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 …

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 …

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 …

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 …
