Mrs. Dalloway As A Window For Understanding Life, Kristen Venegas

English (MA) Theses

Virginia Woolf’s Mrs. Dalloway may be dismissed as fiction, and fiction consequently is dismissed as fantasy. However, the novel enables readers to practice an intellectual exercise of meta-awareness that extends beyond the pages and onto real world phenomena. Under a cognitive neuroscience perspective, Mrs. Dalloway is a literary masterpiece due to its hyper- realistic execution of the intimacies of life. Through the narrative style of free-indirect discourse, Woolf illustrates what occurs in the minds of characters as they develop their own perceptions of reality and identity, exposes the fear and inadequacies of mankind’s distress in times of chaos and disorder …

Diet And The Role It Plays In Cognition, Ryan S. Lavrisa

Honors College Theses

The Food and Agricultural Organization of the United Nations have calculated the effects of animal agriculture and factory farming to be responsible for generating 14.5-16.5% of global greenhouse gas emissions as well as using 70% of all agricultural land to sustain itself. Plant-based diets such as veganism and vegetarianism have been on the rise as many seek to find diets that mitigate the animal suffering and environmental impact for which animal agriculture is responsible. With the rise of these diets, it is important to understand the cognitive effects adhering to such diets can have on the body and mind, as …

A Transdiagnostic Examination Of Cognitive Heterogeneity In Children And Adolescents With Neurodevelopmental Disorders, Sarah Al-Saoud, Emily S. Nichols, Emma G. Duerden, Loretta Norton

Western Libraries Undergraduate Research Awards (WLURAs)

Children and adolescents with neurodevelopmental disorders (NDDs) demonstrate extensive cognitive heterogeneity that is not adequately captured by traditional diagnostic systems. Using a transdiagnostic approach, a retrospective cohort study of cognitive functioning was conducted with a large heterogenous sample (n = 1529) of children and adolescents 7 to 18 years of age with NDDs. Measures of short-term memory, verbal ability, and reasoning were administered to participants with attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), comorbid ADHD/ASD, and typically developing (TD) participants using a 12-item web-based neurocognitive testing battery. Unsupervised machine learning techniques were implemented to create a self-organizing map (SOM), …

Sex Differences In Stress Reactivity, Brain Morphology, And Oxytocin In The Hypothalamus Of The Gray Short-Tailed Opossum (Monodelphis Domestica), Esperanza I. Zacarias, Daniela Rodriguez, Alexandra Chalons, Sasawan Heingraj, Nicole Altamirano, Joseph Rafac, John L. Vandeberg, Mario Gil

Research Colloquium

Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

Does The Apoe-Ε4 Allele Differentially Influence Cognition: A Longitudinal Investigation In Healthy Older Adults At Risk For Alzheimer’S Disease, Aditya Kulkarni

Dissertations, Theses, and Capstone Projects

Background: The apolipoprotein E (APOE) ε4 allele is the strongest susceptibility factor for sporadic, late-onset, Alzheimer’s disease (AD). However, not all persons who carry the ε4 allele show significant cognitive decline, and thus do not progress to dementia. The impact of the ε4 allele on memory decline has been documented primarily in populations already demonstrating cognitive impairment (i.e., those with mild cognitive impairment or dementia), with fewer investigations completed in baseline healthy older adults. Investigations of the ε4 allele and its influence on non-memory domains are also sparse in the literature. Furthermore, these cognitive investigations are typically cross-sectional and …

Oral Contraception And Cognition, Kathleen Gerencer

Electronic Theses and Dissertations

Oral contraception is currently used by over 100 million women worldwide. Women utilize contraception not only to prevent pregnancy but also to manage a wide range of health concerns, such as acne and polycystic ovarian syndrome. Although this medication has granted women bodily autonomy, helped them attain higher levels of education, and helped them enter the workforce in greater numbers, little is known about the consequences outside of the intended contraceptive effects, specifically the cognitive and behavioral consequences. Moreover, because doctors can prescribe contraception after the first menstrual cycle and during puberty, it’s possible that this critical window of development …

The Effects Of Music Therapy On Elderly Adults With Dementia, Jeante J. Jackson

Dissertations, Theses, and Capstone Projects

As people age, the brain is more susceptible to changes that diminish cognitive function. In recent years neuroscience has found convergent evidence between music therapy and brain architecture, as it has shown the generation of new connections in the brain or a reorganization and possible strengthening of existing connections already in the brain. However, the literature regarding music training’s effects on executive control, selective attention, and speech processing is lacking particularly when it comes to older populations.

