Multiple Sclerosis Cognitive Scale (Mscs): A Brief Psychometrically Robust Metric Of Patient-Reported Cognitive Difficulty, James F. Sumowski, Joshua Sandry

Department of Psychology Faculty Scholarship and Creative Works

Background:

Existing metrics of patient-reported cognitive difficulties in multiple sclerosis (MS) are lengthy, lack psychometric rigor, and/or fail to query prevalent expressive language deficits.

Objective:

Develop a brief psychometrically robust metric of patient-reported cognitive deficits that includes language items; the Multiple Sclerosis Cognitive Scale (MSCS).

Method:

Exploratory factor analysis (EFA) was conducted on 20 Perceived Deficits Questionnaire (PDQ) items plus five newly developed language questions in a large MS sample and matched respondents without neurologic disease. Independent confirmatory principal components analysis (PCA) assessed EFA factor structure. Reliability of the new scale and subscales, and relationships with objective cognitive impairment and …

The Impact Of Time Of Night On Affect And Affective State Type: A Simulated Nightshift Study, June J. Pilcher, Christopher Ply

Publications

Nightshift workers experience circadian misalignment thus negatively impacting many physiological systems which can change subjective states such as affect. The current study examined change in affect and affective state across a simulated first nightshift. Ninety sleep-deprived college students (33% female) completed a series of surveys and tasks across four testing sessions during the night. The participants completed the Positive and Negative Affect Schedule at the beginning of each testing session. Using these affect scores, we derived four affective state types defined by high and low positive and negative affect (Self-actualizing-high positive affect with low negative affect, High affective-high positive affect …

The Various Forms Of Anger About Climate Change In Australia And Their Relations With Self-Reported Actions, Intentions, And Distress, Samantha K. Stanley, Zoe Leviston, Teaghan L. Hogg, Iain Walker

Research outputs 2022 to 2026

Action on societal issues is often precipitated by feelings of anger. This has been demonstrated reliably for responses to social inequality, but less for other issues. We build on nascent research documenting the links between climate anger, pro-environmental action, and psychological distress, by focusing on the contents of eco-anger. Using a sample of 5244 Australians, we found that 48.6% reported being at least ‘somewhat’ angry about climate change. Content analyses of the focus of this anger revealed diverse reasons for people's anger. The most common focus was others' inaction and apathy on climate change, followed by anger directed at deniers, …

A Meta-Analysis Of Accent Bias In Employee Interviews: The Effects Of Gender And Accent Stereotypes, Interview Modality, And Other Moderating Features, Henri T. Maindidze, Jason G. Randall, Michelle P. Martin‐Raugh, Katrisha M. Smith

Psychology Faculty Publications and Presentations

To address concerns of subtle discrimination against stigmatized groups, we meta‐analyze the magnitude and moderators of bias against non‐standard accents in employment interview evaluations. Results from a multi‐level random‐effects meta‐analysis (unique effects: k = 41, N = 7,596; multi‐level effects accounting for dependencies: k = 120, N = 20,873) demonstrate that standard‐accented (SA) interviewees are consistently favored over non‐standard‐accented (NSA) interviewees (d = 0.46). Accent bias is stronger against women compared to men, particularly when evaluator samples are predominantly female, and was strongly predicted by interviewers' stereotypes of NSA interviewees as less competent and, to a lesser extent, as less …

Conflicted Help-Seeking: Vulnerable And Grandiose Narcissistic Traits In College Students, Daniel G. Lannin, Rachel Brenner, Jake R. Solka, Amanda Martin, Anthony Hermann

Faculty Publications – Psychology

This study highlights distinct patterns in help-seeking behavior among college students with narcissistic traits, focusing on grandiose and vulnerable manifestations of these traits. Two undergraduate samples (N₁ = 398, N₂ = 424) completed measures of narcissistic traits, stigma, psychological distress, and help-seeking intentions. Higher levels of vulnerable narcissistic traits were positively linked to help-seeking willingness, with indirect effects through heightened distress (positive) and stigma (negative). In contrast, grandiose narcissistic traits showed no consistent direct or indirect effects on help-seeking behavior. These findings reveal that students with elevated vulnerable narcissistic traits may experience conflicting motivations for seeking help – driven by …

