Cognitive-Affective And Somatic Depressive Symptom Domains Related To Psychological Mechanisms And Sociodemographic Factors, Danielle B. Hazeltine

Dissertations, Theses, and Capstone Projects

Major depressive disorder is prevalent, chronic, and heterogeneous, including cognitive- affective (e.g., maladaptive beliefs or thinking patterns and sad mood) and somatic (e.g., fatigue, appetite, or sleep changes) symptom domains. While depression domains have been long theorized, research examining psychological mechanisms underlying this distinction is limited. Preliminary research suggests cognitive-affective symptoms relate more strongly to cognitive mechanisms (cognitive bias, perseverative thought), somatic symptoms relate more strongly to behavioral mechanisms (behavioral inhibition/activation), and gender, race, and ethnicity moderate these relationships. This study examined whether cognitive-affective and somatic symptom domains differentially relate to cognitive and behavioral mechanisms, and whether these relationships are …

Hyman

Student Publications [Scholarly]

Background and Hypothesis: Schizophrenia spectrum disorders (SSDs) produce severe symptoms, disability, and premature mortality, but only partially effective symptomatic treatments exist. Treatment development is impeded by lack of insight into disease mechanisms or objective biomarkers for clinical trials. Advances in genetics and neurobiology have converged on strong pathogenic hypotheses for SSDs centered on synapse dysfunction and excessive pruning, pathogenic processes that may produce measurable proteomic evidence in cerebrospinal fluid (CSF). Leveraging design precedents from successful fluid biomarkers discovery for Alzheimer’s disease, we undertook a pilot study to test the feasibility of repeated CSF and blood samples collection from individuals with …

Behind The Self-Report: Cognitive Symptoms And Moderating Variables During Covid-19 Quarantine, Ashley H. Jo

Student Scholar Symposium Abstracts and Posters

A lesser-known impact of the SARS-CoV-2 (COVID-19) pandemic is the impairment of cognitive functioning among seemingly unsusceptible, healthy, and young populations. Research suggests that the circumstances of extreme social isolation, incited by the pandemic, have had significantly negative effects across various social, cognitive, and psychological dimensions, with a specific focus on adolescents who are at a unique and more extreme risk than adults and children. By applying the cognitive load theory (CLT) to the COVID-19 quarantine landscape, this study measured the effects of the COVID-19 quarantine on cognitive functioning among those who were adolescents and young adults at the time …

A Longitudinal Study On The Impact Of Childhood Air Pollution Exposure On Adolescent Cognition, Emily K. Carter

Open Access Dissertations

About 2 in 5 Americans live in areas with unhealthy levels of air pollution. Poor air quality has been shown to lead to a diverse set of negative health that can affect the cardiovascular system and have downstream effects on brain structure and cognition. The detrimental impacts of air pollution on cognition have been widely studied, though due to methodological limitations in the available research, a direct association between air pollution exposure and cognitive development remains inconclusive and unclear. Further, studies in this area have largely focused on prenatal exposure and neurocognitive impacts during early childhood; the potential longer-term effects …

Reconnecting The Body With Nature: Inspired By Advances In Biomimicry, Elyse M. Orosa

Williams Honors College, Honors Research Projects

Reconnecting the Body with Nature: Inspired by Advances in Biomimicry will visually address the symbiotic relationship between nature and humans. The drawing series is inspired by the growing design field of biomimicry and its technological and architectural innovations influenced by nature’s systems and physical adaptations. Just as nature is limited by human misuse, humans are physically and neurologically limited by the state of the environment, and with this, form and function of both nature and humans will be equally represented and explored throughout the body of work presented. Biomimicry can help solve environmental issues such as rising CO2 emissions and …

Just A Slip: Cognitive Distortions Associated With Lapse And Relapse In Recovery, Matthew Karr

