Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Exercise Differences, Karissa Dold Jan 2013

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Exercise Differences, Karissa Dold

Calvert Undergraduate Research Awards

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …


An Acute Inflammatory Response In A Diabetic Alzheimer’S Disease Model, Krystal Courtney D. Belmonte, Jefferson Kinney Jan 2013

An Acute Inflammatory Response In A Diabetic Alzheimer’S Disease Model, Krystal Courtney D. Belmonte, Jefferson Kinney

McNair Poster Presentations

Alzheimer’s disease (AD) is the most common form of dementia, accounting for 50 to 80 percent of all dementia cases. This neurodegenerative disease leads to neuronal death and tissue loss in the brain, resulting in the slow deterioration of memory, thinking skills, and eventually even the ability perform daily tasks. While it is not a normal part of aging, AD is mostly diagnosed in people over the age of 65; thus, the main risk factor for Alzheimer’s disease is increased age, though it is most likely other additional factors also contribute (Heese & Akatsu, 2006). Neuropathological hallmarks of AD include …


Attention Deficit Disorder In Adults, Nutritional Deficiencies, And The Treatments Available: A Literature Review, Emilee S. Manthey Jan 2013

Attention Deficit Disorder In Adults, Nutritional Deficiencies, And The Treatments Available: A Literature Review, Emilee S. Manthey

Modern Psychological Studies

The prevalence of attention deficit hyperactive disorder (ADHD) in adults has steadily increased within the past decade. However, very few people are aware they have this disorder. Those with ADHD have higher divorce rates, school dropout rates, job termination, car accidents, and higher rates of substance abuse and alcohol dependence (Kates, 2005; Tcheremissine & Lieving, 2009). A high comorbidity rate with ADHD, anxiety, and depression has been found. This literature review includes the significant nutritional deficiencies such as neurotransmitters, trace minerals, omega-3 fatty acids, and several B vitamins which are found in people with ADHD, and a description of the …


Distress Tolerance And Mental Health Outcomes, Carrie A. Stemke Jan 2013

Distress Tolerance And Mental Health Outcomes, Carrie A. Stemke

Modern Psychological Studies

This literature review has compiled research on two related subjects: the construct of distress tolerance and the treatment of mental health issues for which low distress tolerance is an underlying factor. The purpose of this work is to not only examine a central mechanism in the onset and maintenance of select psychopathologies, but also to examine ways in which treatment focused on raising an individual's distress tolerance can help in symptom reduction. This review also proposes that a better understanding of stress and an individual's reaction to it can lead to both more effective treatment and towards the future fulfillment …


The Effects Of The Cold Pressor Task On Memory Recall, Hayden Lemer Jan 2013

The Effects Of The Cold Pressor Task On Memory Recall, Hayden Lemer

Modern Psychological Studies

Neurotransmitters that are released in response to stress can disrupt the prefrontal cortex creating an impairing effect on attentional processes leading to a hindering of memory recall (Arnsten, 2009). Participants were taken from an Intro to Psychology course from a small liberal arts college in Northeastern Pennsylvania. Participants immersed their hand in either ice-cold or warm water while listening to 20 nouns. In this present study, participants showed memory recall impairment after they received stress induced from the cold pressor task only during learning, and after a short delay consisting of a short distracter math test.


The Victorious Christian Life: Overcoming Alcohol Dependence Through The Phenomenon Of Christian Spirituality, Michael Byrne Jan 2013

The Victorious Christian Life: Overcoming Alcohol Dependence Through The Phenomenon Of Christian Spirituality, Michael Byrne

Doctoral Dissertations and Projects

Interviews were conducted with graduates of a northeastern evangelical Christian-based treatment program to discover insights regarding the role that the phenomenon of Christian spirituality played in their recovery. Eight themes were extracted from three periods of time in the participants' lives as they related to the phenomenon of Christian spirituality: prior to treatment; during treatment; and after treatment. These themes revealed that the participants lacked resiliencies to overcome alcohol dependence themselves. All participants reported that critical aspects of Christian spirituality, such as regeneration and cultivation of a divine-human relationship through lifestyle exercise of Spiritual Disciplines and diligent application of the …


