The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria

Dissertations, Theses, and Capstone Projects

Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …

Antecedents Of Borderline Personality Disorder And Antisocial Personality Disorder: An Examination Of Gene X Environment Interactions, Amy L. Medina

Dissertations, Theses, and Capstone Projects

Current thinking suggests that genotypes associated with impulse-control disorders and negative emotionality, such as monoamine oxidase-a (MAOA), interact with negative early environmental factors like childhood maltreatment and develop into the disorders know as Borderline Personality Disorder (BPD) and Antisocial Personality Disorder (ASPD). Using existing data from a prospective cohort design study of the consequences of child abuse and neglect, participants (N = 896 represent individuals with documented histories of child abuse and neglect and a matched comparison group that were followed up into adulthood and interviewed. A subsample of 631 participants gave permission for DNA extraction and analyses during …

Neurodevelopmental Mechanisms Of Adverse Trauma Outcomes In Emerging Adulthood, Olena Kleshchova

Dissertations, Theses, and Capstone Projects

Background: Exposure to traumatic stress and adversity during the formative years of development can have adverse effects on mental health, neuroendocrine stress system function, and the brain, that persist into adulthood. One candidate mechanism that might confer vulnerability to enduring adverse outcomes of early life trauma is disruption of normal brain maturation. As the brain matures, functional interactions among brain regions change until the functional brain architecture (i.e., the functional connectome) reaches a mature state in adulthood. Given that different neural circuits have distinct developmental trajectories and sensitive periods, traumatic stress at a given point in development might have …

Taking It To Heart: Trauma And Cardiovascular Risk In Court-Involved People Of Color, Tanya Erazo

Dissertations, Theses, and Capstone Projects

Research supports that racial disparities in health persist in the United States, with cardiovascular risk and cardiovascular disease remaining particularly high in low-income, communities of color (U.S. Department of Health and Human Services: Centers for Disease Control and Prevention, 2013; Winkleby, Jatulis, Frank, & Fortmann, 1992). Public health literature often focuses on sociodemographic variables when assessing for health disparities without considering trauma or forensic populations. This dissertation provides an overview of literature that examines cardiovascular disease and its relationship to trauma, particularly in low-income, communities of color, and forensic populations. Although the dissertation culminates in providing results for an investigation …

Attachment, Exploration, And Internalized Homonegativity, Gregory J. Gagnon

Dissertations, Theses, and Capstone Projects

Background: Internalized homonegativity (IH; a.k.a. internalized homophobia), has been implicated in health disparities between lesbian, gay, and bisexual persons (LGBs) and their heterosexual peers. Yet, little available research has explored factors that may increase or decrease IH.

Objective: This dissertation investigates relations between child and adult attachment and IH. It further examines the mediating and moderating roles of exploration and mentalization, respectively, in the attachment–IH relation.

Method: One hundred fifty cisgender LGB adults participated in two waves of an online survey. The first assessed recalled child–maternal and child–paternal attachment and current attachment to the romantic partner. The second, conducted two …

The Development Of Face Morphing Task To Assess Self Other Differentiation, Esen Karan

Dissertations, Theses, and Capstone Projects

Self-Other Differentiation (SOD) refers to a developmental process of acquiring a consolidated, integrated, and individuated sense of self. SOD develops at a) perceptual (e.g., facial perception) and b) representational (e.g., traits, mental states, and beliefs) levels. Impairments in representational SOD (R-SOD) are associated with many forms of psychopathology, particularly borderline personality disorder (BPD) and narcissistic personality disorder (NPD). Few studies to date have examined the perceptual aspects of SOD (P-SOD), which are hypothesized to develop from infancy onwards in tandem and in interaction with R-SOD. Given that the human face is one of the key characteristics that humans use to …

Does Ethnic Identity, In-Group Preference, And Acculturation Protect Latinas With A History Of Interpersonal Trauma From Developing Symptoms Of Ptsd?, Evelyn M. Ramirez