This study investigated Verbal Working Memory, Visuospatial Attention and Task Initiation, and Auditory Selective Attention in a 91-year-old adult (B.P.) diagnosed with dementia. …

Plant Sentience: A Hypothesis Based On Shaky Premises, Carel Ten Cate

Animal Sentience

Plants may produce fascinating behavioural phenomena for which the label ‘cognitive process’ may be applicable, at least by some definitions. Segundo-Ortin & Calvo (2023) base their hypothesis that plants might be sentient on the premise of demonstrated presence of cognitive complexity. However, the way phenomena are ascribed, and how the term ‘cognitive’ is used by Segundo-Ortin & Calvo, deviates from the common practice in studies of animal cognition, implying greater complexity than seems justified. It thus provides a questionable basis for attributing sentience to plants.

Plant Sentience: "Feeling" Or Biological Automatism?, Andrea Mastinu

Animal Sentience

Sentience refers to the ability of an organism to have subjective experiences such as sensations, emotions and awareness. Whereas some animals, including humans, are widely recognized as sentient, the question of whether plants are sentient is still debated among scientists, philosophers, and ethicists. Over the past 20 years, many scientists such as Trewavas, Baluška, Mancuso, Gagliano, and Calvo have reported interesting discussions about memory, behavior, communication, and intelligence in plants. However, the reported conclusions have not convinced the entire scientific community. In this commentary, I would like to focus on two critical aspects related to sentience: cognition and emotion

What Will Happen If Science Will Develop A Theory Of Consciousness? Negative Ramifications., Sam S.. Rakover

Journal of Conscious Evolution

For a long time, philosophers and scientists have attempted without success to develop a mind-body theory, a consciousness theory (T_c) to explain the exact relation between the mind and the body, a solution which is based on an assumed connection between consciousness and the activity of the neurophysiological processes in the brain. An important concern of the present paper, then, is to address the question of why, despite the great research effort on the subject, no successful T_c has ever been developed. In response, McGinn (1989) proposes that the human being’s cognitive system is not equipped to …

The Influence Of Early Childhood Parental Feeding Behaviors On Self-Regulation & Food Decision-Making In Young Adults, Natasha Singareddy

CMC Senior Theses

This study used data from a diverse set of undergraduates from the Claremont Colleges to examine the relationship between cognitive control (impulsivity and response inhibition) and self-regulatory ability as an indicator of sustained early childhood parental feeding behaviors in adulthood. In addition, the current study explored if early childhood parental feeding behaviors predicted food decision-making in adulthood as a result of perceived taste and nutritional value of food items. It was hypothesized that heightened impulsivity and impaired response inhibition as measures of cognitive control would correlate to poorer self-regulation, in turn reflecting a particular mode of early childhood parental feeding …

Predictive Factors Of Bullshit Receptivity Among Adults, Gregory Coffing

Walden Dissertations and Doctoral Studies

Bullshit receptivity is a relatively new concept in the field of psychology and refers to people’s susceptibility to providing meaning to meaningless claims. Ascribing meaning to meaningless claims is a way to make inaccurate judgments regarding the behaviors, events, and interactions around each person. The research on bullshit receptivity is scant. The purpose of this quantitative cross-sectional survey design study was to investigate whether critical thinking, individualism–collectivism, political ideology, religiosity, right-wing authoritarianism, social–dominance orientation, and need for closure predict bullshit receptivity. These variables were selected to represent a greater conglomeration of daily internal and external factors that affect a person’s …

The Roles Of Media Multitasking And Technology Use In Selective Attention And Task Switching, Katina Chris

Honors Undergraduate Theses

A number of studies have explored the impact of multitasking on specific cognitive skills, primarily with regard to non-media multitasking activities. While briefly addressing technology, its use in the modern era regarding media multitasking and its associated cognitive declines has not been extensively examined. Forty-nine participants were required to complete a series of cognitive tasks including the Stroop Color and Word Test and the Trail Making Test. Data were also collected for how often participants media multitask, the amount of technology they use, as well as other demographic variables. The goal of this study was to empirically examine the role …

The Effects Of Virtual Reality-Based Mindfulness Meditation On Cognition, Rafael Leite