A Computational Analysis Of The Effect Of Hard Choices On The Individuation Of Values, Norberto M. Grzywacz

Psychology: Faculty Publications and Other Works

Background/Objectives: Experimental studies show that when an individual makes choices, they affect future decisions. Future choices tend to be consistent with past ones. This tendency matters in the context of ambivalent situations because they may not lead to clear choices, often leading people to make “arbitrary” decisions. Thus, because of choice consistency with the past, people’s decision-making values diverge. Thus, hard choices may contribute to the individuation of values. Methods: Here, we develop a Bayesian framework for the effects of cognitive choice consistency on decision-making. This framework thus extends earlier cognitive-science Bayesian theories, which focus on other tasks, such as …

Perceptual Complexity As Normalized Shannon Entropy, Norberto M. Grzywacz

Psychology: Faculty Publications and Other Works

Complexity is one of the most important variables in how the brain performs decision making based on esthetic values. Multiple definitions of perceptual complexity have been proposed, with one of the most fruitful being the Normalized Shannon Entropy one. However, the Normalized Shannon Entropy definition has theoretical gaps that we address in this article. Focusing on visual perception, we first address whether normalization fully corrects for the effects of measurement resolution on entropy. The answer is negative, but the remaining effects are minor, and we propose alternate definitions of complexity, correcting this problem. Related to resolution, we discuss the ideal …

Examining The Role Of Executive Functioning In Self-Care Of Type 1 Diabetes Among Youth, Erin Vogel

Doctor of Psychology (PsyD)

This study explores the relationships between youth executive functioning, symptoms of depression, the self-management (self-care) of Type 1 diabetes (T1D), and glycemic control, a proxy for diabetes-related health outcomes. Utilizing archival clinical data from a universityaffiliated pediatric diabetes clinic, the study tested a priori hypothesized associations between depressive symptoms, executive functioning, diabetes self-care, and health outcomes. Parent and youth measures included the Patient Health Questionnaire-9 to assess youth depression, the Diabetes Related Executive Functioning Scale-Short Form to assess youth executive functioning, and the Diabetes Self-Management Profile-Short Form to assess youth diabetes-related self-care behaviors. Hemoglobin A1c (HbA1c) assays were a secondary …

The Effect Of Voir Dire Variations On Juror Disclosures, Joshua A. Haby

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

Voir dire, sometimes referred to as jury selection, is the legal process the court uses to pursue an impartial jury. The presiding judge controls many aspects of how voir dire proceeds. In deciding voir dire variations, the judge presumably engages in a calculus weighing factors like the goal of voir dire, time, and specific trial needs to determine appropriate procedures. Certain procedures are considered expansive and others limited. Where expansive procedures provide more information from jurors, they may take longer; limited procedures may be more expeditious but limit access to information from jurors (Hans and Jehle, 2003; Mize, Hannaford-Agor, and …

A Head-To-Head Comparison Of Situational Judgment Tests And Assessment Centers For Measuring And Predicting The Same Performance Dimensions, Iman Shakeri, Filip Lievens

Research Collection Lee Kong Chian School Of Business

To date, a limited set of studies have compared the criterion-related validity of low-fidelity (SJT) versus high-fidelity (AC) simulations for predicting job performance. Unfortunately, these studies validated these simulations through the overall assessment rating (OAR) instead of on the basis of specific dimensions. Given SJTs and ACs were compared that measured different dimensions, our understanding of the relative and comparative validity of these assessment approaches in measuring the same set of dimensions is still limited. Therefore, this study aims to conduct a head-to-head comparison of the criterion-related validity of the AC and the SJT (and their incremental validity) while keeping …

Childhood Sexual Abuse Among Asian American Adults: Prevalence, Cultural Barriers, And Mental Health Implications, Kruti S. Chaliawala, Liliana Rojas-Guyler

Dignity: A Journal of Analysis of Exploitation and Violence

Childhood sexual abuse represents a significant public health concern, particularly within minority populations, where adversities and complications are prevalent but understudied. This study aims to investigate the mental health of Asian American childhood sexual abuse survivors and explore the prevalence of childhood sexual abuse among Asian adults. A secondary analysis of the 2020 Behavioral Risk Factor Surveillance System (BRFSS) data was conducted, including a final sample of 1,894 Asian adults (0.16% of the total sample size of N = 401,958). Among these participants, 16.8% (n = 1,894) reported experiencing CSA. The most common forms of abuse were inappropriate touching …