Dissertations, Theses, and Capstone Projects

Previous research suggests ethnic identity, a sense of belonging to a particular cultural group, may be protective against symptoms of post-traumatic stress disorder (PTSD). However, the role of ethnic identity, in-group preference (i.e., an individual’s preference for interactions with members of their own ethnic group) and acculturation (i.e., the level of comfort with the mainstream culture) have not been investigated as protective factors for Latinas with a history of interpersonal and sexual trauma. In this study, ethnic identity, in-group preference and acculturation were assessed via self-report on the Scale of Ethnic Experience in two samples of undergraduate Latina and non-Latina …

The Social Cost Of Pain: Rejection Sensitivity, Social Rejection, And Cannabis Use In Young Adults, Naomi Dambreville

Dissertations, Theses, and Capstone Projects

Cannabis has been implicated in relieving distress and social pain, an important area of research in young adult samples, given the saliency of peer and social networks to addiction. Cannabis, via opioid pathways, has been shown to reduce, or potentially buffer, the effects of social pain and rejection. Thus, cannabis may be protective against the painful feelings of social stress, particularly for heavier or more frequent users. However, findings are not wholly positive, as other research indicates cannabis may blunt affective responses and impair social processing. The effects of cannabis use in young adults are understudied, as well as its …

Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia

Dissertations, Theses, and Capstone Projects

Current developmental models of gender identity and gender dysphoria (GD) lack sex-specific profiles of brain function that differentiate between typically-developing and cross-gender identified youth, as postulated by models like the unified theory of the origins of sex differences (Arnold, 2009) and the neurobiological theory of the origins of transsexuality (Swaab & Garcia-Falgueras, 2009). Previously, investigators have used brain imaging modalities such as Resting-State functional Magnetic Resonance Imaging (R-fMRI) to demonstrate differences in resting-state functional connectivity (RSFC) between typically-developing male and female youth, and between typically-developing and GID-diagnosed youth. In the present pilot study, I used R-fMRI to investigate differences in …

What’S Your Story? Assessing Childhood Maltreatment Using The Thematic Apperception Test In An Adult Inpatient Population., Thachell C. Tanis

Dissertations, Theses, and Capstone Projects

There is a robust evidence that childhood maltreatment contributes to the development of adult psychopathology (Brown & Anderson, 1991; Johnson, Cohen, Brown, Smailes, & Bernstein 1999; Johnson, Smailes, Cohen, Brown, & Bernstein, 2000; Ruggiero et al., 1999). However, the identification of childhood maltreatment remains a methodological problem that results in inconsistencies in the reported incidence and psychological sequelae of maltreatment. A primary method for identifying histories of childhood maltreatment among adults is retrospective self-report measures which are susceptible to multiple biases (Briere, 1992; Cicchetti & Rizley, 1981; Shaffer, Huston, & Egeland, 2008). This present study suggests that childhood maltreatment can …

Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones

Dissertations, Theses, and Capstone Projects

The study of how the brain acquires fearful memories has attracted considerable experimental attention, due in part to the promise of discovering novel therapeutic approaches for psychiatric disorders that are characterized by unusually strong and persistent traumatic memories. In recent years, extensive research has focused on studying the neural and molecular mechanisms by which fear memories are acquired, stored, and retrieved in the brain. Once acquired, fear memories may be attenuated using one of 2 procedures: 1) fear extinction, which involves repeated presentation of the fear-arousing stimulus in the absence of an aversive consequence, or 2) interference with the reconsolidation …

Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins

Dissertations, Theses, and Capstone Projects

This capstone project examines dance, as an intervention and mindfulness practice that assists with managing our emotions. There is a need for dance therapy in social institutions such as, healthcare facilities, schools, and community centers. Dance therapy has the potential to reduce negative emotions, create mindfulness, improve self-expression, and promote a healthy well-being. I am proposing that dance therapy is applied as a regular practice in social institutions to develop mindfulness and promote emotional stability.

In this study, I argue that dance therapy can contribute to our well-being long term. In addition to this written thesis, a visual component of …

Psychosocial Correlates Of Post-Traumatic Stress Disorder Symptoms And Well-Being Among Hispanic World Trade Center Rescue And Recovery Workers, Dianne Ciro

Dissertations, Theses, and Capstone Projects

Thousands of first responders are estimated to have endured extremely distressing experiences during their recovery efforts at the 9/11 World Trade Center (WTC) site. While the effects of 9/11 continue to be studied, few studies have examined how rescue and recovery workers have been coping since 9/11 and how their coping is associated with their psychological well-being. Moreover, we do not know how distinct coping patterns may be associated with post-traumatic growth, experiences of positive emotion, or quality of life among WTC responders.

