Electroencephalographic Asymmetry, Emotion Regulation, And Their Relationships With Depression Risk, Aliza Jacob

Dissertations, Theses, and Capstone Projects

Background: Research investigating patterns of electroencephalographic (EEG) brain asymmetry aids our understanding of neural systems involved in the processing of emotion, motivation, and psychopathology. Withdrawal-motivated negative emotions characteristic of depression are associated with relative right prefrontal cortex (PFC) activity, whereas approach- motivated positive emotions are associated with relative left PFC activity. Styles of emotion regulation (ER), or modulation of the intensity and duration of emotional responses, are also associated with presence (e.g., suppression, or maladaptive ER) versus absence (e.g., cognitive reappraisal, or adaptive ER) of depression vulnerability. Most PFC asymmetry studies of emotion, depression, and/or ER rely upon EEG recorded …

Clinical Characteristics And Neuroanatomical Predictors Of Acute Antidepressant Outcome For Patients With Comorbid Depression And Mild Cognitive Impairment, Jeffrey N. Motter

Dissertations, Theses, and Capstone Projects

Background: Older adults presenting with both a depressive disorder (DEP) and cognitive impairment (CI) represent a unique, understudied population. The classification of cognitive impairment severity continues to be debated though it has recently been subtyped into late (LMCI) versus early (EMCI) stages. Previous studies have found associations between treatment outcome and both cortical thickness and white matter hyperintensities (WMH), though report inconsistent directionality and affected regions. In this study, we examined baseline clinical characteristics and neuroanatomical features as prognostic indicators for older adults with comorbid DEP and CI participating in an open antidepressant trial. EMCI is hypothesized to have greater …

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 …

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …

Impact Of Religiosity And Level Of Acculturation On Cultural Alignment: An Exploration Of Terror Management Mechanisms Among Muslim American Women, Farah T. Goheer

ABSTRACT

Impact of Religiosity and Level of Acculturation on Cultural Alignment: An Exploration of Terror Management Mechanisms among Muslim American Women

by

Farah Taha Goheer, M.A.

Advisor: Joel Sneed, Ph.D.

Background: Terror management theory (TMT) is based upon the notion that human beings require ongoing psychological protection from the unyielding, existential threat of death. A large body of evidence has shown that human beings manage death-related terror by aligning with and endorsing the dominant views of their cultural worldviews. Notably, as immigrants experience a new culture, worldviews become rearticulated to incorporate elements of host and heritage cultures. However, it is …

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 …

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 …

Mindfulness In Medicine: Modified Mindfulness-Based Stress Reduction (Mbsr) Program Among Future Doctors, Virtue Sankoh

Dissertations, Theses, and Capstone Projects

Medical trainees are at particular risk for stress-related illness, including mental health problems such as suicidal ideation, substance abuse, and mood disorders. A vast literature on mindfulness-based stress reduction (MBSR), consisting of mindfulness education and structured meditative practices, has consistently demonstrated that MBSR and related mindfulness-based interventions improve mental and physical health, as well as one’s overall sense of well-being. Moreover, theorists and researchers have begun to suggest further that mindfulness plays a particular role in social cognition, or social-emotional learning. Medical schools have long been interested in ways to improve the “soft skills” related to interpersonal connectedness that are …