PCOM Psychology Dissertations

Substance use rates in the United States continue to rise despite low treatment utilization. Research has indicated the function of distorted patterns of thinking that can influence the relapse process. This study aimed to examine the relationships between relapse patterns, length of abstinence, and endorsed rates of cognitive distortions on the Cognitive Distortions Scale (CDS). This study sought participants 18 years or older with a history of problematic substance use and substance use treatment within the past 2 years. Participants were recruited through social media sites. Proposed statistical analyses included Pearson’s product-moment correlation, analysis of variance (ANOVA), and multivariate analysis …

Increasing The Efficiency Of Screening For Severity Level Of Neurocognitive Impairment In The Corrections Sample: An Exploratory Study, Kelly Denton

PCOM Psychology Dissertations

Acquired brain injury (ABI) is a serious and potentially devastating health condition that can cause several lasting deleterious consequences affecting many domains of life. Difficulties are commonly reported in cognition, emotional, and social functioning, in addition to physical impairment. ABI disproportionally affects different groups, including the corrections population, which is five times more likely than the general population to have an ABI. However, there is limited research on the severity of neurocognitive impairment after an ABI for inmates in a correctional setting. It was hoped that the current study would help clarify the characteristics of ABI that result in different …

Next-Day Effects Of Binge Drinking On Inhibitory Control In Laboratory And Naturalistic Settings, Justin Verlinden

Theses and Dissertations--Psychology

Binge drinking occurs at an alarmingly high rate, despite its negative consequences on behavior, health, and cognition. One acute cognitive consequence of binge drinking is the impairment of inhibitory control, or the ability to stop oneself from engaging in maladaptive or inappropriate behaviors. Specifically, during a binge episode, individuals display impaired inhibitory control while completing Go/NoGo or Stop Signal Tasks (SST). This impairment has been shown to be maintained for up to five hours post-drinking, even as breath alcohol concentration (BrAC) approaches zero. Evidence also suggests that binge drinking results in next-day deficits in attention, memory, and psychomotor speed. However, …

An Insidious Interstice: Understanding Cognition And Language Behaviour Through The Eyes Of Juvenile Justice Professionals, Anne M. Perrotti, Allison T. Chappell, Tancy Vandecar-Burdin

Human Movement Studies & Special Education Faculty Publications

Introduction

Despite evidence suggesting language and cognition deficits are prevalent for justice involved youth, little research explores how juvenile justice personnel experience language and cognition behaviours in the youth they serve.

Aims

This qualitative study explored how juvenile justice personnel understand language and cognition skills and deficits in justice involved youth.

Methods

Twenty-two U.S. juvenile justice professionals participated in individual, semi-structured interviews. Questions focused on individual understanding of receptive language, expressive language, social communication, and cognition (i.e., problem-solving, predicting consequences and impulsiveness) in juveniles served. Using a phenomenological lens, transcripts were coded identifying themes and sub-themes of participant responses.

Susceptibility To High-Fidelity Misinformation: An Eye-Tracking Analysis, Yasasi Abeysinghe, Gavindya Jayawardena, Enkelejda Kasneci, Sampath Jayarathna

Computer Science Faculty Publications

With the rise of online misinformation and AI-generated text, understanding human perception of news truthfulness is critical. In this study, we examine visual attention and cognitive processing using eye-tracking measures as individuals read fake and real news articles sharing nearly identical structure and imagery, differing only in subtle textual changes. Using the public FakeNewsPerception dataset, we analyze advanced gaze measures, including scanpaths, AOI transitions, and luminance-corrected pupil measures, beyond basic gaze features, in relation to news truthfulness and perceived believability. Results show that, given the high fidelity of the fake news, readers exhibited comparable visual scanning patterns, attention allocation across …

Does Memory Trust Predict Confidence In Memory Performance?, Rachel Thayer, Jenna Thomason

2024 Symposium

Generally, people tend to believe that they are poor at remembering vital information while simultaneously displaying a tendency to overestimate their performance on memory tests. People display the usage of their metamemory, the control and awareness of memory, by monitoring and reporting how much information they have accurately remembered. Predicting the outcome of test scores is one way of testing metamemory, but this does not address how a person’s trust in their memory relates to their perceptions of how they performed on a test. The Squire Subjective Memory Questionnaire (SSMQ) measures beliefs about susceptibility to omission errors (excluding information), and …

Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Traumatic brain injury (TBI) can contribute to changes in cognitive and emotional functioning, quality of life, and psychosocial reintegration. Chronic pain is a common consequence of TBI which can uniquely impact such outcomes. Still, the exact nature of the contribution of pain on post-TBI outcomes remains unclear, and there are few existing studies exploring the treatment journey for chronic pain and injury rehabilitation through qualitative methods, specifically individual interviews with TBI survivors. This study aimed to document these narratives and to identify precisely how the experiences of TBI survivors seeking treatments, rather than the treatments themselves, impact outcomes. It also …

"That Movie Changed Me!" Effect Of Induced Mood On Story Interpretation, Rachel Deborah Thayer

2025 Symposium

Studies have found that mood can affect a variety of aspects of cognition, such as memory, comprehension, and decision making. In one such study, participants identified with the character that reflected their hypnotically induced mood, and in another, story endings that were incongruent with the film clip-induced mood were more difficult to process. In the current study, film clips were used to induce moods, and participants were asked to write an ending to an ambiguous story. The prediction is that participants’ completions will reflect their induced mood. To date, 25 Eastern Washington University undergraduate students have been recruited and screened …

Low Premorbid Iq May Exacerbate The Cognitive Effects Of Apolipoprotein Ε4 (Apoe Ε4): A Multi-Ethnic Cross-Sectional Study From Habs-Hd, Lubnaa B. Abdullah, Zhengyang Zhou, Ney Alex Alliey, Robert Barber, James Hall, Sid O’Bryant

Psychological Science Faculty Publications

Introduction: Apolipoprotein allele 4 (APOE ε4) is associated with lower IQ scores during childhood and adolescence, but the influence of APOE ε4 and low IQ on late-life cognition is unknown. This study examines the association between APOE ε4 and cognitive outcomes based on premorbid intellectual ability (pIQ) and ethnic background.

Methods: Participants were drawn from the Health & Aging Brain Study–Health Disparities (HABS-HD), categorized by low (z ≤ −2.00) or average (z = 0.00 ± 1.00) pIQ based on word reading scores. Statistical analyses were conducted to evaluate whether APOE ε4 was associated with the cognitive domains of …

A Multidimensional Preclinical Investigation Of The Biogenic Amine Depletion And Subchronic Swim Models Of Fibromyalgia, Cassie M. Argenbright, Ian F. Scully, Damaris Flores, Perry N. Fuchs

Psychological Science Faculty Publications

Pain is a multidimensional phenomenon, encompassing affective-motivational, cognitive-evaluative, and sensory-discriminative domains. Understanding these components is crucial for effective diagnosis and management, particularly in conditions like fibromyalgia (FM), where pain is of unknown etiology. However, attempts to replicate FM through preclinical models often fail to replicate the disorder’s multidimensionality. These studies evaluated the multidimensionality of two primary preclinical FM models—biogenic amine depletion(reserpine) and subchronic swim stress—across all three pain dimensions, and these models assessed predictive validity using the FDA-approved pharmacologic duloxetine (Cymbalta®). Additionally, the combinations of these models assessed whether their integration better mirrors clinical manifestations. The biogenic amine depletion model …

Olfactory Training: Reclaiming Our Wellbeing, Nathan Smetzer

Doctoral Dissertations and Projects

The connection between the sense of smell and memory offers a promising avenue for enhancing cognitive, emotional, and mental health, thereby contributing to overall wellbeing. This research explores how olfactory stimuli relate to memory and emotion, aiming to expand understanding of the effects of scent-based interventions on mental health. Utilizing a 12-week longitudinal phenomenological approach with experimental components, the study engaged seven participants in a regimen of olfactory training twice daily. Participants used essential oils—citrus, cloves, eucalyptus, and rose—applied to cotton and kept in sealed containers, along with a pen and daily planner. Data were gathered through recurring qualitative interviews …

