The Dual Process Model Of National Identification: Harmonious And Dangerous Worldviews As Antecedents Of National Attachment And Glorification, Stylianos Syropoulos

Masters Theses

Worldviews can shape the way in which we perceive the world. They can also shape the way in which we identify with our ingroup. Conceptualizing national identification as national attachment and glorification, four studies (total N = 1795) tested the association between endorsement of a harmonious or a dangerous worldview and national identification. Study 1 established the harmonious worldview and refined the dangerous worldview scale. Study 2 examined these relationships correlationally, and highlighted the prejudicial ideologies of right wing authoritarianism (RWA) and social dominance orientation (SDO) as mediators to this association. Study 3 examined this relationship longitudinally, across the span …

Mobile Technology Use And School Readiness In Low-Income Preschoolers, Trina M. Harmon

Masters Theses

Once a luxury, mobile devices are now utilized by most members of society, including those in even the poorest communities. Unfortunately, little research has examined the effects of mobile media use in young children, and even less on young children from low-SES communities. Past research on television, and preliminary research on mobile technology, suggests that mobile media may affect school readiness, and that the direction and strength of this relation could depend on the content and context of the use. The current study examined the relation between mobile media use and a composite school readiness measure that included preliteracy, emergent …

Narrative Communication: How Sending And Receiving Impact Statements On Past Ingroup Suffering Influences Conflict Attitudes, Brooke Burrows

Masters Theses

In the aftermath of mass violence or harm perpetrated against one group by another, commemoration or memorialization processes held by the victim group are often a space in which narratives of impact and suffering are expressed and shared. While there may be no formal or direct calls for justice or policy during these commemoration processes, prior research indicates that such public forums, ranging from truth commissions to museum exhibits, may have diverse impacts on individual emotions as well as attitudes towards the broader conflict implicated (Humphrey, 2000; Reeves & Heath-Kelly, 2020). The current work proposes a closer examination of such …

The Impact Of Social Distancing And Loneliness On Adolescents' Mental Health During Covid-19, Marielena Barbieri

Masters Theses

The COVID-19 pandemic has severely limited physical interaction (e.g., school closures, 6ft- distances, quarantine) and disrupted the daily lives of adolescents which likely heightened levels of perceived loneliness and internalizing symptomology. Due to the novelty of social distancing regulations caused by COVID-19, little is known about the role that loneliness plays in the association between stress from social distancing regulations and adherence to these regulations, and later difficulties with internalizing symptoms. The current study examined the impact of social distancing regulations on adolescents’ wellbeing through perceived loneliness by using data from a 5-week longitudinal survey-based study conducted on parents and …

Therapist-Level Moderation Of Within- And Between-Therapist Process-Outcome Associations, Alice E. Coyne

Doctoral Dissertations

Objective: Although higher-quality patient-therapist alliance and more positive patient outcome expectation (OE) consistently predict improvement in psychotherapy, most research has failed to capture the inherent nuance in these process-outcome relations by parsing them into within-therapist (i.e., differences between patients treated by the same therapist) and between-therapist (i.e., differences between therapists’ average process/outcome ratings across all patients in their caseloads) components. Moreover, the few studies that have done so have produced mixed results, suggesting the possibility of systematic variability in these associations (i.e., moderators). One potential source of such variability could be providers themselves; that is, different therapists could use these …

Early Development Of Adhd And Odd Symptoms From The Toddler To Preschool Years, Hallie Brown

Doctoral Dissertations

ADHD and ODD are common and impairing externalizing disorders in childhood that are often comorbid. Understanding the development of these symptoms when they first emerge is crucial for better identifying children who are at-risk for later impairment. Parents (N = 273) were recruited via Amazon’s Mechanical Turk to complete surveys about their 2-year-old, followed by surveys every six months for two years. Children’s general pattern of ADHD and ODD symptom growth were examined with latent class analyses. Temperament traits were subsequently added as covariates. Dual group-based trajectories and cross-lagged analyses examined the co-development of these disorders. Results showed 4 distinct …

