The Application Of Bayesian Meta-Analytic Models In Cognitive Research On Neurodevelopmental Disorders, Nic Zapparrata Jun 2024

The Application Of Bayesian Meta-Analytic Models In Cognitive Research On Neurodevelopmental Disorders, Nic Zapparrata

Dissertations, Theses, and Capstone Projects

Meta-analysis is the systematic review and quantitative synthesis of specific areas in literature and is an important quantitative tool for researchers interested in synthesizing a particular body of research. The current research used meta-analysis to investigate processing speed in two neurodevelopmental disorders. This dissertation consisted of four meta-analytic papers. The first paper was a meta-analysis that synthesized a large body of research on processing speed, measured via reaction time (RT) measures, in groups of individuals diagnosed with autism spectrum disorder (ASD) versus age-matched neurotypical comparison groups. This research was motivated by two previous meta-analyses in the literature on processing speed …


Embodied Co-Regulation: A Neuroregulatory-Informed Dance/Movement Therapy Transition Intervention Method For Arousal Regulation For Adolescents In A Partial Hospitalization Program, Anamaria Guzman May 2024

Embodied Co-Regulation: A Neuroregulatory-Informed Dance/Movement Therapy Transition Intervention Method For Arousal Regulation For Adolescents In A Partial Hospitalization Program, Anamaria Guzman

Expressive Therapies Capstone Theses

This thesis introduces a novel Dance/Movement Therapy (DMT) approach, focusing on nervous system arousal regulation during transitions between therapy groups. The core of the method involves a brief 5-minute exercise designed to modulate arousal levels, encompassing alertness and energy, aiming to establish a baseline homeostasis. Rooted in Polyvagal Theory and Developmental Neurobiology, the approach assumes the co-regulation of nervous systems within a group therapeutic setting. Two primary outcomes are self-assessed: 1) somatic experiences documented through narratives and 2) nervous system biodata measured using the Flowtime headband monitoring of brainwaves, heart rate, and other biomarkers. Results indicated that all six sessions …


Buffering Effects Of Negative Intergroup Contact Through Complex Social Identities, Liora Morhayim Mar 2024

Buffering Effects Of Negative Intergroup Contact Through Complex Social Identities, Liora Morhayim

Masters Theses

Although negative intergroup contact occurs less frequently than positive contact, negative contact can more strongly influence outgroup attitudes and behaviors due to the effect of category salience in the generalization process. The present study (N =306) tests whether being aware of an outgroup member’s complex social identity will serve as a buffer against the adverse impact of a negative intergroup contact experience on outgroup attitudes. In a 3X2 between-subjects design, social identity complexity (SIC) of an outgroup confederate (high versus low versus control) and the valence of contact (neutral versus negative) were manipulated. Participants interacted with an outgroup confederate …


Examining Differences In Self-Concept And Language Between Monolingual And Bilingual Undergraduate Students, Marilyn Vega-Wagner Jan 2024

Examining Differences In Self-Concept And Language Between Monolingual And Bilingual Undergraduate Students, Marilyn Vega-Wagner

University of the Pacific Theses and Dissertations

The literature is lacking in studies that examine self-concept and language status among individuals older than adolescence. The purpose of this study is to conduct a quantitative nonexperimental comparative design to examine differences in self-concept and language status (monolingual or bilingual) between male and female undergraduate students in California. A total of 97 participants were examined in the study. The researcher conducted descriptive statistics on the demographics as well as a MANOVA and an ANOVA to answer the proposed research question. Based on the findings presented, the researcher failed to reject the null hypothesis of research question 1: There is …


The Effect Of Email Communication On Professor-Student Rapport, Academic Self-Efficacy, Resiliency, Motivation, And Spirituality, David J. Heim Jan 2024

The Effect Of Email Communication On Professor-Student Rapport, Academic Self-Efficacy, Resiliency, Motivation, And Spirituality, David J. Heim

MSU Graduate Theses

Student retention and success rates are an increasing concern among collegiate administrators and educators. This study examined the influence of a college instructor’s email communications on professor-student rapport, student academic self-efficacy, resilience, motivation, and success. Researchers hypothesized that the student participants who received the encouraging email communications from their professor would demonstrate higher levels of professor-student rapport, higher levels of academic self-efficacy, resiliency, and success compared to the students who receive standard email communications from their professor. Five scales were utilized in this study including Professor-Student Rapport Scale, Academic Self-Efficacy Scale, Academic Resilience Scale (ARS-30), Daily Spiritual Experience Scale (DSES), …


