Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, Garima Singh
Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, Garima Singh
Psychology ETDs
Reinforcement learning (RL) enables agents to learn through interaction with their environment. This empowers individuals to optimize actions in complex and dynamic settings. The component of event related potential (ERP) termed as the Reward Positivity (RewP) evidently signifies a fundamental reward prediction error (RPE) associated with rewards. This characteristic implies that it represents a fundamental computational process in the assessment of RL. When a reward is particularly pleasurable or liked by an individual, it tends to elicit an amplified RewP signal, reflecting the heightened positive affect. RPE arises from disparities between anticipated and actual rewarding outcomes and is known to …
Predictors Of Recovery In Advocacy-Based Refugee Treatment Outcome: The Role Of Prior Traumatic Experiences And Current Chronic Stressors, Meredith A. Blackwell
Predictors Of Recovery In Advocacy-Based Refugee Treatment Outcome: The Role Of Prior Traumatic Experiences And Current Chronic Stressors, Meredith A. Blackwell
Psychology ETDs
Refugees are at an increased vulnerability to mental health disorders compared to citizens of wealthier nations. The present study looks at the symptom trajectories of 290 refugees in a psychosocial community-based participatory intervention. A three-level generalized linear mixed model examined the predictive impact of exposure to trauma and chronic stress at baseline on posttraumatic stress and mood symptoms over time. Results showed that only higher chronic stress at baseline was associated with a steeper decrease in both PTSD and mood scores, but these effects differed by nationality. However, with chronic stress entered as a time-varying covariate instead only African participants …

Essays On Emotional Well-Being, Health Insurance Disparities And Health Insurance Markets, Disha Shende
Economics ETDs
This dissertation has three research papers. First paper looks at the effect of social networks on emotional well-being of cancer patients by studying the response of social networks on their depression symptoms. Using the data from a primary survey conducted in Nepal, the study finds that social networks significantly reduce depression symptoms among cancer patients. The results strongly advocate for the importance of the social networks in improving their emotional well-being. Second paper examines the health coverage disparities among Hispanic and non-Hispanic young adults in five southwestern states of the United States. Using the pooled data from American Community Survey …
The Role Of Perceived Stress In The Relationship Between Purpose In Life And Mental Health., Anne Guzman
The Role Of Perceived Stress In The Relationship Between Purpose In Life And Mental Health., Anne Guzman
Psychology ETDs
Although purpose in life (PIL) has been consistently related to better mental health, there is little understanding of whether that may be explained by reducing appraisal of or reactivity to stress. The sample consisted of 546 undergraduate students who completed measures of PIL, perceived stress, and measures of both positive mental health (positive affect, life satisfaction) and negative mental health (negative affect, anxiety, depression). The hypotheses were that PIL would (1) be related to more positive and less negative mental health and (2) be related to less perceived stress, and (3) reduce the effects of perceived stress in increasing negative …
Evidence For Persistent Hypervigilance For Sexual Assault Survivors, Michãel Palmer
Evidence For Persistent Hypervigilance For Sexual Assault Survivors, Michãel Palmer
Psychology ETDs
Inhibition has been proposed as a cognitive mechanism that allows persons to screen out irrelevant information. This study investigated the effects of sexual assault on inhibition. Many sexual assault survivors experience intrusive memories of their assault that may be the result of deficient inhibitory processes. On the other hand, assault survivors often cope through avoidance which may strengthen inhibitory experience. Other hypotheses investigated the possibility that inhibitory strength changes across the healing process and that inhibition was related to trauma symptomatology. Forty-four survivors of sexual assault and seventy-nine non-assaulted controls were tested on two measures of inhibition: directed forgetting (a …
