Neurophysiological Activity Related To Speech Production: An Erp Investigation, Adithya Chandregowda

USF Tampa Graduate Theses and Dissertations

The event related potential (ERP) technique is enjoying widespread application in neurophysiological research due to its fine temporal resolution. Of relevance to this study are ERPs related to voluntary movements. The precision with which movement related processes could be recorded using the ERP technique was demonstrated by Gilden, Vaughan and Costa (1966) and Kutas and Donchin (1974, 1977, and 1980) who found that the readiness potential (RP) immediately preceding hand movement was larger over the hemisphere contralateral to the responding hand. Given that left hemisphere controls right hand movements and vice versa, their findings confirmed that the lateralized readiness potential …

An Animal Model Of Flashbulb Memory: Insights Into The Time-Dependent Mechanisms Of Memory Enhancement, Laura Ashley Bullard

USF Tampa Graduate Theses and Dissertations

The vivid memory of an emotional event, as well as memory for incidental details associated with the arousing event, has been referred to collectively as a “flashbulb memory”. An important aspect of flashbulb memory in people is that an emotional event enhances memory of contextual details, such as the weather, or clothes one was wearing at the time of the event. Therefore, an emotional event not only produces a detailed memory of the event, itself, but also enhances memory for contextual details that would otherwise not be remembered. The first goal of this work is to describe the development of …

The Effects Of Parent-Adolescent Communication And Parenting Style On The Physical Activity And Dietary Behaviors Of Latino Adolescents, Dianna Mary Boone

USF Tampa Graduate Theses and Dissertations

The obesity epidemic among children and adolescents has been growing rapidly over the past 10 years, particularly in Latino children. Multiple researchers have found support for positive associations between parent-child communication and healthy nutrition and exercise behaviors. The present study examined the relations between parent-adolescent communication and parenting style and the dietary and exercise behaviors of Latino adolescents. The study included 79 adolescents between the ages of 13 and 18 years and their parents (100% are Latino). Correlation and hierarchical regression analyses were conducted to determine which parenting style and communication variables are significantly associated with adolescents’ dietary and physical …

The Relation Between Adiposity And Anxiety In Youth: Analysis Of Peer Victimization, Teasing, Sociocultural Influences, And Internalization Of Appearance Ideals As Explanatory Variables, Natasha L. Burke

USF Tampa Graduate Theses and Dissertations

The purpose of the current study was to examine putative mediators and moderators in the association between adiposity and anxiety in a sample of overweight and obese youth. In addition, anxiety was examined as a potential moderator between adiposity and health-related quality of life (HRQOL). Participants were youth (N = 137) between 8 and 17 years old (M = 13.09, SD = 2.61) and their legal caregivers recruited from four medical clinics affiliated with the University of South Florida. Youth were primarily overweight (28.5%) or obese (64.2%) and ethnically diverse. Data were analyzed by path analysis. Weight-related teasing significantly mediated …

Effects Of Nicotine Withdrawal On Motivation, Reward Sensitivity And Reward-Learning, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Research on addictive behavior has traditionally emphasized the role that primary reinforcing effects of drugs of abuse plays in the development and maintenance of dependence. However, contemporary behavioral economic theory and animal models of nicotine dependence suggest the need for greater attention to the impact that response to alternative rewards may have on smoking behavior. The present study sought to investigate the impact of nicotine withdrawal on self-report, behavioral and neural indices of motivation, immediate response to rewards and the capacity to learn and modify behavior in response to positive and negative feedback. Heavy smokers (n = 48) completed two …

Hpv Vaccine Decision-Making Among Male Sexual Minorities: An Integrative Theoretical Framework For Vaccine Promotion, Christopher W. Wheldon

USF Tampa Graduate Theses and Dissertations

Men who have sex with men (MSM) are at increased risk of anal cancer as a result of anal HPV infection. Routine HPV vaccination is recommended for all MSM up through age 26; however, vaccine uptake among this population is low. The Integrative Model of Behavioral Prediction (IM) was used to identify, describe, and explain psychosocial factors related to HPV vaccine decision-making for young MSM. A sequential mixed-methods approach consisting of semi-structured interviews, a quantitative survey, and a qualitative open-ended survey was used to address the following aims: (1) Determine salient outcome, normative, efficacy, and control beliefs related to HPV-vaccination …

Effects Of Occupational Stressors On Nurses’ Safety Performance And Well-Being: A Within-Individual Study, Xinxuan Che

USF Tampa Graduate Theses and Dissertations

Occupational stressors have been extensively studied as predictors of safety performance and employee well-being in previous research. However, many newly introduced organizational constructs that have the characteristics of an occupational stressor have rarely been studied as such, especially from a within-person perspective. The current study focused on three occupational stressors in relation to safety performance. Based on previous literature, I proposed that within individuals, compulsory citizenship behavior, illegitimate tasks, and interpersonal conflict at work as occupational stressors would have negative effects on employees well-being and safety performance through negative emotions (anger), job attitudes (job satisfaction and organizational commitment) and role …

Undergraduate College Students’ Attitudes About Internet-Based Mental Health Interventions, Kathleen Palmer

USF Tampa Graduate Theses and Dissertations

Millennial-aged young adults, often referred to as “digital natives,” comprise the typical college-age population, and there has been a growing number college students at risk for mental health problems (Mowbray, Mandiberg, Stein, Kopels, Curlin, Megivern, Strauss, Collins & Lett, 2006; Eisenberg, Gollust, Golberstein & Hefner, 2007). Suicide is the second leading cause of death among college students (Suicide Statistics, 2014); however, their rate of utilizing mental heath counseling is decreasing. Providing the types of mental health services college students are likely to use can mitigate factors thought to impede their use (e.g., stigma, anonymity, confidentiality), as well as help improve …

Mediation And Moderation Analysis Of Nutrition, Inflammatory Biomarkers, And Cognition In Older Adults, Elizabeth Handing

USF Tampa Graduate Theses and Dissertations

Nutrition can be viewed as a modifiable factor related to maintaining and preserving health in older adults. Previous studies have found that nutritional factors can influence cognitive abilities, however few studies have examined macronutrients and micronutrients as they relate to cognitive functioning. Research has yet to examine the mechanisms related to nutrition, cognition and aging in an older adult population from a holistic and interactive perspective.

This dissertation examined three research questions to better understand the relationship between age, nutrition, cognition, and inflammatory biomarkers. First, is nutrition related to cognition beyond demographic factors? Do individual nutrients serve as mediators? Second, …