Neural Precursors Of Apathy And Depressive Symptoms In Amnestic Mild Cognitive Impairment, Molly A. Mather

Doctoral Dissertations

Depressive symptoms and apathy are common in amnestic mild cognitive impairment (aMCI) and are associated with increased risk of conversion to Alzheimer’s disease (AD). The shared neuropathological model of neuropsychiatric symptoms (NPS) in AD suggests that symptoms of depression and anxiety represent noncognitive manifestations of neuropathological changes. Neurodegeneration in aMCI occurs in areas of the brain that support emotion regulation, including the limbic system and prefrontal control regions. Depression and apathy in aMCI have been linked to atrophy in the limbic system and prefrontal cortex and reduced connectivity in resting-state networks. However, it is not yet established whether neural changes …

The Benefits Of Spatial Separation On The Cortical Representations Of Speech Sounds, Benjamin H. Zobel

Doctoral Dissertations

Spatial separation between competing speech streams reduces their confusion (informational masking) and improves speech processing under challenging listening conditions. The precise stages of auditory processing and the bottom-up and top-down mechanisms involved in this spatial release from informational masking are not fully understood. Event-related potentials (ERPs) were used to measure the cortical processing of relevant speech under conditions of informational masking and its spatial release, and to examine the preattentive and attentive mechanisms that benefit listeners. Participants were asked to detect noise-vocoded target speech presented with noise-vocoded two-talker masking speech. In separate conditions, the same set of targets were spatially …

Effects Of Interracial Contact On University Students' Perceptions Of Inclusion, Cierra Abellera

Masters Theses

Research from higher education and social psychology has recognized feelings of belonging and perceptions of inclusion as important factors within the university student experience. Yet little research has examined the extent to which interracial contact may correspond with belonging and inclusion in the university setting. In the present study, I conduct secondary analyses of a 2016 campus climate survey of undergraduate students to examine the associations between interracial contact and three indicators of belonging and inclusion (e.g., feeling a sense of belonging, perceiving the campus to be welcoming, perceived university commitment to inclusion) among undergraduate students from different racial and …

Parental Conflict In The Context Of Multiethnoracial Relationships, Christina A. Rowley

Masters Theses

The percent of families with parents from different racial or ethnic backgrounds has risen exponentially in the last decades. Approximately 14% of children were born into multiethnoracial (MER) families in the United States in 2015, more than double the rate from 1980 (Bialik, 2017). Studies show that MER couples are more likely to separate or divorce than their monoethnoracial (MoER) counterparts, perhaps due to greater conflict stemming from differing values, coping strategies, and conflict management styles and decreased access to family and community support (Fu, Tora, & Kendall, 2001; Zhang & Van Hook, 2009). With the growing rates of MER …

The Influence Of Victim Gender And Emotional Expression In Victim Impact Statements On Legal Judgments And Punishment Decisions, Hannah Chimowitz

Masters Theses

Victim impact statements (VISs) are written or oral statements detailing the effects a crime has had on a victim. While the practice of having victims present VISs at sentencing hearings has generated much debate for over 25 years, the effects of this practice on victims, defendants, and legal decision-makers remain poorly understood. Prior research suggests that a victim’s emotional expression can affect how victims are perceived, and the legal judgments made in response to their statements. The current research considers how the effects of victims’ emotional displays on sentencing decisions might be conditioned by victim gender. Using audio-recorded VIS stimuli, …

Exploring The Relationship Between School Organizational Health, Advice Seeking Networks, And Student Behavior, Abbey M. Nachman

Doctoral Dissertations

The purpose of this study was to explore the relationship between organizational health and advice seeking behavior of school staff around students exhibiting social, emotional, or behavioral concerns. School staff are front line responders to mental/behavioral health issues and it would benefit schools to better understand the organizational factors that influence advice seeking behavior and the affect that school climate amongst teachers has on student behavior. This study investigated the climates and communication patterns of two urban elementary schools. Social network analysis was used to visualize and analyze both schools’ respective networks. School staff completed the Organizational Health Inventory as …

Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen

Doctoral Dissertations

In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …

Visual, Lexical, And Syntactic Effects On Failure To Notice Word Transpositions: Evidence From Behavioral And Eye Movement Data, Kuan-Jung Huang

Masters Theses

Evidence of systematic misreading has been taken to argue that language processing is noisy, and that readers take noise into consideration and therefore sometimes interpret sentences non-literally (rational inference over a noisy channel). The present study investigates one specific misreading phenomenon: failure to notice word transpositions in a sentence. While this phenomenon can be explained by rational inference, it also has been argued to arise due to parallel lexical processing. The study explored these two accounts. Visual, lexical, and syntactic properties of the two transposed words were manipulated in three experiments. Failure to notice the transposition was more likely when …

Multiple Identities In Sport Fandom: Balance, Conflict, & Negotiation, Aaron Mansfield

Doctoral Dissertations

Simultaneous to the sport industry’s ascent, obesity has become an issue of growing societal concern. Scholars have explored the role of social-psychological identification in both fandom and physical health, but have not yet explored the intersection of the two. Throughout life, individuals must negotiate all of their identities, including their attachment to sport teams, yet understanding of role identity within sport management is limited. Likewise, scholars have noted the need for greater illumination of the relationship between fandom and physical well-being. I address these gaps through three studies. In Study One, I completed semi-structured interviews with individuals who consider both …

Really, You Should Be Thanking Us: Paternalism And Instrumental Gratitude Expectations, Greg Larsen

Doctoral Dissertations

Intergroup helping is sometimes motivated by paternalistic narratives about recipients being incapable of making good choices. Five studies investigated whether paternalistic perceptions of recipients encouraged members of groups that provide help expect gratitude from recipients, and whether receiving gratitude and affirmation from recipients was rewarded when it was given. I first found preliminary evidence that paternalistic perceptions of recipients affects the way that members of a helper group respond to recipients’ responses to help (Study 1). I then found that believing paternalistic narratives about recipients did increase participants' expectations that recipients should show them gratitude, and that these expectations did …

Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm

Doctoral Dissertations

Mental fatigue causes an increase in task-based EEG theta and alpha power and a decrease in performance (for a review, see Tran et al., 2020). However, little is known about the emergence of mental fatigue in resting state EEG recordings and whether the progression of mental fatigue over time is influenced by individual differences. The current dissertation examined the utility of resting state EEG as a measure of mental fatigue by testing whether EEG power changed in young adults over the course of a cognitively demanding battery of tasks. The current dissertation also tested how this measure of mental fatigue …

Experience With Difficult Target Discrimination Makes Search Less Efficient: An Analysis Using Eye Movements, Junha Chang

Doctoral Dissertations

Recent studies demonstrate that experience influences observers’ strategic attentional guidance in visual searches. The current study explored how experience with difficult target color discrimination influences search strategy. Two participant groups were compared through seven dual-target search experiments: A hard search experience group and an easy search experience group. The easy search experience group performed only the easy color discrimination trials in which the two targets were easily distinguishable from distractors in the color dimension. The hard search experience group performed the same easy discrimination trials in half of the trials. The other half were difficult color discrimination trials in which …

Slow Wave Sleep In Naps Supports Episodic Memories In Early Childhood, Sanna Lokhandwala

Masters Theses

Naps have been shown to benefit declarative memories in early childhood. This benefit has been associated with sleep spindles during the nap. However, whether young children’s naps and their accompanying physiology benefit other forms of declarative learning is unknown. Using a novel storybook task, we found performance was better following a nap compared to performance following an equivalent interval spent awake. Moreover, performance was better the following day if a nap followed learning. Further, change in post-nap performance was positively associated to the amount of time spent in slow wave sleep. This suggests that slow wave sleep in naps may …

Children's Understanding Of Compositionality Of Complex Numerals, Jihyun Hwang

Masters Theses

Counting is the first formal exposure for children to learn numerals, which are constructed with a set of syntactic rules. Young children undergo many stages of rote-memorization of the sequence and eventually count through 100. What core knowledge is necessary to expand their number knowledge to higher numbers? The compositionality of numerals is a key to understanding the natural number system as in learning languages. Higher numbers (e.g., two hundred five) are constructed with the lexical items such as earlier numbers (e.g., one to nine) and multipliers. If children develop their understanding of the compositionality of numerals, they might comprehend …

Differential Harsh Parenting And Sibling Differences In Conduct Problems: The Role Of Effortful Control, Yelim Hong

Masters Theses

Differential parenting has been shown to be an important correlate and possible cause of positive and negative adjustment of sibling children. However, it is not known whether sibling differences in temperament affect this link between differential harsh parenting and sibling differences in adjustment outcomes. The current study addressed this gap in knowledge. The sample included 92 monozygotic (MZ, 63% female) twin pairs and 137 dizygotic same-sex (DZ, 52% female) twin pairs who had complete temperament survey data collected near the third annual wave in the longitudinal study. Children were 6.09 years old (SD = .69) years old at wave 1. …

The Effects Of Predictability And Stimulus Quality On Lexical Processing: Evidence From The Coregistration Of Eye Movements And Eeg, Jon Burnsky

Masters Theses

A word’s predictability has been shown to influence its processing. Two methodologies have demonstrated this time and again: eye tracking while reading and Event Related Potentials (ERPs). In eye tracking while reading, words that are made predictable by their contexts (as operationalized by the cloze task; Taylor, 1953) receive shorter first fixation times (Staub, 2015, for a review) as well as shorter gaze duration and increased skipping rate. In ERPs, the N400 component’s amplitude has also been shown to inversely correlate with a word’s predictability (Kutas and Federmeier, 2011, for a review). Despite the similarities, there is much reason to …

Studies On High-Throughput Single-Neuron Rna Sequencing And Circadian Rhythms In The Nudibranch, Berghia Stephanieae, Thi Bui

Masters Theses

One of the goals of neuroscience is to classify all of the neurons in the brain. Neuronal types can be defined using a combination of morphology, electrophysiology, and gene expression profiles. Gene expression profiles allow differentiation between cells that share similar characteristics. Leveraging the advantage of Berghia stephanieae (Gastropoda; Nudibranchia), which has around 28,000 neurons, I constructed high-throughput single-neuron transcriptomes for its whole brain. I produced a single-cell dissociation protocol and a custom data analysis pipeline for data of this nature. Around 129,000 cells were collected from 18 rhinophore ganglia and 20 circumesophageal ring ganglia (brain), consisting of the cerebropleural, …

Getting The Message Across: Flexitarians As Messengers For Meat's Climate Change Impacts, Joel Ginn

Masters Theses

Meat consumption has been a prominent part of humanity’s dietary culture, particularly in modern, Western developed nations. However, recent research has shown that collectively reducing our consumption of animal products can have major benefits for mitigating our environmental footprint. Despite a consensus among climate scientists on its potential impact, the public does not recognize the effectiveness of this behavioral shift. Recent efforts to address this have created movements and organizations that focus on reduction of meat consumption (e.g. flexitarianism, reducetarianism, Meatless Mondays), rather than elimination of meat consumption (e.g. vegetarianism, veganism) with the intent of creating a more acceptable message, …

