A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

Family Fragments: Pressure And Proximity In First-Episode Psychosis, Cassandra B. Seltman

Dissertations, Theses, and Capstone Projects

This study explores the value of assuming a position that decenters the identified patient in families with a member with schizophrenia. Instead, a systemic view of the family is taken, as subject to pressures from without and within, and utilizing observable processes for the management and discharge of tension. It attempts the difficult balance of thinking dynamically without sacrificing scientific rigor, considering the social without discounting the biological, and exploring the functionality of the family without collapsing into blame, reductive cause-and-effect thinking, and the search to prioritize one true origin.

When treating family members as discrete units around an identified …

The Role Of The Infralimbic-Basal Forebrain Pathway In Fear Extinction, Carolina Maria Fernandes Henriques

Dissertations, Theses, and Capstone Projects

The medial prefrontal cortex (mPFC) is a key region for emotion regulation, and its failure to regulate extinction of aversive memories is associated with Post Traumatic Stress Disorder. Study of how the Infralimbic cortex (IL), a subregion of the mPFC, directly communicates with the Basolateral Amygdala (IL-BLA), has thus far failed to uncover the circuit mechanisms that lead to mPFC-mediated amygdala suppression of firing and diminished fear responses during extinction retrieval. One problem of this model is that it doesn’t incorporate indirect IL communication with the BLA. A key region to help understand how IL modulates extinction is the basal …

Demarcating Psychopathologies: Nosology, Validity, And The Taxonomic Problem In Psychiatric Medicine, Julia Zentz Kolak

Dissertations, Theses, and Capstone Projects

In this dissertation, I argue that the discussion surrounding the role of values in the conceptualization of mental disorders is reproduced in critical debates surrounding the issue of reliability and validity in a psychiatric nosology. In so doing, I oppose the conventional separation of the demarcation problem and the crisis of validity in psychiatric classification, arguing instead that they are inextricably linked. After drawing out the intersection between these literatures in the conceptual history of the DSM and its much-maligned transition to an etiologically neutral taxonomy of mental disorders, I consider Carl Hempel’s proposed conciliation between descriptive and theoretical systematization …

Effects Of Chronic Stress On Safety Processing And Physiology In The Medial Prefrontal-Amygdala-Basal Forebrain Circuit, Itamar S. Grunfeld

Dissertations, Theses, and Capstone Projects

Chronic stress increases generalization of fear to non-threatening cues, a key symptom in numerous psychiatric mood disorders. However, the mechanisms through which stress impacts safety learning remain poorly understood. To probe the relationship between stress and safety learning, this dissertation employed multiple behaviors, in conjunction with in-vivo multisite physiology during explicit safety and fear discrimination learning. In Chapter 1, I outline the role of chronic stress in driving neurological adaptations that result in generalized fear and highlight how this occurs because of impaired safety cue encoding. In Chapter 2, I show that chronic stress in the form of social defeat …

Reducing Fear Overgeneralization With Safety Learning: Attention Bias As A Moderator, Boyang Fan

Dissertations, Theses, and Capstone Projects

Anxiety disorders are the most prevalent mental health condition and affect one out of nine individuals around the world. Fear generalization is a neurocognitive mechanism thought to maintain and exacerbate anxiety, and thus is an important target of therapeutic interventions. Yet, intervention research and practice place relatively little emphasis on its importance. Given that a significant proportion of individuals do not respond to extant treatments of anxiety disorders, a strengthened focus on fear generalization may inform the development and personalization of new treatment approaches. Recent notions have linked fear generalization to failures in distinguishing between signals that predict the occurrence …

Informed Consent: Foundations And Applications, Joanna Smolenski

Dissertations, Theses, and Capstone Projects

Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case …

Training And Individual Predictors Of Attitudes Toward Serious Mental Illness Amongst Clinical Psychology Doctoral Students, Lauren K. O'Connor