Applying A Mixed Methods Approach To Understanding And Evaluating The Effects Of Family Treatment Among Sexually Abusive Youth, Jamie R. Yoder Jan 2013

Applying A Mixed Methods Approach To Understanding And Evaluating The Effects Of Family Treatment Among Sexually Abusive Youth, Jamie R. Yoder

Electronic Theses and Dissertations

Families are frequently identified as a risk for supporting and perpetuating sexually abusive behavior among youth. Traditionally, the field has focused on deficits of families rather than considering them as a resource to promote change. Although emerging literature strongly argues the need to target families in the healing process, treatment initiatives rarely follow suite, and research has failed to comprehensively document the effectiveness of family-inclusive treatment. Knowing there are several gaps in literature, the current study was conducted to investigate the process of engagement in treatment, understand the nuances of family treatment, and to uncover positive outcomes associated with family …


Materials For Incorporating I/O Into An Introductory Psychology Course, Joseph A. Allen, Carrie Bulger, Chris Cunningham, Lisa Kath, Mike Horvath, Morrie Mullins, S. Tonidandel Jan 2013

Materials For Incorporating I/O Into An Introductory Psychology Course, Joseph A. Allen, Carrie Bulger, Chris Cunningham, Lisa Kath, Mike Horvath, Morrie Mullins, S. Tonidandel

Psychology Faculty Publications

The following materials were created by the Society for Industrial and Organizational Psychology (SIOP) in an effort to produce some “shovel-ready” modules for incorporating I-O Psychology topics directly into Introductory Psychology courses. Although interest in I-O psychology has grown among students, very few introductory psychology textbooks cover the topic. Therefore, we have designed modules that correspond directly with the topics typically discussed in introductory psychology courses (e.g. Biopsychology in the workplace, Memory and Job Performance, etc.) that can be “cut-and-pasted” into already prepared lectures.


The Signal Provision Of Emotion: Using Emotions To Enhance Reliability Via Sensemaking, Joseph A. Allen, Cliff Scott, Sarah Tracy, John Crowe Jan 2013

The Signal Provision Of Emotion: Using Emotions To Enhance Reliability Via Sensemaking, Joseph A. Allen, Cliff Scott, Sarah Tracy, John Crowe

Psychology Faculty Publications

High reliability organization (HRO) theory suggests that early detection of and swift responses to potentially hazardous and situation changing events in organizational environments is central to the sustainability of reliable operations. Limited research on HRO’s (e.g. military groups and firefighters) considers how normative demands on feeling and emotion help to explain why some events are recognized and responded to while others not. In this article, we propose a model of enactment of anomalous events (i.e., situation changing events) that considers the manner in which emotions are regulated in high reliability contexts and how this influences the extent to which early …


Training For Decision Making In Complex Environments: Instructional Methods And Individual Differences, Jessica Ray Jan 2013

Training For Decision Making In Complex Environments: Instructional Methods And Individual Differences, Jessica Ray

Electronic Theses and Dissertations

Increased technology reliance along with today’s global fast paced society has produced increasingly complex, dynamic operating environments in disciplines as diverse as the military, healthcare, and transportation. These complex human machine systems often place additional cognitive and metacognitive demands on the operator. Thus, there is a crucial need to develop training tools for all levels of operators in these dynamic systems. The current study was designed to empirically test the effects of four training methods on performance and mental model accuracy in a microworld simulation game. It was hypothesized that process-focused guidance targeting metacognitive level processes as well as combined …