The Positivity Effect In Contracts, Megan Kathryn Stricker

College of Science and Health Theses and Dissertations

The positivity effect is a noted preference for positive information over negative information in older adults’ cognition. This effect has been observed in multiple domains of cognition, including both attention and memory (Carstensen & Mikels, 2005). Evidence for the positivity effect has shown up consistently in replications across type of memory (Reed et al., 2014), and this phenomenon can be considered within the context of other trends of cognitive aging. Most if not all research in this area has been constrained to laboratory settings, and there has been limited research as to the context sensitivity of this observed effect. What …

Does Schooling Improve Cognitive Abilities At Older Ages? Causal Evidence From Nonparametric Bounds, Vikesh Amin, Jere R. Behrman, Jason M. Fletcher, Carlos A. Flores, Alfonso Flores-Lagunes, Hans-Peter Kohler

Upjohn Institute Working Papers

We revisit much-investigated relationships between schooling and health, focusing on schooling impacts on cognitive abilities at older ages using the Harmonized Cognition Assessment Protocol in the Health & Retirement Study (HRS) and a bounding approach that requires relatively weak assumptions. Our estimated upper bounds on the population average effects indicate potentially large causal effects of increasing schooling from primary to secondary; yet, these upper bounds are smaller than many estimates from the literature on causal schooling impacts on cognition using compulsory-schooling laws. We also cannot rule out small and null effects at this margin. We do, however, find evidence for …

Arts-Based Sustainability: From New York To Malawi, Martha B. Lerski

Publications and Research

Recognizing that libraries serve multiple constituencies and subject areas, this chapter documents and advocates for development of transdisciplinary arts-based research (ABR) and culture-related projects linked to environmental challenges. Libraries contribute collections and spaces, as well as the research of library and information scientists. Libraries are currently among invisible contributors to sustainability planning and services. The chapter will link this invisibility to the value of what visual arts refer to as negative space elements in subjects ranging from traditional ecological knowledge to environmental science. Library collections, projects, and research contribute to education for sustainable development (ESD) as required to achieve the …

Waffles And Spaghetti: The Effects Of Cognitive Processing Methods On Team Performance And Communication, Jonah Daniel Browning

Masters Theses

The goal of this thesis is to shed light on a practical method for resolving conflicts in team environments that stem from miscommunications brought on by differing cognitive processes. Our brains use different cognitive processing techniques to make sense of and explore the vast amount of information the world presents them on a daily, even hourly basis. Each person has their own thinking style which influences how teams collaborate and problem solve. However, miscommunication can often arise when individuals fail to recognize and adapt to the varying processing methods, which can lead to frustration and inefficiency.

This research seeks to …

Comparing Gains And Losses: Examining The Effects Of Incentives On Working Memory Capacity And Motivational Processes In Older Adults, Julie Q. Pham

Psychology Theses and Dissertations

Working memory is critical for the storage and maintenance of information but is susceptible to age-related changes. Prior studies have shown that incentives can be used to successfully modulate cognition in older age. However, research has largely focused on the use of reward incentives. Less is understood about the motivational processes of avoiding losses and whether this can also improve working memory capacity. Given that an aversion to losses may become more salient with age, it is important to determine whether these motivational shifts are reflected in how older adults attend to and store information. The current study compared how …

Pulse Pressure, White Matter Hyperintensities, And Cognition: Mediating Effects Across The Adult Lifespan, Jade Hannan, Sarah Newman-Norlund, Natalie Busby, Sarah C. Wilson, Roger Newman-Norlund, Chris Rorden, Julius Fridriksson Ph.D., Leonardo Bonilha

Faculty Publications

Objectives: To investigate whether pulse pressure or mean arterial pressure mediates the relationship between age and white matter hyperintensity load and to examine the mediating effect of white matter hyperintensities on cognition.

