Cognitive Ability And Ambivalence Toward Alcohol: An Examination Of Working Memory Capacity’S Influence On Drinking Behavior, Emily T. Noyes

USF Tampa Graduate Theses and Dissertations

Research stemming from dual-processing theories suggest that working memory capacity may have an important role in the ability to inhibit automatic tendencies when there is the motivation to do so (Barrett, Tugade, & Engle, 2004). Ambivalence, the simultaneous desire to engage in (approach motivation) and inhibit (avoidance motivation), often occurs with problematic behaviors like alcohol abuse. The current study sought to determine whether individual differences in working memory capacity moderate the relationship between approach, avoidance and subsequent drinking behavior in a clinical sample. A total of 66 individuals with alcohol use disorder (AUD) participated in a baseline assessment of working …

Influencing Motivation For Alcohol Through Social Bonding, Bryan Benitez

USF Tampa Graduate Theses and Dissertations

Human survival depends upon the ability to cooperate by forming affiliative social bonds. Social bonding should therefore be a powerful motivating force in practically all human decision making. Past research demonstrates that social bonding and motivation for alcohol consumption share similar psychological and neurobiological pathways. In this study, we attempted to reduce alcohol motivation by enhancing perceptions of social bonding prior to and during the hours and days when alcohol consumption was most likely. In a predominantly female college student sample, we found mixed support for our hypotheses that a novel social bonding manipulation delivered through mobile technology would satiate …

Pathways Of Embodiment: Drug Use Among Adolescents In Popay[Aacute]N Colombia, Sarah Louise Fishleder

USF Tampa Graduate Theses and Dissertations

This research examines the interrelated biological and cultural factors that determine pathways by which recreational drug use is manifest to addiction in the lives of youth aged 12-18 in Popay[aacute]n, Colombia. It utilizes existing data from mixed methods research conducted between 2004-2005 examining epidemiological risk factors, drug use, perceptions about drugs, and a biological phenomenon of the brain known as incentive salience. Perceptions and experiences related to drugs were gathered using structured methods. MDS and hierarchical plots of drug perceptions are presented in order to demonstrate the power of culture and expectation on perception and choice. Structural equation modeling was …

The Restorative Effects Of Smoking Upon Self-Control Resources, Bryan W. Heckman

USF Tampa Graduate Theses and Dissertations

Based on a model that considers self-control (SC) to be a limited resource, research suggests that diminished SC resources increase the likelihood of smoking. Yet, no study has evaluated how smoking affects SC resources. This study used a randomized, 2 x 2 crossed factorial (SC depletion manipulation X smoking manipulation), between-subjects design to test the hypothesis that smoking restores depleted SC resources. To manipulate SC depletion, half of the 132 dependent smokers were instructed to suppress their emotional reaction to a brief video depicting environmental damage (i.e., Depletion), whereas the other half were instructed to “act natural” (i.e., No Depletion) …

Effects Of A Body Image Manipulation On Smoking Motivation, Elena Nicole Lopez Khoury

USF Tampa Graduate Theses and Dissertations

Smoking is now the leading cause of preventable death and disease in women. Understanding women's motivations to smoke is important in developing effective cessation and relapse prevention programs. Previous descriptive, correlational, and quasi-experimental research has established that weight concerns and negative body image are associated with tobacco smoking, cessation, and relapse, particularly among young women. This study, building upon a previous experimental study (Lopez, Drobes, Thompson, & Brandon, 2008), examined whether activation of negative body image cognitions would produce greater urges to smoke and would affect actual smoking behavior.

A randomized 2 X 2 crossed factorial, between-subjects design (body image …

Age-Related Differences In Cocaine Place Conditioning And Cocaine-Induced Dopamine, Kimberly A. Badanich

USF Tampa Graduate Theses and Dissertations

In humans, adolescent exposure to illicit drugs predicts the onset of adult drug abuse and suggests that early drug use potentiates adolescent vulnerability to drug addiction. In experiment 1, it was hypothesized that adolescent rats would show a CPP for a low cocaine dose if in fact adolescents are more vulnerable to cocaine's rewarding effects. Place preferences were measured in early adolescent [postnatal day (PND) 35], late adolescent (PND 45) and young adult (PND 60) rats by injecting either 0, 5 or 20 mg/kg cocaine and conditioning them to environmental cues in a 2-chamber place conditioning apparatus. Significant cocaine preferences …

Effects Of Weight-Related Cues On Smoking Motivation, Elena Nicole Lopez

USF Tampa Graduate Theses and Dissertations

Smoking is now the leading cause of preventable death and disease in women. Understanding women's motivations to smoke is important in developing effective cessation and relapse prevention programs. Women, more so than men, appear to associate their smoking behavior to issues of weight. Although a general relationship between weight concerns and smoking has been found among women, a causal relationship had not been demonstrated. This study tested whether activation of negative body image cognitions would produce greater urges to smoke and whether the relationship would be moderated by trait body dissatisfaction and mediated by state body dissatisfaction.

A randomized 2 …

The Developing Nucleus Accumbens Septi: Susceptibility To Alcohol’S Effects, Rex Montgomery Philpot

USF Tampa Graduate Theses and Dissertations

The mesolimbic dopamine (DA) system has been implicated in providing the basis of pleasure, guiding the general mechanism of reinforcement as well as motivation. Support for these roles have grown from neurochemical research in the field of addiction. It is now well known that DA activity increases in the nucleus accumbens septi (NAcc) with exposure to addictive substances. Moreover, pharmacological manipulation of this system produces predictable changes in the administration of drugs of abuse, as well as natural reinforcers. This system is responsive to natural reinforcers and addiction may be the transference of routine mesolimbic function to environmental stimuli predictive …

Engaging Smokers With Schizophrenia In Treatment For Tobacco Dependence: A Brief Motivational Interviewing Intervention, Marc L. Steinberg

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine how to best motivate smokers with schizophrenia or schizoaffective disorder to seek treatment for tobacco dependence. Smokers with schizophrenia or schizoaffective disorder (N=78) were randomly assigned to receive a Motivational Interviewing, Psychoeducational, or Minimal Control intervention. A greater proportion of participants receiving the Motivational Interviewing intervention followed through on a referral for tobacco dependence treatment within one-week and one-month post-intervention. Mixed model Analyses of Variance found no differences between groups at one-week or at one-month with respect to tobacco use or motivation to quit. Within group analyses indicated that participants in the …