Bisexuality And Identity Formation, Jessica Fuoss Jan 2013

Bisexuality And Identity Formation, Jessica Fuoss

Electronic Theses and Dissertations

This study explores the identity development and psychological adjustment of bisexual individuals (n = 138) as compared to homosexual (n = 45) and heterosexual participants (n = 558). Undergraduate students recruited from psychology classes at a large metropolitan university in Florida (67% female, 65% Caucasian) took an online survey for course extra credit. Bisexual and homosexual participants scored higher in identity exploration than the heterosexual participants. Bisexual participants scored significantly higher in psychological symptom severity than heterosexual participants. The three groups were not significantly different in identity commitment nor in identity distress. Female bisexual participants scored more similar to the …


An Event-Related Potential Investigation Of Error Monitoring In Adults With A History Of Psychosis, Chi Chan Jan 2013

An Event-Related Potential Investigation Of Error Monitoring In Adults With A History Of Psychosis, Chi Chan

Electronic Theses and Dissertations

Metacognition, which involves monitoring and controlling of one’s thoughts and actions, is essential for guiding behavior and organization of information. Deficits in self-monitoring have been suggested to lead to psychosis and poor functional outcome. Abnormalities in eventrelated potentials originating from the anterior cingulate cortex (ACC), a brain region associated with error detection, have been consistently reported in individuals with schizophrenia during error monitoring tasks. This study sought to examine whether these abnormalities are present in individuals with a history of psychosis across diagnostic categories and whether they are associated with subjective appraisal of self-performance and personality traits related to psychosis. …


Psychopathology And Functional Impairment In Adolescents With Social Anxiety Disorder, Franklin Mesa Jan 2013

Psychopathology And Functional Impairment In Adolescents With Social Anxiety Disorder, Franklin Mesa

Electronic Theses and Dissertations

Although social anxiety disorder is most often diagnosed during adolescence, few investigations have examined the clinical presentation of this disorder exclusively in adolescents. Prior studies have demonstrated that some clinical features of SAD in adolescents are unique relative to younger children with the condition. Furthermore, the extant literature on daily functional impairment in this population is limited. In this investigation, multiple areas of functioning were examined in adolescents with SAD (n = 16) and normal control adolescents (n = 14): specific social skills, subjective distress and physiological reactivity during one speech performance task and one social interaction task; alcohol use …


Strengths And Limitations Of Qualitative Approaches To Research In Occupational Health Psychology, Irvin Sam Schonfeld, Joseph J. Mazzola Jan 2013

Strengths And Limitations Of Qualitative Approaches To Research In Occupational Health Psychology, Irvin Sam Schonfeld, Joseph J. Mazzola

Publications and Research

Like all research methods, qualitative methods have strengths and limitations. This chapter describes seven strengths and five limitations. With an understanding of their strengths and limitations and how to minimize and/or balance them, occupational health psychology (OHP) researchers can benefit from qualitative methods. It is important to understand that qualitative findings do not establish generalizable cause-effect relations. However, qualitative methods can help an OHP researcher develop a theory of causality and derive hypotheses related to the theory and, thus, motivate quantitatively organized research designed to test the hypotheses. The challenge for the OHP researcher is to be mindful of what …


Unintentionally Unethical: How Uncivil Leaders Violate Norms And Hurt Group Performance, Christopher Coultas Jan 2013

Unintentionally Unethical: How Uncivil Leaders Violate Norms And Hurt Group Performance, Christopher Coultas

Electronic Theses and Dissertations

Incivility is a common form of low-grade aggression that lacks a clear intent to harm, that violates community norms and values for interpersonal conduct, and is often chronic in nature (Andersson & Pearson, 1999; Cortina, Magley, Williams, & Langhout, 2001). Because of its subtleties, it is difficult at times to detect and even more difficult to prevent. However, it is an essential phenomenon to research, due to its ubiquity and negative impact on worker outcomes such as job satisfaction and psychological health (Cortina et al., 2001). Incivility instigated by those in authority may be an even bigger problem, due to …


Gender-Related Values, Perceptions Of Discrimination, And Mentoring In Stem Graduate Training, Amy Roberson Hayes, Rebecca S. Bigler Jan 2013

Gender-Related Values, Perceptions Of Discrimination, And Mentoring In Stem Graduate Training, Amy Roberson Hayes, Rebecca S. Bigler

Psychology Faculty Publications and Presentations

Although girls and boys appear equally interested in most STEM fields during childhood and adolescence, men pursue academic research careers in most of these same fields at higher rates than women. We tested several prominent hypotheses concerning the causes of this differentiation. Specifically, 136 (59 women) doctoral students in the United States completed measures of their occupational values, views of the degree to which STEM careers afford their values, perceptions of gender discrimination in their department, mentor support, and satisfaction with their graduate training. Results indicated gender differences in students’ occupational values, ratings of career value affordances, and perceptions of …


Placental Corticotropin-Releasing Hormone Mediates The Association Between Prenatal Social Support And Postpartum Depression, Jennifer Hahn-Holbrook, Christine Dunkel Schetter, Chander Arora, Calvin J. Hobel Jan 2013

Placental Corticotropin-Releasing Hormone Mediates The Association Between Prenatal Social Support And Postpartum Depression, Jennifer Hahn-Holbrook, Christine Dunkel Schetter, Chander Arora, Calvin J. Hobel

Psychology Faculty Articles and Research

Three decades of research point to both biological and psychological risk factors for postpartum depression, but very little research integrates the two. This study bridged this gap by testing whether prenatal social support predicted depressive symptoms at 8 weeks postpartum in a multiethnic sample of 210 women and whether the stress hormone placental corticotropinreleasing hormone (pCRH), measured at 19, 29, and 37 weeks’ gestation, mediated this relationship. We found that prenatal family support predicted significantly fewer depressive symptoms postpartum and more gradual increases in pCRH from 29 to 37 weeks’ gestation. Furthermore, steeper increases in pCRH during this same period …


Relation Between Optimism And Lipids In Midlife, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky Jan 2013

Relation Between Optimism And Lipids In Midlife, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

This research examined optimism’s relationship with total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, and triglycerides. The hypothesis that optimism is associated with a healthier lipid profile was tested. Participants were 990 mostly white men and women from the Midlife in the United States study who were on average 55.1 years old. Optimism was assessed by self-report with the Life Orientation Test. A fasting blood sample was used to assess serum lipid levels. Linear and logistic regression models examined the cross-sectional association between optimism and lipids accounting for covariates such as demographic characteristics (e.g., education) and …


The Association Between Optimism And Serum Antioxidants In The Midlife In The United States Study, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky Jan 2013

The Association Between Optimism And Serum Antioxidants In The Midlife In The United States Study, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective Psychological and physical health are often conceptualized as the absence of disease, but less research addresses positive psychological and physical functioning. For example, optimism has been linked with reduced disease risk and biological dysfunction, but very little research has examined associations with markers of healthy biological functioning. Thus, we investigated the association between two indicators of positive health: optimism and serum antioxidants.

Methods The cross-sectional association between optimism and antioxidant concentrations was examined in 982 men and women from the Midlife in the United States study. Primary measures included self-reported optimism (assessed with the revised Life Orientation Test) and …

Faculty Publications - Doctor of Psychology (PsyD) Program

Abstract

Aims

Central nervous system (CNS) malignancies and/or their treatment in pediatric cancer survivors are known to be associated with deficits in neuropsychological functions. We report findings from a nation-wide study of childhood cancer survivors to investigate intelligence and attention/concentration from a multi-dimensional perspective in a diverse sample from this population.

Main methods

Four hundred forty-four pediatric cancer survivors between 6 and 17 years of age, who had suffered CNS involvement associated with their malignancy, were evaluated. All patients completed a measure of general intelligence. Attention was measured by a continuous performance test (CPT) and by parental report using a …


Gene X Environment Effects Of Serotonin Transporter, Dopamine Receptor D4, And Monoamine Oxidase A Genes With Contextual And Parenting Risk Factors On Symptoms Of Oppositional Defiant Disorder, Anxiety, And Depression In A Community Sample Of 4-Year-Old Children, John V.

