The Gut-Brain Axis: Investigating The Effects Of Diet, Physical Activity, And Prior Adversity On Anxiety Via Autonomic Nervous System, Jenna L. Pennella Jan 2025

The Gut-Brain Axis: Investigating The Effects Of Diet, Physical Activity, And Prior Adversity On Anxiety Via Autonomic Nervous System, Jenna L. Pennella

UNF Graduate Theses and Dissertations

Previous literature has highlighted a bidirectional relationship between the gut and brain called the gut-brain axis (de Punder & Pruimboom, 2015; Hill et al., 2008; Leistner & Menke, 2020). The current study aimed to investigate directional relations between different stressors (e.g. poor diet, vigorous activity, and prior adversity) and anxiety and how interactions with gut issues and autonomic dysfunction may impact these relationships. Based on previous literature, we examined (a) physical activity and diet as moderators of stress and anxiety as well as stress and GI symptoms, (b) GI symptoms as a mediator between various predictors (i.e., diet, stress, physical …

Self-organizing systems can shift between stability and flexibility in response to perturbation, a potential adaptive mechanism for understanding biopsychosocial resilience. Inverse Power-Law (IPL) structure, a frequency distribution that describes fractal patterns commonly produced by self-organization, produce measurements of stability and flexibility. This study applies these measures to emotional resilience at the start of the Covid-19 pandemic. Ratings of frequency over the past week (1-5 Likert scale) across 12 emotions (six positive and six negative) gathered in mid-April 2020 as part of a survey of adults’ (N = 4,094) pandemic experiences and health in the USA. The distributions of everyone’s emotion …


An Investigation Of The Physiological And Behavioral Correlates Of Mental Imagery, Matthew Daniel Carroll Jan 2025

An Investigation Of The Physiological And Behavioral Correlates Of Mental Imagery, Matthew Daniel Carroll

Graduate Theses/Dissertations

Many conventional theories hold mental imagery to be fundamental to self-regulation. Recently, a current of research into mental imagery has developed, with the terms anaurelia and aphantasia being coined for the inability to experience, respectively, auditory and visual thought content, yet little is known about the impact that such individual differences have on persons’ lives. The present experiment was performed in order to test the hypotheses that self-regulation and mental imagery positively correlate and that mental imagery mediates the correlation of resting heart-rate variability and self-regulation. Self-regulation was measured via a self-report questionnaire (the Short Self-Regulation Questionnaire), as was mental …
