Fnirs Measures Of Prefrontal Cortex Lateralization During Stuttered And Fluency-Enhanced Speech In Adults Who Stutter, Danra M. Kazenski

Graduate College Dissertations and Theses

The present study compared lateralization of cortical activation patterns in the prefrontal cortex (PFC) of adults who stutter (AWS) and typical speakers (TS) as measured with functional near infrared spectroscopy (fNIRS) in habitual and fluency-enhanced speaking conditions.

Participants were AWS (n = 11) and gender- and age-matched TS (n = 11) who completed speaking tasks in three condition blocks: (1) habitual speech using no speaking strategy (2) prolonged speech after receiving short-term training in fluency-shaping strategy-use (3) syllable-timed speech after being trained to speak in rhythm with a metronome at 92 beats per minute.

The three primary dependent variables were …

The Influence Of Prenatal Stress On Behaviors Associated With Schizophrenia And Autism Spectrum Disorder., Harold Bauerle

Graduate College Dissertations and Theses

Disorders such as schizophrenia (SCZ) and austism spectrum disorder (ASD) have long been associated with prenatal stress. In these three experiments, we attempted to correlate stress during gestation with behaviors considered to have good facial validity with SCZ and ASD in both juvenile and adult animals. To differentiate the effects of prenatal stress (PS) from the effects of early life stress due to a dam's behavior (MS), half of offspring animals were cross fostered to dams treated in the alternative condition as the offspring during pregnancy in experiments 2 and 3. In experiment 1, but not in 2 or 3, …

Distress Intolerance And Cannabis Use: An Initial Empirical Investigation, Julianna Brett Hogan

Graduate College Dissertations and Theses

Within the United States (U.S.), one-third of those who use cannabis (the most commonly used illicit drug in the U.S.), exhibit cannabis use problems significant enough to warrant a diagnosis of cannabis use disorder (CUD; Compton, Grant, Colliver, Glantz, & Stinson, 2004). Data suggests that quitting cannabis is highly difficult (Copersino et al., 2006), yet, there is little empirical knowledge about the nature of factors that relate to quit processes (e.g., self-efficacy). One potentially promising variable of relevance to CUD is distress intolerance (Leyro, Zvolensky, & Bernstein, 2010). Distress intolerance is referred to as (a) the perceived capacity to withstand …

Discrepant Attentional Biases Toward Sexual Stimuli, Martin Seehuus

Graduate College Dissertations and Theses

There are at least two types of response to stimuli: an automatic response that happens before conscious thought (a Type 1 response) and a deliberative, intentional response (a Type 2 response). These responses are related to behavior associated with the affective loading of the stimulus presented. Prior research has shown, for example, that a Type 1 tendency to spend more time looking at fear-provoking stimuli is associated with higher levels of general anxiety, while a Type 2 tendency to spend more time looking away from happy faces is associated with higher levels of depressive symptoms. Some stimuli categories elicit mixed …

Moderating Effects Of Coping On Associations Between Stress Reactivity And Internalizing And Externalizing Problems, Amy Aliza Paysnick

Graduate College Dissertations and Theses

The present study was motivated by a need to employ multilevel studies to better understand why the experience of stressful life events is predictive of increased rates of psychopathology. Specifically, this study aimed to test the moderating role of coping on associations between stress reactivity (autonomic arousal) and broad-spectrum internalizing and externalizing problems in a normative sample. Participants were 140 adolescents and emerging adults (ages 14-30 years; 60% female) who completed questionnaires on coping, stressful life events, personality, and behavioral/emotional problems. Skin conductance and heart rate data were also measured while participants completed two laboratory stress tasks: a public speaking …

Barriers To Recovery For Bangor's Buprenorphine Patients, John R. Mclaren, Erin Keller

Family Medicine Clerkship Student Projects

There are several buprenorphine providers at EMMc's Center for Family Medicine serving the greater Bangor, ME region - an area of substantial opiate use. Among the patient population of outpatient buprenorphine users, both locally and nationally, there are high rates of relapse (~32%). In order to decrease relapse rates, it's first imperative to conduct a baseline review of the current buprenorphine population to identify specific types of patients who are at higher risk of relapse. By understanding the barriers to recovery, the office hopes to apply an intervention to the current program, targeting this local demographic more effectively.

Conversational Topic Moderates Visual Attention To Faces In Autism Spectrum Disorder, Ashley Rae Brien

Graduate College Dissertations and Theses

Autism Spectrum Disorder (ASD) is often accompanied by atypical visual attention to faces. Previous studies have identified some predictors of atypical visual attention in ASD but very few have explored the role of conversational context. In this study, the fixation patterns of 19 typically developing (TD) children and 18 children with ASD were assessed during a SKYPED conversation where participants were asked to converse about mundane vs. emotion-laden topics. We hypothesized that 1) children with ASD would visually attend less to the eye region and more to the mouth region of the face compared to TD children and that 2) …

Susceptibility To Peer Influence For Engagement In Relational Aggression And Prosocial Behavior: The Roles Of Popular Peers, Stress Physiology, And Gender, Nicole Lin Lafko

