The Physiological And Psychological Performance Effects Of Multi-Ingredient Pre-Workout Supplements In Females During Resistance Training, Mariah L. Snyder

EWU Masters Thesis Collection

In recent years, the use of supplements to aid resistance training performance has increased, particularly through the consumption of multi-ingredient pre-workout supplements (MIPS). However, limited research exists regarding the efficacy of MIPS on physiological and psychological performance in resistance-trained females.

PURPOSE: To determine the physiological and psychological performance effects of MIPS compared to a placebo and caffeine-only supplement in resistance-trained females.

METHODS: Resistance-trained females (n=10) volunteered for the study. One-repetition maximum (1RM) was established at baseline for leg press (LP) and bench press (BP). A within-groups, double-blind, randomized, and counterbalanced design was used to assign the four supplement drinks (i.e., …

Examining Foods And Beverages Served And Child Food Insecurity Across Early Care And Education (Ece) Programs In Communities With High Rates Of Obesity And Food Insecurity, Deepa Srivastava, Lucy R. Zheng, Dipti A. Dev

Department of Child, Youth, and Family Studies: Faculty Publications

The purpose of this study was to examine implementation of serving food and beverage evidence-based practices (nutrition EBPs) across CACFP participating licensed childcare centers (CCCs, n = 51) and family childcare homes (FCCHs, n = 49) in central California. Results indicated that FCCHs reported significantly higher (p < .05) implementation of nutrition EBPs and barriers than CCCs. Both CCCs and FCCHs refer families to WIC/SNAP when they observe child food insecurity and control how much food is served to children. It is important to consider organizational structure (CCCs, FCCHs) and child food insecurity when developing policies/interventions for improving implementation of nutrition EBPs in ECEs.

Effects Of Light/Dark Cycle Shifts On Delay Discounting, Katya A. Nolder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Shift-work conditions are a necessity for the constant provision of certain medical, industrial, and commercial services in modern society. Shift work is associated with the increased risk of many negative health outcomes, including type 2 diabetes, heart disease, reproductive issues, and cancer. Shift workers experience multiple levels of circadian-rhythm disruption, which may increase maladaptive decision making, and this may mediate the relation between shift work and negative health outcomes. Circadian-rhythm disruptions can be systematically investigated in the basic laboratory, and one type of procedure involves changing the light/dark cycle in the animal vivarium. The current study investigated effects of light/dark …

Sentence Length And Perceptions Of Dangerousness As A Function Of Race, Attributional Complexity, And Ability To Meet Bail, Hannah Baldwin

Psychology Theses

Defendant race and ethnicity impact sentencing length decisions, leading to discrimination in the criminal justice system. Aspects of the pretrial process that strongly correlate with a defendant’s socioeconomic status, the use of cash bail, may also influence sentencing length, given the negative stereotypes about individuals of lower socioeconomic statuses. Relatively few studies have explored the impact of cash bail use on sentencing decisions or sought to understand why use of cash bail might influence these decisions. The current study investigates the impact of defendant ability to meet bail (yes v. no) on judgments of sentence length and dangerousness within the …

The Predictive Effect Of Parent Closeness On Substance Use For Coping In Adoptees: An Application Of Motivational Models Of Substance Use, Alison B. Klein

Psychology Theses

To explain a previously observed triad of substance abuse, adoption, and poor mental health adjustment in adoptees, the proposed study applies the Substance Use Motivation Model. This model would suggest that adoptees are motivated to use substances to negatively reinforce (remove or mitigate) depression and anxiety symptomology. Parent closeness is an established protective factor against negative mental health symptomology and substance use, suggesting closeness may influence the relationship between negative mental health symptomology and motivations to use substances for coping. To test this relationship, 100 adoptees were administered the Substance Use Motives Measure (SUMM), the Personal Health Questionaire-9 (Depression), the …

The Evolution Of Stereotypes About Alcohol Dependency In Film: Gender, Family, And Treatment, Jordan Sweenie

Psychology Theses

When watching films, people seek reflections and depictions of themselves and their experiences, something that they can understand and relate to. Movies are often looked at to decide, either subconsciously or consciously, how we view society, widespread issues, and one another—Oscar Wilde wrote that “Life imitates Art far more than Art imitates Life” (Wilde, 1891). This is particularly true in how we as a society view mental illness, and what kinds of stigma are reinforced or rejected through the film industry. Accurately portraying any form of mental illness in film can be difficult, as experiences are subjective and no two …

Examining The Effect Of Witnessing Sexual Harassment On School Engagement: The Moderating Role Of Gender, Emily Sgritta

