Sexual Minority Stigma And System Justification Theory: How Changing The Status Quo Impacts Marriage And Housing Equality, Jordan A. Blenner

Department of Psychology: Dissertations, Theses, and Student Research

Sexual minorities (i.e. lesbians and gay men) experience systemic discrimination throughout the United States. Prior to the Supreme Court ruling in Obergefell v. Hodges (2015), in many states, same-sex couples could not marry and sexual minorities were not protected from sexual orientation housing discrimination (Human Rights Campaign, 2015). The current, two-experiment study applied Jost and Banaji’s (1994) System Justification Theory to marriage and housing discrimination. When sexual minorities question dissimilar treatment, thereby threatening the status quo, members of the heterosexual majority rationalize sexual minority discrimination to maintain their dominant status (Alexander, 2001; Brescoll, Uhlmann, & Newman, 2013; Citizens for Equal …

Construction Of An Anti-Mexican American Bias Scale And Its Validation, Leslie N. Martinez

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of the dissertation is to develop a meaningful measure of Anti-Mexican American attitudes and to test that measure for its utility in predicting biased attributions for Mexican Americans. Attention has mainly focused on bias against Blacks, and this has produced important gaps in the understanding of race/ethnic bias that must be addressed. For the past few decades, the number of racial minorities, especially the number of Latinos/Hispanics, has been on the rise. The psychometric properties and validation of the new Anti-Mexican American Attitude Scale (AMAAS) were investigated through study 1 and study 2. The principal components analysis pulled …

Exposure And Responses To Pre-Incident Behavior In A College Student Sample, Brandon A. Hollister

Department of Psychology: Dissertations, Theses, and Student Research

Campus threat assessment has included gathering, assessing, and intervening in situations with pre-incident behavior. However, with limited general population examination, concerns regarding the prevalence, assault correspondence, and reporting of pre-incident behavior exist. With an undergraduate student sample (n = 1,063), this dissertation utilized a survey regarding exposure and response to campus safety concerns. In comparison to students not witnessing concerns, students seeing problematic behavior had higher self-reported antisocial history and campus connectedness. Students witnessing physical assault were more likely to see multiple pre-incident behaviors, multiple incidents of pre-incident behavior, threatening statements, and threatening gestures from the perpetrator than students witnessing …

Escalating Risk And The Moderating Effect Of Resistance To Peer Influence On The P200 And Feedback-Related Negativity, John Kiat, Elizabeth Straley, Jacob Cheadle

Department of Psychology: Dissertations, Theses, and Student Research

Young people frequently socialize together in contexts that encourage risky decision making, pointing to a need for research into how susceptibility to peer influence is related to individual differences in the neural processing of decisions during sequentially escalating risk. We applied a novel analytic approach to analyze EEG activity from college-going students while they completed the Balloon Analogue Risk Task (BART), a well-established risk-taking propensity assessment. By modeling outcome-processing-related changes in the P200 and feedback-related negativity (FRN) sequentially within each BART trial as a function of pump order as an index of increasing risk, our results suggest that analyzing the …

A Comparison Between Telehealth And Face-To-Face Brief Alcohol Interventions For College Students, Sarah Christine King

Department of Psychology: Dissertations, Theses, and Student Research

Problematic alcohol use is a common occurrence among college students. While empirically supported interventions exist, their access is typically limited to those who attend large universities. In the health care field there has been an expansion of services provided via telehealth to increase client access to treatment. However, the evidence is mixed regarding the effectiveness of face-to-face versus telehealth interventions and there is a gap in the literature regarding the use of telehealth interventions for brief alcohol interventions in college students. As such, the purpose of this study was to test the effectiveness of a well-validated brief alcohol screening and …

Avoidance As An Explanatory Mechanism For Poor Outcomes In Treatment For Substance Use Disorders, Andrew Oakland

Department of Psychology: Dissertations, Theses, and Student Research

Substance use disorders (SUDs) are prevalent and lead to significant impairments in people's lives in a variety of ways. One area which has gained attention is that of SUDs and their high comorbidity with mood and anxiety disorders. Many theories exist as to why these conditions often occur together, and the self-medication hypothesis is one that has perhaps the most research and general support behind it. The self-medication hypothesis states that individuals use substances to reduce negative affect which creates a feedback loop of negative reinforcement. Individuals then develop problematic substance use in addition to emotional dysregulation. One recent theory …

Mixed-Effects Location-Scale Models For Conditionally Normally Distributed Repeated-Measures Data, Ryan Walters

Department of Psychology: Dissertations, Theses, and Student Research

Hypotheses about psychological processes are most frequently dedicated to individual mean differences, but individual differences in variability are likely to be important as well. The mixed-effects location-scale model estimates individual differences in both mean level and variability in a single model, and represents an important advance in testing variability-related hypotheses. However, the mixed-effects location-scale model remains relatively novel to empirical scientists as statistical software is often handicapped by more complex models and a paucity of methodological studies exist examining the statistical properties of this model.

