Discounting Of Delayed And Probabilistic Outcomes Across The Adult Lifespan, Haoran Wan

Arts & Sciences Electronic Theses and Dissertations

Intertemporal and risky decision-making predicts many problem behaviors that also decline with age, raising the question: Do intertemporal and risky decisions change with age? Despite the theoretical and empirical importance, the literature under both rubrics reveals inconsistent findings. Some studies suggest that these inconsistencies may be due to the presence of unassessed demographic differences. The present study examined age differences, evaluating the role of demographic variables in intertemporal and risky choice of gains and losses using the discounting framework. Four experiments were conducted, each with one of the four types of discounting: discounting of delayed gains, discounting of delayed losses, …

Ambivalent Images, Beloved Objects: Building Bridges Between Picture Books And The Tangible World, Danielle Ridolfi

MFA in Illustration & Visual Culture

"Ambivalent Images, Beloved Objects" examines how pedagogical theories prioritizing objects and direct sensory experiences in early childhood can be applied to the creation of picture book illustrations. In doing so, it positions picture books as educational tools, and advocates for the importance of using them not to recreate nature, but to connect readers with the tangible world of natural and human-made objects that our digital-driven culture eclipses. It strives towards a unifying pedagogical and aesthetic philosophy that accomplishes what illustrator Eric Carle characterizes as a bridge between the tactile world of objects and the world represented in illustrations.

Conceptual Understanding Of Skin Color Inheritance Among Immigrant Children And Adults, Fateme Mohseni

Arts & Sciences Electronic Theses and Dissertations

Previous research on White American children and adults' perception of skin color inheritance found that they expect inheritable properties like skin color to have a greater range of possible outcomes compared to deterministic events like mixing two paints (Schwarzlose et al., 2021). However, it is unclear whether this generalizes to other populations. To address this gap, two studies explored this question with a non-White immigrant population of children and adults. To test individuals' skin color biases, in Study 1 children and adults from immigrant populations in the U.S. were asked to predict a biracial baby's skin color (a socially relevant …

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, …

Testing Candidate Cerebellar Presymptomatic Biomarkers For Autism Spectrum Disorder, Zoe Wilson Hawks

Arts & Sciences Electronic Theses and Dissertations

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder diagnosed on the basis of social impairment, restricted interests, and repetitive behaviors. Contemporary theories posit that cerebellar-mediated error signaling impairments contribute to the causation of ASD. However, the relationship between infant cerebellar functional connectivity (fcMRI) and later ASD behaviors and outcomes has not been investigated. Such work is critical to establish early (presymptomatic) cerebellar correlates of ASD. Methods: Data from the Infant Brain Imaging Study (n=94, 68 male) were used to evaluate cerebellar fcMRI as a presymptomatic biomarker for ASD. Specifically, brain-behavior associations were analyzed for 6-month cerebellar connections in relation …

Parental Psychological Distress After Prenatal Diagnosis Of Congenital Heart Disease: Patterns, Predictors, And Impact On Early Outcomes., Kathryn Mangin-Heimos

Arts & Sciences Electronic Theses and Dissertations

Congenital heart disease (CHD) is the most common birth defect and is often diagnosed during pregnancy. The transition to parenthood after prenatal diagnosis can be particularly challenging. Both mothers and fathers are at elevated risk for psychological distress, yet early distress frequencies and patterns have not been well characterized. The impact of psychological distress on parents’ perceptions of their readiness to care for their infant after hospital discharge is currently unknown. The association of psychological distress with early infant neurodevelopment has also been under investigated. To examine these gaps in knowledge, we conducted a single center, prospective cohort study of …

Picky Eating In Children: Associations With Iq And Executive Functioning, Ara Nazmiyal

Senior Honors Papers / Undergraduate Theses

Picky eating is an under-researched behavior in children. The current study aims to assess what behaviors correlate with picky eating to better understand potential risk factors for Anorexia Nervosa. 111 children were evaluated at 5 and 6 years old, and a subset was evaluated again at 7 and 8 years old (n=36). Executive function and IQ were evaluated using parent reports and behavioral measures at baseline. Picky eating was reported by a parent questionnaire. Results showed deficits in shifting to be a predictor of higher picky eating behaviors at ages 5-6 years. Additionally, children who were reported extremely picky eaters …

Refining The Characterization Of Causation In Early Childhood Neuropsychiatric Conditions: Nature, Nurture, And Time, Rachael Elizabeth Wagner

Arts & Sciences Electronic Theses and Dissertations

Understanding causal factors in the development of early childhood neuropsychiatric conditions is essential for an understanding of disease mechanisms and therapeutic approaches. Yet the lack of objective classification of psychiatric diagnoses, phenotypic and genetic heterogeneity, pleiotropy, and extensive comorbidity have posed immense challenges to the acquisition of knowledge regarding neuropsychiatric disease etiology. While it is unequivocally established that nearly all psychiatric conditions are substantially heritable, non-genetic factors do play a role in the development of psychopathology. This thesis explores both genetic and environmental contributors to neuropsychiatric conditions in an attempt to refine the characterization of some of these risk factors. …

Children's Perceptions Of Status At The Intersection Of Race And Gender, Grace Reid

Arts & Sciences Electronic Theses and Dissertations

By 6 years of age, children associate males with higher status than females (Liben, Bigler & Krogh, 2001), and Whites with higher status than Blacks (Bigler, Averhart & Liben, 2003). However, little is known about how race and gender interact to influence children’s thinking about status. In Study 1, we asked whether children associate White men with higher status than other races and genders. Sixty children selected from among Black and White male and female targets the person who they thought would do familiar and novel jobs that varied in status. White men were the most likely to be chosen …

Young Children’S Knowledge About The Role Of Print In Reading, Molly Farry-Thorn

Arts & Sciences Electronic Theses and Dissertations

Children begin to learn about the print in books and the role it plays in reading well before the onset of formal literacy instruction. Young children’s knowledge about precisely what readers are reading when they read books and who is able to read books has been studied primarily through interviews, but conclusions from this research are limited by methodological concerns. Three experiments examined whether pre-readers understand what part of a book is read and whether they distinguish between the skill of reading and the activity of reading. Although pre-readers were typically able to locate the print in a book, they …

Double Trouble: How Children And Adults Decide When To Use Double Consonants, Ruth Caputo

Arts & Sciences Electronic Theses and Dissertations

Consonant doubling is a difficult pattern in the English writing system to master because it is inconsistent. In English two-syllable words, consonants are typically doubled after short vowels, a phonological context, but not after any vowel spelled with more than one letter, a graphotactic context. Knowledge about these contexts may help children learn when to use a single or double consonant. Previous theories on spelling development argue that children learn to spell in stages, without learning about phonological or orthographic context until late in the learning process. This study builds on previous research suggesting that children learn spelling patterns through …

Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga

Arts & Sciences Electronic Theses and Dissertations

Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …

Children Shouldn't Play With Dead Things, Sarah Adcock

Graduate School of Art Theses

I view my creative process as alchemy, the transformation of materials through experimentation. I use wax as a material that transcends its historical use as a sculptural process for casting and instead, use it for its transmutable qualities to inform content. Because of its plasticity and duality as fragile and resilient, wax is symbolically submissive and assertive. By applying heat, wax can be molded and formed into new shapes. Once it cools, wax reverts back to its natural state; solid and impermeable. I use objects to explore desires of origin and life. Transitional objects, the first “me not me” possession …

Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck

Arts & Sciences Electronic Theses and Dissertations

Across the lifespan, personality changes in normative ways, but the source of such change remains ambiguous. Life events may be one impetus of such change, but strong selection effects into such events makes it unclear whether such change is driven by already existing differences (selection) between people or socialization following life events. In a preregistered study, we test socialization and selection effects of the Big 5 and life events using a large (N = 19,627) representative sample of Germans and 12 life events (e.g. marriage, retirement) from the GSOEP. Using propensity score matching and Bayesian multilevel growth curve models, we …

Development Of Social Exclusion Detection: Behavioral And Physiological Correlates, Hyesung Grace Hwang

Arts & Sciences Electronic Theses and Dissertations

The present work aimed to directly test the theoretical claims about how we as human detect social exclusion using both physiological and behavioral methods across different life stages. Because feeling excluded from a group is a common human experience that starts in early childhood, this basic human need to belong or connect with others is argued to be universal and thought to have an evolutionary basis. In fact, it has been argued that the ability to detect being excluded may be present from birth and detecting exclusion occurs rapidly with little cognitive processing. Study 1 tested whether this rapid detection …

Emotion Dysregulation And Functional Connectivity In Children With And Without A History Of Major Depressive Disorder, Katherine Lopez

Arts & Sciences Electronic Theses and Dissertations

Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) may relate to the development of depression. Cortico-limbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS), Child Depression Inventory (CDI), and two resting state MRI scans. We examined rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral …

Flesh And Blood, Clayton Petras

Graduate School of Art Theses

In my work, I look for ways to visualize and document the degenerative mental disease of Parkinson’s and transform it into portrayals of the disease itself, its effects, and those it afflicts. Being a physical breakdown of the body, both popular culture and my own corporal understanding influence my interpretation and representation. This document outlines those influences and their buildup towards a shared understanding of the interests behind the work, as well as implies what the work does through these contexts.

How do we give identity to a disease that is difficult to diagnose or view on medical technology, currently …

Letter Teaching In Parent–Child Conversations, Molly Farry-Thorn

Arts & Sciences Electronic Theses and Dissertations

Societies engage in cross-generational transfers of information, enabling cultural transmission of skills such as tool use and language (Tomasello, 2001). Reading and spelling are two of the most important cultural tools that are transferred to children in modern societies. This transfer begins with informal experiences in the home and continues with formal teaching at school. One skill that is critical to a child’s success during the first years of reading and spelling instruction is decoding, which is the ability to sound out written words. Decoding ability depends, in part, on a child’s knowledge of letters (Lonigan, Burgess, & Anthony, 2000). …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Electronic Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.

Methods: Children with PKU (n = 31, mean age = 12.2 years) were …

What Do Children Know Before Spelling Phonologically? Prephonological Spellers’ Knowledge Of Writing, Lan Zhang

Arts & Sciences Electronic Theses and Dissertations

Most theories of literacy development have focused on children’s knowledge of the phonological aspect of writing. Relatively few studies have investigated children’s writing-related knowledge before they acquire alphabetic knowledge. The constructivist theory provides insights into what and how children know about other aspects of writing such as its graphic properties and symbolic function. The present study examined different aspects of the constructivist perspective. Preschool children with a mean age of 4 years and 4 months completed a spelling task and a recognition task. Participants who had not grasped conventional phoneme-grapheme correspondences in English were of primary interest. Consistent with the …

Parenting Preschoolers With Disruptive Behavior Disorders: Does Child Gender Matter?, Antonya M. Gonzalez

Undergraduate Theses—Unrestricted

Parental responses to child behavior can have an important impact on later behavioral outcomes. Children with Disruptive Behavior Disorders often engage in externalizing and disruptive behaviors, which usually elicit negative responses from parents. Boys are more frequently diagnosed with these disorders, resulting in a dearth of literature on parental responses to girls with Disruptive Behavior Disorders. Studies have found that parents react more negatively when girls engage in disruptive behavior, plausibly because it is contrary to societal gender expectations. The current study investigates this dynamic within the population of preschoolers with Disruptive Behavior Disorders. I predicted that parents would show …
