The Joint Effect Of Bilingualism And Sleep On Executive Functions Among Children And Adolescents With Attention Deficit/Hyperactivity Disorder (Adhd), Yirou Jiang

Doctoral Dissertations

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that significantly impacts cognitive and behavioral functions, leading challenges for individuals across the lifespan. While extensive research has been conducted to understand the connection between executive functioning (EF) and ADHD, research findings related to the contributing factors of bilingualism and sleep still remains inconsistent (Bialystok et al., 2017). Investigating the joint effect between bilingualism and sleep on EF among children and adolescents with ADHD may help further clarify the connection between EF, language, and sleep, and facilitate the development of interventions from the perspective of these protective factors. EF encompasses cognitive processes …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

The Effects Of Sexual Orientation Stereotype Information And Prejudice On False Memories, Source Monitoring Errors, And Social Categorization Judgments, Julia Belen Strickland Nunez

Psychology Theses & Dissertations

Minoritized groups, such as the LGBTQ+ community, receive many harmful and destructive stereotypes from others. These negative views affect minorities because when people are recalling a memory, they fill in the gaps with general information that they know. When the schematic information is not accurate, people tend to remember information that was not originally presented; this is known as a false memory. When people accurately recall a memory, but not the source of the memory, it is known as a source monitoring error.

The current study investigated whether stereotype-consistent information leads to more false memories and source monitoring errors as …

Comparing Online Versus In-Person Administration Of Cognitive Tasks And Evaluating Their Predictive Utility Of Inattention Symptoms And Related Behaviors, Cameron Pothoven

Master's Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder associated with less developed working memory (WM) processes, theorized to be a core contributing factor in the development of ADHD and a predictor of ADHD symptom severity (Alderson et al., 2013; Rapport et al., 2008). Objective measures inclusive of working memory tasks, when used in conjunction with self-report measures, have been previously shown to increase the accuracy of diagnosing ADHD (Marshal et al., 2021. However, given that WM is typically assessed by a trained clinician, it is unclear how accurate and comparable online administration of adapted WM tasks are to their in-person counterparts. …

Testing P300-Based Biometric Authentication Paradigms, Jordan Razzak

Electronic Theses and Dissertations

Bench research suggests that P300 amplitude is greater in response to self-relevant stimuli compared to familiar stimuli. This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …

The Influence Of Shape Complexity And Exploratory Behavior On Grasping, Mckenzie Gunter

Dissertations

People can orient and configure their hands in many ways in order to grasp objects. The current study investigates how object shape and hand placement influence graspability of objects, and how experimentally imposed constraints on grasping type alter grasping behavior. In a recent study, Gunter and Hajnal (under review) found that the ratio of object curvature and maximal handspan is the variable that defines the affordance of graspability. The current study aims to extend these findings by employing a more precise measurement of finger placement in two experiments using 3D printed objects as stimuli. To capture varying complexities of object …

What Makes A Cozy Game Cozy? Looking Through The Lens Of Feminism And 4e Cognition, Mary Catherine M. Wilcox

All Theses

Why do some games feel cozy, and others miss the mark, even if they are tricked out in bright colors and festooned with bows? This thesis examines the emerging genre of “cozy games” to better understand why some titles successfully evoke comfort and relaxation while others fail, despite relying on conventionally cute aesthetics or farming-sim mechanics. Although cozy games have grown rapidly in popularity over the past decade, the genre remains under-studied and is often dismissed as frivolous, reflecting the broader historical devaluation of media associated with women. Accordingly, this study argues that understanding cozy games requires examining women’s relationship …

Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Assessment And Classification Of Idiosyncratic Behavioral Sequences In Rodent Navigation, Max G. Segal

Psychology ETDs

The Morris Water Task (MWT) has been the gold standard assessment of place learning and memory for over four decades, yet the processes that contribute to successful navigation are not completely understood. It is generally posited that rats learn to navigate directly to a place; however, navigation is not perfectly direct but contains variation in swim speed and trajectory resulting in efficient, yet suboptimal paths. Gonçalves-Garcia et al. (2024) demonstrated that path topography is quantitatively similar across trials within individual rats for a given start location, and dissimilar between rats and different start locations within rat. This suggests rats may …

Stop Blaming My Users: Illumination Of The Technocentric Mythos Bias, Ervin H. Frenzel, Richard Lightcap

Journal of Cybersecurity Education, Research and Practice

 Abstract -This conceptual essay addresses the need for systemic and systematic transdisciplinary analytical techniques within cybersecurity and technical security. This conceptual essay is contingent upon recognition that cybersecurity is not simply technical in nature, it does not need an adversary, and more importantly it is based upon systems engineering and systems thinking.  The essay contributes a socio-technical attribution chain and field-specific ontology/taxonomy which distinguish user-triggered events from root causes, latent conditions, technical debt, validation failures, governance failures, and attribution bias before assigning responsibility to end users. It systematically defines an ontology inclusive of developer technical debt, organizational debt arising from …