Graduate College Dissertations and Theses

The overall goal of the current study was to determine if perceptions of popular peers' relationally aggressive (PPSRA) and prosocial behaviors (PPSP) were related to engagement in these behaviors in a sample of emerging adults. This study also investigated if these associations were moderated by sympathetic nervous system (SNS) and parasympathetic nervous system (PNS) reactivity to peer stress and gender. Although a significant amount of research suggests that aggressive behaviors can be socialized by peers (e.g., Molano, Jones, Brown, & Aber, 2013), there is a dearth of work that has examined relational forms of aggression that tend to be more …

Understanding Everyday Decisions: An Examination Of Biases In Decision-Making, Educational Attainment, And Use Of Tobacco And Nicotine Delivery Products Among Women Of Reproductive Age, Laura L. Chivers

Graduate College Dissertations and Theses

The aim of this study was to examine associations between biases in decision-making (delay discounting [DD], opportunity cost neglect [OCN], status quo bias [SQB]), educational attainment, and use of cigarettes and other tobacco and nicotine delivery products among women of reproductive age. Women of reproductive age are of special interest because of the additional risks that cigarette smoking or use of these other products represents should they become pregnant. Data were collected anonymously online in survey format using Amazon Mechanical Turk [AMT]. Participants were 800 women of reproductive age (24-44 years) from across the US. Half (n = 400) were …

Glycogen Synthase Kinase-3Β: An Investigation Of The Novel Serine 389 Phosphorylation Site, Brendan Deegan Hare

Graduate College Dissertations and Theses

Stress associated psychiatric disorders such as depression, anxiety, and post-traumatic stress disorder affect a large proportion of the population. Reductions in the complexity of neuronal morphology and reduced neurogenesis are commonly observed outcomes following stress exposure in rodent models and may represent a mechanism for the reduced brain volume in stress sensitive regions such as the hippocampus observed in individuals diagnosed with stress associated disorders. Multiple lines of evidence suggest that glycogen synthase kinase (GSK)-B may play a role in the neurodegenerative phenotype observed following stress exposure. GSK3B is atypical in that it is inhibited by phosphorylation. This inhibitory phosphorylation …

Factors In The Regulation Of Cycles Of Binge Eating Behavior, Andrew Knapp

Graduate College Dissertations and Theses

The reasons why people may periodically resort to binge eating behavior have long been a focus of study, and the reasons are elusive and varied. For people troubled by poor sleep and living with chronic stress, binge eating may be an attempt by the brain's glucose-depleted executive processing center to both regulate (i.e., increase) glucose levels and induce restorative sleep. Recovery resulting from restorative sleep may lead to a reduction in perceived stress, improved mood, and increased willpower, reducing the likelihood of another binge episode in close temporal proximity to the sleep-induced recovery. A repetitive cycle may ensue when stress …

The Impact Of Engagement With Community Supported Agriculture On Human Attitude Towards The Sustainable Food Movement, Ariana Margarita Cano

Graduate College Dissertations and Theses

With a total of 164 community supported agriculture programs (CSA), Vermont is leading the "locavore" movement in the United States, ranked number one in the country with the most CSAs and Food Hubs per capita. ("Locavore Index," 2013)

CSAs have a large positive impact on reducing carbon emissions, advancing local economic growth, and promoting healthy lifestyles of consumers. The purpose of this study is to explore the overall experience of individuals in comparison to their current social norm, individual attitudes, identity, and intentions of change, and understand any change overtime in their individual attitude and behavior.

Attitude change was measured …

Intuitions Or Informational Assumptions? An Investigation Of The Psychological Factors Behind Moral Judgments, Nolan Rampy

Graduate College Dissertations and Theses

There is an ongoing debate among psychologists regarding the psychological factors underlying moral judgments. Rationalists argue that informational assumptions (i.e. ideological beliefs about how the world works) play a causal role in shaping moral judgments whereas intuitionists argue that informational assumptions are post hoc justifications for judgments made automatically by innate intuitions. In order to compare these two perspectives, the author conducted two studies in which informational assumptions related to ingroups and outgroups varied across conditions. In Study 1, political conservatives and liberals completed the moral relevance questionnaire while imagining they were in the US, Iran, or no specific country. …

Wanting It Told: Narrative Desire In Cather And Faulkner, Monroe Street

Graduate College Dissertations and Theses

This thesis explores the role played by narrative desire within two modernist experimentations with novel form: Willa Cather's 1918 novel My Antonia and William Faulkner's Absalom, Absalom! (1936). In it, I argue that Cather and Faulkner utilize framing narratives in order to present the main plot of each novel as a product of multiple narrators' desire for a story to emerge. In My Antonia, it is the expressed wish of Jim Burden's nameless writer friend that compels him to finish writing his account of Antonia, which constitutes the main plot of the novel. Meanwhile, in Absalom, Absalom! it is …

A Randomized Pilot Trial: An Internet-Based Mind/Body Intervention To Mitigate Anxiety In Women Experiencing Infertility, Jessica Clifton

Graduate College Dissertations and Theses

Infertility is a frequently occurring chronic health condition, which often persists throughout the reproductive years. Heightened anxiety symptoms often are comorbid with infertility diagnoses. Women experiencing infertility, and particularly those with anxiety symptoms, characterize an emerging population that deserves special attention. However, women experiencing infertility have identified barriers to seeking psychotherapy (e.g., fears of being dismissed from fertility treatment and/or stigmatized). Consequently, women diagnosed with infertility need a psychotherapy that not only can reduce these symptoms, but can also be private and convenient. The current study translated an empirically tested in-person mind/body protocol into an internet-based intervention to suit the …