Honors Undergraduate Theses

Due to relatively recent strides made in the field of virtual reality, the technology's potential use in a clinical setting has been the focus of a growing body of research. Multiple studies focus on benefits of its combination with meditation interventions; however, few explore its impact following a short-term period of utilizing both. This investigation aims to explore that gap in the literature by determining whether an improvement on mindfulness and working memory test scores would be seen following a single session of virtual reality meditation. That was done by randomly assigning participants to one of two conditions. One group …

Impacts Of The Covid-19 Pandemic On College Student Brain Health, Asia Alegre

Honors Undergraduate Theses

The intent of this study was to investigate the impact of the COVID-19 pandemic on the well-being and subjective cognition in college students. The purpose of this study as well was to investigate if those who had tested positive for COVID-19 in the past had lower levels of subjective cognitive health and if students who were affected more during the pandemic experienced more disruptions to their wellbeing. Participants (N = 105) were recruited online via the Prolific platform and took part in an online survey administered on Qualtrics. A correlational analysis was performed to examine the effects of the pandemic, …

The Relationship Between Adhd-Specific Cognitive Distortions And Adult Adhd After Accounting For Clinical Syndromes And Personality Pathology, Carly Gerbi

PCOM Psychology Dissertations

Adults with attention-deficit/hyperactivity disorder (ADHD) experience many difficulties in daily functioning. It is theorized that some of the difficulties experienced by adults with ADHD result from cognitive distortions. Although previous studies have identified a preliminary relationship between cognitive distortions and ADHD, which may be accounted for by comorbid disorders; these studies did not measure ADHD-specific cognitive distortions after accounting for these comorbidities. The purpose of the current study was to assess the relationship between the frequency of ADHD-specific cognitive distortions, operationalized as ADHD Cognition Scale (ACS) and the severity of adult ADHD, operationalized as the Brown Executive Function/Attention Scale (BEF/A), …

Predictive Abilities Of Neuropsychological Measures On Functional Outcomes In The Mild Cognitive Impairment (Mci) And Dementia Populations, Morgan Bare

PCOM Psychology Dissertations

During the aging process, a decline in ability to perform everyday tasks is commonly observed. This is increasingly so for those with dementia and is a diagnostic requirement. These daily tasks require certain cognitive skills which can be measured by various neuropsychological measures. The purpose of this study is to examine which neuropsychological measures are able to detect various deficits in self-reported activities of daily living (ADL) and instrumental activities of daily living (IADL) in individuals with mild cognitive impairment (MCI) and dementia. It is hypothesized that Trail Making Test– B (TMT-B) would be the most sensitive predictor in functional …

Explicit Rule Learning: A Cognitive Tutorial Method To Train Users Of Artificial Intelligence/Machine Learning Systems, Anne Linja

Dissertations, Master's Theses and Master's Reports

Today’s intelligent software systems, such as Artificial Intelligence/Machine Learning systems, are sophisticated, complicated, sometimes complex systems. In order to effectively interact with these systems, novice users need to have a certain level of understanding. An awareness of a system’s underlying principles, rationale, logic, and goals can enhance the synergistic human-machine interaction. It also benefits the user to know when they can trust the systems’ output, and to discern boundary conditions that might change the output. The purpose of this research is to empirically test the viability of a Cognitive Tutorial approach, called Explicit Rule Learning. Several approaches have been used …

Time Is Money: Using Delay Discounting And Reflection To Improve Decision-Making In The Iowa Gambling Task, Soha Munir

Undergraduate Honors Theses

Gambling disorder is described as a persistent and reoccurring behavior that leads to distress and significant impairments in relationships, jobs, or career opportunities in the DSM V (American Psychiatric Association, 2013). With gambling behaviors on the rise, it is crucial to understand what makes one individual more likely than another to develop a gambling disorder. Impaired decision-making has been associated with problematic gambling behaviors, and delay discounting has been related to multiple behaviors such as alcohol use, drug use, and gambling. This study investigates the relationship between delay discounting and performance on the Iowa Gambling Task (IGT), a commonly used …

"I Just Want To Be Me, Authentically": Identity Shifting Among Racially And Ethnically Diverse Young Adults, Aerika Brittian Loyd, Dulce Wilkinson Westberg, Lenisha Williams, Marisha Humphries, Alan Meca, Julie Carmen Rodil

Psychology Faculty Publications

Identity shifting represents a common but complex social, behavioral, and cognitive phenomenon. However, some forms of identity shifting originate in response to structural, institutional, and interpersonal marginalization enacted on lower status groups, such as people of color in the United States. The current study investigated ways young adults from diverse ethnic/racial groups discussed shifting to fit in with White Americans (a dominant group) in the United States and their own ethnic/racial group (a minoritized group) and elucidated self-reported motivations for shifting. Participants consisted of 764 young adults (ages = 18–23) recruited from two large public universities in the Southeast and …

