The Relationship Between Cognitive Flexibility And Rumination: From Laboratory To Daily Life, Cassidy R. Girard

All NMU Master's Theses

Cognitive flexibility has been considered one of the risk factors for anxiety. People with high levels of anxiety tend to stick to more maladaptive strategies such as rumination. The interaction between cognitive flexibility and rumination may help explain the contribution of cognitive flexibility to the development of anxiety. This study investigated the relationship between cognitive flexibility and rumination. Each individual’s level of cognitive flexibility, anxiety, and rumination were measured through questionnaires and computer tasks. Daily changes in emotion and rumination were assessed using the experience sampling method. The results showed interesting relationship between rumination (both trait and momentary) and cognitive …

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell

All NMU Master's Theses

Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …

Evaluating Changes In Error-Monitoring Electrocortcial Responses As An Outcome Of Attention Bias Modification Training, Jeremy Andrzejewski

All NMU Master's Theses

Anxiety disorders are among one of the most debilitating and prevalent mental disorders. Maladaptive anxiety has been associated with enhanced attention bias to threat as well as heightened error-monitoring following an erroneous response. In an effort to reduce an anxious individual’s attention bias to threat, an attention training paradigm known as attention bias modification (ABM) was developed. While ABM training has demonstrated the ability to reduce attention bias and anxiety symptoms, there are inconsistencies in the magnitude of symptom reduction and there is a lack of neuroimaging support in regards to ABM outcome. Therefore, this study evaluated the outcome of …

Student Athletes' Perception Of Smartphone Use And Its Effects On Sleep Quality, Anxiety, And Depression, Alexis Schaefer

All NMU Master's Theses

ABSTRACT

STUDENT ATHLETES’ PERCEPTION OF SMARTPHONE USE AND ITS EFFECTS ON SLEEP QUALITY, ANXIETY, AND DEPRESSION

By

Alexis Schaefer

This study investigated the perception of smartphone use and its perceived effects on sleep quality, depression, and anxiety among NCAA collegiate student athletes (SA). One hundred and ninety one Northern Michigan University SA’s completed an online questionnaire consisting of original content and select components from the Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder Assessment (GAD-7), Patient Health Questionnaire (PHQ-9), and the Mobile Phone Problem Use Scale (MPPUS). Pearson product moment correlations examined relationships between demographic information and perception questions. Correlations …

Better Health Through Horticulture: Using Horticulture To Influence Behavior And Reduce Stress, Rachel Ochylski

All NMU Master's Theses

Horticultural intervention in the form of gardening workshops connect participants to nature while they nurture another living organism. Horticultural intervention provides opportunities to socialize and engage in a meaningful activity, which have been recognized as helpful in the treatment of common mental health difficulties such as depression and anxiety. There is a lack of experimental studies based on quantitative data that focus on the effects of horticulture on holistic human health. The author evaluated the effects of a horticultural intervention on two separate groups, older adults and college students. The behavioral effects of engaging in gardening activities were evaluated using …

Assessment Of Neurotensin Receptor Agonist Effects On Fear-Potentiated Startle, Mark Aaron Vanden Avond

All NMU Master's Theses

Systemic administration of the NTS₁ receptor agonist PD149163 has exhibited anxiolytic effects in male rats. The present study sought to further evaluate the potential anxiolytic effects of PD149163 by assessing this compound in both male and female C57BL/J6 mice using the fear-potentiated startle (FPS) paradigm. Startle chambers were equipped with a shock-grid floor, fluorescent light, and an acoustic startle speaker. Conditioning took place between the light and floor shock, and test sessions measured startle to a 90 dB noise burst while the light was on (FPS) or off. Startle magnitude did not differ between the male and female mice. …
