Medical Student Research Symposium

Mindfulness based interventions (MBI) reduce the severity of anxiety and depression among a variety of populations. While the psychological benefits of MBIs are increasingly recognized, less is known about the underlying neural correlates—particularly during childhood and adolescence, a time when many psychopathologies begin to emerge. Here, we provide the first systematic review on the neural correlates of MBI in youth. We reviewed the PubMed database for original articles examining the neural correlates of MBI in youth (0-18 years) leveraging neuroimaging. The search yielded 331 studies, of which 13 were included in the review. These studies comprised 451 participants and were …

Childhood-Onset Attention-Deficit/Hyperactivity Disorder Exacerbates Opioid Use Disorder Consequences: Mediation By Impulsive Phenotypes, Liam R. Browning, Ciara Cannoy, Tabitha E. H. Moses, Leslie H. Lundahl Phd, David M. Ledgerwood Phd, Mark K. Greenwald Phd

Medical Student Research Symposium

Background: Attention deficit hyperactivity disorder (ADHD) is highly prevalent and associated with opioid use disorder (OUD). Yet, little is known about the mechanisms by which ADHD (which is a heterogeneous construct/diagnosis) might alter the trajectory of OUD outcomes.

Aim: This cross-sectional study examines relationships between childhood ADHD (inferred as predating substance use) and the extent to which the effects of ADHD on lifetime heroin-use consequences are mediated by foreshortened time perspective and drug-use impulsivity.

Methods: Individuals who report heroin use (N=214) were screened using the Assessment of Hyperactivity and Attention (AHA), Impulsive Relapse Questionnaire (IRQ), Stanford Time Perception Inventory (STPI), …

Glutamate, And Its Relationship To Task-Induced Functional Connectivity In The Human Brain: A Focus On Schizophrenia, Kathleen Liu Young, John Kopchick, Jeffrey Stanley, Vaibhav Diwadkar

Medical Student Research Symposium

Glutamate is the brain’s major excitatory neurotransmitter mediating both neuroplasticity and network function (Zhou & Danbolt, 2014). Basal glutamate (Glu) measured using proton magnetic resonance spectroscopy (1H-MRS) provides insight into a region’s density of neuropil related to the glutamatergic system. Moreover, given the role of glutamate in mediating brain network function, Glu levels may play a role in the brain’s functional connectivity (FC), which is typically estimated from functional magnetic resonance imaging (fMRI) time series data. These questions converge when considering the clinical syndrome of schizophrenia (SCZ). Patients with SCZ show abnormalities in basal Glu in the hippocampus and prefrontal …

Norepinephrine Regulation Of Spatial Memory Using The Barnes Maze In Male And Female Rats, Serena Simpson, Ali Gheidi Phd, Nareen Sadik, Cameron J. Davidson Phd, Shane A. Perrine Phd

Medical Student Research Symposium

The role of norepinephrine (NE) in learning and memory has been extensively studied, yet its contribution remains to be clarified. This study aimed to investigate the role of NE on spatial learning and memory in female and male rats using a Barnes maze assay. We used N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4), a specific noradrenergic neurotoxin that can cross the blood brain barrier, to deplete NE stores. We hypothesized that brain NE ablation would attenuate spatial learning and memory in rats. Loss of NE by DSP-4 was determined by measuring NE (and dopamine and serotonin) levels in several brain regions using HPLC. For the …

Learning Without Contingencies Induces Higher Order Asynchrony In Brain Networks In Schizophrenia, Elizabeth L. Martin, Asadur Chowdury, Vaibhav Diwadkar, Sazid Hasan, Munajj Ul-Huq, Shahira Baajour, Dalal Khatib, Usha Rajan, Jeffrey Stanley

Medical Student Research Symposium

Schizophrenia (SCZ) is characterized by both cognitive and reward impairments. A recent study suggests that SCZ is associated with a loss of synchrony between learning and reward circuits (Robison et al., 2019) and higher levels of dis-organization of functional brain networks may underpin failures in learning that characterize SCZ (Hütt et al., 2014). Therefore, here we examined inter-group (HC ≠ SCZ) 4^th order differences in statistical regularity across a connectome of cognition and reward brain circuits. The analyses were conducted on fMRI time series data from a previous learning paradigm (Stanley et al., 2017) with periods of Encoding and …

Social Goals In Urban Physical Education: Relationships With Effort And Disruptive Behavior, Alex C. Garn, Nate Mccaughtry, Bo Shen, Jeffrey J. Martin, Mariane Fahlman

Kinesiology, Health and Sport Studies

This study investigated the relationships among four distinct types of social goals, effort, and disruptive behavior in urban physical education. Social responsibility, affiliation, recognition, status goals, along with effort and disruptive behavior in physical education were reported by high school physical education students (N = 314) from three urban schools. Findings from correlation and structural equa- tion modeling analyses revealed that social responsibility goals had a positive relationship with effort and an inverse relationship with disruptive behavior. Social status goals demonstrated a positive relationship with disruptive behavior and no relationship with effort. Social recognition goal results were mixed, as …