Psychology Theses

The following study investigated the potential relationships between directly or indirectly witnessing sexual harassment, the witness’ gender, school engagement, and psychological distress. Participants from an undergraduate university (N = 168) responded to a survey in which they answered questions relating to witnessing sexual harassment and their psychological distress, burnout, school engagement, and perceived social support after the event. For purposes of analyses, potential relationships on psychological distress and school engagement were examined further. Participants who directly witnessed sexual harassment reported lower school engagement than participants who didn’t report directly witnessing sexual harassment. Direct witnesses reported lower levels of vigor, dedication, …

The Relationship Between Loneliness And Experiential Avoidance After Implementation Of A Self-Compassion Intervention, Alyssa Mielock

Graduate Research Theses & Dissertations

An individual’s perception of a social relationship is distinct from an individual’s difficulty forming and maintaining social relationships. Loneliness is defined as an individual’s distress resulting from the discrepancy between perceived and desired social relationship quality. In the short term, loneliness may act as a motivator for an individual to seek social support to minimize distress. However, long-term loneliness is associated with physical and psychological impairments. There have been several risk factors identified that contribute to chronic loneliness, such as social isolation, psychopathology, and ineffective coping strategies. Ineffective coping may be one mechanism by which loneliness is associated with psychopathology …

Dual Lives And Incongruent Selves: The Impact Of Culture And Parenting On The Development Of Self In Young Adults In Karachi, Pakistan, Sara Admani

SSLA Culminating Experience

This study explored the influence of culture and perceived parental expectations and control on the development of self. In addition, it examined the resulting incongruence between the ideal and real-self leading to false-self behaviour and mental health deterioration. Carl Rogers' theoretical framework on self, served as the basis for this research, which used an interpretative phenomenological analytic technique. In-depth interviews lasting between 30 and 45 minutes were used to gather the data. Eight participants (four men and four women) who attended the university Institute of Business Administration (IBA) and lived in Karachi were chosen using a combination of volunteer and …

Pathogen Disgust Is Associated With Interpersonal Bias Among Healthcare Professionals, Anastasia Makhanova, W. Allen Lambert, Ryan Blanchard, Joe Alcock, Eric C. Shattuck, Michael P. Wilson

Psychological Science Faculty Publications and Presentations

Background and objectives

Pathogen avoidance is a fundamental motive that shapes many aspects of human behavior including bias against groups stereotypically linked to disease (e.g. immigrants, outgroup members). This link has only been examined in convenience samples and it is unknown how pathogen avoidance processes operate in populations experiencing prolonged and heightened pathogen threat such as healthcare professionals. We examined whether healthcare professionals demonstrate the same link between pathogen disgust and intergroup bias as has been documented among the general population.

Methodology

Participants (N = 317; 210 healthcare professionals) were recruited using snowball sampling to take an online survey. …

Developing Resilience Online: Evaluation Of Synchronous And Asynchronous Resilience Interventions For Filipino College Students, Ma. Regina Hechanova, Rosanne M. Jocson, Arsenio S. Alianan, Junix Jerald I. Delos Santos, Jason O. Manaois, Gilda Gomez, Gina R. Lamzon

Psychology Department Faculty Publications

This study evaluated two forms of a resilience intervention amongst college students during the COVID-19 pandemic. Utilising a randomised controlled trial design; it examined the impact of a synchronous and asynchronous resilience interventions versus a control group that did a journaling intervention. Outcomes measured included coping behaviour; non-reactivity; wellbeing; stress; depression and anxiety. Participants consisted of Filipino college students randomly assigned to three groups: synchronous online resilience group (n = 135); asynchronous resilience group (n = 121) and control group (n = 127). Results revealed that students who went through the online synchronous resilience reported a significant reduction in depression …

Assessing Consistency Of Three Perfectionism Scales, Brianna Lawry

Williams Honors College, Honors Research Projects

Perfectionism is generally described as a personality trait characterized by excessively high standards, overly critical evaluations of performance, and disproportionate amounts of distress in response to perceived flaws or failure. However, there is some debate as to whether perfectionism is a stable personality trait or a fluctuating state attribute. To investigate this, the current study assessed the test-retest reliabilities of the three most widely used perfectionism scales (the APS-R, HFMPS, and FMPS) over a three-week period and examined the influence of various contextual variables. Data from this college sample (N=43; mean age=21; SD=3.7) demonstrated high reliability and internal consistency for …

Human Interaction With The Divine, The Sacred, And The Deceased: Topics That Warrant Increased Attention By Psychologists, Thomas G. Plante, Gary E. Schwartz, Julie J. Exline, Crystal L. Park, Raymond F. Paloutzian, Rüdiger J. Seitz, Hans-Ferdinand Angel

Psychology

Humans have likely been attempting to communicate with entities believed to exist, such as the divine, sacred beings, and deceased people, since the dawn of time. Across cultures and countries, many believe that interaction with the immaterial world is not only possible but a frequent experience. Most religious traditions across the globe focus many rituals and activities around prayer to an entity deemed divine or sacred. Additionally, many people–religious, agnostic, and atheists alike–report communication with their departed loved ones. During highly stressful times associated with natural disasters, war, pandemics, and other threats to human life, the frequency and intensity of …

Incorporating A Developmental Perspective Into Gene Identification Models For Alcohol Use Behaviors, Nathaniel S. Thomas

Theses and Dissertations

Frequent alcohol use can lead to alcohol use disorder, which accounts for three million deaths and over 133 million life years lost to disability and death worldwide per year. Alcohol use behaviors unfold across development, beginning with initiation of drinking and progressing through various escalating stages of use. Alcohol use behaviors are also under genetic influence. Genome-wide association represents the state-of-the-science statistical methodology for identifying genes associated with alcohol use outcomes. However, contemporary genome-wide association study (GWAS) methods typically do not account for variability in genetic effects throughout development. In this project, I applied novel multivariate genomic methods to combine …

Caregiver Acceptability Of Differential Reinforcement Procedures For Honest Reports Of Transgressions, Stephanie C. Bowar

University of the Pacific Theses and Dissertations

When measuring social validity, many researchers rely exclusively on subjective measures, such as questionnaires or surveys; however, these measures may fail to capture the variables that control later intervention adoption by stakeholders, and objective measures may capture these variables more accurately. Moreover, few researchers have investigated the adoptability of differential reinforcement (DR) interventions to increase children’s honesty about transgressions. We taught caregivers to implement the DR procedures reported in Lehardy et al. (2023) and measured the acceptability and adoptability of procedures using three measures: (1) a social validity questionnaire and rating scale immediately following training, (2) a concurrent-chains preference assessment …

Establishing Roots Before Branching Out: Parameter Recovery In Item Response Tree Models, Tyler Ryan

Browse all Theses and Dissertations

Item Response Trees are a type of item response model that incorporates information about conditional responding to items using a rooted tree graph structure. Researchers have used item response trees for common measurement tasks and for testing novel hypotheses. Previous simulation studies investigating item response trees either lack generalizability to the broad domain of their use or lack thorough investigation and reporting of the results. I conducted a simulation study to explore how sample size, test length, item characteristics, and tree structure affect both item and person parameter recovery for 1PL and 2PL models. The results suggested that, as with …

Autonomy :A Modern Perspective, Riley Schwanz

Browse all Theses and Dissertations

Organizational leaders want to retain employees who are healthy and motivated. Physical and mental health issues are on the rise in America for younger and older generations. Researchers have found that higher levels of autonomy relate to improved mental health, physical health, job satisfaction, performance, and the list goes on. However, a gap in the literature is a lack of understanding of the complex relationships between autonomy and outcomes, both functional and dysfunctional. I found that intrinsic motivation and autonomy support can compensate for lower levels of autonomy in one’s work. These new findings provide researchers and organizational leaders with …

Development And Validation Of A Norm Violation Sexual Harassment Scale, Krista N. Harris

Browse all Theses and Dissertations

Sexual harassment continues to be an important area of study. However, there’s a dearth of research regarding sexual harassment towards others that considers sex, gender, and sexual orientation. Previous research has suggested that gender harassment and heterosexist harassment are intertwined (Leskinen & Cortina, 2014), but little research has examined how the empirical and conceptual overlap of gender harassment and heterosexist harassment could allude to a more general construct, norm violation sexual harassment. Norm violation sexual harassment is an overarching construct focusing on norm violations rather than sex, gender, or sexual orientation specifically. Using two samples, my study demonstrates evidence for …

Leadership And Secure Base, Bincy Davis

Browse all Theses and Dissertations

Research on Attachment theory has established the need for secure base in adulthood (e.g., Hazan & Shaver, 1990). However, few researchers have explored the importance of secure base in a work setting. The purpose of my study was to examine the relevance of secure base in the leadership process. Results from pilot research (N = 272) showed that 13 leader behaviors were positively associated with secure base. Confirmatory factor analyses revealed that 5 factors underlay these 13 leader behaviors. Results from structural equation modeling provided support for a secure base model of leader behaviors in Study 1 (N = 272 …

Pragmatically Appropriate Abstractive Summarization Of Jtac Radio Conversations, Spencer M. Seals

Browse all Theses and Dissertations

In this work, I explore the development of computational methods for automatically creating after-action reports of JTAC radio conversations. Prior research has investigated related issues of sentence compression, text summarization, and conversation summarization (Banerjee, Mitra, & Sugiyama, 2015; Clarke & Lapata, 2008; L. Wang & Cardie, 2012; Raffel et al., 2020). However, this work makes limiting assumptions about what features are relevant to a summary and what sources of information should be included. I propose methods that combine knowledge from linguistic, procedural, and domain sources to address these limitations. Results indicate that the proposed model performs better than some of …

Short-Term Learning For Long-Term Retention : Dynamic Associative Memory, Joseph James Glavan Iv

Browse all Theses and Dissertations

Instead of characterizing transfer from short-term memory to long-term memory as the relocation of information from one structural system to another, I propose a theory that conceives of transfer as the learning processes that act on and transform the representations of the information itself. Dynamic Associative Memory posits that recently encoded memories are supported by active maintenance and the relevance of the current context. Over time, the current context becomes less relevant; therefore, the brain must learn contextually invariant associations between memories so that they may support themselves. I instantiated my theory in the ACT-R cognitive architecture and created a …

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 …

The Impact Of Pre-Experiment Walking On Distance Perception In Vr, Soheil Sepahyar

Dissertations, Master's Theses and Master's Reports

While individuals can accurately estimate distances in the real world, this ability is often diminished in virtual reality (VR) simulations, hampering performance across training, entertainment, prototyping, and education domains. To assess distance judgments, the direct blind walking method—having participants walk blindfolded to targets—is frequently used. Typically, direct blind walking measurements are performed after an initial practice phase, where people become comfortable with walking while blindfolded. Surprisingly, little research has explored how such pre-experiment walking impacts subsequent VR distance judgments. Our initial investigation revealed increased pre-experiment blind walking reduced distance underestimations, underscoring the importance of detailing these preparatory procedures in research—details …

Supporting Team Innovation With Design Thinking Cognitive Strategies, Lisa M. Casper

Dissertations, Master's Theses and Master's Reports

Innovation is a 21st-century skill needed to design new systems, solve challenging problems, and develop novel solutions. Design Thinking (DT) is a tool used to support team innovation. In this experiment, 145 students (47 teams) used one of two DT methods during a semester-long project to come up with an innovative solution to one of the UNESCO 17 sustainable development goals. The key experimental manipulation was during the DT Ideate phase where teams brainstormed potential solutions. Teams either used a baseline DT Ideate strategy or an expanded one with additional prompts during a 10-minute period. Results indicated that teams using …

Psychology And Criminology Students' Attribution Of Factors Contributing To Criminal Behaviors, Ava Marie Leahy

Senior Honors Theses and Projects

The purpose of this study was to investigate the differences in the attribution of contributing factors to criminal behaviors between psychology and criminology majors. To gauge participant perception, a carefully crafted vignette was presented to participants accompanied by questions asking participants to what extent eight variables (conformation to labels, hostile attribution bias, rational choice based on circumstances, poor attachments, mental illness, upbringing, insufficient deterrence, and learned behavior through observation) contributed to the perpetrator’s criminal behavior and for participants to rank-order these same variables from the largest contributors to the least. Participants were also asked to provide a sentencing recommendation for …

Ptsd Endorsement Among Diverse Populations During Covid-19 Pandemic, Noor Jassim

Senior Honors Theses and Projects

Posttraumatic stress disorder (PTSD) is a mental health diagnosis that is a reaction to very stressful experiences. PTSD may hamper the quality of life for individuals suffering from it. It has been shown that being part of disadvantaged groups racially and socioeconomically may pose a higher risk of experiencing PTSD. The stress component of PTSD is the imbalance between the demands of an environment and an individual's ability to cope. A mismatch between degree of demands and coping ability influences psychological and physiological well-being. The impact on well-being varies by stress being acute, chronic, or a combined state of acute …

Examining The Strong Black Woman Schema, Kaiya Keiko Haywood

Senior Honors Theses and Projects

Research about the Strong Black Women (SBW) schema shows that it can have harmful outcomes when individuals are given a specific SBW stereotype to consider (Donovan & West, 2015). I examined the benefits of the SBW schema when participants were given a schema description absent of a specific exemplar or stereotype, a description of a person characterized by mostly positive traits related to the schema (as found in pilot data). Participants then attempted to match the description with a Black woman (or not) and reported how inspiring and reassuring the protagonist made them feel. It was hypothesized that the description …
