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...
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....
The role of providing care for a loved one with Alzheimer’s disease can expose friends and family caregivers to significant stress over an extended period of time, resulting in a host of negative outcomes like increased depression and anxiety, and diminished quality of life. However, previous studies have found that...
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...
Anxiety and depression are highly prevalent, recurrent, and major public health problems. Decades of research has uncovered associations between symptom dimensions of anxiety and depression and abnormal neural activation across executive control-, threat-, and reward-related networks. Recent studies have developed a hierarchical symptom structure of anxiety and depression termed the...
This thesis focuses on the development of a cochlear implant (CI) that uses photons to stimulate surviving auditory neurons in severe-to-profoundly deaf individuals. The benefit of optical over electrical stimulation is its spatial selectivity with the potential to create significantly more independent channels to encode acoustic information and likely enhances...
People are exposed to inaccurate claims and ideas every day, from sources intended to inform, entertain, or do both. A large body of research has demonstrated that exposure to inaccurate statements, even when conveying obviously false ideas, can affect people’s subsequent judgments. Contemporary accounts suggest that these effects may be...
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...
Orienting attention enables us to select, process, and react to relevant objects in complex environments. Just as we can orient attention in space and to certain object features, recent research has shown that we can also orient attention in time (temporal orienting). This dissertation investigates the mechanisms and the effects...
Exposure to violence, which includes child abuse, neglect, witnessing domestic or community violence, crime, and sexual assault, is a national concern. Over the course of a year, 68% of children under age 17 are exposed to at least one form of violence (Finkelhor, Turner, Shattuck, & Hamby, 2015). Young children...
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...
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...
Difficulties in prosody (e.g., intonation, volume, rate), turn-taking, and overly formal speech constitute common social communication deficits in autism spectrum disorder (ASD), which can significantly hinder social interactions (Paul et al., 2009). Subtle parallel differences in social communication have also been noted in parents of individuals with ASD, suggesting that...
The overall goal of this dissertation, comprised of three empirical studies, was to examine the role of social support as a source of resilience in the face of two chronic stressors: low socioeconomic status and first-generation college student status. Study 1 of this dissertation sought to examine neighborhood support from...
Conversation is an important part of human life. Given globalization and the numerous languages around the world, it is increasingly likely that we will be communicating with others speaking in their second language (L2) rather than their first language (L1). In these situations, communication may require more effort. However, people...
The advent of advanced computing and AI has led to social technologies becoming agentic teammates in human-autonomy teams. Interpersonal trust, vital for team functioning, is crucial in determining these teams' success or failure. Trust, while essential, can be easily broken and requires maintenance and repair. This dissertation addresses two questions:...
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...
This dissertation investigates the relationship between melancholy and the development of American and Iranian literary discourses as responses to the crisis of postwar sovereignty. While situating itself against the complicated backdrop of US/Iran relations since the Second World War, it explores the impact of religion on the formation of political...
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...