Methods: Demographic information, blood pressure, current medication lists, and Montreal Cognitive Assessment scores for231 stroke- and dementia-free adults were retrospectively obtained from the Aging Brain Cohort study. Total WMH load was determined from T2-FLAIR magnetic resonance scans using the TrUE-Net deep learning tool for white matter segmentation. In separate models, we used mediation analysis to assess whether pulse pressure or MAP mediates the relationship between age and total …

Does An Impaired Sense Of Smell Make It Harder To Think About Things Like Garlic?, Ishrat N. Khan

Honors Scholar Theses

According to sensorimotor-based (also called "embodied" or "grounded") theories of semantic memory, accessing conceptual knowledge about things involves reactivating—or “simulating”—the sensory and motor experiences that we have had with them. For instance, thinking about things for which olfactory experience is dominant (e.g., garlic or a rose) would involve simulating their smell. However, evidence for olfactory simulation when thinking about "smelly” things is sparse and mixed. We tested smell-impaired (“anosmic”) and control participants (N=130 in the anosmic group and N=190 in the control group) on three tasks (1) Picture-Word Verification, (2) Semantic Property Verification, and (3) Free Recall. We predicted that …

Cognitive Advantages Of Dual Language: Bilingualism And Its Relationship With Working Memory And Controlled Attention, Ellison Alexander

Honors College Theses

This study investigates language familiarity and executive function within individuals who are fluent in or actively learning a second language, demonstrating whether bilingualism influences working memory performance and controlled attention. The study population consisted of undergraduate students attending Murray State University. Three groups were evaluated: students with a low-experience level in a second language (100 level classes), a high-experience group (200 level classes and beyond), and a separate control group of monolingual students without college-level language experience. All groups completed assessments of working memory performance and controlled attention by engaging in the Symmetry Span task and the Simon task. In …

Penny For Your Thoughts: Exploring Mechanisms Linking Socioeconomic Status And Cognition, Colton Hunter

Graduate Theses and Dissertations

Socioeconomic status is a complex psychological construct linked to a number of professional and personal barriers, including cognitive deficits. Throughout this dissertation, I seek to examine the mechanisms that link socioeconomic status and cognition. First, I explore potential mediators in the link between adolescent family income and cognition in adulthood, identifying education, stressful life events, inflammation, and family education expectations as significant mediators. Next, I examine the effects of writing-based stress manipulations on long-term memory and working memory, as these effects may mimic stress from financial worry. In doing so, I identify potential effects on working memory parameters. Finally, in …

Parkinson’S Disease And Processing Speed Theory Does Processing Speed Mediate Higher-Order Cognitive Functioning?, Priscilla Cuellar-Rocha

Electronic Theses, Projects, and Dissertations

Parkinson’s disease (PD) is a neurodegenerative disorder resulting in both motor and cognitive deficits. Salthouse (1990) proposed the Information Processing Speed (IPS) Theory that a reduced cognitive processing speed is a significant factor that accounts for the negative relationship between age-related variance and cognition. Parkinson’s is an idiopathic disorder, meaning that the cause is unknown, with most patients being 60 years and older. If the IPS theory suggests that an increased age affects the slowing of IPS, which then impairs cognition, PD, a disorder involving older adults, should also follow this pattern. However, no studies have assessed the IPS theory …

Parental Influence, Justin Burgess, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

An adequate level of parenting—providing enough nutrition, shelter, exposure to language and peers, or not harshly punishing children (punching, kicking, striking with a weapon)—seems to not have a long-term effect on cognitive development in children. Twin and adoption studies have found that intelligence is accounted for almost entirely by genes and nonshared environment, which includes peers, teachers, and unique experiences. However, there are parenting styles and types of home environments that are correlated with better school performance, stronger school engagement, and more words spoken at certain ages.

Perception, Chris Burley, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Perception is the process through which humans are able to select, organize, and interpret sensory input from the external environment. This process of selection, organization, and interpretation of external sensory stimulation results in our internal representation of the outside world, as well as our conscious experience. Through the process of perception, we are able to gain information and knowledge about our environment, allowing us to safely and effectively navigate in the world.
