A Quantitative Analysis Of The Value-Enhancing Effects Of Nicotine, Bupropion, And Varenicline In Male And Female Rats, Scott Barrett

Department of Psychology: Dissertations, Theses, and Student Research

Smoking and tobacco dependence are serious health concerns in the United States and globally. Reward via the pharmacological effects of nicotine are believed to be the principal motivating factor that drive tobacco dependence. Research reveals differences in sensitivity between males and females to the motivational effects of nicotine in tobacco use. Enhancement of reinforcement value of non-nicotine rewards contributes to overall nicotine reward. Similar value-enhancing effects have been observed by the two most commonly prescribed smoking cessation aids, bupropion and varenicline. The present dissertation investigated the value-enhancing effects of nicotine, bupropion and varenicline in both male and female rats using …

The Effect Of Yoga Lessons On Young Children's Executive Functioning, Heidi L. Beattie

Department of Psychology: Dissertations, Theses, and Student Research

Individual differences in preschool and school-aged children’s attention, inhibition and spatial working memory were examined after exposure to a yoga intervention. Previous research has found that exposure to yoga has improved attention in both adults and children. Previous research, however, is limited in regards to examining this relationship in a preschool-aged population. The purpose of the current study is to examine and compare the relationship between preschool-aged as well as school-aged children’s attention, inhibition, and spatial working memory abilities for children who participated in a yoga intervention and children who do not participate in a yoga intervention. Twenty-six 4 to …

Executive Control In Hispanic Children: Considering Linguistic And Sociocultural Factors, Miriam M. Martinez

Department of Psychology: Dissertations, Theses, and Student Research

Executive control represents a collection of high-order cognitive processes that are associated with important child outcomes, including academic achievement and social competencies. Despite the burgeoning interest in examining the development of executive control, less is known about the development of these skills among ethnic minority children. Hispanic children are currently the largest ethnic minority group in the United States and their diverse sociocultural and linguistic backgrounds provide an excellent context to study the influence of linguistic and sociocultural factors on the development of child executive control. The purpose of the three complementary studies reported in this dissertation is to contribute …

Effects Of Alcohol Intoxication And Neurocognitive Processing On Intimate Partner Aggression, Rosalita C. Maldonado

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious public health concern that occurs with alarming frequency, results in both physical and psychological harm to victims, and costs billions of dollars per year due to healthcare costs and loss of productivity. These adverse consequences highlight the need to understand risk factors of IPA perpetration. Attempts to identify these risk factors have focused mostly on broad factors that may predispose someone to perpetrate aggression, including individual demographic and dispositional characteristics (e.g., low socioeconomic status, psychopathy). Although valuable, this knowledge cannot reveal the specific circumstances that may prompt an individual to perpetrate aggression against …

Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm

Department of Psychology: Dissertations, Theses, and Student Research

This dissertation investigates the role of trust in predicting cooperation with a natural resources management institution. It begins with an exploration of the legal landscape against which the relationship between land owners and natural resources management institutions is contextualized, presents a review of the often ostensibly disparate trust literature and a framework for its integration, and proposes and tests a model of trust and cooperation in the natural resources context. The results provide mixed support for the model as proposed but confirm the importance of trust in this context and suggest implications for policy, especially the potential importance of increasing …

Event-Related Potential Correlates Of Social And Nonsocial Cognitive Processes Related To Schizotypy, Charles A. Davidson

Department of Psychology: Dissertations, Theses, and Student Research

Social cognitive, neurocognitive, and social functioning research in serious mental illness (SMI) have recently proliferated. Their synergy requires translational bridges to applied research. This project aims to develop a measurement protocol capable of measuring independent components of social cognitive and neurocognitive brain functioning. These brain processes should each vary systematically with schizotypal traits whose extremes represent core elements of psychotic disorders. The measurement technology must be affordable, efficient, and acceptable for use in clinical settings.

An ERP protocol was developed that incorporates an array of candidate measures. The stimuli consist of emotional (angry and happy), neutral, and scrambled (non-face comparison) …

The Effects Of Alcohol Intoxication And Cognitive Emotion Regulation Strategies On Lab-Based Partner Aggression, Laura E. Watkins

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious national health concern that affects an alarming number of individuals and can lead to substantial psychological and physical suffering. Situational risk factors that arise in the immediate context of IPA reflect state-like influences that trigger aggression. Because these factors are more variable and fluctuate according to the situation, they are potentially promising targets for prevention and intervention efforts (e.g., through cognitive and behavioral interventions). Within this realm, two factors in particular appear to play a prominent role in the etiology of IPA: alcohol intoxication and cognitive emotion regulation strategies. In contrast to prior …

Procedural Due Process In Modern Problem-Solving Courts: An Application Of The Asymmetric Immune Knowledge Hypothesis, Leah C. Georges

Department of Psychology: Dissertations, Theses, and Student Research

Problem-solving courts, such as drug and mental health courts, function under the model of therapeutic jurisprudence—the idea that legal policies and procedures should help and not harm clients, within the confines of the law (Winick & Wexler, 2002). Although it would seem that the lack of procedural due process in most problem-solving courts is in direct opposition to the best interests of a client, it is possible that observers find this more of a problem than do the court clients themselves. This two-experiment study applied Igou’s (2008) AIK hypothesis to problem-solving courts’ practice of sanctioning in the absence of due …
