Testing Potential Correlations Between Childhood Lead Exposure And Authoritarianism In Adulthood, Kragen Anderson Jun 2026

Testing Potential Correlations Between Childhood Lead Exposure And Authoritarianism In Adulthood, Kragen Anderson

University Honors Theses

A significant body of research links lead exposure during childhood to negative effects ranging from increased impulsivity to societal level effects such as an increased likelihood of committing violent crime in adulthood. Due to exposure vectors such as lead water pipes, lead solder, lead based paints, and leaded gasoline there was significant lead exposure during childhood for large portions of the American population. This paper tested and found a statistically significant association between average population level lead exposure in childhood and likelihood of voting for candidate Trump later in life.


Profiles Of Family Engagement In Head Start, Elizabeth Jane Tremaine Jun 2026

Profiles Of Family Engagement In Head Start, Elizabeth Jane Tremaine

Dissertations and Theses

Families of young children are active participants in their child's transition to kindergarten. Head Start is designed to facilitate families' engagement in their child's learning experiences (Head Start Parent, Family, and Community Engagement Framework, 2018). This study explores family engagement in Head Start, its changes across the transition into kindergarten, and its relation to children's development of social-emotional and executive function skills.

The current study addresses limitations of previous research by relying on family perspectives of family engagement, approaching family engagement as a developmental concept, and taking a person-centered analytic approach that accounts for the multi-dimensionality of family engagement. This …


Emotion-Focused Teaching And Preschool Children's Social, Emotional, And Self-Regulatory Development, Brielle Emily Petit Jun 2026

Emotion-Focused Teaching And Preschool Children's Social, Emotional, And Self-Regulatory Development, Brielle Emily Petit

Dissertations and Theses

Contributing to the literature on supportive mechanisms for children's development of social, emotional, and self-regulatory competencies, the current study examines the contributions of emotion-focused teaching in preschool classrooms. Emotion-focused teaching is a framework used within preschool classrooms that encompasses three domains of teaching that support children's development of emotion skills—how teachers display their own emotions or emotion-related behaviors and actions (modeling), the ways they respond to children's emotional expressions (responding), and how instruction is used to inform children about emotions and related processes (instructing). More frequent emotion-focused teaching has been shown to be a …


What Kinds Of Experiences And Activities Contribute To College Students' Sense Of Purpose? A Mixed-Methods Study, Katlyn Rochelle Viers Sep 2025

What Kinds Of Experiences And Activities Contribute To College Students' Sense Of Purpose? A Mixed-Methods Study, Katlyn Rochelle Viers

Dissertations and Theses

For many young people, attending college is a core marker of the transition to emerging adulthood. Some students thrive in college while others become lost, confused, or seem to be just marking their time. Some researchers have hypothesized that one thing that can help students take advantage of their college experience is if they are firmly anchored in their own life goals and sense of purpose. The primary goal of this study is to contribute to knowledge about the role of a sense of purpose in college students' development, including not only its potential benefits to their academic functioning and …


Exploring Underrepresented Stem Undergraduates' Stem Identity Development: The Role Of Social Partners, Sandy Cerda-Lezama Sep 2025

Exploring Underrepresented Stem Undergraduates' Stem Identity Development: The Role Of Social Partners, Sandy Cerda-Lezama

Dissertations and Theses

This dissertation employs a three-study qualitative design to investigate the role of mentorship and social interaction in the identity development of racial minority undergraduate students in STEM disciplines. Grounded in Communities of Practice theory, this research amplifies student narratives to elucidate the relational and contextual factors that inform science identity, belonging, competence, and persistence in higher education. Study One draws upon interview data from fifteen participants in the BUILD program to analyze the role of recognition, particularly from expert scientists--in students' science identity development. This study aims to understand how racial and ethnic identity intersections influence the processes and impact …


Capturing Processes Of Influence In Students' Social Interactions: Examining A Two-Part Strategy To Detect Patterns Of Reinforcement In Continuous Real-Time Observations In The Classroom, James Lamar Delaney Iii Aug 2025

Capturing Processes Of Influence In Students' Social Interactions: Examining A Two-Part Strategy To Detect Patterns Of Reinforcement In Continuous Real-Time Observations In The Classroom, James Lamar Delaney Iii

Dissertations and Theses

Students' active engagement in learning activities is presumed to be influenced by their interactions with social partners in the classroom setting, like teachers and peers. For instance, statements of support or affirmation from teachers or peer group members are assumed to encourage positive behaviors for struggling students, while statements of disapproval are assumed to discourage and undermine active classroom behaviors. Extant research examining these processes typically tries to demonstrate significant interaction patterns or show influence over time by way of indirect behavioral measures, such as survey-based assessments. It is an open question whether these processes of influence can be directly …


Optimizing Boys' Motivation Over The Transition To Middle School: A Pattern-Centered Approach To Identifying Boys' Profiles Of Engagement And The Interpersonal Resources Important In Supporting Optimal Engagement Of Boys Across Sixth Grade, Brandy Anne Brennan Aug 2025

Optimizing Boys' Motivation Over The Transition To Middle School: A Pattern-Centered Approach To Identifying Boys' Profiles Of Engagement And The Interpersonal Resources Important In Supporting Optimal Engagement Of Boys Across Sixth Grade, Brandy Anne Brennan

Dissertations and Theses

There are normative declines in student engagement during the transition to middle school, and studies indicate that these challenges may be especially problematic for boys. Given the limited empirical evidence offering ways to support boys' motivation, the main goal of this study was to understand ways we can help boys reach their full potential over the transition to middle school by examining the interpersonal resources from parents, teachers, and peers that sustain boys' optimal engagement across the first year of middle school. Using data from an existing longitudinal dataset of 191 sixth-grade boys (N = 366; 52% male) in …


Stigma, Shame, And Narcissism: A Literature Review, Alex Gaither Jun 2025

Stigma, Shame, And Narcissism: A Literature Review, Alex Gaither

University Honors Theses

This thesis is a literature review of 12 peer reviewed journal articles accessible through the Portland State University library database on the relationship between stigma, shame, and Narcissistic Personality Disorder (NPD). This thesis discusses ideas brought up in these articles regarding the classification and conceptualization of NPD as a disorder, the role that shame plays in the pathology of NPD, the ways that shame is addressed through treatment, and public and practitioner held bias resulting from the stigmatization of the disorder. New and upcoming ways of conceptualizing the disorder are also briefly discussed as there has been a push to …


Impacts Of Parent Separation Within Siblings: A Literature Review, Araceli Tello Hernandez Jun 2025

Impacts Of Parent Separation Within Siblings: A Literature Review, Araceli Tello Hernandez

University Honors Theses

Parent-child separation is a growing global issue that impacts millions of families. Although there is research on how an individual child might be impacted by separation from their parents, less is known about siblings. The importance of understanding the individual first and looking at attachment theory and resilience, its role it plays. The study serves to investigate the traumatic events of parent separation through loss whether death, divorce or immigration and seeing the gaps of literature when talking about these topics. This data relies on different literature and different research that shows how a traumatizing event can impact a child's …


Youth Experiences Of Participation, Inclusion, And Influence Within A Youth-Serving Organization Implementing Participatory Processes, Rhen M. Miles Feb 2025

Youth Experiences Of Participation, Inclusion, And Influence Within A Youth-Serving Organization Implementing Participatory Processes, Rhen M. Miles

Dissertations and Theses

The youth development field has undergone shifts and reconstructions in how youth are conceived, impacting the approaches of youth-serving programs attempting to facilitate learning, growth, and engagement. Evolving views inform how policymakers, funders, and youth-serving agencies perceive and relate with youth. In turn, these dynamics influence how youth learn to think about themselves, others, and the world. Dominant discourse regarding youth development has been shifting from a deficit-based to an asset-based lens, with the proliferation of Positive Youth Development (PYD) frameworks, which seek to cultivate internal strengths and positive developmental outcomes rather than just prevent negative behaviors and outcomes. Despite …


Young Adults’ Views On Personal Death, Victor N. Soto Jan 2025

Young Adults’ Views On Personal Death, Victor N. Soto

Anthós

Within academic discussions of death and dying, there is a deficit of qualitative studies on how young adults view personal death. This article explores young adults’ (18-24) views on personal death using inductive coding of the transcriptions of three 1:1 interviews and one focus group. Soto’s findings show that young adults view their personal death in three ways: 1) they reflect on family death experiences as frames of reference for personal death, 2) they rely on a life well- lived to ease anxiety around personal death, and 3) they use humor as a coping mechanism in thinking about and discussing …


Wired For Success: A Neurobiological Approach To Improving The Academic Outcomes Of Middle School Boys, Allison Emery Aug 2024

Wired For Success: A Neurobiological Approach To Improving The Academic Outcomes Of Middle School Boys, Allison Emery

University Honors Theses

Male accomplishment in scholastic settings has been declining globally for the last decade, leading to long-term consequences for boys and men. Possible neurobiological underpinnings of the gender gap in education are discussed in this literature review. While male and female differences have, in the past, largely been considered socialized, recent science also confirms neurobiological variances between male and female development. These distinctions are assessed for their potential ties to the decline in male academic success, and are correlated to classroom practices, strategies and interventions meant to increase boys' engagement and performance.


Dynamic Social Ecologies Of Students' Motivational Resilience: The Complex Relationship Between Family, Teacher, And Peer Support, And Students' Academic Coping And Reengagement, Kristen Elizabeth Raine Jul 2024

Dynamic Social Ecologies Of Students' Motivational Resilience: The Complex Relationship Between Family, Teacher, And Peer Support, And Students' Academic Coping And Reengagement, Kristen Elizabeth Raine

Dissertations and Theses

Drawing upon self-determination theory (SDT) based models of motivational resilience, the following dissertation contains three studies that expand upon the current literature by investigating how processes of motivational resilience, or children's general capacity to handle the everyday academic stressors they encounter at school, are connected to the complex social ecologies created by the intersecting contexts of school and home. Study 1 examined whether family motivational support predicted increases in student reengagement through its effect on subsequent levels of students' self-system processes of relatedness, competence, and autonomy in a sample of 590 early adolescents from an urban middle school in the …


Faculty Mentors' Influence On Latino/A/X Stem Undergraduates' Stem Identity Development, Sandy Cerda-Lezama Mar 2024

Faculty Mentors' Influence On Latino/A/X Stem Undergraduates' Stem Identity Development, Sandy Cerda-Lezama

Dissertations and Theses

Despite Latino/a/x college student attendance rising substantially over the past decades, their graduation rates do not match the increased admission rates. In addition, Latino/a/x students are considerably under-represented in STEM. However, research suggests that when these students are encouraged by social partners to have meaningful participation and given resources such as mentoring, this eases the barriers they experience. The current study utilized interviews with 11 Latino/a/x STEM undergraduates (aged 18-29) to understand how faculty mentors influence their STEM identity development. Students shared answers about how faculty promoted and inhibited their STEM identity development through conversations about their sense of competence, …


Dissociative Identity Disorder: A Literature Review, Savannah M. Demicoli Jun 2023

Dissociative Identity Disorder: A Literature Review, Savannah M. Demicoli

University Honors Theses

Dissociative Identity Disorder (DID), previously referred to as Multiple Personalities Disorder, has been historically misrepresented in the media and excluded from professional training. This literature review describes the information presented in various research studies to illustrate what DID is, the theoretical models that have been used in application to DID, the role of childhood trauma, as well as successful treatment methods and accessibility of resources. In understanding DID, it is necessary to look at the disorder’s prevalence, background, and major symptoms of amnesia and switching between personality states. The theoretical models that will be covered include the Sociocognitive/Fantasy Model and …


The Benefits Of Outdoor Education For Students With Attention-Deficit Hyperactivity Disorder, Annabelle Winking Jun 2023

The Benefits Of Outdoor Education For Students With Attention-Deficit Hyperactivity Disorder, Annabelle Winking

University Honors Theses

ADHD diagnoses and pharmaceutical treatment have increased dramatically within this century. However, non-pharmaceutical treatments have not reflected this increase. One area where those diagnosed often struggle the most is within academic settings. This study argues for the benefit of outdoor education for students with ADHD, and suggests the importance of future research on this topic. In this study I examine the recent history of ADHD and evaluate trends in treatment, particularly green space as a form of treatment. These studies show both immediate and long-term benefits within a variety of settings. Within these studies, I identified a research gap in …


Main, Mediated, And Moderated Effects Of Participating In An After-School Social And Emotional Learning Program On Young Children's Development Of Social-Emotional Skills, Amy L. Cordier Apr 2023

Main, Mediated, And Moderated Effects Of Participating In An After-School Social And Emotional Learning Program On Young Children's Development Of Social-Emotional Skills, Amy L. Cordier

Dissertations and Theses

Young children's social and emotional skills (SE skills) are highly predictive of the ease with which they transition to kindergarten as well as their success in the K-12 school system and in life after graduation. Children from low socioeconomic status (SES) backgrounds often enter kindergarten with less well-developed SE skills and lag their peers throughout their school careers. Studies of social-emotional learning (SEL) programs indicate that these programs are successful in teaching SE skills, both in school and in after-school programs. However, less is known about the mechanisms of changes through which SEL programs improve children's SE skills and for …


Do Motives Matter? The Role Of Motivation In Shaping The Impact Of Mindfulness Training On Teachers' Psychological Distress And Wellbeing, Cristi N. Pinela Jun 2022

Do Motives Matter? The Role Of Motivation In Shaping The Impact Of Mindfulness Training On Teachers' Psychological Distress And Wellbeing, Cristi N. Pinela

Dissertations and Theses

Research on the impacts of mindfulness trainings (MTs) on teachers' psychological health and wellbeing suggests that MTs may be especially well-suited to preparing teachers for the unique demands of the profession. However, few studies have investigated whether different teachers benefit in different ways from mindfulness training, although there is some evidence that mindfulness training may yield dissociable benefits and preliminary evidence of differential effects of MTs on subgroup of teachers. The paucity of empirical evidence may be partly attributed to the paucity of theoretical frameworks that identify possible mechanisms for differential effects. The present study stepped into this gap by …


Montessori Schools: How And Why Do They Impact Student Relationships And Communication Skills?, Jacquelyn G. Zavala Jun 2022

Montessori Schools: How And Why Do They Impact Student Relationships And Communication Skills?, Jacquelyn G. Zavala

University Honors Theses

Montessori schooling, created by physician and educator Maria Montessori, is a well-known alternative to the traditional style of teaching. Many researchers have focused on how the Montessori method can produce successful and well-rounded students, not only academically, but within the social realm as well. What is less known is the extent to which Montessori impacts the social development of children and their forming of peer relationships and why it does so. After looking into and discussing the previous literature written on this topic, this thesis project utilizes reviews with two individuals with experience in the primary level Montessori setting to …


Gender Does Not Equal Genitalia: A Review Of The Implications Of Inclusivity In School-Based Sexual Health Education On The Identity Development Of Non-Binary And Transgender Adolescents, Sol N. Rise Mar 2022

Gender Does Not Equal Genitalia: A Review Of The Implications Of Inclusivity In School-Based Sexual Health Education On The Identity Development Of Non-Binary And Transgender Adolescents, Sol N. Rise

University Honors Theses

Abstinence-only based sexual education has historically been the predominant form of school-based sexuality and sexual health education in the United States since the early 1900s. In recent years, there has been an emergence of more expansive and inclusive comprehensive education, however, both types of sexual education continue to affirm hetero- and cis-centric social and cultural norms around gender and sexual identity that leave transgender and non-binary youth at increased risk of poor psychological well-being and physical health outcomes compared to their peers. There have been considerable recommendations within the discourse community for the linguistic de-gendering of anatomy and anatomical processes, …


Sustaining Boys' Motivation Over The Transition To Middle School: Can Interpersonal Resources Protect Boys From Engagement Declines Across Sixth Grade?, Brandy Anne Brennan Dec 2021

Sustaining Boys' Motivation Over The Transition To Middle School: Can Interpersonal Resources Protect Boys From Engagement Declines Across Sixth Grade?, Brandy Anne Brennan

Dissertations and Theses

Recent research has highlighted the challenges boys face in school. Boys are overrepresented on indicators of negative academic outcomes, such as detention, suspension, and dropout, as well as underperformance on state and national tests. Moreover, these effects may be long lasting: Compared to females, male students are less likely to graduate high school, enroll in college, and complete a college degree, and they may be particularly vulnerable in middle school. As students enter middle school, their motivation and engagement normatively decline, and these losses may be especially problematic for boys. Nevertheless, research documents the importance of close relationships with parents, …


Parenting And Children's Academic Coping As A Dynamic System: Feedforward, Feedback, And Mediators Of Changes Across The School Year, Kristen Elizabeth Raine Dec 2021

Parenting And Children's Academic Coping As A Dynamic System: Feedforward, Feedback, And Mediators Of Changes Across The School Year, Kristen Elizabeth Raine

Dissertations and Theses

Using a motivational framework based in self-determination theory, the present study investigated the dynamic system between parenting and children's coping, defined as the ways they handle the everyday difficulties they encounter in school, using a sample of 1,020 students in grades three through six drawn from a larger cohort-sequential study. Three overarching research questions were examined using multiple regression that concerned 1) feedforward effects from parents' initial provision of motivational support (i.e., involvement, structure, and autonomy support) to changes in children's academic coping across the school year, 2) feedback effects from children's initial coping to changes in the same parenting …


"Like I Was An Actual Researcher": Participation And Identity Trajectories Of Underrepresented Minority And First-Generation Stem Students In Research Training Communities Of Practice, Jennifer Lynn Lindwall Aug 2021

"Like I Was An Actual Researcher": Participation And Identity Trajectories Of Underrepresented Minority And First-Generation Stem Students In Research Training Communities Of Practice, Jennifer Lynn Lindwall

Dissertations and Theses

Although calls for a more diverse workforce in biomedical fields have been widespread, racial and ethnic gaps in biomedical degree attainment remain. Contextualist perspectives seek to understand persistent STEM inequities by examining person-in-context experiences and how systemic factors filter into students' proximal contexts shaping their participation and science identity trajectories. Research training communities of practice aim to offer underrepresented minority and first-generation students support, guidance, and opportunities to learn the practices of science and construct their science identity. However, many students still choose to leave these programs. There is limited research on these students' science identity construction process and their …


Music Education, Child Development, And Academic Achievement: A Review Of Recent Literature, Connor M. Welsh Jun 2021

Music Education, Child Development, And Academic Achievement: A Review Of Recent Literature, Connor M. Welsh

University Honors Theses

In this literature review, the effect of music education on child development and academic success was evaluated. The claim that music education is beneficial to both child development and academic success has grown as a popular idea in recent decades. One example of this is the popular practice of having children or infants listen to classical music. This literature review aimed to evaluate this claim by examining a sample of the past ten years of research articles. The literature review was divided into two main categories: music education and cognitive development and music education and social-emotional development. Initially, it was …


The Prevalence Of Mental Health Disorders And Deficits In Individuals With And Without Siblings, Samantha Villanueva Jun 2021

The Prevalence Of Mental Health Disorders And Deficits In Individuals With And Without Siblings, Samantha Villanueva

University Honors Theses

The goal of this thesis is to understand how having siblings could affect mental well-being in individuals. Within the framework of a literature review, I examined multiple aspects of mental well-being with regard to siblings: 1) if having siblings could be a precursor for behavioral or developmental patterns in children 2) how trauma affects only children and individuals with siblings differently 3) long-term effects of sibling count once children reached adulthood 4) biases from clinical perspectives and prevention programs to combat these. Upon conclusion, only children were often noticed to struggle with mental health and certain socialization, although researchers noted …


The Development Of Immigrants In Education, Kayla R. Guerrero Aug 2020

The Development Of Immigrants In Education, Kayla R. Guerrero

University Honors Theses

Being an essential part of American community, immigrants face several challenges as they adjust to life away from their home country. Many of those challenges begin when immigrant students start school in the United States education system. This exploratory research investigates the school experiences of immigrants and whether or not they were supported by their peers, teachers, parents, and community and how that influenced their development. Adult immigrants will reflect back on their education experience through interviews in order for the researcher to contribute a new foundation for immigrant student development research from the perspective of actual immigrants. This will …


Detecting Reinforcement Patterns In The Stream Of Naturalistic Observations Of Social Interactions, James Lamar Delaney 3rd Jul 2020

Detecting Reinforcement Patterns In The Stream Of Naturalistic Observations Of Social Interactions, James Lamar Delaney 3rd

Dissertations and Theses

How do consequences affect future behaviors in real-world social interactions? The term positive reinforcer refers to those consequences that are associated with an increase in probability of an antecedent behavior (Skinner, 1938). To explore whether reinforcement occurs under naturally occuring conditions, many studies use sequential analysis methods to detect contingency patterns (see Quera & Bakeman, 1998). This study argues that these methods do not look at behavior change following putative reinforcers, and thus, are not sufficient for declaring reinforcement effects arising in naturally occuring interactions, according to the Skinner's (1938) operational definition of reinforcers.

This study presents the conceptual and …


The Role Of Teacher Autonomy Support Across The Transition To Middle School: Its Components, Reach, And Developmental Effects, Julia Sara Dancis Jan 2019

The Role Of Teacher Autonomy Support Across The Transition To Middle School: Its Components, Reach, And Developmental Effects, Julia Sara Dancis

Dissertations and Theses

Building upon self-determination theory, this study sought to ascertain the reach of teacher autonomy support beyond its well-documented impact on student autonomy and engagement to include student competence and relatedness, as well as to parse apart specific teacher behaviors that comprise autonomy support (i.e., respect, choice, relevance, coercion) and their unique influences on the multiple motivational outcomes, surrounding the transition to middle school. These questions were examined using information from 224 fifth graders, 339 sixth graders, and 345 seventh graders attending elementary and middle schools in a predominantly Caucasian working and middle class school district.

Regression analyses, predicting change in …


Pathways To Kindergarten Growth: Synthesizing Theories Of The Kindergarten Transition To Support Children's Development, Rita Yelverton May 2018

Pathways To Kindergarten Growth: Synthesizing Theories Of The Kindergarten Transition To Support Children's Development, Rita Yelverton

Dissertations and Theses

The transition into Kindergarten is a critical time for children's development--children's patterns of academic development and engagement with school often start in Kindergarten and persist throughout their academic careers. This is a developmental period that is marked by many changes in children's lives, and therefore it is not a surprise that many children struggle during this transition. These struggles are more common for children who are living in poverty, and although there have been national initiatives to address opportunity gaps in access to early education, investigations into the effectiveness of these programs in promoting children's Kindergarten development have shown mixed …


Student Motivation Profiles As A Diagnostic Tool To Help Teachers Provide Targeted Support, Cailin Tricia Currie Jan 2018

Student Motivation Profiles As A Diagnostic Tool To Help Teachers Provide Targeted Support, Cailin Tricia Currie

Dissertations and Theses

Research has demonstrated that academic engagement is an important resource for students, promoting their learning and achievement. Less well documented is the possibility that students' classroom engagement may also be a valuable resource for their teachers, capable of influencing how teachers treat their students over time. The current study sought to examine the relationship between student motivation and teacher behavior to better understand how teachers perceive and respond to their students' classroom motivation and whether these motivational states contain diagnostic information about the types of supports students may need in order to be engaged, enthusiastic learners. The observable manifestations of …