Motivational Profiles And Their Associations With Achievement Outcomes, Bo Shen, Nate Mccaughtry, Jeffrey J. Martin, Mariane Fahlman

Kinesiology, Health and Sport Studies

With the belief that theoretical integration in motivation may help us better understand motivational behavior, we designed this study to explore adolescents’ motivational profiles and their associations with knowledge acquisition, leisure-time exercise behaviors, and cardiorespiratory fitness. Middle school students from a large urban inner-city school district (N = 603, ages 12–14) completed questionnaires assessing motivational constructs and leisure-time exercise behavior. Knowledge and cardiorespiratory fitness were also assessed with a knowledge test and the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, respectively. Using hierarchical cluster analysis, we found that students’ motivation in physical education could be explained from a multi-theoretical …

The Theory Of Planned Behavior: Predicting Physical Activity In Mexican American Children, Jeffrey J. Martin, Kimberly L. Oliver, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Theoretically grounded research on the determinants of Mexican American children's physical activity and related psychosocial variables is scarce. Thus, the purpose of our investigation was to evaluate the ability of the theory of planned behavior (TPB) to predict Mexican American children's self-reported moderate-to-vigorous physical activity (MVPA). Children (N = 475, ages 9–12) completed questionnaires assessing the TPB constructs and MVPA. Multiple regression analyses provided moderate support for the ability of the TPB variables to predict MVPA as we accounted for between 8–9% of the variance in MVPA. Attitude, subjective norm, and perceived behavioral control accounted for 45% of the …

Determinants Of Physical Activity In An Inclusive Setting, Stephen Kodish, Pamela Hodges Kulinna, Jeffrey J. Martin, Robert Pangrazi, Paul Darst

Kinesiology, Health and Sport Studies

The purposes of this study included (a) to determine if the Theory of Planned Behavior (TPB) predicted intentions of individuals with and without disabilities to be physically active, (b) to determine if the TPB predicted behaviors of individuals with and without disabilities to be physically active, and (c) to determine if significant differences were present in physical activity opportunities between inclusive and non-inclusive elementary physical education classes taught by the same teacher. Students (N = 114, ages 10-13) completed questionnaires assessing the TPB constructs and had four days of PA evaluated through pedometer measurements. Analyses revealed that subjective norm …

Psychosocial Aspects Of Youth Disability Sport, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

Psychosocial aspects of participation in youth disability sport were examined using social-cognitive theory and the sport commitment model. An international sample of athletes with disabilities (N = 112) reported high levels of sport commitment and sport enjoyment, perceived physical ability, and sport friendship quality. They perceived their parents to provide moderately strong levels of encouragement of their sport participation. Correlational analyses indicated moderate to strong relationships among sport commitment, sport enjoyment, and perceived physical ability. Sport commitment, parental encouragement, and sport friendship quality were only somewhat related. Regression analyses indicated that enjoyment was a significant predictor (i.e., 43% of …

The Theory Of Planned Behavior: Predicting Physical Activity And Cardiorespiratory Fitness In African American Children, Jeffrey J. Martin, Pamela Hodges Kulinna, Nate Mccaughtry, Donetta Cothran, Joe Dake, Gail Frances Fahoome

Kinesiology, Health and Sport Studies

The purpose of our study was to evaluate the ability of the Theory of Planned Behavior (TPB) to predict African American children’s moderate to vigorous physical activity (MVPA) and cardiorespiratory fitness. Children (N = 548, ages 9–12) completed questionnaires assessing the TPB constructs and MVPA and then had their cardiorespiratory fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Commonly used Structural Equation Modeling fit indices suggested the model was an adequate representation for the relationships within the data. However, results also suggested an extended model which was examined and supported. Tests of direct paths from subjective …

A Social Cognitive Perspective Of Physical-Activity-Related Behavior In Physical Education, Jeffrey J. Martin, Pamela Hodges Kulinna

Kinesiology, Health and Sport Studies

The purpose of the current study was to examine student and teacher physical-activity-related behavior using the theory of planned behavior and self-efficacy theory. Although teachers reported an overwhelmingly positive attitude toward teaching physical activity lessons to promote fitness development, they only devoted 4% of their class time to actually demonstrating and promoting fitness. Students were quite sedentary during class spending 61% of class time sitting, standing, or lying down. Using hierarchical regression analyses, teachers' attitudes toward teaching physically active physical education classes accounted for 50% of the variance in teachers' intention. Teachers who demonstrated/promoted fitness and who limited their general …

The Relationships Among Competitiveness, Age And Ability In Distance Runners, Robert C. Eklund, Jeffrey J. Martin, Alan L. Smith

Kinesiology, Health and Sport Studies

The purpose of this study was to examine relationships suggested by general achievement motivation literature and the popular literature in sport using the Sport Orientation Questionnaire (SOQ). The current study examined if faster runners are more competitive than slower runners, if older athletes were less competitive than younger athletes, and if faster runners were more goal oriented than slower runners. Distance runners (n=80), ranging from 10 to 61 years old completed race packets containing a cover letter, consent forms, the SOQ and a demographic questionnaire. Runners averaged 32.9 years of age and reported levels of competitiveness and goal …
