Oral Contraception And Cognition, Kathleen Gerencer

Electronic Theses and Dissertations

Oral contraception is currently used by over 100 million women worldwide. Women utilize contraception not only to prevent pregnancy but also to manage a wide range of health concerns, such as acne and polycystic ovarian syndrome. Although this medication has granted women bodily autonomy, helped them attain higher levels of education, and helped them enter the workforce in greater numbers, little is known about the consequences outside of the intended contraceptive effects, specifically the cognitive and behavioral consequences. Moreover, because doctors can prescribe contraception after the first menstrual cycle and during puberty, it’s possible that this critical window of development …

Spontaneous Behavioral Coordination: The Impact Of Achieved And Desired Interpersonal Closeness On Synchrony And Mimicry, Morgan Stosic

Electronic Theses and Dissertations

The purpose of the present dissertation was to examine the impact of interpersonal closeness and the desire for interpersonal closeness on displays of behavioral synchrony and mimicry, simultaneously. Groups of two strangers (N = 182 participants, N = 91 dyads) were randomly assigned to complete a “closeness-inducing” task where partners took turns asking and answering intimate questions or a comparison “small-talk” task where partners asked and answered less-intimate questions. Additionally, dyads were randomly assigned to complete these tasks in real time over Zoom, or by reading and responding to the task’s questions over text. These tasks were intended to generate …

Do Good Things Come To Those Who Wait?: Investigating Temporal Discounting Rates Among Older Adults, Amy Halpin

Electronic Theses and Dissertations

Decision-making is widely viewed as a higher-order cognitive construct, drawing on fluid intelligence as well as intact functioning across a wide variety of cognitive domains including executive function, working memory, declarative memory, and attention. The conditions of the decision-making outcome (e.g., immediate or delayed), the framing of the outcome (e.g., loss vs. gain), and the type of outcome (e.g., money, food, social or health consequences), are consistently highlighted throughout the literature as being important influences on decision-making behavior. However, decision-making behavior among and within these contexts remains inconsistent and inconclusive in older adult populations. Considering that recent evidence suggests the …

Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan

Electronic Theses and Dissertations

Dementia is defined as gradual, progressive loss of cognitive functioning, greater than what is expected of normal aging, resulting in functional impairment. There are several types of dementia clinical syndromes that are accompanied by unique patterns of cognitive dysfunction and neuropathological changes. Alzheimer’s disease (AD) is the most common type of clinical dementia syndrome, accounting for approximately 60-70% of cases. Neuropathological mechanisms associated with AD include the disruption of the cholinergic system, accumulation of amyloid-beta plaques and hyperphosphorylated tau, as well as vascular pathology. Vascular pathology complicates the characterization of clinical and neuropathic changes in AD, as there becomes significant …

Exploring The Importance Of Values, Place, And Perceptions In Conservation Decision-Making In Maine: A Mixed Methods Approach, Alyssa R. Soucy

Electronic Theses and Dissertations

Conservation inherently involves intertwined ecological systems and human societies. In Maine, USA conservation decision-making brings together many viewpoints, values, motivations, and experiences to balance diverse goals. Socio-cultural, experiential, financial, and ecological factors can all influence an individual’s ability to make or support a decision. This dissertation aimed to broadly explore how people perceive their role in conservation decision-making in Maine. In doing so, we articulate a diverse set of perspectives, experiences, and values. We used a mixed methods approach which enabled an in-depth understanding of the complexity of conservation decision-making while providing the opportunity for different voices to be heard. …

Systemic Growth Factor Increases As A Result Of Exercise May Reduce Alzheimer's Disease Risk In Midlife Mice And Humans, Amanda Hewes

Electronic Theses and Dissertations

Alzheimer’s disease (AD) is a neurodegenerative disorder with insidious onset and slow progression. AD research has traditionally been based on neuronal and glial dysfunction due to hallmark beta-amyloid and tau pathologies. Although literature supports an association between AD and cardiovascular disease and/or cardiovascular risk factors, vascular dysfunction as an etiology of AD has been overlooked. Cardiovascular risk factors have been associated with both cardiovascular and cerebrovascular disease in midlife individuals, an age at which modifiable risk factor management may be the most beneficial. Up to half of AD cases worldwide and in the USA are attributable to modifiable risk factors. …

