, greater physical activity (PA) is associated with better global cognition; however, Apoliporotein e4 carriers may not gain the same benefits with exercise. Additionally, plasma phosphorylated tau 217 (p-tau217) has been identified as a novel diagnostic ADRD biomarker which needs further research to examine associations with risk factors. Therefore, the aims …

Withdrawal From Voluntary Oral Methamphetamine Reveals Female Specific Susceptibilities To Behavioral Deficits And Neurochemical Perpetuators Of Neurotoxicity And Drug Seeking Behavior, Nicoletta K. Memos

Dissertations, Theses, and Capstone Projects

MA is a potent, highly addictive psychomotor stimulant known to produce neurotoxic effects on the brain leading to neurological impairments^1-6 characterized by neurodegeneration of dopaminergic fibers, cell bodies and pathways, as well as brain regions such as the hippocampus, frontal cortex, and midbrain^1,5.

In MA addiction, women are more vulnerable to the behavioral and cognitive effects of MA compared to men. Adult human literature reveals gender differences in usage patterns and women demonstrate increased vulnerability to the neurotoxic effects and health effects of MA use. Women begin drug use at an earlier age, escalate drug use quicker, …

Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell

Dissertations, Theses, and Capstone Projects

Successful regulation of fear memories is a fundamental tenet to the exposure-based therapies often employed by mental health professionals for individuals with PTSD, phobias, and other anxiety disorders. Consequently, the efficacy of these treatment methodologies is largely dependent on the strength of the fear memory, as stronger memories are often characterized by an increased resistance to extinction and heightened fear recovery. However, there is little consensus within the scientific community regarding how to effectively maximize fear memory strength in human studies, and the literature exploring the impact of variability in acquisition parameters on memory strength is sparse. Here, we tested …

Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson

Honors Thesis

Neurofeedback training has been a recent field of study in neuroscience, as a potential way to increase focus, and possibly boost cognitive performance. Most studies utilize a course of neurofeedback training sessions to find positive results in decreasing ADHD symptoms, depression symptoms, as well as further cognitive changes. In this study, we aim to determine the efficacy of a single session of neurofeedback training in increasing cognitive performance. To do so, we randomly separated 42 volunteers into either a control or experimental group. The experimental group participated in an n-back task both before and after an alpha neurofeedback training session, …

Individual Differences In Structure Learning, Philip Newlin

Theses and Dissertations

Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …

Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance

Honors Theses

The progression of Alzheimer’s disease is primarily characterized by a loss of memory concerning past events, as well as a lack in ability to create new memories. While this spans across many subsets of memory, such as recognition, recall, and autobiographical memory, there seems to be a lesser impact on musical memory in those with Alzheimer’s. Multiple studies have suggested that exposure to music and introduction of music therapy can even improve other aspects of memory in Alzheimer’s patients. This systematic review and meta-analysis sought to examine the relationship between music exposure and autobiographical memory specifically. A pool of electronic …