The Role Of Acculturative Stress, Discrimination In Healthcare Settings, And Migration-Related Trauma On Hiv Prevention And Mental Health Among Immigrant Hispanic Sexual Minority Men: An Integrated Model Of Acculturation And Minority Stress, Jonathan Lopez Matos

Dissertations, Theses, and Capstone Projects

This dissertation expands Minority Stress Theory (MST) by integrating the Fourfold Acculturation Model (FAM) to examine the impact of psycho-sociocultural stressors on health outcomes among immigrant Hispanic sexual minority men (HSMM) in the U.S. The study explored how language proficiency, acculturative stress, discrimination in healthcare, migration-related trauma, and stress-related growth influence HIV prevention behaviors and mental health. Survey data from 194 Spanish-speaking immigrant HSMM revealed that monolingual Spanish speakers experienced significantly higher acculturative stress than bilinguals. Acculturative stress significantly mediated the association between stressors and health outcomes, such as HIV testing and mental health symptoms. Discrimination and trauma were directly …

Category Learning Reorganizes Internal Representations Of Visual Artworks, Aishwarya Gurung

Dissertations, Theses, and Capstone Projects

How are categories of art internally represented, and how can we capture those representations systematically? Investigating category learning in the context of complex, multidimensional stimuli like visual artworks presents unique challenges due to their inherent variability and perceptual complexity. Artworks engage multiple cognitive processes and are shaped by both sensory-driven mechanisms and top-down influences like prior knowledge, making them uniquely suited for studying how structured categorical knowledge interacts with perceptual and aesthetic judgments. The present study addresses these questions by utilizing machine-learning tools to construct and implement a two-dimensional similarity space of 400 existing artworks painted by two artists from …

The Elephant (And Donkey) In The Room: The Effects Of Political Ideology On Diversity Training Effectiveness, Luke P. Kayga

Dissertations, Theses, and Capstone Projects

In recent years, the prevalence of Diversity, Equity, and Inclusion (DEI) trainings in organizations has grown significantly (Wang et al., 2024). DEI trainings are typically designed with the purpose of educating organizational members on DEI-related content and promoting feelings of inclusion in the workplace (Devine & Ash, 2022). Much like many other types of organizational training efforts, the effectiveness of DEI trainings is contingent on a variety of input factors. One such factor that has been extensively covered in the broader training literature but relatively understudied in DEI training research is trainee characteristics. Since DEI trainings are values-based, ethically prescriptive …

Tracing Reverberations: Vietnamese Refugee Mothers' Adaptations To Complex Structural Forces And Intergenerational Engagements, Kim Khanh Nguyen-Nalpas

Dissertations, Theses, and Capstone Projects

The main purpose of this study is to learn how refugee mothers adapt to hierarchical systems of oppression with agency and resistance. Global refugee forums and decades of past research on refugees have identified the importance of increasing agency to best support refugees as they resettle. Previous research by the author has demonstrated that refugee mothers model resistance to oppressive systems which has implications for children who witness this resistance. In-depth interviews were conducted with 19 Vietnamese refugee mothers to explore their mothering practices, how they adapted given the socio-political forces shaping their lives, and how these adaptations reverberated through …

Proximity In Pixels: The Moderating Roles Of Structural And Psychological Distance On Behavioral Leadership Effectiveness, Ethan J. Ray

Dissertations, Theses, and Capstone Projects

With a sharp increase in virtual working arrangements in recent years, there is a distinct need to reevaluate what constitutes effective leadership at a distance. Although research on virtual leadership exists, it has often lacked a focus on specific leader behaviors and the psychological intricacies unique to virtual work settings. The present study examines followers' perceived effectiveness of two enduring leadership behavior categories: task-oriented and relationship-oriented. Utilizing dyadic distance theory, the study tested whether perceived effectiveness of these behaviors is contingent not only on the tangible effects of virtual work, referred to as structural distance, but also on the intangible …