This study compared coping differences among Hispanic, Non-Hispanic White, and Non-Hispanic Black first responders. In addition, it …

Women’S Sexual Fantasies In Context: The Emotional Content Of Sexual Fantasies, Psychological And Interpersonal Distress, And Satisfaction In Romantic Relationships, Sarah Constantine

Dissertations, Theses, and Capstone Projects

Background: Psychoanalytic thinkers propose that aspects of an individual’s sexual fantasies are related to her psychological and interpersonal functioning. The present study aims to elucidate the significance of sexual fantasies with respect to women’s emotional and interpersonal lives. The study evaluated a model, which hypothesized that internal representations of self and others (e.g. attachment security, maturity of object relations) along with psychological and interpersonal factors would predict both the emotional content (guilt, fear, affection) of written sexual fantasy narratives, and overall romantic satisfaction in heterosexual women. Methods: Five hundred and thirty four women completed self-report questionnaires online. Subsequently, the sexual …

Cortical Thickness Abnormalities Within The Salience And Reward Networks In Older Depressed Adults With Apathy, Monique A. Pimontel

Dissertations, Theses, and Capstone Projects

Background and Significance: Apathy is a common comorbidity in late-life depression. Among older depressed adults, apathy is associated with a number of adverse outcomes, including increased disability, comorbid illness, and mortality. The etiological substrates of apathy in late-life depression nonetheless remain poorly understood, and little is known about its optimal treatment. To this end, the aim of the current study was to examine cortical abnormalities within the salience (SN) and reward networks (RN), two brain systems involved in the processing of incentive salience that may underlie the syndrome of apathy in older depressed adults.

Methods: We examined the association between …

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …

Medication Management In Pediatric Chronic Illness: Should Patient Anxiety Be Considered?, Claire J. Hoogendoorn

Dissertations, Theses, and Capstone Projects

Introduction: There is growing support that psychological symptoms can impact various aspects of disease, well-being, and medical treatment for those with a chronic illness like Crohn’s disease (CD). Yet, almost no studies have examined whether psychological symptoms can influence management or efficacy of patient medication regimens. The aims of this project were to examine whether anxiety predicted pediatric patients’ level of medication management, medication prescription changes, and corticosteroid prescription and duration.

Method: A total of 105 pediatric patients ages 8-18 (M=14.5, SD=2.3) completed a validated anxiety questionnaire during a GI office visit (baseline). Prescribed IBD …

Let Fall: Hysteria And The Psychoanalytic Act, Matthew W. Oyer

Dissertations, Theses, and Capstone Projects

This text proposes to examine the contemporary crisis of psychoanalysis by taking seriously feminist critiques of the theory’s phallocentrism, but arguing that the phallus cannot be metaphorically or metonymically replaced by any substitutive term, as most revisionist theories of psychoanalysis have sought to do. Castration is the central psychoanalytic concept, though the theory always seeks to cover it over. In order to develop a psychoanalysis that can confront this castration that is always repressed and yet, in its persistent return, continuously disrupts the continuity of psychoanalytic theory, a detour is proposed, returning to the origins of psychoanalysis and taking hysteria …

Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly

Dissertations, Theses, and Capstone Projects

A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant …

A Meta-Analysis Of The Prediction Of Violence Among Adults With Mental Disorders, Hing Po Lam

Dissertations, Theses, and Capstone Projects

The study of the risk for violence among persons with mental disorders has received substantial scientific attention over the past few decades; however, many uncertainties and controversies remain due to the wide disparities in the reported results. Using the state-of-the-art perspective of public health, a meta-analysis was conducted to clarify the ambiguities by synthesizing quantitative findings from 85 research reports (completed between January 1970 and May 2010) on violence risk assessment among mentally disordered adults. Results of this meta-analytic study revealed that the estimates of the prevalence of violence among the psychiatric population varied considerably from 1.1% to 78.4% with …
