Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward
Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward
Theses and Dissertations
The ability to effectively withhold an inappropriate response is a critical feature of cognitive control. Prior research indicates alterations in neural processes required for motor response inhibition in anxious individuals, including those with posttraumatic stress disorder (PTSD), and those who engage in regular cannabis use. However, thus far most research has examined how anxiety-related symptoms and cannabis use influence response inhibition in isolation of one another. The current study examined the interactions between anxious symptomology and recent cannabis use in a sample that recently experienced a traumatic event using functional magnetic resonance imaging (fMRI) during the completion of a Stop-Signal …
Moderating Effects Of Harm Avoidance On Resting-State Functional Connectivity Of The Anterior Insula, Ashley Ann Huggins
Moderating Effects Of Harm Avoidance On Resting-State Functional Connectivity Of The Anterior Insula, Ashley Ann Huggins
Theses and Dissertations
As an index of behavioral inhibition and an individual’s propensity to avoid, rather than seek, potentially dangerous situations, harm avoidance has been linked to internalizing psychopathology. Altered connectivity within intrinsic functional neural networks has been linked to internalizing psychopathology; however, less is known about the effects of harm avoidance on functional connectivity within and between these networks. Importantly, harm avoidance may be distinguishable from trait anxiety and have clinical relevance as a risk factor for psychopathology. To this end, the current study aimed to examine associations between harm avoidance and resting state functional connectivity. A sample of undergraduate students (n=92) …
Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout
Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout
Theses and Dissertations
Dispositional anxiety is an important risk factor for the development of anxiety and other psychological disorders. Symptoms commonly expressed by highly anxious individuals include intrusive memories, uncertainty, and worry — all occurring in the absence of immediate threat. This raises the possibility that anxious individuals have difficulty governing threat’s access to working memory, the mental workspace where goal-related information is actively retained for guiding on-going behavior. Using functional magnetic resonance imaging (fMRI) while 81 subjects completed a well-validated working memory task, I show that threat-related and neutral distracters unnecessarily gain access to working memory, as evidenced by increased neural activity …
Equity Of Social Support And Its Relationship With Depression, Anxiety, And Antiretroviral Medication Adherence Among Seroconcordant Dyads Of Hiv-Positive African Americans And Their Informal Supporters, Angela Roethel Wendorf
Equity Of Social Support And Its Relationship With Depression, Anxiety, And Antiretroviral Medication Adherence Among Seroconcordant Dyads Of Hiv-Positive African Americans And Their Informal Supporters, Angela Roethel Wendorf
Theses and Dissertations
Social support may be an important resource for those coping with stigmatized chronic illnesses, such as HIV/AIDS, as social support may buffer the deleterious impact of HIV-related distress (Derlega, Winstread, Oldfield, & Barbee, 2003; Stutterheim, Bos, Pryor, Brands, Liebregts, & Schaalma, 2011; Ueno & Adams, 2001). Yet little is known about characteristics of social support among HIV-positive patients in relationships with other HIV-positive individuals and whether there is an equivalent perception and provision of support between each patient in the relationship. To examine how equity of support within the dyad may contribute to nuances in social support, mental health outcomes, …