The Effect Of Acute Exercise On Objectively Measured Sleep And Cognition In Older Adults, Kelsey R. Sewell, Nathan D. W. Smith, Stephanie R. Rainey-Smith, Jeremiah Peiffer, Hamid R. Sohrabi, Kirk I. Erickson, Belinda M. Brown

Research outputs 2022 to 2026

Background: Exercise can improve cognition in aging, however it is unclear how exercise influences cognition, and sleep may partially explain this association. The current study aimed to investigate whether objectively measured sleep mediates the effect of an acute exercise intervention on cognition in older adults. Methods: Participants were 30 cognitively unimpaired, physically active older adults (69.2 ± 4.3 years) with poor sleep (determined via self-report). After a triple baseline cognitive assessment to account for any natural fluctuation in cognitive performance, participants completed either a single bout of 20-minutes of high intensity exercise on a cycle ergometer, or a control condition, …

The Impact Of Alzheimer Disease On Semantic Knowledge, Maileen G. Ulep

UNLV Theses, Dissertations, Professional Papers, and Capstones

The research furthers the understanding of the impact of Alzheimer disease (AD) on cognition and the organization of semantic knowledge in the brain, which might contribute to the development of diagnostic and staging tools, and interventions to palliate cognitive deficits. The disruption of semantic knowledge in AD is well documented in the literature. Much of the existing research focuses on the general impact AD has on semantic knowledge. This study explores the impact of AD on specific domains of knowledge, chiefly, living kinds and artifacts, critical to ordinary functioning. The content, organization and structure of the investigated domains of knowledge …

The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music and language are easily distinguishable for the average listener despite sharing many structural acoustic similarities. The Speech-to-Song illusion can give rise to both musical and linguistic percepts by inducing a perceptual switch after listening to multiple repetitions of a natural spoken utterance. As such, it has been used as a tool to control for low-level acoustic characteristics previously shown to drive lateralized brain responses regardless of domain-type, helping to disambiguate the contribution of high- versus low-level processes in both music and speech perception. However, there exists a lack of research on how large a role individual differences such as …

An Evidence Review Of Behavioural Economics In The Justice Sector, Brian Barry, Lucia Morales, Aiden Carthy

Articles

Behavioural economics combines elements of economics and psychology to better understand how and why people behave the way they do in the real world. While behavioural economics originally sought to better understand economic decision-making, it has since grown in scope and application, and it is increasingly used by governments, government departments and other organisations to shape and implement public policies in a range of policy areas. This Review considers the application of behavioural economics theories and concepts (commonly referred to as behavioural insights) to the justice sector in a range of areas of justice policy in different jurisdictions. Areas of …

Cognitive Effort Avoidance In Veterans With Suicide Attempt Histories, James M. Bjork, Chelsea S. Rooney, Lisa K. Straub, David M. N. Garavito, Andrew Westbrook

Articles

Suicide attempts (SA) are increasing in the United States, especially in veterans. Discovering individual cognitive features of the subset of suicide ideators who attempt suicide is critical. Cognitive theories attribute SA to facile schema-based negative interpretations of environmental events. Over-general autobiographical memory and facile solutions in problem solving tasks in SA survivors suggest that aversion to expending cognitive effort may be a neurobehavioral marker of SA risk. In veterans receiving care for mood disorder, we compared cognitive effort discounting and evidence-gathering in a beads task between veterans with (SAHx+; n = 26) versus without (SAHx-; n = 22) a history …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia

Dissertations, Theses, and Capstone Projects

Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …

Examining The Relationships Between Socio-Cognitive Factors And Neural Synchrony During Movie Watching Across Development, Kathleen M. Lyons

Electronic Thesis and Dissertation Repository

While different cognitive abilities mature, the conscious experiences of children likely become richer and more elaborate. A challenge in investigating relationships between cognitive development and real-world experiences is having measures that assess naturalistic processing. Movie watching offers a solution, since following the plot of a film requires cognitive processes that are similar to real-world experiences. When different adults watch the same film, their brain activity begins to align (known as neural synchrony). The strength of this alignment has been shown to reflect the degree to which different individuals are having a similar experience of the movie. While this phenomenon has …

Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack

Faculty Publications

Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …
