Characterizing Complex Affective Processing Across Age And In Relation To Social Anxiety Symptoms, M. Catalina Camacho Dec 2022

Characterizing Complex Affective Processing Across Age And In Relation To Social Anxiety Symptoms, M. Catalina Camacho

Arts & Sciences Electronic Theses and Dissertations

Humans require a shared understanding of others’ emotions for adaptive social functioning. For instance, if someone tells a joke and another person laughs, we assume the laughing person was happy because we have a shared concept for such positive interactions. Children develop and refine these concepts as they grow up, but the underlying neural processing that supports this development is unknown. Identifying the neurodevelopment underlying emotion processing could provide important insight to emotional disorders. For example, social anxiety is associated differences in the detection and interpretation of negative or neutral emotional cues, but the underlying neurodevelopment of this behavior is …


Testing Of A Novel Combined Eating-Disorder And Weight-Loss Online Guided-Self Help Intervention For Young Adults With A Binge-Type Eating Disorder And Overweight Or Obesity, Grace Elise Monterubio Dec 2022

Testing Of A Novel Combined Eating-Disorder And Weight-Loss Online Guided-Self Help Intervention For Young Adults With A Binge-Type Eating Disorder And Overweight Or Obesity, Grace Elise Monterubio

Arts & Sciences Electronic Theses and Dissertations

Binge-type eating disorders (EDs) and obesity-related health concerns are two serious medical issues, though study of their treatment has largely remained separate. This study implemented an online, guided self-help ED intervention that concurrently offered Cognitive Behavioral Therapy (CBT)-based tools to improve ED symptoms, while also teaching energy-density food principles of behavioral weight loss (BWL), for individuals with clinical/sub-clinical binge-type EDs with comorbid overweight/obesity. The study aimed to examine change in weight, change in ED symptoms, and program engagement between a combined intervention (CBT + BWL) and an ED-only intervention. Participants in the combined intervention group received weekly session content pertaining …


Interpersonal Emotion Regulation In Current And Remitted Major Depressive Disorder: An Experience Sampling Study, Yunjing Liu Dec 2022

Interpersonal Emotion Regulation In Current And Remitted Major Depressive Disorder: An Experience Sampling Study, Yunjing Liu

Arts & Sciences Electronic Theses and Dissertations

Individuals with major depressive disorder (MDD) have difficulties regulating emotion on their own. As people also turn to others for help with emotion regulation (i.e., interpersonal emotion regulation [IER]), we examined whether these difficulties extend to IER in current and remitted MDD. We generally expected individuals with current MDD (and remitted MDD to a lesser extent) to utilize IER in distinct ways compared to those with no history of psychiatric disorders (i.e., controls) due to differences in emotional, cognitive, and interpersonal functioning. Using experience sampling, adults with current MDD (n=48), remitted MDD (n=80), and controls (n=87) reported on how frequently …


An Online Vignette Study To Examine The Outcomes Of A Preclinical Alzheimer Disease Diagnosis, Matthew John Wynn Dec 2022

An Online Vignette Study To Examine The Outcomes Of A Preclinical Alzheimer Disease Diagnosis, Matthew John Wynn

Arts & Sciences Electronic Theses and Dissertations

As Alzheimer disease research forges ahead, and new potential treatments are developed, a conceptualization is emerging of a presymptomatic disease stage. This stage, known as preclinical Alzheimer disease, is characterized by the buildup of amyloid beta and tau proteins in the brain to abnormal levels in a cognitively normal person. There are unknown potential risks and benefits of communicating biological marker risk information for Alzheimer disease using the preclinical Alzheimer disease diagnostic label. The current study uses a vignette methodology to measure older adults’ understanding of risk information when presented with information regarding their risk for developing Alzheimer dementia. Participants …


Construction And Use Of Cognitive Maps In Model-Based Control, Ata Karagoz Dec 2022

Construction And Use Of Cognitive Maps In Model-Based Control, Ata Karagoz

Arts & Sciences Electronic Theses and Dissertations

When making decisions, we sometimes rely on habit and at other times plan towards goals. Planning requires the construction and use of an internal representation of the environment, a cognitive map. How are these maps constructed, and how do they guide goal-directed decisions? We coupled a sequential decision-making task with a behavioral representational similarity analysis approach to examine how relationships between choice options change when people build a cognitive map of the task structure. We found that participants who encoded stronger higher-order relationships among choice options showed increased planning and better performance. These higher-order relationships were more strongly encoded among …


Narratives Close The Gap: The Limited Role Of Temporal Distance In Binding Events Into Coherent Memories, Angelique Delarazan Aug 2022

Narratives Close The Gap: The Limited Role Of Temporal Distance In Binding Events Into Coherent Memories, Angelique Delarazan

Arts & Sciences Electronic Theses and Dissertations

Temporal information has been identified as a powerful influence on memory retrieval. Much of this arise from studies that tend to focus on associations between items. In contrast, real-life experiences consist of discrete events that encompass more than mere associations. While events can be remembered based on temporal proximity, events that are farther apart in time can also be linked together by forming a coherent narrative. Given that daily experiences are multifaceted, it is unclear to what extent prior work generalizes to real-world memories. Here, we sought to determine the influence of temporal features and narrative coherence on memory for …


A Personalized Intervention To Increase Regulatory Capacity For Anti-Racist Action, Jennifer Frances Beatty Aug 2022

A Personalized Intervention To Increase Regulatory Capacity For Anti-Racist Action, Jennifer Frances Beatty

Arts & Sciences Electronic Theses and Dissertations

Many White Americans are motivated to be anti-racist but fall short. Often, they become defensive when confronted with their involvement in perpetuating racism. To address this, we designed an experiment to test a personalized, social modeling intervention that targets obstacles to responding constructively to being confronted about racism. In our multi-faceted intervention, participants learned from videos of role models who effectively managed a confrontation after doing something racist. After each video, participants wrote personalized reflections applying what they learned. In a registered sample of 391 White Americans, the intervention increased the personal acknowledgment of racial bias, changed relevant bias-related beliefs …


A Perfect Escape: Fantasy, Place And Narrative In Adolescence, Cydney Cherepak May 2022

A Perfect Escape: Fantasy, Place And Narrative In Adolescence, Cydney Cherepak

MFA in Illustration & Visual Culture

This essay explores the realms of special places, the literary genre of fantasy, narrative, and comics. These topics are traversed alongside subjects of adolescence and the creation of stories for middle-grade readers. Framed with personal stories, as well as peaks into my process, I investigate these subjects through the lens of my own life and work, specifically my thesis project, a comic for middle-grade readers titled Beyond the Castle Walls. Beginning with adolescence in association with special places, I consider the work of developmental psychologists David Sobel and Edith Cobb as they pin-point the role of secret forts, nature, …


The Hidden Power Of Images: An Allegory Of Chaos And Performance In The Digital Age, Livia Xandersmith May 2022

The Hidden Power Of Images: An Allegory Of Chaos And Performance In The Digital Age, Livia Xandersmith

MFA in Visual Art

Within this text, I explore the hidden power of images in American visual culture through painting-based installations. I investigate images of the past and present juxtaposed in a surrealist landscape. Through the use of images in the news, entertainment, advertising, and images within the home, I depict how the problems of the past bleed into our perceptions of the present. I find that this cycle of problem inheritance connects us as humans regardless of time, generation, and place. In my work, I explore the complexity of image culture and its shifting presence within the digital age. Using surrealist collage, I …


Who Has My Back? Perceptions Of Anti-Racist And Anti-Sexist Allyship Are Predicted By Race, Gender, And Past Behavior, R. Grace Drake May 2022

Who Has My Back? Perceptions Of Anti-Racist And Anti-Sexist Allyship Are Predicted By Race, Gender, And Past Behavior, R. Grace Drake

Arts & Sciences Electronic Theses and Dissertations

After facing racial or gender discrimination, people often seek support or allyship from others. However, who will provide effective support or allyship is often uncertain. To understand how people of color and women navigate this uncertainty, in two studies we randomly assigned participants to read a series of vignettes about potential allies. In each vignette, a person was described as either Black, Asian, Hispanic, or White and either a man or woman. Participants also sometimes learned that the person had a history of allyship behavior. Participants were then asked to envision that someone made a racist (Study 1) or sexist …


The Roles Of Time And Measurement In Within-Person Purpose Variability, Gabrielle N. Pfund May 2022

The Roles Of Time And Measurement In Within-Person Purpose Variability, Gabrielle N. Pfund

Arts & Sciences Electronic Theses and Dissertations

Sense of purpose can be understood as the extent to which one feels that they have personally meaningful goals and directions guiding them through life. Though the predictive value of this construct is well-established based on the robust research illustrating that it predicts a host of desirable cognitive, physical, and well-being benefits, the nature of sense of purpose is still under-researched. In particular, little is known regarding the extent to which this construct fluctuates within an individual and what is tied to those fluctuations. The current study addresses this gap by utilizing data from four separate studies (total N = …


The Role Of Affect And Exercise Goals In Physical Activity Engagement In Younger And Older Adults, Marta Stojanovic May 2022

The Role Of Affect And Exercise Goals In Physical Activity Engagement In Younger And Older Adults, Marta Stojanovic

Arts & Sciences Electronic Theses and Dissertations

Despite potential benefits of physical activity engagement for older adults, individuals over the age of 65 were more likely to report physical inactivity compared to younger and middle-aged adults. It is extremely important to understand factors influencing regular engagement in physical activity in older adults, particularly the role of affective response and exercise goals which have been greatly overlooked. Mixed findings have been reported in terms of age differences in affective response to daily physical activity while exercise goals in younger and older adults have not been thoroughly compared. Hence, the goal of this project was to determine age differences …


Effects Of A Patient Question Prompt List On Outpatient Palliative Care Appointments, Meghan Mcdarby May 2022

Effects Of A Patient Question Prompt List On Outpatient Palliative Care Appointments, Meghan Mcdarby

Arts & Sciences Electronic Theses and Dissertations

Question prompt lists (QPLs) promote patient and care partner participation during medical appointments. The current study evaluated use of a 25-question QPL during initial outpatient palliative care appointments. I applied tenets of Social Cognitive Theory to investigate the relation between appointment participation, state anxiety, and perceived self-efficacy in the context of a QPL intervention. Participants were patients and care partners attending the patient’s first outpatient palliative care appointment at an academic hospital. Participants were randomly assigned to receive the QPL before the appointment (n = 29 appointments) or to receive usual care (n = 30 appointments). Audio recordings of appointments …


The Effect Of Social Primes On The Perception Of Native- And Nonnative-Accented Speech, Drew J. Mclaughlin May 2022

The Effect Of Social Primes On The Perception Of Native- And Nonnative-Accented Speech, Drew J. Mclaughlin

Arts & Sciences Electronic Theses and Dissertations

Listeners use more than just acoustic information when processing speech. Social information, such as a speaker’s race/ethnicity, can also affect listeners’ understanding of the speech signal. In some cases, these social primes can facilitate perception, while in others they may inhibit perception. Indeed, a picture of an East Asian face has been shown to facilitate the perception of Mandarin Chinese-accented English but interfere with the perception of American-accented English. The present dissertation builds on this line of inquiry, addressing novel topics including the generalizability and specificity of social priming effects, their relationship with implicit racial/ethnic associations, and their role in …


Extrinsic Emotion Regulation At The Global And Daily Level: Strategy Choice And Associations With Regulator Well-Being, Jiyoung Kwak May 2022

Extrinsic Emotion Regulation At The Global And Daily Level: Strategy Choice And Associations With Regulator Well-Being, Jiyoung Kwak

Arts & Sciences Electronic Theses and Dissertations

Extrinsic emotion regulation (i.e., the goal directed process of managing someone else’s emotions) can influence not only the target, but also the regulator. Through effective extrinsic emotion regulation (ER), a regulator can strengthen their relational bonds, leading to subsequent enhancement of regulator well-being at the trait and state level. The aim of this study was to examine the associations between extrinsic ER strategy use (situation modification, attentional deployment, reappraisal, suppression) and regulator well-being, and the contextual predictors of extrinsic ER in daily life. Undergraduates (N = 198) completed a trait survey assessing extrinsic ER and well-being outcomes, followed by 14 …
