Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …

Genetic Taster Status As A Mediator Of Neural Activity And Swallowing Mechanics In Healthy Adults, Angela M. Dietsch, Ross M. Westemeyer, William G. Pearson Jr., Douglas H. Schultz

Center for Brain, Biology, and Behavior: Faculty Publications

As part of a larger study examining relationships between taste properties and swallowing, we assessed the influence of genetic taster status (GTS) on measures of brain activity and swallowing physiology during taste stimulation in healthy men and women. Twenty-one participants underwent videofluoroscopic swallowing study (VFSS) and functional magnetic resonance imaging (fMRI) during trials of high-intensity taste stimuli. The precisely formulated mixtures included sour, sweet-sour, lemon, and orange taste profiles and unflavored controls. Swallowing physiology was characterized via computational analysis of swallowing mechanics plus other kinematic and temporal measures, all extracted from VFSS recordings. Whole-brain analysis of fMRI data assessed blood …

Human Adaptability For Deep Space Missions: An Exploratory Study, Paul T. Bartone, Robert R. Roland, Jocelyn V. Bartone, Gerald P. Krueger, Albert A. Sciarretta, Bjorn Helge Johnsen

Journal of Human Performance in Extreme Environments

The present qualitative study conducts in-depth interviews with astronauts and other subject matter experts in order to shed light on human adaptability in extreme environments. Deep space travel will entail a range of highly stressful conditions to which astronauts must adapt. Feelings of isolation will be increased, as the space traveler is farther from Earth for longer periods of time. Daily life will take place in small and confined areas, for durations extending into years. The dangers of the extreme environment of space are ever-present, and failure of critical equipment or components can lead to death. Astronauts will need to …

Turn That Frown Upside-Down! The Effectiveness Of Opposite Action In Changing Emotion, Kaitlyn Diane Chamberlain

Graduate Theses and Dissertations

While research demonstrates that opposite action (OA) impacts emotion (Rizvi & Linehan, 2005), we lack an understanding of the mechanisms by which it produces opposite emotions. The current study dismantled emotion regulation skill components by comparing tasks with different combinations of cognitive, emotive and behavioral components. I predicted that the OA condition would be the most effective in altering negative emotion. University students (n = 194) completed a sadness induction and were randomly assigned to either a (1) control, (2) low arousal positive imagery (3) high arousal positive imagery, or (4) OA plus high arousal positive imagery condition. The control …

Social Anxiety Reduction In The Context Of Social Modeling Utilizing A Placebo Alcohol Beverage, Kyle K. Jackson

Graduate Theses and Dissertations

Alcohol misuse and elevated social anxiety are found to be highly comorbid, and being exposed to social models consuming alcohol can increase one’s consumption. Yet no research has thus far examined whether the internal experience of alcohol consumption (e.g., social anxiety reduction) can also be transmitted via social modeling. This bar-lab study examined the impact of social modeling behavioral cues of social anxiety on emerging adult drinkers. It was hypothesized that those exposed to a social model experiencing an apparent social anxiety reduction from drinking would themselves report lessened state social anxiety following a placebo drink, and that this effect …

The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations and Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …

Using Education To Increase Compliance With Heart Failure Medications, Kara Stout Do, Isaac Navarro Dmd

• Non-compliant patients are two times more likely to be readmitted to the hospital and have a three times higher mortality rate.

Somatic Symptom And Related Disorders: A Case Of Illness Anxiety Disorder In A Young Relatively Treatment Naive African American Male, Linda Zhang, Richard P. Leggett, Harrison Ross Galicki, William B. Dehart

Psychiatry

Somatic symptom and related disorders (including illness anxiety disorder and somatic symptom disorder) is a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) replacing somatoform and related disorders in the DSM-4 Text Revision. This classification eliminated the requirement that somatic symptoms must be nonorganic in nature, in an effort to reliably detect more cases of significant health anxiety than previously with DSM-4 criteria. Illness anxiety disorder is a primary anxiety disorder characterized by persistent preoccupation or excessive concern about having or developing an undiagnosed disease despite medical evaluation and reassurance. It is considered a …

Implementing Screening To Assess Readiness To Change In Overweight And Obese Patients At A Patient-Centered Medical Home, Jarrod Gant

Doctoral Projects

Obesity is at epidemic levels within the United States (U.S.), but the Southern U.S. has some of the most obese states. Mississippi (MS) is the most obese state in the country (Robert Wood Johnson Foundation, 2018). Factors such as diet, sedentary lifestyle, cultural influences, and socioeconomic status contribute to the state’s citizens being overweight and obese.

Contributing to the state’s obesity is the fact that MS has more people living in poverty than any other state (Center for American Progress [CAP], 2018). Lacking the ability to afford healthy foods and the ability to afford quality healthcare adds to the state’s …

The Importance Of Shared Language In Rural Behavioral Health Interventions: An Exploratory Linguistic Analysis, Michele Staton, Jennifer Cramer, Robert Walker, Claire Snell-Rood, Athena Kheibari

Behavioral Science Faculty Publications

A focus on the use of shared language to enhance congruence in interventionist-client dialogue is missing from traditional research on evidence-based practices and rural behavioral health. This study incorporates qualitative interactional sociolinguistics, which includes discourse analysis (typically written or audio recordings of face-to-face encounters with 11 clients and a study interventionist), to describe those speech patterns in a broad sense (dialect), as well as more specific use of communicative strategies to increase parity in the interaction between a rural interventionist delivering an evidence-based practice in the context of a research study with rural women opioid users in a non-therapeutic context. …

Behavioral And Immunohistochemical Characterization Of Rapid Reconditioning Following Extinction Of Contextual Fear, Amy R. Williams, Earnest S. Kim, K Matthews Lattal

Faculty Publications - Psychology Department

A fundamental property of extinction is that the behavior that is suppressed during extinction can be unmasked through a number of postextinction procedures. Of the commonly studied unmasking procedures (spontaneous recovery, reinstatement, contextual renewal, and rapid reacquisition), rapid reacquisition is the only approach that allows a direct comparison between the impact of a conditioning trial before or after extinction. Thus, it provides an opportunity to evaluate the ways in which extinction changes a subsequent learning experience. In five experiments, we investigate the behavioral and neurobiological mechanisms of postextinction reconditioning. We show that rapid reconditioning of unsignaled contextual fear after extinction …

A Comparison Of Opioid Abuse Screening Tools Of Detection Of High Risk Patients In The Inpatient Setting, Grace Gu Md, Albert Cheng Md, Darren Rahaman Md, Shyh-Jeun Wang Md, Maureen Strohm Md, Napatkamon Ayutyanont

Family Medicine

• The United States is currently experiencing an opioid epidemic, which claims 115 lives daily by overdose.
• Tools for identifying patients at increased risk for abuse include: Screener and Opioid Assessment for Patients with Pain (SOAPP-R) and Opioid Risk Tool (ORT).
• However, data is lacking for the comparison of the two most commonly used opioid screen tools (SOAPP-R and ORT).
• We are comparing the effectiveness of these screening tools for patients being discharged from the hospital who have no "red flags" for abuse.

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …

A Controlled Examination Of Motivational Strategies: Reviewing Positive Consequences For Goal Achievement, Negative Consequences For Undesired Behavior, And A Relaxation Exercise, Yulia Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Motivation is an integral part of human life and one of the most fundamental aspects of behavior change. Of interest to the present study are two motivational approaches, Negative Consequences Review (NCR) and Positive Consequences Review (PCR). NCR is an intervention component originally designed as part of Family Behavior Therapy (FBT) to motivate individuals with their goals through a discussion of negative consequences associated with undesired behaviors. PCR was developed as an auxiliary component of FBT to inspire individuals’ motivation to achieve their goals through a discussion about positive consequences of reaching goals. Purpose: The purpose of this study …