Sleep Restriction And Its Affects On Mood, April M. Rummery Lamb

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Sleep plays a fundamental role in the human body being able to function effectively, in particular it plays an essential role in mood regulation. Previous research on sleep and mood has found that there is a correlation between receiving an inadequate amount of sleep and having a negative mood. However, the current field has mostly looked at the relationship between disordered sleep and mood disorders as opposed to everyday sleep patterns and daily mood. The present study aims to look at how sleep restrictions which occur naturally (not caused by sleep disorders such as insomnia) effect daily mood. To conduct …

Exploring Primary Care Providers’ Compassionate Care And Their Evidence-Based Practice With Death, Grief, And Loss: Patient Experience And Perspective, Kathryn Krzykala

Dissertations

Research on primary care providers’ (PCPs) education regarding Death, Grief, and Loss (DGL) remains limited. Specifically, data is lacking regarding patients' perceptions and opinions on what they need and expect from their PCPs regarding grief and loss. This exploratory mixed-method study comprised 146 participants who had experienced death and non-death loss. It examined participants' perceptions of 1) PCP compassion, 2) PCP utilization of evidence-based grief and loss practices, 3) their own level of comfort discussing DGL with their PCPs during medical visits, and 4) their personal grief and loss experiences. The findings revealed that PCPs' grief-informed evidence-based treatment, as reflected …

The Relationship Between Cognitive Control And Individual Differences In Working Memory Capacity: A High-Density Eeg Study, Conghao Gao

All NMU Master's Theses

Empirical evidence has suggested a close relationship between human working memory capacity and cognitive control approaches. Proactive control refers to the anticipatory, sustainable maintenance of cognitive control process. However, the relationship between higher working memory capacity and the use of proactive cognitive control has been inconsistent. Understanding the neural bases would substantially expand our current understanding of cognitive control and working memory models. Specifically, the examination of P3b amplitude, part of the event-related potential, evoked by a cue would provide further understanding in neural mechanisms of cognitive control. The current study examined participants’ cognitive control approaches and their electrocortical activity …

Animal Assisted Interventions For Older Adults Experiencing Cognitive Impairment, Preeti Bachu

Psychology

As individuals age, they often experience gradual declines in cognitive abilities that ultimately affect their quality of life and independence. Severe cognitive decline is not necessarily a natural or universal part of the aging process and tends to be exacerbated by various neurodegenerative diseases, most notably Alzheimer's disease (Colita et al., 2024). There have been promising outcomes of animal assisted interventions in improving the conditions of several populations and spaces, including educational, rehabilitative, and therapeutic settings. Animal assisted therapy specifically is delivered by a qualified or licensed health professional. Previous research has shown a large benefit in long-term memory, verbal …

From Pathology To Ecology: Rethinking Student Well-Being Through Consciousness-Centered Education, Molly Beauregard

Journal of Conscious Evolution

This article revisits a five-year mixed-methods study conducted from 2012 to 2018, involving 207 student participants (n = 207), of an undergraduate sociology course—Consciousness, Creativity, and Identity—that integrated group meditation and mindfulness into a standard curriculum. Earlier analyses interpreted positive outcomes primarily as reductions in stress and improvements in attention among students. This paper reconsiders that interpretation, arguing that such a framing risks locating dysfunction within students rather than the social and cultural environments they inhabit.

Drawing on an ecological perspective, the study reexamines survey, reflection, and interview data documenting changes, not only in affect and attention, …

The Nature Of Physical Bravery: A Principal Component Analysis Of Bravery Using Personality Attributes, Trauma History, And Resilience In A Mixed Military And Civilian Sample, Colin Simsarian, Daniel Baldini, Brenda E. Hammond, Julianna Christofi, Sana F. Usmani, Holly M. Mcgrath, Carolina Rader, Erik Wendel Rice, James Moses, Bruce Bongar

Heroism Science

Heroism is a complex phenomenon shaped by psychological constructs such as bravery and courage, yet empirical research on physical bravery remains limited. This study examined the relationships among physical bravery, personality traits, trauma history, and resilience in a sample of military servicemembers and civilians (N = 197; M age = 27.69). Participants completed the Physical Bravery Survey, and data were analyzed using principal component analysis. Results identified four components explaining 70.52% of the variance in responses. Findings suggest that physically brave individuals tend to be adventurous, cognitively flexible, self-confident, humorous, resilient, and more likely to report a history of trauma. …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Racism In The Science And Practice Of Psychotherapy, Richard E. Redding, Craig L. Frisby

Psychology Faculty Articles and Research

We discuss a recent controversy that occurred in The Cognitive Behavioural Therapist over whether Lilienfeld’s critical views on microaggressions theory and research reflect racist beliefs, as alleged by some. This is one of many recent examples of a profoundly antiscientific practice whereby racism allegations chill scientific debate and open inquiry on important research issues. This produces an overtly politicized science that has a corrosive effect on scientific progress and ultimately the useful application of research in clinical practice. The microaggressions controversy provides an especially useful vehicle for challenging this state of affairs given the widespread application of microaggressions theory, including …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …
