β-amyloid (Aβ) plaques and tau-related neurodegeneration are pathologic hallmarks of Alzheimer’s disease (AD). The utility of AD biomarkers, including those measured in cerebrospinal fluid (CSF), in predicting future AD risk and cognitive decline is still being refined. Here, we explored potential relationships between functional connectivity (FC) patterns within the default-mode network (DMN), age, CSF biomarkers (Aβ₄₂ and pTau₁₈₁), and cognitive status in older adults. Multiple measures of FC were explored, including a novel time series-based measure [total interdependence (TI)]. In our sample of 27 cognitively normal older adults, no significant associations were found between levels of Aβ …

Theory-Driven Longitudinal Study Exploring Indoor Tanning Initiation In Teens Using A Person-Centered Approach, Joel J. Hillhouse, Rob Turrisi, Michael J. Cleveland, Nichole M. Scaglione, Katie Baker, L. Carter Florence

ETSU Faculty Works

Background

Younger indoor tanning initiation leads to greater melanoma risk due to more frequent and persistent behavior. Despite this, there are no published studies exploring the predictors of indoor tanning initiation in teen populations.

Purpose

This longitudinal study uses latent profile analysis to examine indoor tanning initiation in indoor tanning risk subgroups from a national sample of female adolescents.

Methods

Latent profile analysis used indoor tanning beliefs and perceptions to identify indoor tanning initiation risk subgroups. The teens in each subgroup were reassessed on indoor tanning initiation after a year.

Results

Three subgroups were identified: a low risk, anti-tanning subgroup …

Brain Responses To Biological Motion Predict Treatment Outcome In Young Children With Autism, D. Yang, Kevin Pelphrey, D. Sukholdolsky, M. Crowley, E. Dayan, +6 Additional Authors

Pharmacology and Physiology Faculty Publications

Autism spectrum disorders (ASDs) are common yet complex neurodevelopmental disorders, characterized by social, communication and behavioral deficits. Behavioral interventions have shown favorable results—however, the promise of precision medicine in ASD is hampered by a lack of sensitive, objective neurobiological markers (neurobiomarkers) to identify subgroups of young children likely to respond to specific treatments. Such neurobiomarkers are essential because early childhood provides a sensitive window of opportunity for intervention, while unsuccessful intervention is costly to children, families and society. In young children with ASD, we show that functional magnetic resonance imaging-based stratification neurobiomarkers accurately predict responses to an evidence-based behavioral treatment—pivotal …

Rapid Cortisol And Testosterone Responses To Sex-Linked Stressors: Implications For The Tend-And-Befriend Hypothesis, Jennifer Byrd-Craven, Jessica L. Calvi, Shelia M. Kennison

Center for Brain, Biology, and Behavior: Faculty Publications

Current evolutionary theories regarding the nature of hormonal responses to a variety of salient social stimuli are incomplete in yielding evidentiary support for their assertions. This study offers more nuanced evidence for the Tend-and- Befriend model of sex differences in responses to social stimuli. Participants were randomly assigned to a mortality salience prime or a control condition prior to viewing a video of an out-group threat or a video of infants crying. Cortisol and testosterone responses were assessed. The results showed that in mortality salience conditions, females showed significantly higher cortisol responses to infants crying compared to males. Further, in …

Neural Processing Of Emotional Musical And Nonmusical Stimuli In Depression, Rebecca J. Lepping, Ruth Ann Atchley, Evangelia Chrysikou, Laura E. Martin, Alicia A. Clair, Rick E. Ingram, W. Kyle Simmons, Cary R. Savage

Center for Brain, Biology, and Behavior: Faculty Publications

Background Anterior cingulate cortex (ACC) and striatum are part of the emotional neural circuitry implicated in major depressive disorder (MDD). Music is often used for emotion regulation, and pleasurable music listening activates the dopaminergic system in the brain, including the ACC. The present study uses functional MRI (fMRI) and an emotional nonmusical and musical stimuli paradigm to examine how neural processing of emotionally provocative auditory stimuli is altered within the ACC and striatum in depression.

Method Nineteen MDD and 20 never-depressed (ND) control participants listened to standardized positive and negative emotional musical and nonmusical stimuli during fMRI scanning and gave …

The Relationship Between Physical Fitness And School Performance In Middle School Girls, Jamie Anne Donnelly

Walden Dissertations and Doctoral Studies

Past research has indicated a significant relationship between physical fitness and standardized test scores; however, the relationship between physical fitness and other aspects of school performance has yet to be empirically examined in a population specifically composed of middle school girls. This study examined several factors that contribute to school success, such as classroom behavior, attendance, and grades, in relation to physical fitness among a group of adolescent girls. It was specifically designed to examine the statistical relationship between physical fitness, as measured by the Fitnessgram, and quantitative data on school performance including grades, standardized test scores, school behavior, and …

Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard

Theses and Dissertations--Gerontology

Homeodynamic space (HDS) shrinks as vulnerability increases with aging and repeated damage to the cells. HDS is lost in alcoholic pancreatitis patients due to overconsumption of alcohol, smoking, and high fat diets. Etiologically relevant animal models for study of chronic pancreatitis (CP) are needed. In order to begin filling this gap a central purpose of this dissertation research was to examine relationships between the alcohol and high fat diet (AHF) and pancreatitis with attention to hypersensitivity and anxiety-like behaviors. The AHF diet induced pancreatitis described here etiologically mimics human risk factors of AHF consumption for advancement to alcoholic CP.