Environmental Decision-Making, Ezra Markowitz

Sustainability Education Resources

Over the past 30 years, there has been a growing recognition amongst environmental advocates, resource managers, policymakers and researchers that the underlying cause of most environmental, conservation and sustainability issues is human behavior. As NRC and ENVIRSCI majors, you have received extensive technical training in how natural systems operate yet relatively little training when it comes to influencing or understanding how people make environmental decisions that affect those natural systems. Recognizing the fundamental role that human decision-making plays in shaping the environment reveals a new set of tools and approaches for both understanding the challenges we face and confronting those …

Maltreatment And Brain Development: The Effects Of Abuse And Neglect On Longitudinal Trajectories Of Neural Activation During Risk Processing And Cognitive Control, Jungmeen Kim-Spoon, Toria Herd, Alexis Brieant, Kristin Peviani, Kirby Deater-Deckard, Nina Lauharatanahirun, Jacob Lee, Brooks King-Casas

Psychological and Brain Sciences Faculty Publication Series

The profound effects of child maltreatment on brain functioning have been documented. Yet, little is known about whether distinct maltreatment experiences are differentially related to underlying neural processes of risky decision making: valuation and control. Using conditional growth curve modeling, we compared a cumulative approach versus a dimensional approach (relative effects of abuse and neglect) to examine the link between child maltreatment and brain development. The sample included 167 adolescents (13?14 years at Time 1, 53 % male), assessed annually four times. Risk processing was assessed by blood-oxygen-level-dependent responses (BOLD) during a lottery choice task, and cognitive control by BOLD …

Positive Youth Development: Parental Warmth, Values, And Prosocial Behavior In 11 Cultural Groups, Concetta Pastorelli, Antonio Zuffianò, Jennifer E. Lansford, Eriona Thartori, Marc H. Bornstein, Lei Chang, Kirby Deater-Deckard, Laura Di Gunta, Kenneth A. Dodge, Sevtap Gurdal

Psychological and Brain Sciences Faculty Publication Series

The current cross-cultural study aimed to extend research on parenting and children's prosocial behavior by examining relations among parental warmth, values related to family obligations (i.e., children's support to and respect for their parents, siblings, and extended family), and prosocial behavior during the transition to adolescence (from ages 9 to 12). Mothers, fathers, and their children (N = 1107 families) from 8 countries including 11 cultural groups (Colombia; Rome and Naples, Italy; Jordan; Kenya; the Philippines; Sweden; Thailand; and African Americans, European Americans, and Latin Americans in the United States) provided data over 3 years in 3 waves (M-age of …

Parenting Group For Externalizing Youth With Side Benefits For Parents, Diane Johnson

Doctor of Nursing Practice (DNP) Projects

Abstract

Background/Purpose: Mental health problems in the form of externalizing behaviors in children continues to climb. The financial burden, along and increased risks of long-term adverse effects, are a critical area that are improved with interventions such as parent management training (PMT). PMT is an evidence-based treatment for disruptive and externalizing child behaviors. Even brief interventions can improve parents’ perceptions of challenging behavior and benefit parental well-being through stress reduction and self-efficacy. Purpose: To provide PMT concepts through a group format and improve parental perceptions of externalizing behaviors and stress reduction. Methods: Provide a six-session parent group with discussion, video, …

Processes Linking Socioeconomic Disadvantage And Neural Correlates Of Cognitive Control In Adolescence, Alexis Brieant, Toria Herd, Kirby Deater-Deckard, Jacob Lee, Brooks King-Casas

Psychological and Brain Sciences Faculty Publication Series

Socioeconomic status (SES) is broadly associated with self-regulatory abilities across childhood and adolescence. However, there is limited understanding of the mechanisms underlying this association, especially during adolescence when individuals are particularly sensitive to environmental influences. The current study tested perceived stress, household chaos, parent cognitive control, and parent-adolescent relationship quality as potential proximal mediators of the association between family SES and neural correlates of cognitive control. A sample of 167 adolescents and their primary caregivers participated in a longitudinal study across four years. SES was indexed by caregivers? education and income-to-needs ratio at Time 1. At Time 2, adolescents reported …