Uncertainty Monitoring In Category Learning And Transfer, Rose Deng

Electronic Theses and Dissertations

Uncertainty is commonly experienced by many people during learning and decision making. Given that many career paths require the ability to monitor uncertainty, it’s important to understand how metacognitive processes influence cognitive performance. In attempts to explore how uncertainty monitoring impacts learning, three experiments were conducted. The first and second experiment utilized a categorization task in which participants explicitly learned to categorize Chemistry concepts. The third experiment assessed the impact of uncertainty monitoring on implicit learning and utilized a different task to tap into the implicit learning system. The present dissertation is one of few to investigate the role of …

How Race, Gender, And Body Positioning Impact Perceptions And Interactions With Those In Power, Adele Weaver

Electronic Theses and Dissertations

How might the typical white perceiver behave while interviewing with a Black manager who puts her hands on her hips when she speaks? Would they act uncomfortable and anxious, leaning away from her? Would they engage with her and smile more? Lastly, would they react differently if the manager was a white man or a Black man? Even though it is known that Black people in expansive positions are perceived more negatively than white people in expansive positions, there has yet to be an observation of white people’s nonverbal behavior in interactions with Black and white individuals in different body …

Self-Regulation, Emotion Regulation, & Social Problem-Solving: Common & Distinct Pathways To Depression, Michelle L. Buffie

Electronic Theses and Dissertations

The present study examined the relationships among three psychological constructs: self-regulation (SR), emotion regulation (ER), and social problem-solving (SPS), and their connection to depressive symptomology. SR, ER, and SPS arose from independent, well-established literature bases and each has demonstrated links to psychopathology. The theories underlying these constructs, however, suggest overlap in their operationalization and measurement. Despite these concerns, no empirical investigations to date have examined the measurement and predictive validity of measures of SR, ER, and SPS in the context of one another. Undergraduate students aged 18-29 (N = 592) completed three self-report measures each of the constructs interest, …

Inhibitory Control And Mentalizing: Potential Contributing Factors To Maladaptive Interpersonal Behaviors Associated With Depressive Symptoms, Eliot Fearey

Electronic Theses and Dissertations

The current project considered the role of inhibitory control and mentalizing as vulnerability factors for engagement in excessive reassurance seeking, negative feedback seeking, and conversational self-focus among a sample of 222 older adolescents. It was hypothesized that lower levels of both inhibitory control and mentalizing would exacerbate the effect of elevated depressive symptoms on higher levels of the three interpersonal behaviors. Additional analyses further explored the role of self-reported gender identity. Models tested inhibitory control and mentalizing separately. In assessing inhibitory control, a self-report measure of impulsivity was used as a proxy for inhibitory control, and the Go/No-Go task was …

Social Capital, Indigenous Storytelling, And Fish Diversity: Learning Together Through Community-University Partnerships In Downeast Maine, Michelle De Leon

Electronic Theses and Dissertations

Not only can community-university partnerships be vehicles for mobilizing community resources and affecting change, they also have high potential to produce useful, nuanced research and enable renewed visions of trust. I explore partnerships rooted in trust in the context of a community-university partnership between the Passamaquoddy Tribe at Sipayik and the University of Maine and its work through the Passamaquoddy-led StoryMaps Team. To accomplish this, I take a transdisciplinary approach to incorporate diverse perspectives on understanding critical and ethical approaches to engagement with Indigenous communities. The central focus among all three chapters is the need for Indigenous communities and institutions …

An Experimental Investigation Into The Effects Of Trait And State Self-Criticism On The Benefits And Barriers To Non-Suicidal Self-Injury, Melissa Jankowski

Electronic Theses and Dissertations

Non-suicidal self-injury (NSSI; e.g., harming oneself without the intent to die) is a leading health concern, and research indicates rates of NSSI are increasing. Despite the clear negative implications of NSSI, mechanisms that reinforce the continual engagement in these behaviors remain unclear. The Benefits and Barriers Model (Hooley & Franklin, 2017) proposes there are barriers that prevent most individuals from engaging in these deleterious behaviors; however, once these barriers are eroded, one becomes more likely to engage in NSSI. One such barrier is a positive association with the self. Self-criticism is generally understood as a trait lowering desire to avoid …

The Role Of Confrontation Effectiveness For Women's Psychological Wellbeing After A Sexist Event, Shelby Helwig

Electronic Theses and Dissertations

This dissertation includes three experimental studies investigating how confronting sexism impacts college-aged women. In Studies 1 and 2, we investigated how confronting effectively versus ineffectively influenced women’s imagined (Study 1) and actual (Study 2) psychological wellbeing. In Study 3, we investigated how imagining the costs and benefits of confronting sexual harassment impacted women’s confrontational behavior and negative affect. All three studies supported the conclusion that an effective confrontation is a goal for most confronters (Study 3) and whether or not a confrontation is effective influences women’s imagined (Study 1) and actual (Study 2) psychological wellbeing. Beyond this, all three studies …

Co-Rumination, Romantic Relationships, And Depressive Symptom Development In Adolescence, Jessica L. Shankman

Electronic Theses and Dissertations

The present research aimed to better understand the associations among romantic involvement, co-rumination with friends, and depressive symptom development in a sample of 338 adolescents (ages 14-19 years). Using a multi-method, longitudinal study design, the present study examined whether co-rumination (self-reported and observed) mediated the relationship between romantic involvement and depressive symptoms over time. Next, analyses separately tested whether this process was further moderated by positive friendship quality, whether youth discuss romantic experiences during problem talk with friends, and/or gender. Analyses also tested whether romantic relationship quality among romantically involved youth influenced depressive symptoms over time via co-rumination.

Results supported …

I Am Kind, I Am Smart, I Am Important: The Effects Of Self- Affirmation On Women’S Confrontational Responses To Sexism, Kathryn L. Roderick

Electronic Theses and Dissertations

The present research sought to examine the effects of self-affirmation on women’s confrontation approaches following exposure to sexism. However, before examining the effects of self-affirmation, we needed a way to measure confrontation approaches. In Study 1, participants read either prototypical HATE or CARE confrontations and assessed the response. Researchers then conducted an exploratory factor analysis to create a novel scale that can assess approaches to confrontation. Study 1 also established the reliability of the HATE and CARE subscales (α = .956 and α = .929, respectively). Study 2 sought to establish the construct validity of the new measure. Study 2 …

Examining Women's Psychophysiological Responses Under Increasingly Obvious Sexism, Shelby Helwig

Electronic Theses and Dissertations

When women experience sexism, it may at first be subtle and difficult to label only becoming clearer over time. Sexism is often ambiguous in nature and experienced over an extended period; therefore, studying sexism as it occurs in daily life is crucial to extending our understanding of how women cope with discrimination. Past research has shown that women may experience maladaptive physiological responses when exposed to various forms of sexism. The current study investigated women’s cardiovascular reactivity and recovery responses to prolonged, increasingly obvious sexism. Women evaluated resumes in a mock search committee meeting with two male confederates whose statements …

Evaluating Human-Equine Interactions Through The Lens Of Adult Attachment, Clare Thomas-Pino

Electronic Theses and Dissertations

Attachment Theory suggests interaction with caregivers in childhood impacts relationships and health throughout our lives (Bowlby, 1965, 1969, 1971), leaving many who have experienced insecure attachment with an inability to form healthy relationships or cope with stressors throughout their lifespan (Holmberg, Lomore, Takacs, & Price, 2011). Horses have interacted with humans for over 12,000 years (Hintz, 1995), holding multiple roles in human society, most relying on observation by humans of equine behavior, and formation of a human-equine bond (Hamilton, 2011). More securely attached humans tend to more readily decipher non-verbal cues, positively affecting their felt security and internal working model …

Rejection Sensitivity, Relationship Quality, And Adjustment In Late-Adolescent Romantic Relationships And Friendships, Laura A. Foster

Electronic Theses and Dissertations

Rejection sensitive (RS) individuals are at greater risk for emotional maladjustment across the lifespan, with consistent links identified with depression and social anxiety. Yet little is known about interpersonal factors that may affect this association for late adolescents, especially with their romantic partners and close friends. The present study examined relationship qualities of support and negative interactions with romantic partners and friends as moderators of the link between RS and internalizing symptoms. Given the differences between male and female social relationships and experiences, these associations were expected to be further moderated by gender, with RS females in poorer quality relationships …

Letting Accuracy 'Sync' In: The Role Of Synchrony In Perceptions Of Personality Traits And Affective States, Morgan D. Stosic

Electronic Theses and Dissertations

The human propensity to synchronize their behaviors to one another seems to be an ever-present aspect of our social lives. While a breadth of approaches have been taken to explain this phenomenon, the benefit of individuals temporally aligning their behaviors to one another during an interaction remains to be precisely identified. Some have argued that by becoming synchronized to the movements and actions of another, one may become a better perceiver of that other’s internal attributes (Hoehl et al., 2021). The purpose of the present thesis was to explore this potential benefit of synchrony by examining its relation to one’s …

'Real Men' Don't See Pain, Margaret J. Gautrau

Electronic Theses and Dissertations

There is a long-standing tradition of men being held to an unobtainable “man enough” standard of masculinity. Our societal conditioning of men to be emotionless, tough, aggressive and anything-but-feminine through the social punishments of being called a “pussy,” “soft,” or told to “man up” has created an inflexibility for what it means to be a man. The purpose of this study is to capture men’s accuracy in perceiving the pain of masculine as compared to feminine targets when the targets are observed in tourniquet pain procedure. Participants observed ten videos of women and ten videos of men experiencing the tourniquet …

Individual Differences And Ecological Validity Of Emotion Regulation In Response To Sadness, Colin M. Bosma

Electronic Theses and Dissertations

The majority of research on emotion regulation processes has been restricted to controlled laboratory settingsthat use experimental paradigms to investigate short-term outcomes (Berking & Wupperman, 2012). A true understanding of emotion regulation requires an unobtrusive, ecologically valid assessment of the construct as it naturally unfolds in the environment. Digital phenotyping, or moment-by-moment quantification of individual-level human behavior using data from smartphone sensors (Torous & Onnela, 2016), is a novel method for evaluating human behavior in naturalistic settings. The present project is the first to implement digital phenotyping in the investigation of emotion regulation.

The central aim of the study was …

The Military Uniform's Impact On Patient Trust And Disclosure In Patient-Provider Interactions, Jessica Correale

Electronic Theses and Dissertations

Beyond a provider’s interpersonal skills, static cues such as a provider’s attire can greatly impact patient impressions. Attire has been found to be an important early determinant of patient confidence, trust, and satisfaction (Petrilli et al., 2015). While previous literature has investigated the impact of providers in white coats, limited studies have looked at the impact of military uniforms. This is an important research question as providers in military treatment facilities always wear their military uniforms. Additionally, service members suffer from high rates of PTSD and depression (Novotney, 2020). Beyond overcoming the initial stigma to make an appointment, disclosure is …

The Effect That Testing Has On Nondeclarative Memory, David Smith

Electronic Theses and Dissertations

Testing has been shown to improve long-term memory retention by decreasing the amount of material forgotten, a phenomenon known as the testing effect. This positive impact of testing has been shown using direct tests of memory that require declarative memory, things like memorizing word-pairs and single-word lists. This dissertation is the first research to investigate how testing impacts nondeclarative memory using three experiments. The first and second experiment utilize the word fragment completion task to measure the effect that testing has on words learned via methodology thought to recruit either declarative or nondeclarative memory. The third experiment utilizes a probabilistic …

Stress, Social Problem Solving, And Irritable Bowel Syndrome: A Cross-Lagged Panel Design Investigation Of Interactive Influences, Natalie M. Roy

Electronic Theses and Dissertations

The current study examined the interplay of three key variables: stress, maladaptive social problem-solving (SPS), and Irritable Bowel Syndrome (IBS) symptom severity. According to SPS theory, SPS is the self-directed cognitive and behavioral process by which individuals attempt to manage real-life problems or stressful situations. There are two main types of SPS: adaptive or maladaptive (D’Zurilla & Chang, 1995). Individuals who have adaptive SPS tendencies tend to view problems in an optimistic light; they perceive problems as solvable challenges and opportunities for personal growth. On the other hand, individuals who have maladaptive SPS tendencies often see problems as threatening and …

