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 …

Investigation Of The Relationship Between Mindfulness And Empathy In Pre-Nursing Students Exposed To A Four-Week Mindfulness Training, Debra L. Klich

Theses and Dissertations

Objective: To investigate the effects of a four-week mindfulness program on levels of mindfulness, empathy, and anxiety in a group of pre-nursing students.

Methods: This study utilized a multiple-baseline across subjects design. Results from nine study participants were examined.

Results: Data demonstrates that a detectable decrease in anxiety levels can result from participation in self-directed mindfulness program as short as four weeks. Results regarding mindfulness and empathy levels were less conclusive. A specific relationship between empathy and mindfulness cannot be determined from this study.

Conclusions: Because previous studies have demonstrated a persistence of skills, practice, and benefits acquired through mindfulness …

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 …

A Brief Rational Disputation Exercise Enhances Cardiovascular, Anxiety, And Affective Recovery Following Worry-Recall, Michelle Rosalie Di Paolo

Theses and Dissertations

Rational Emotive Behavior Therapy (REBT) (Ellis, 1958), educates a client on the relationship between one’s irrational beliefs (IBs) and the dysfunctional emotional/behavioral consequences of maintaining those beliefs such as symptoms of anxiety, depression, and sleep dysfunction (Ellis, Gordan, Neenan, & Palmer, 1997), symptoms also commonly correlated with high trait perseverative cognition (PC; Verkuil, Brosschot, de Beurs, & Thayer, 2009). In addition to symptoms of anxiety and depression, high levels of PC, a construct comprised of measures of trait worry and rumination, have been linked to acute cardiovascular (CV) health concerns that overtime when left unmitigated may lead to chronic conditions …