Constructing A Parameterized Stimuli Space Suitable To Induce Controlled Changes In Human And Machine Perceptual Systems, Andrew Frankel

Dissertations, Theses, and Capstone Projects

Traditional computer vision applications focus on objective tasks, such as object detection, classification, or segmentation. Much of human experience is inherently subjective, such as our personal response to artwork. Individualized experiences are challenging to replicate in a controlled laboratory environment, as those experiences depend on the unique history and internal models of the observer. This work presents a technique to construct a 2-dimensional parameterized stimuli space suitable to induce controlled changes in the perceptual systems of both human and machine observers. Our contributions are threefold:

1. Using a balanced dataset of 8,800 fine art images spanning 11 art movements and 88 …

A Benjaminian Rumination Of Grasses And Tomatoes In Contemporary Anatolian Film, Ceren Izci

Dissertations, Theses, and Capstone Projects

This thesis interprets the intersection of history, ecology, and politics through two contemporary Anatolian films: Nuri Bilge Ceylan’s About Dry Grasses and Murat Fıratoğlu’s One of These Days When Hemme Dies. We focus on the films’ portrayal of social relations and relationships to other living beings through interpreting the temporal layers and historical tensions present in the plots of the films. We introduce the paper by pondering over the question of whether these films are political. Drawing on Walter Benjamin’s concepts of “first nature” and “second nature”, the first chapter introduces the philosophical framework for understanding the connection between …

Differential Mechanisms Of Access In Working Memory: Comparing Global And Selective Retrieval, Jade M. Turbides

Dissertations, Theses, and Capstone Projects

Working memory (WM) is essential for numerous cognitive tasks, yet the mechanisms underlying selective access to specific subsets of its contents vs. global, nonselective access remain incompletely understood. Context-specific selection of individual items from WM has been found to be more time-consuming and error-prone than globally accessing all memory contents. This study investigates whether the performance costs of selective WM access arise primarily from demands on item-context binding memory. Previous research has suggested that only selective access relies on memory for item-context bindings whereas global access can solely rely on item memory. Across two experiments, we employed task paradigms that …

The Perspectives Of Play Advocates On Children’S Unstructured Play In Turkey, Bengi Sullu

Dissertations, Theses, and Capstone Projects

The Convention on the Rights of the Child has established children’s rights to non- discrimination, development, participation and the observance of their best interests. With this recognition, there has been a growing global interest in acknowledging play as a right. Yet unstructured play, in which children can choose when, where and how to play, with control over their play, has not received the same attention, support and investment as organized, structured play (UNCRC General Comment 17, 2013). The way adults perceive and support play shapes the play opportunities that are available to children (Bianquin, 2018; Göl-Güven, 2017). Additionally, institutions and …

Synchronizing Work And Teaching Practices With The Spatial Dna Of Distributed Work And Learning, Manju Aishwarya Adikesavan

Dissertations, Theses, and Capstone Projects

Phygitality, the seamless and synergistic integration of physical and digital realms, is an indispensable and irrevocable part of contemporary office-based work. Phygitality facilitates spatially and temporally distributed or multi-local working where employees work from diverse locations such as their home, office, and third places at any time of day or night. It also makes nonterritorial working at temporary workspaces accessed on a session-by-session basis possible.

This dissertation examines how phygital, multi-local, and nonterritorial working reshape individual and group work behaviors, organizational spatial practices, work-centric settings, non-work-centric settings, neighborhoods, cities, and regions. The Spatial DNA of Distributed Work encapsulates a conceptual …

Inherited Wounds: Generational Trauma In Postcolonial Film And Narrative Fiction Of The Global South, Sabrina Testi Melgarejo

Dissertations, Theses, and Capstone Projects

The theorization of trauma in literary studies emerged in the 1990s, evolving from its physiological origins to a multidisciplinary framework encompassing literature, psychology, and history. However, classical trauma theory, rooted in Western scholarship and focused on singular traumatic events, has been criticized for its limitations in addressing collective and ongoing trauma in non-Western contexts. This thesis responds to a call for a more inclusive approach to trauma studies, examining how multi-generational and cultural trauma is represented in non-Western postcolonial films and literature from the Global South, including works from the Philippines, Sri Lanka, Cuba, Angola, Mozambique, Vietnam, and Lebanon.