An Integrative Neurological Model For Basic Observable Human Behavior, Ryan M. Francis

Calvert Undergraduate Research Awards

The scientific method uncovers information from the natural world in small increments. This spurs the design of models to explain how the pieces fit together and to identify future targets of research. This is especially the case in psychology, where visualizing concepts is an advantageous practice. One all too common criticism of cognitive and behavioral models in psychology is the lack of a biological basis. This paper aims to alleviate part of this issue by integrating currently understood biological and neurological mechanisms that drive psychological phenomena into a predictive and descriptive model for basic human behavior. To accomplish this task, …

Improving The Inference Of Some Experiemtal Studies By Using Ranked Auxiliary Covariates, Rajai Jabrah

College of Graduate Studies: Theses & Dissertations

In many studies, the measurement of sampling units according to the response variable is costly or time consuming, however, it is possible to rank sampling units according to baseline auxiliary covariates, which are available, easily obtainable, and cost efficient. In these cases, when estimating the population mean, Ranked Set Sampling (RSS) can be a more efficient sampling method than the Simple Random Sampling (SRS) method. In this dissertation, we propose a modified approach of the RSS method to allocate units into an experimental study, aimed to compare two or more groups.

Ranked auxiliary covariates, which are typically correlated with the …

Dualism, Physicalism, And Professional Or Alternative Health Seeking: A Gendered Perspective, Taylor M. Caldwell

Pitzer Senior Theses

Evidence supporting a range of 6-14 years between mental illness symptom recognition and psychological help seeking has spurred a substantial interest in help seeking barriers. The present study suggests that mind and body dualism, the perceiving of the mind as an entity distinct from the body, is one such barrier to help seeking. Despite the fact that beliefs in mind-body dualism or its opposite, that of physicalism, are evident in virtually all human cultures and religions, surprisingly little is known about the psychological and behavioral implications of holding such beliefs. An exception to this disparity is a study that demonstrated …

Perceived Threat Associated With Police Officers And Black Men Predicts Support For Policing Policy Reform, Allison L. Skinner, Ingrid J. Haas

Center for Brain, Biology, and Behavior: Faculty Publications

Racial disparities in policing and recent high-profile incidents resulting in the deaths of Black men have ignited a national debate on policing policies. Given evidence that both police officers and Black men may be associated with threat, we examined the impact of perceived threat on support for reformed policing policies. Across three studies we found correlational evidence that perceiving police officers as threatening predicts increased support for reformed policing practices (e.g., limiting the use of lethal force and matching police force demographics to those of the community). In contrast, perceiving Black men as threatening predicted reduced support for policing policy …

Evaluation Of A Diabetes Self-Management Program For Hispanics In Lexington Kentucky: A Pilot Study, Miguel A. Gamboa Oropeza

Theses and Dissertations--Nutrition and Food Systems

Hispanics are more affected by diabetes than non-Hispanic whites and they tend to experience more severe complications. Research shows that although self-management is poor among ethnic minorities, it is even more so among Hispanics. The “Taking Ownership of Your Diabetes” (TOYD) program has been shown to be successful in helping individuals manage their diabetes. However, no work has been conducted with Hispanic audiences in Kentucky. TOYD program allows individuals to modify lifestyle risks and solve problems related to diabetes management. The program was translated from English to Spanish. Hispanics males and females between ages 19 to 75 years …

Perceptions Of Harm And Addiction Among Dual Users Of Cigarettes And E-Cigarettes, Julia S. Rozman

Undergraduate Research Posters

Background: Tobacco harm perceptions are important factors in why individuals may initiate, substitute, and/or engage in dual or poly-tobacco use patterns. Identifying correlates of these perceptions is important for understanding why these cognitions may exist and help provide intervention targets. The purpose of the current study was to examine perceptions of harm and addiction among a sample of cigarette and electronic cigarette (e-cigarette) users and examine whether these perceptions differ by demographics, other substance use, and tobacco use history.

Methods: The current sample consisted of 29 individuals who consented to participate in a clinical laboratory study of dual cigarette and …

Engaging Moms On Teen Indoor Tanning Through Social Media: Protocol Of A Randomized Controlled Trial, Sherry L. Pagoto, Katie Baker, Julia Griffith, Jessica L. Oleski, Ashley Palumbo, Barbara Walkosz, Joel J. Hillhouse, Kimberly L. Henry, David Buller

ETSU Faculty Works

Background: Indoor tanning elevates the risk for melanoma, which is now the most common cancer in US women aged 25-29. Public policies restricting access to indoor tanning by minors to reduce melanoma morbidity and mortality in teens are emerging. In the United States, the most common policy restricting indoor tanning in minors involves parents providing either written or in person consent for the minor to purchase a tanning visit. The effectiveness of this policy relies on parents being properly educated about the harms of indoor tanning to their children.

Objective: This randomized controlled trial will test the efficacy …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

The Effects Of A Trauma-Informed Care Training Program On Mental Health Professionals Knowledge, Skills, And Attitudes With The Smi, Angelina Pelletier

PCOM Psychology Dissertations

Trauma has been found to be highly prevalent among individuals diagnosed with SMIs. Mental health professionals have been reported to misdiagnose or avoid addressing trauma in this population. There is a need to provide information about trauma and to foster awareness among mental health professionals who are treating individuals diagnosed with SMIs. With a TIC approach, operating from a recovery-oriented philosophy, there have been interventions created to address trauma and SMIs with the aim of developing awareness about trauma and the impact it may have on someone’s life. With these factors in mind, mental health professionals should be competent in …