Consistent Across Situations? A Person Specific Approach To Examining A Long-Standing Paradox., Muchen Xi Dec 2023

Consistent Across Situations? A Person Specific Approach To Examining A Long-Standing Paradox., Muchen Xi

Arts & Sciences Electronic Theses and Dissertations

Bem and Allen (1974) address the person situation debate by proposing that there are some people behave more consistently, which can be better “explained” try personality traits, than others who are more influenced by situations. However, with failures to directly replicate Bem and Allen’s study, the existence of individual difference in cross situation consistency of behaviors remaining unclear. The current study addressed open questions that arose from the personality consistency debate by employing Mixed Effect Location Scale Model (MELSM) in an intensive longitudinal study. We found 1) there are individual difference in the overall behavioral consistency across situations; 2) there …


A Psychometric Analysis Of Natural Language Inference Using Transformer Language Models, Antonio Laverghetta Jr. Oct 2023

A Psychometric Analysis Of Natural Language Inference Using Transformer Language Models, Antonio Laverghetta Jr.

USF Tampa Graduate Theses and Dissertations

Large language models (LLMs) are poised to transform both academia and industry. But the excitement around these generative AIs has also been met with concern for the true extent of their capabilities. This dissertation helps to address these questions by examining the capabilities of LLMs using the tools of psychometrics. We focus on analyzing the capabilities of LLMs on the task of natural language inference (NLI), a foundational benchmark often used to evaluate new models. We demonstrate that LLMs can reliably predict the psychometric properties of NLI items were those items administered to humans. Through a series of experiments, we …


A New Method To Determine The Posterior Distribution Of Coefficient Alpha, John Mart V. Delosreyes Oct 2023

A New Method To Determine The Posterior Distribution Of Coefficient Alpha, John Mart V. Delosreyes

Psychology Theses & Dissertations

There is a focus within the behavioral/social sciences on non-physical, psychological constructs (i.e., constructs). These constructs are indirectly measured using measurement instruments that consist of questions that capture the manifestations of these constructs. The indirect nature of measuring constructs results in a need of ensuring that measurement instruments are reliable. The most popular statistic used to estimate reliability is coefficient alpha as it is easy to compute and has properties that make it desirable to use. Coefficient alpha’s popularity has resulted in a wide breadth of research into its qualities. Notably, research about coefficient alpha’s distribution has led to developments …


Exploring The Dimensions And Dynamics Of Partnered Sexual Behaviours: Scale Development And Validation Using Factor And Network Analysis, Devinder S. Khera Aug 2023

Exploring The Dimensions And Dynamics Of Partnered Sexual Behaviours: Scale Development And Validation Using Factor And Network Analysis, Devinder S. Khera

Electronic Thesis and Dissertation Repository

Sexual behaviours are an integral part of most intimate relationships and can serve as mechanisms for building intimacy, enhancing emotional connection, and can serve as non-verbal communication to express care, love, and compassion for significant others. Sexually compatible behaviours are also associated with sexual satisfaction – something especially important given the downstream consequences of sexual satisfaction on relationship satisfaction, relationship stability, and general well-being. However, to date, no inclusive, psychometrically validated measure of partnered sexual interests and behaviours exists. Given the central role of sexual interests and behaviours in sexual satisfaction and in turn relationship quality, we sought to develop …


Evidence-Based Practices And Self-Efficacy: A Quantitative Study Of Mental Health Counselors Treating Clients With Substance Use Disorder, Carl Bastien Jun 2023

Evidence-Based Practices And Self-Efficacy: A Quantitative Study Of Mental Health Counselors Treating Clients With Substance Use Disorder, Carl Bastien

Dissertations

Substance use disorder affects a substantial number of individuals in the United States. The specific problem of this research is that it was not known to what extent their use of evidence-based practices is driven by their sense of self-efficacy. The purpose of this quantitative correlational research was to examine to what extent the use of evidence-based practices covary with a sense of self-efficacy for mental health counselors treating individuals diagnosed with a substance use disorder. The study population was 121 mental health counselors who specialized in substance use disorder treatment who completed a digital survey. The study findings did …


A Novel Examination Of None-Of-The-Above As It Influences Examinee Item Responses, Kathryn N. Thompson May 2023

A Novel Examination Of None-Of-The-Above As It Influences Examinee Item Responses, Kathryn N. Thompson

Dissertations, 2020-current

It is imperative to collect validity evidence prior to interpreting and using test scores. During the process of collecting validity evidence, test developers should consider whether test scores are contaminated by sources of extraneous information. This is referred to as construct irrelevant variance, or the “degree to which test scores are affected by processes that are extraneous to the test’s intended purpose” (AERA et al., 2014, p. 12). One possible source of construct irrelevant variance is violating item-writing guidelines, such as to “avoid the use of none-of-the-above” in multiple-choice items (Rodriguez, 2016, p. 268).

Numerous studies have been conducted with …


Using Irtrees To Account For Response Style Effects Between Item Formats, Stephanie Leroy May 2023

Using Irtrees To Account For Response Style Effects Between Item Formats, Stephanie Leroy

Masters Theses, 2020-current

Response styles are consistent person-traits that are defined as the tendency to systematically select responses unrelated to the construct being measured (Paulhus, 1991). Response styles introduce construct-irrelevant variance that distorts observed scores on a measure and biases interpretation of the data. The current study looks at midpoint response style (MRS) and extreme response style (ERS). MRS is the tendency to select the midpoint of a rating scale, while ERS is the tendency to select the endpoints of a rating scale. Previous research sought to either account for response style effects or prevemt them – the current study does both. To …


Double Dosing: Investigating The Utility Of Multiple Priming Questions On Test-Taking Motivation, Mara Mcfadden May 2023

Double Dosing: Investigating The Utility Of Multiple Priming Questions On Test-Taking Motivation, Mara Mcfadden

Masters Theses, 2020-current

Priming examinees with questions about intended effort prior to testing has been shown to significantly increase examinee expended effort via self-reported effort and response-time effort. However, this question-behavior effect seems to wear off later in a testing session, specifically when a test is given second in the session. I examined whether administering a second “dose” of the question-behavior effect could combat the decrease in examinee effort later in a testing session. To evaluate whether “double dosing” could increase examinee effort later in a testing session, I randomly assigned examinees to one of three question conditions prior to completing two low-stakes …


College-Related Stress And Substance Use: Experiences Of Honors And Non-Honors Students, Melanie Fischer May 2023

College-Related Stress And Substance Use: Experiences Of Honors And Non-Honors Students, Melanie Fischer

Undergraduate Honors Theses

Although there is a wealth of research knowledge related to risk behavior engagement of the general student population, there is less specifically reported about honors students. To address this gap in research, non-honors and honors students were surveyed to determine possible differences in risk behavior engagement. Students were recruited through the East Tennessee State University psychology subject pool and via direct email messages to an honors student-specific listserv. We hypothesized that honors students would have differences in terms of GPA and number of credit hours, endorse more substance use and have more perceived stress compared to non-honors students. The survey …


Attitudes Towards Mental Health, Spiritual Seeking, And Well-Being, David Mitchell May 2023

Attitudes Towards Mental Health, Spiritual Seeking, And Well-Being, David Mitchell

Electronic Theses and Dissertations

Religion plays a crucial role in many peoples’ lives, shaping the way they interact with the world and react to stressors. The Relational Spirituality Model (Sandage & Shults, 2007) posits that individuals’ relationship with God resembles humans’ relationships with one another. That is, relationships consist of intimacy and closeness as well as independence and time away from each other, otherwise known as dwelling and seeking. Previous literature has analyzed the relationship between spiritual coping and well-being, yet none have analyzed the relationship between spiritual seeking and overall well-being using attitudes towards mental health as a moderator. Participants were 84 undergraduate …


On The Importance Of Perceived Interpersonal Safety: Antecedents And Consequences Of Living A Subjectively Safe Life, Stylianos Syropoulos Apr 2023

On The Importance Of Perceived Interpersonal Safety: Antecedents And Consequences Of Living A Subjectively Safe Life, Stylianos Syropoulos

Doctoral Dissertations

The need to be and feel safe is a fundamental human need. Despite extensive theoretical arguments on the subject, and research on relevant concepts, empirical work on what it means to feel interpersonally safe (i.e., in the presence of others or in social environments in general) is scarce. This dissertation presents four investigations that seek to address this gap. It also seeks to highlight the consequences of feeling interpersonally safe for our mental and physical health, and to what degree healthy and high-quality close relationships influence how safe we feel. Chapter 1 is a literature review summarizing theories underlying these …


Towards Scalable Mental Health: Leveraging Digital Tools In Combination With Computational Modeling To Aid In Treatment And Assessment Of Major Depressive Disorder, Matthew D. Nemesure Mar 2023

Towards Scalable Mental Health: Leveraging Digital Tools In Combination With Computational Modeling To Aid In Treatment And Assessment Of Major Depressive Disorder, Matthew D. Nemesure

Dartmouth College Ph.D Dissertations

Major depressive disorder (MDD) is a debilitating disorder that impacts the lives of nearly 280 million individuals worldwide, representing 5% of the overall adult population. Unfortunately, these statistics have been both trending upward and are also likely an underestimate. This can be primarily attributed to lack of screening paired with a lack of providers. Worldwide, there are roughly 450 individuals living with MDD per mental health care provider. Adding to this burden, approximately half of affected individuals that do receive care of any kind will fail to remain in remission. The goal of this thesis work is to leverage statistical …


Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance Feb 2023

Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance

Dissertations

Infertility remains one of the most difficult relational contexts for couples. However, some research suggests that some couples actually increase their overall satisfaction in their relationship through infertility due to a deeply shared emotional experience. To the knowledge of the author of this dissertation, no studies exist which explain how couples arrive at their relational outcomes through the experience of infertility. These studies within this dissertation add to the present literature by explaining how couples may arrive at their relational outcome through the lens of Gottman Method Couple Therapy (GMCT). For both studies presented here, 902 participants were recruited through …


Using Bayesian Generalized Structural Equation Modeling To Analyze Latent Agreement, Sydne T. Mccluskey Feb 2023

Using Bayesian Generalized Structural Equation Modeling To Analyze Latent Agreement, Sydne T. Mccluskey

Dissertations, Theses, and Capstone Projects

Rater comparison analysis is commonly necessary in the social sciences. Conventional approaches to the problem generally focus on calculation of agreement statistics, which provide useful but incomplete information about rater agreement. Importantly, one-number agreement statistics give no indication regarding the nature of disagreements, nor do they distinguish between agreement on presence versus absence of a state or trait. Latent variable models can address both problems, as well as overcoming other well-documented limitations of agreement statistics (e.g., sample dependence, inappropriate population assumptions). Whether raters exactly agree is usually not the question of interest – researchers almost never care whether the difference …


Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel Jan 2023

Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel

Theses and Dissertations (Comprehensive)

There are myriad methods offered in the “self-help industry” and on social media promising to improve happiness. Some messages are evidence-based, often drawn from positive psychology research, and suggest actions requiring time and effort, while other messages may offer feel-good platitudes that are devoid of meaningful guidance; we label this latter type of content “inspirational bullshit.” Across two manuscripts, we investigate the predictors of liking different kinds of positive self-help content, from meaningless randomly-generated phrases to vacuous positivity to evidence-based advice. In the first manuscript, across three studies, bullshit receptivity (a tendency to judge pseudo-profound statements as profound) and people’s …

The objective of this research is to search for and recognize patterns from the content of some of the top journal articles in the field of industrial and organizational psychology. The information gained from analyzing the content of the …


Does Cleft Repair Surgery Restore Normal Visual And Neural Responses To Infant Faces?, Rachael Leanne Kee Jan 2023

Does Cleft Repair Surgery Restore Normal Visual And Neural Responses To Infant Faces?, Rachael Leanne Kee

Cal Poly Humboldt theses and projects

Infant faces readily capture our attention and elicit enhanced neural processing, likely due to their evolutionary importance in facilitating bonds with caregivers. Infant facial malformations are associated with a lower degree of parental investment and have been shown to negatively impact early infant-caregiver interactions. Cleft lip or cleft palate is a common facial malformation, estimated to affect 1 in 700 live births worldwide, that is associated with altered visual and neural processing as compared to normal infant faces. Importantly, it is not yet known how craniofacial repair surgery impacts responses to these faces. The current study uses eye tracking and …


Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber Jan 2023

Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber

Cal Poly Humboldt theses and projects

This study aimed to investigate the potential impact of negative social media content on athletes' cortisol levels and subsequent performance. The study focused on the change in cortisol levels and differences in free throw performance, based on previous research findings. We hypothesized that negative social media postings would increase the stress experienced by student-athletes, resulting in elevated cortisol levels and decreased performance. Additionally, participants (n = 8) completed a questionnaire to examine the interaction between preexisting fear and the biological stress response. Contrary to expectations, there was no significant change in stress response, and negative postings did not have …


Construction And Use Of Cognitive Maps In Model-Based Control, Ata Karagoz Dec 2022

Construction And Use Of Cognitive Maps In Model-Based Control, Ata Karagoz

Arts & Sciences Electronic Theses and Dissertations

When making decisions, we sometimes rely on habit and at other times plan towards goals. Planning requires the construction and use of an internal representation of the environment, a cognitive map. How are these maps constructed, and how do they guide goal-directed decisions? We coupled a sequential decision-making task with a behavioral representational similarity analysis approach to examine how relationships between choice options change when people build a cognitive map of the task structure. We found that participants who encoded stronger higher-order relationships among choice options showed increased planning and better performance. These higher-order relationships were more strongly encoded among …


Thematic Consistency Between Criminal History And Crime Scene Behaviors: Comparing Sexual Homicide Offenders With And Without Criminal Histories Of Sexual Offenses, Shannon E. Ettinger Dec 2022

Thematic Consistency Between Criminal History And Crime Scene Behaviors: Comparing Sexual Homicide Offenders With And Without Criminal Histories Of Sexual Offenses, Shannon E. Ettinger

Student Theses

Offender profiling research suggests that offenders may display behavioral consistency, meaning they may behave in some consistent manner between their crime scene actions and other aspects of their lives. Through behavioral themes, researchers can identify consistency in groups of individual behaviors that are thematically similar. Previous literature successfully applied the Expressive/Instrumental themes to homicide crime scene behaviors and criminal history. The current study aims to apply the Expressive/Instrumental thematic approach to analyzing the relationship between sexual homicide offender’s criminal history and their crime scene behaviors. The present study focuses on the distinction between sexual homicide offenders with a history of …


An Investigation Of Lab-Based Research Procedural Fidelity: The Relationship Between Experimenter Infant-Directed Speech, Temperament And Language Proficiency, Tess A. Simpson Dec 2022

An Investigation Of Lab-Based Research Procedural Fidelity: The Relationship Between Experimenter Infant-Directed Speech, Temperament And Language Proficiency, Tess A. Simpson

Electronic Theses and Dissertations

The purpose of the present study was to investigate whether developmental researchers were influenced in the laboratory by the characteristics of children who participate in their research. I hypothesized that experimenters, as social partners, would adapt their speaking and other behaviors to the child’s perceived temperamental profile and language proficiency. I specifically focused on whether experimenters would adhere to the experimental laboratory procedure of two elicited imitation tasks, Feed Bear and Make a Rattle, in an archival dataset. Participants included 61 primarily white 15-month-olds. Coders transcribed infant directed speech (IDS) and analyzed transcriptions for total words, words per sentence, and …


Beyond The Numbers: A Deeper Dive Into The Dearth Of Girls And Women In Stem, Jennifer John Buck Dec 2022

Beyond The Numbers: A Deeper Dive Into The Dearth Of Girls And Women In Stem, Jennifer John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite decades of research attempting to better understand the dearth of girls and women in science, technology, engineering, and math (STEM), gender imbalances persist in many STEM fields. This is particularly the case in math-intensive STEM fields. The current program of research used mixed-methods research to better understand these inequities. The first paper identified gender and ethnic variation in how undergraduates reason about STEM inequities. The second paper found that how emerging adults narrate “turning points” in their relationship with math was associated with their current math outcomes and future plans to pursue math. The final paper demonstrated that how …


Towards More Task-Generalized And Explainable Ai Through Psychometrics, Alec Braynen Nov 2022

Towards More Task-Generalized And Explainable Ai Through Psychometrics, Alec Braynen

USF Tampa Graduate Theses and Dissertations

In this work, we propose that adopting the methods, principles, and guidelines of the field of psychometrics can help the Artificial Intelligence (AI) community to build more task-generalizable and explainable AI. Three arguments are presented and explored. These arguments are that psychometrics can help by providing 1) a framework for formulating better datasets, 2) psychometric AI data that can lead to models of generalization in AI, and 3) explainable AI through more informative evaluations.

A review of psychometrics and psychological generalization is performed, along with an overview of evaluation, generalization, and explainability in AI. Various ideas are presented throughout for …