Beyond The Sum: A Network Analysis Of Adverse Childhood Experiences And Behavioral Outcomes In Justice-Involved Youth, Jennifer Yang

Dissertations, Theses, and Capstone Projects

This dissertation examines gender-specific patterns of adverse childhood experiences (ACEs) among justice-involved youth using network analysis. Despite experiencing higher rates of childhood adversity, female youth show lower recidivism rates than males, presenting an empirical paradox. Using a sample of 19,454 justice-involved youth (75% male), this study applies novel network methods to understand how ACEs and behavioral outcomes are organized across gender. Findings reveal distinct network architectures: female youth maintain more integrated but vulnerable networks, while males show more compartmentalized but stable structures. Female recidivists demonstrate systematic network destabilization when compared to non-recidivists, characterized by a 39% reduction in network density, …

Beauty Comes With A Price: But How Much Is It Worth It, Fabliha Afia

Dissertations, Theses, and Capstone Projects

The global skincare market, valued at 104.24 billion dollars in the year 2022, is very heterogeneous, ranging from prestige brands to more drugstore types. Even when the same key ingredients are present, the latter often sells for much higher due to branding and packaging and the aura of prestige created. This capstone project entitled "Beauty comes with a price: but how much is it worth?" investigates if such higher costs are justified due to superior quality or are driven by non-functional factors. It systematically compared the high-end versus drugstore skincare products in categories like sunscreens, serums, and exfoliants with respect …

Religion: Evolutionary Foundation For, Nicole Fellice Ko, Norman P. Li

Research Collection School of Social Sciences

Religion refers to a structured set of spiritual beliefs and rituals. Evolution refers to the process by which living organisms transform and develop over time. Religion—the belief in spiritual beings—influences nearly every aspect of life, making it challenging to understand many phenomena without considering its influence (Bloom, 2012). About two-thirds of the world’s population is religious (Kramer & Tong, 2024); 70% of Americans consider themselves spiritual, and 83% believe they have a spirit separate from their bodies (PEW Research Center, 2023). Throughout history, religion has played a significant role in conflicts like war and continues to influence contemporary issues such …

It's Just A Game! Effects Of Fantasy In A Storified Test On Applicant Reactions, Marie L. Ohlms, Klaus G. Melchers, Filip Lievens

Research Collection Lee Kong Chian School Of Business

There is increasing attention to storification of assessments (i.e., embedding a storyline into a non-storified assessment) in research and practice and to gamified and game-based assessment in general. However, there is a surprising lack of agreement and of recommendations regarding what level of fantasy of the storyline one should choose for the storification from the perspective of applicant reactions. A distinction is typically made between fantasy (e.g., fighting aliens) and realistic (e.g., workday simulations) storylines, with both choices having their advantages and disadvantages. In this study, a sample of 195 participants was shown either a storified realistic test, a storified …

Faculty, Staff and Student Publications

INTRODUCTION: Motoric cognitive risk (MCR) is a pre-dementia syndrome characterized by mobility and cognitive dysfunction. This study conducted a proteome-wide study of MCR and compared the proteomic signatures of MCR to that of mild cognitive impairment (MCI).

METHODS: Participants were classified as MCR using a memory questionnaire and 4-meter walk. We measured 4877 plasma proteins collected during late-life and midlife. Multivariable logistic regression related each protein to late-life MCR/MCI. MCR-associated proteins were replicated internally at midlife and in an external cohort.

RESULTS: Proteome-wide analysis (n = 4076) identified 25 MCR-associated proteins. Eight of these proteins remained associated with late-life MCR …

Quantified Lives: Data, Bias, And The Cost Of Categorization, Colin F. Geraghty

Dissertations, Theses, and Capstone Projects

This project critically examines how statistical methods and data visualization have historically been used to categorize, rank, and control human populations. By exploring the works of key figures like Francis Galton, Karl Pearson, and R.A. Fisher, it traces the evolution of categorization frameworks from their eugenic roots to modern applications in artificial intelligence and global metrics like the World Happiness Report. Through interactive visualizations and historical analysis, the project invites users to question the legitimacy of these frameworks and reflect on their impact on society. At its core, this work emphasizes the need to move beyond rigid classification systems, challenging …