This dissertation investigates the mixed-effects location-scale model through the development of open-source software for its …

Self-Protective Behaviors And Campus Threat Assessment, Sarah Hoff

Department of Psychology: Dissertations, Theses, and Student Research

Extreme acts of targeted violence on postsecondary campuses have prompted many institutions to commit more resources to increasing safety while maintaining an open and creative environment. Investigations after incidents of targeted violence on campuses have identified pre-incident behaviors, or “red flags,” that were observed before the perpetrator engaged in violence. Threat assessment is a proactive approach to preventing acts of targeted violence that was initially developed by members of the United States Secret Service (USSS), and has since expanded into the context of postsecondary campuses. Research has shown some individuals may engage in self-protective behaviors in order to reduce their …

Who’S To Blame? Blame Attributions And Obesity-Related Law And Policy, Lindsey E. Wylie

Department of Psychology: Dissertations, Theses, and Student Research

Obesity is a foremost public health concern that has received considerable attention. Because of this so-named “epidemic,” law-makers are challenged with implementing effective policies that the public supports. Little is known, however, about the antecedents and consequences of these policies—especially attributions of blameworthiness. Study 1 developed the Obesity Blame Attribution Scale (OBAS). Confirmatory factor analysis demonstrated that controllability, responsibility and dispositional blame were separate constructs and were part of a higher-order dispositional blame factor. Situational blame was a separate higher-order factor, not correlated with dispositional blame, consisting of blame toward the food industry and towards government policy. Using the OBAS, …

Premature Termination Of Outpatient Psychotherapy: Predictors, Reasons, And Outcomes, Kristin N. Anderson

Department of Psychology: Dissertations, Theses, and Student Research

Premature termination is a pervasive barrier to effective implementation of outpatient psychotherapy that frequently results in decreased treatment gains for clients and lowered morale for therapists. Unfortunately, despite its high prevalence and cost, premature termination remains poorly understood. The current study addressed some gaps in the literature using a national online survey design that permitted investigation of a broader range of potential predictors, exploration of more specific reasons for premature termination, and examination of longer term treatment outcomes than has been possible in most previous research. Participants were 278 workers from Amazon.com’s Mechanical Turk, an online labor market regularly used …

Double Dissociation Of The Anterior And Posterior Dorsomedial Caudate-Putamen In The Acquisition And Expression Of Associative Learning With The Nicotine Stimulus, Sergios Charntikov

Department of Psychology: Dissertations, Theses, and Student Research

Tobacco use is the leading cause of preventable deaths worldwide. This habit is not only debilitating to individual users but also to those around them (second-hand smoking). Nicotine is the main addictive component of tobacco products and is a moderate stimulant and a mild reinforcer. Importantly, besides its unconditional effects, nicotine also has conditioned stimulus effects that may contribute to the tenacity of the smoking habit. Because the neurobiological substrates underlying these processes are virtually unexplored, the present study investigated functional involvement of dorsomedial caudate putamen (dmCPu) in the conditioning processes with nicotine as a conditioned stimulus. Rats were trained …

Stress And Eyewitness Memory: Timing Of Stressor And Association With Cortisol Stress Responding, Timothy Ryan Robicheaux

Department of Psychology: Dissertations, Theses, and Student Research

Witnesses to and victims of criminal events can face significant stress during such encounters. Stress responding consists of a multitude of responses (e.g., anxiety, cardiovascular changes, cortisol responding). In the current study, I utilized a physiological stressor (i.e., the cold-pressor test) and a facial recognition paradigm to examine the relationship between cortisol change following stress exposure and memory accuracy. More specifically, I examined whether cortisol levels at specific memory stages (i.e., acquisition and retrieval) predicted stress responding differently.

Findings suggested that individual differences in cortisol stress responding to the cold-pressor test predicted facial recognition when peak cortisol was at a …

Parenting Young Children In Contemporary Chinese Society: A Mixed Methods Study, Lixin Ren

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of this mixed methods study was to examine contemporary Chinese parents’ childrearing expectations, goals, and practices for their preschool-aged children. Participants included 154 parents with preschool-aged children (children’s mean age was 52.48 months with a standard deviation of 6.84) and 27 teachers recruited from seven preschools located in three small cities in northeastern China. In the quantitative phase, parents completed questionnaires measuring parental expectations (social-emotional and academic expectations), parenting styles, child social competence, and child pre-academic performance. The head teacher of each target child reported the child’s social competence and pre-academic performance. It was hypothesized that parental expectations …