Dissertations, Theses, and Capstone Projects

Clinical psychologists are grossly underrepresented in treatment provision for individuals with serious mental illness (SMI; Roe, Yanos, Lysaker, 2006). Systemic (e.g., emergence of managed care) and training-based (e.g., limitations to SMI specific training) factors contribute to the establishment of this underrepresentation, while mental health stigma amongst psychologists may play a role in perpetuating it. Many individual and experiential factors have been found to impact clinicians’ attitudes toward those with SMI (Henderson et al., 2014; Schulzes, 2007). Though many of these factors are present and relevant from the beginning of one’s career and may involve elements related to training, little research …

Food Restriction And Body Image Distortion In Pregnant Mothers: Outcomes For Exposed Children, Kathryn M. Dana

Dissertations, Theses, and Capstone Projects

Background: Developmental trajectories in the growing child do not originate at birth. Rather, critical periods may exist in pregnancy, during which the determinants of malnutrition are especially vulnerable to the effects of stress and other complications. Prenatal malnutrition has been consistently associated with negative consequences for the growth, development, and overall physical and mental health of affected offspring in both human and animal models. While most available literature on human prenatal malnutrition comes from famine research, there is some evidence that restrictive eating disorders in pregnant women may be associated with similar outcomes.

Hypotheses: We hypothesize that prenatal exposure to …

Overcoming Challenges In The Assessment And Treatment Of Problem Behavior In Adults With Autism, Julia A. Iannaccone

Dissertations, Theses, and Capstone Projects

Problematic behaviors, such as self-injurious behavior or aggression, demonstrated by adults with autism spectrum disorder (ASD), create many significant life complications, some life-threatening. Applied Behavior Analysis (ABA) is established as an evidence-based approach to treat problem behavior for children with ASD and shows promise as an effective treatment for adults, yet little research has been conducted within the adult population. Assessment and treatment of problem behavior with adults is often challenging due to funding limitations, increased severity and complexity of problem behavior, and underqualified staff. The purpose of the present study was to overcome these challenges by (1) identifying a …

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 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 …

Diagnosing The Will To Suffer: Lovesickness In The Medical And Literary Traditions, Jane Shmidt

Dissertations, Theses, and Capstone Projects

Throughout Western medical history, unconsummated, unreturned, or otherwise failed love was believed to generate a disorder of the mind and body that manifested in physiological and psychological symptoms. This study traces the medical and literary history of lovesickness from antiquity through the 19^th century, emphasizing significant moments in the development of the medical discourse on love. The project is part of the recent academic focus on the intersection between the humanities and the medical sciences, and it situates literary texts in concurrent medical and philosophical debates on afflictions of the psyche. By contextualizing the fictional works within the scientific …

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 …

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 …

A Conceptualization Of The Body In Psychodynamic And Body-Based Psychotherapies: Areas Of Overlap And Possibilities For Integration, Aleksandra Rayska

Dissertations, Theses, and Capstone Projects

The distinction between verbal and nonverbal psychotherapies is clearly visible in theory and clinical practice. Moreover, this duality of approaches promotes a split between the body and the mind, defining them as separate from each other. This dissertation helps bridge the divide between the literature in body-based therapies and verbally-based psychotherapy by (i) exploring the conceptual frame used to understand the body in psychodynamic therapy (ii) identifying the areas of overlap between psychodynamic theory and theories that underlie body-based psychotherapies, and (iii) proposing ways in which psychodynamic and body-based theories can inform one another. A clinical case was used to …

Object Relations In Children's Projective Testing: Applying The Mutuality Of Autonomy Scale To The Thematic Apperception Test, Lily A. Thom

Dissertations, Theses, and Capstone Projects

Psychodynamic assessment of object relations on projective tests has consistently been shown to contribute to a better understanding of children’s psychological functioning and to guide therapeutic interventions (Tuber, 1992). This research examines the enhanced utility of applying a psychodynamically-derived scale of children’s object relations to a commonly used projective assessment tool, the Thematic Apperception Test (TAT) (Morgan & Murray, 1935; Murray, 1943). The current study investigates the adaptation and application of the Mutuality of Autonomy Scale (MOA) (Urist, 1977; Urist & Shill, 1982), commonly used as a Rorschach Inkblot Method object relations scale, to examine verbal narratives on the TAT. …

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …
