Description
This project was generated out of a desire to understand and explore a novel twist on a well-traversed route to happiness. I set out looking for a new perspective on fulfillment and found sustainable, everyday joy through gratitude. In doing so, I created a space where a group of people could practice and share gratitude as a community. Gratitude is familiar to most as a feeling, but putting intention behind gratitude turns it into an action, and even a virtue. In fact, Roman philosopher Cicero says, "Gratitude is not only the greatest of virtues, but the parent of all others." I created a Facebook community called Marvel at The Ordinary (MATO) applying principles rooted in the Theory of Change to express this greatest virtue. I found both success and earnest support from others in this novel approach to current gratitude practices. Defined by Dr. Robert Emmons, an expert in the science of gratitude, practicing gratitude is a two-step process: "(1.) affirming goodness in one's life, and (2.) recognizing that the sources of this goodness lie at least partially outside of the self." There is substantial research touting the worth of gratitude journaling, in fact, few things have been more repeatedly and empirically vetted than the connection between gratitude and overall happiness and well-being. Yet there is one facet ubiquitously overlooked in current gratitude research: what happens when gratitude journaling is shared with others? With anecdotal evidence, short-form interview analysis, thematic analysis of journaling lexicon, and a case study on the growth and engagement of Marvel at The Ordinary as a social movement, there is reason to believe that a social media-based community centered around gratitude may support and even enhance the practice of gratitude, which is typically practiced in isolation. It was also found that communities of this sort are highly sought after, based on the engagement within and growth of the Facebook group from 50 to 600+ members in a period of 2 months. MATO set out with the aspirations of creating a community which encourages others to gratitude journal, raising awareness about gratitude journaling, and building a community which fosters empathy, optimism, and awareness in an everyday sense. In each of these goals, overwhelming success was found.

Description
Adults with autism spectrum disorder (ASD) face heightened risk of co-occurring psychiatric conditions, especially depression and anxiety disorders, which contribute to seven-fold higher suicide rates than the general population. Mindfulness-based stress reduction (MBSR) is an 8-week meditation intervention centered around training continuous redirection of attention toward present moment experience, and has been shown to improve mental health in autistic adults. However, the underlying therapeutic neural mechanisms and whether behavioral and brain changes are mindfulness-specific have yet to be elucidated. In this randomized clinical trial, I utilized functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to characterize fMRI functional activity (Study 1) and connectivity (Study 2) and EEG neurophysiological (Study 3) changes between MBSR and a social support/relaxation education (SE) active control group. Study 1 revealed an MBSR-specific increase in the midcingulate cortex fMRI blood oxygen level dependent signal which was associated with reduced depression. Study 2 identified nonspecific intervention improvements in depression, anxiety, and autistic, and MBSR-specific improvements in the mindfulness trait ‘nonjudgment toward experience’ and in the executive functioning domain of working memory. MBSR-specific decreases in insula-thalamus and frontal pole-posterior cingulate functional connectivity was associated with improvements in anxiety, mindfulness traits, and working memory abilities. Both MBSR and SE groups showed decreased amygdala-sensorimotor and frontal pole-insula connectivity which correlated with reduced depression. Study 3 consisted of an EEG spectral power analysis at high-frequency brainwaves associated with default mode network (DMN) activity. Results showed MBSR-specific and nonspecific decreases in beta- and gamma-band power, with effects being generally more robust in the MBSR group; additionally, MBSR-specific decreases in posterior gamma correlated with anxiolytic effects. Collectively, these studies suggest: 1) social support is sufficient for improvements in depression, anxiety, and autistic traits; 2) MBSR provides additional benefits related to mindfulness traits and working memory; and 3) distinct and shared neural mechanisms of mindfulness training in adults with ASD, implicating the salience and default mode networks and high-frequency neurophysiology. Findings bear relevance to the development of personalized medicine approaches for psychiatric co-morbidity in ASD, provide putative targets for neurostimulation research, and warrant replication and extension using advanced multimodal imaging approaches.

Description
Research on self-regulatory variables like mindfulness and effortful control proposes strong links with physical and mental health outcomes across the lifespan, from childhood and adolescence to adulthood and old age. One pathway by which self-regulation may confer health benefits is through individual differences in reports of and emotional responses to daily negative and positive events. Mindfulness is broadly defined as non-reactivity to inner experiences, while effortful control is broadly defined as attentional and behavioral regulation. Mindfulness and effortful control have both been conceptualized to exert their beneficial effects on development through their influence on exposure/engagement and emotional reactivity/responsiveness to both negative and positive events, yet few empirical studies have tested this claim using daily-diary designs, a research methodology that permits for examining this process. With a sample of community-dwelling adults (n=191), this thesis examined whether dispositional mindfulness (i.e., non-reactivity of inner experience) and effortful control (i.e., attention and behavioral regulation) modulate reports of and affective reactivity/responsiveness to daily negative and positive events across 30 days. Results showed that mindfulness and effortful control were each associated with reduced exposure to daily stressors but not positive events. They also showed that mindfulness and effortful control, respectively, predicted smaller decreases in negative affect and smaller increases in positive affect on days that positive events occurred. Overall, these findings offer insight into how these self-regulatory factors operate in the context of middle-aged adults’ everyday life.