Psychology: Faculty Publications and Other Works

Genetic factors can play a role in the multiple level of analyses approach to understanding the development of child psychology. The present study examined gene-environment correlations and Gene x Environment interactions for polymorphisms of three target genes, the serotonin transporter gene, the D4 dopamine reactor gene, and the monoamine oxidase A gene in relation to symptoms of anxiety, depression, and oppositional behavior. Saliva samples were collected from 175 non-Hispanic White, 4-year-old children. Psychosocial risk factors included socioeconomic status, life stress, caretaker depression, parental support, hostility, and scaffolding skills. In comparison with the short forms (s/s, s/l) of the serotonin transporter …


Examining The Direct And Interactive Effects Of Positive Coping On Depressive Symptomology In African American Women, Heather Andrea Eaddy Jan 2013

Examining The Direct And Interactive Effects Of Positive Coping On Depressive Symptomology In African American Women, Heather Andrea Eaddy

Theses and Dissertations

In the larger stress and coping literature, several studies have examined ethnic differences in stress experiences and coping behaviors (Plummer and Slane, 1996; Slavin et al., 1991; Brantley et al., 2002). However, these studies are often comparative in nature and fail to examine within group variation (Plummer & Slane, 1996; Slavin et al., 1991; Smith, 1985). Similarly, studies have also neglected to examine how African American women cope when confronted with certain stressors and the associated mental health outcomes. With this in mind, the goal of the current study is to close existing gaps by examining the relationship between routine …


Examining The Interaction Of Neonatal Alcohol And Hypoxia In Vitro, Megan L. Carter Jan 2013

Examining The Interaction Of Neonatal Alcohol And Hypoxia In Vitro, Megan L. Carter

Theses and Dissertations--Psychology

Exposure to ethanol (ETOH) during fetal development results in a range of cognitive/behavioral deficits. There are differences in sensitivity to the effects of ETOH that could be explained by other factors, such as hypoxia. Similar mechanisms of damage underlie both ETOH, more specifically ETOH withdrawal, and hypoxia. Based on this overlap, it was hypothesized that sub threshold levels of these insults may interact to produce increased damage in sensitive brain regions. This study used a rodent organotypic hippocampal slice culture model to investigate the interaction of hypoxia and ETOH withdrawal and to determine possible developmental differences in the sensitivity to …


Forgiving Warriors: Does Outgroup Threat Reduce Ingroup Aggression Among Males?, David Chester Jan 2013

Forgiving Warriors: Does Outgroup Threat Reduce Ingroup Aggression Among Males?, David Chester

Theses and Dissertations--Psychology

In order to defend against outgroups, males and females respond to outgroup threat with different strategies. Specifically, males have been shown to respond to outgroup threat with increased ingroup solidarity and cooperation which is likely reflective of their ancestral role as warriors. What remains unknown is whether this cooperative warrior mindset among males not only increases ingroup prosociality, but also decreases ingroup aggression. Aggression against ingroup members under outgroup threat would likely disadvantage the ingroup by reducing the ingroup’s collective formidability. Further, prosocial motivations inhibit aggression. As such, I hypothesized that sex and outgroup threat would interact such that males, …


The Impact Of Religiosity Dimensions And Ethnic Identity On Well-Being In African American Women, Ebony S. Vinson Jan 2013

The Impact Of Religiosity Dimensions And Ethnic Identity On Well-Being In African American Women, Ebony S. Vinson

Theses and Dissertations--Psychology

Religiosity is considered to be an important component of the cultural orientation and worldview of African Americans. African American women, in particular, have been found to be unique in their level of religious devotion and activity compared to other demographic groups but there has been minimal research examining the positive effects of religiosity over time. The purpose of the current study was to investigate the role of religiosity dimensions and ethnic identity in predicting self-esteem, social support, healthy behaviors, and licit drug use in African American women over time. Results indicate that behavioral and cognitive components of religiosity predict different …


Bayesian Analysis Of Parental Drinking Motives And Children's Adjustment, Aaron A. Duke Jan 2013

Bayesian Analysis Of Parental Drinking Motives And Children's Adjustment, Aaron A. Duke

Theses and Dissertations--Psychology

Harm reduction strategies can mitigate against some of the deleterious effects of alcohol on families. These strategies are most feasible and cost-effective when they can be targeted at those who are most at risk. Previous studies examining the relation between parents’ alcohol use and their children’s psychological adjustment have failed to consider important contextual questions such as drinking motives. The current investigation set out to identify the extent to which parents’ drinking motives predict internalizing and externalizing psychopathology in their children. The investigation consisted of cross sectional analysis of parents’ drinking motives and their children’s adjustment using data from 154 …


Does Botox Buffer The Negative Effects Of Social Rejection?: A Test Of The Facial Feedback Hypothesis, Vicki Sharif Jan 2013

Does Botox Buffer The Negative Effects Of Social Rejection?: A Test Of The Facial Feedback Hypothesis, Vicki Sharif

Theses and Dissertations--Psychology

Can a common facial cosmetic procedure buffer against the negative impact of adverse social interactions? This pilot tested the hypothesis that an injection of botulinum toxin (Botox) to the corrugator supercilii muscles used in anger, compared to a placebo injection to the same location, will reduce the impact of social rejection on mood, self-esteem, control, meaningful existence, and aggression. Freezing facial musculature was hypothesized to alter the first physical signal of negative emotional reactions, thereby reducing the impact of social rejection on distress and aggression. This was the first study using Botox to examine the effects of reduced facial feedback …


Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul Jan 2013

Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul

Theses and Dissertations--Psychology

Borderline Personality Disorder (BPD) is a disabling condition characterized by chronic emotion dysregulation and behavioral impulsivity. Prospective studies that test proposed mechanisms of within-person change in BPD hold the key to improving symptom predictability and control in this disorder. A small body of evidence suggests that fluctuations in estradiol such as those occurring naturally at ovulation during the monthly female reproductive cycle may increase symptoms in women with BPD (DeSoto et al., 2003). Furthermore, there is preliminary evidence that both self-esteem and feelings of social rejection are highest at ovulation, when estradiol peaks (Durante and Hill, 2009; Eisenlohr-Moul et al., …


Characterizing Consumption, Dependence, And The Role Of Glucocorticoids In An Animal Model Of Voluntary Ethanol Consumption, Lynda Sharrett-Field Jan 2013

Characterizing Consumption, Dependence, And The Role Of Glucocorticoids In An Animal Model Of Voluntary Ethanol Consumption, Lynda Sharrett-Field

Theses and Dissertations--Psychology

Alcohol abuse disorders (AUD) represent a serious worldwide health problem with far reaching social, financial, and interpersonal implications. One of the most devastating facets of these disorders is the propensity to relapse following periods of abstinence. Ethanol withdrawal (EWD) is believed to promote relapse by increasing anxiety and craving, and may contribute to the development of cognitive decline associated with long-term dependence. Clinical data suggest that stress also plays a main role in both the development of AUD as well as relapse to drinking. As a physiological stressor, EtOH elevates levels of stress hormones (cortisol in humans, corticosterone (CORT) in …


The Whole Picture: Body Posture Recognition In Infancy, Alyson J. Hock Jan 2013

The Whole Picture: Body Posture Recognition In Infancy, Alyson J. Hock

Theses and Dissertations--Psychology

Holistic image processing is tied to expertise and is characteristic of face and body processing by adults. Infants process faces holistically, but it is unknown whether infants process body information holistically. In the present study, we examined whether infants discriminate changes in body posture holistically. Body posture is an important nonverbal cue that signals emotion, intention, and goals of others even from a distance. In the current study, infants were tested for discrimination between body postures that differ in limb orientations in three conditions: in the context of the whole body, with just the limbs that change orientation, or with …
