Sexual orientation is conventionally understood as relative attraction to men versus women. It has recently been argued that male sexual orientation in particular can be extended to include other dimensions of sexual attraction besides gender, such as sexual maturity and location. With respect to the dimension of location, most men...
Introduction: Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction associated with reduced quality of life, increased rates of depression and anxiety, and high economic burden to society and the individual. Current behavioral interventions, which target well-known symptom exacerbating factors such as catastrophizing and gastrointestinal- specific anxiety, have demonstrated...
Selective attention enables people to focus on a small number of objects, features, or events with good resolution. Sometimes attention may also be less selective and distributed across numerous items, which allows more information to be processed at a lower resolution. The degree to which attention is more or less...
Dynamic decision-making is a complex process that relies on our ability to generate, evaluate and implement a variety of strategies. Understanding how people navigate this process is a difficult problem that requires a wide range of methodologies. This study details a combination of behavioral experiments, computational modeling, and neuroimaging that...
The concealed information test (CIT) has garnered more empirical support than other methods of recognition detection and has a firm theoretical foundation. Because it occurs involuntarily, even when recognition is denied, P300 amplitude is a robust indictor of concealed information. Although the P300-based CIT shows great promise for field use,...
Young children can sometimes acquire new vocabulary words—even property terms—through indirect learning (e.g. Carey & Bartlett, 1978). We explore two factors that contribute to this ability—perceptual alignment and linguistic contrast. We propose that spontaneous comparison processes lead children to notice key commonalities and differences that facilitate indirect property word learning....
Health literacy has been shown to be a key component of patient understanding of medical diagnoses, adherence, and self-efficacy. Limited health literacy has been associated with a number of negative outcomes— including more severe illness, increased use of emergency services, and mortality. The concept of mental health literacy has arisen...
Interactions between working memory and long term memory systems are still not well understood, as the systems have long been thought to be mostly separate. An interesting intersection of these memory systems is domain-specific expertise, whereby individuals are able to show supra-span memory for information related to the area of...
The study of employee engagement and its consequences in the workplace has gained traction in the business world over the past decade, with dramatic claims of the direct consequences of engagement including lower absenteeism, higher sales, improved productivity, and increased profitability for organizations that are more engaged (The Gallup Organization,...
Rhythmic fluctuations of electrical activity in the brain provide insights into the proposed mechanism by which we encode experiences and then maintain, forget, modify, and retrieve them. Yet there is still much to learn about how neural oscillations relate to memory function. The purpose of this research is to discover...
This dissertation examines caregiving contexts in early childhood. Specifically, I look at how caregiving contexts are related to or influenced by other caregiving contexts and broader social contexts. The dissertation is composed of an introductory chapter that provides a theoretical overview and summary of the dissertation followed by two additional...
Speech recognition in complex acoustic environments is dependent on myriad bottom-up (i.e., peripheral) and top-down (i.e., central) processes. While bottom-up processes remain fairly stable during childhood, the development of top-down processes persists into young adulthood. The immaturity of top-down processes places younger children at considerable risk for poorer speech recognition...
Interpersonal hierarchies are one of the most fundamental structures by which human interactions are organized (Yu & Kilduff, 2019), and dual-strategies theory suggests that humans navigate these hierarchies through the use of dominance (force and coercion) or prestige (display of valued traits to gain respect; Maner & Case, 2016). In...
Stories and fantasy represent an important aspect of consumer life and comprise a huge marketing enterprise within consumer entertainment. Each year, upwards of $82 billion is spent on books, games, and other fantasy industries in the United States alone. Likewise, fantasy has important implications for consumers’ sense of identity. In...
A greater number of strategies in one’s coping repertoire (i.e., the number of diverse strategies used across stressors or use habitually across several situations) may be beneficial and a precursor to coping flexibly across situations (Bonnano & Burton, 2013). Indeed, previous studies have demonstrated a benefit of having larger number...
This dissertation investigates two ways in which personality psychology should move beyond the traditional approach of measuring personality with broad domains composed of trait descriptors, as exemplified by the Big Five taxonomy. The first study (Chapter 2) suggests an alternative to the traditional approach of aggregating personality items into domains....
Women living with human immunodeficiency virus (WLWH) have unique health challenges. Understanding psychological strengths that help WLWH manage their disease and improve health outcomes could reduce disease burden. Although spirituality, a multidimensional construct that includes a search for meaning and purpose, connection with a higher dimension, and experiences and feelings...
How do people make meaning of risk-taking? The present dissertation proposes a normative lay theory of risk-taking. The proposed model promotes the following core ideas: (a) Risk-taking is generally an ambiguous construct and requires the illumination of at least some dimensional parameters to disambiguate the risk behavior and risk-taker; (b)...
Competitive gaming, or esports, is a high-skill endeavor embedded in a highly gendered social context. Using multiple methodological approaches, this dissertation argues that gender-gaming inequality is a result of changeable stereotypes that impact women throughout their lives. Specifically, gender-gaming stereotypes limit women’s initial access to gaming, discourage their continued interest...
Background. Rates of common bacterial sexually transmitted infections (STIs) are at an all-timereported high in the United States, while rates of new human immunodeficiency virus (HIV)
infections are declining. Among HIV-negative men and transgender women who have sex with
men, whom are theoretically at risk for both HIV and bacterial...