The Relationship Between Non-Suicidal Self-Injury And Suicidal Ideation: The Role Of Emotion Reactivity And Negative Problem Orientation, Victoria Quiñones

Electronic Theses and Dissertations

Research suggests that non-suicidal self-injury (NSSI) precedes and increases risk for suicidal thoughts and behaviors, but the reasons for this are not understood (Hamza et al., 2012). The trajectory from NSSI to suicidal thoughts and behaviors likely reflects a complex interaction of emotional, cognitive, and physiological factors. Indeed, research indicates that the way individuals react to emotional experiences (i.e., emotion reactivity) and approach problem solving confers risk for NSSI and suicidal thoughts and behaviors. The current study proposed an integrated model to test whether emotion reactivity (self-report and electrodermal activity) mediates the relationship between NSSI history and suicidal ideation (SI), …

Affective, Physiological, And Cognitive Response To Imagery- And Verbally-Based Rumination And Distraction In Adolescence, Hannah Lawrence

Electronic Theses and Dissertations

To date, rumination and interventions for rumination have largely been verbal in focus. Rumination has been conceptualized as dwelling on negative affect in the form of verbal thought, and interventions aim to interrupt cycles of rumination using verbal strategies. Yet, emerging evidence suggests that many individuals dwell on negative affect in the form of imagery (e.g., Lawrence, Haigh, Siegle, & Schwartz-Mette, 2018) and that imagery-based interventions may be even more effective (e.g., Arntz, 2012). This is not surprising as imagery is more affectively arousing (Holmes & Mathews, 2010), physiologically stimulating (Vrana, Cuthbert, & Lang, 1986), and realistic/vivid (Mathews, Ridgeway, & …

Conversations With The Oregon Trail And The Silent Generation, Jose A. Camacho Quiroz

Electronic Theses and Dissertations

The aim of this thesis is to explain the reason behind my art practise and process as it stands in August 2020, its context and relation to my life and experience as an outsider in the American culture. This process culminates in the documentation of experiences through the use and preparation of displays of personal artifacts as physical evidence and mechanisms of my transformation to my american persona through a continuing acculturation process and drift from the american generational archetype.

It is important to outline my current work state diverges from my past work since it no longer serves a …

Fostering Climate Change Resilience: A Socio-Ecological Forest Systems Approach, Alyssa R. Soucy

Electronic Theses and Dissertations

As climate change continues to impact socio-ecological systems, those that rely on natural resources are highly sensitive to climatic changes. Maine’s forest industry provides for the economic and social well-being of many residents and is especially vulnerable to climate change impacts. Changes in growing season length and timing, forest health threats imposed by insects and pathogens, extreme weather events, shifting forest composition, and changes in natural disturbance severity and frequency have already begun, and are projected to continue, to impact forest systems in the Northeastern U.S. While climate change presents a threat to forest systems, opportunities also arise due to …

Human-Giraffe Interactions: Characterizing Poaching And Use Of Parts As A Threat To Giraffe In Northern Kenya, Kirstie Ruppert

Electronic Theses and Dissertations

Giraffe (Giraffe spp.) are iconic wildlife species to Africa, yet relatively little conservation funding and research have been directed at protection of giraffe in the wild. A growing number of national governments and conservation organizations are implementing management strategies to address the threats that giraffe face. To inform these plans, there is a need for social science that examines the human pressures associated with decline of giraffe populations, including poaching and the use of giraffe parts. As the large majority of reticulated giraffe (Giraffa reticulata) range occurs outside formally protected areas, conservation plans must be made with …

Battle Over Black Bears: Investigating Perceptions Of The Black Bear Hunting Referendums In Maine, Francesca A. Gundrum

Electronic Theses and Dissertations

Human dimensions of wildlife is an emerging discipline that seeks to understand the complex relationships between people, wildlife, and their conflicts and/or interactions (Decker, Riley, & Siemer, 2012). Human dimensions utilizes several tested theoretical frameworks to investigate these complexities, such as cognitive hierarchy theory and wildlife value orientations (WVOs). Both of these theoretical frameworks were examined in this study, which investigated the content of news media during controversial American black bear (Ursus americanus) hunting referenda in Maine, and key stakeholder perceptions of black bear management. Maine is the only state that allows hunters to take a black bear over bait, …
