The Timing Of Pubertal Onset Affects Adults Anxiety Behavior In A Sex-Specific Manner, Evan Raubenolt

Honors Projects

This study aims to look at the relationship between the timing of pubertal onset and its long-term effects on adult anxiety behavior in rats. Though the topic of pubertal onset has been frequently discussed in developmental research, its exact effects have been inconsistent. Human models have shown that early and late maturing males are associated with a notable increase in adult anxiety behavior, while in rat models, similar sex-specific effects regarding anxiety have been demonstrated, though those studies focus on a causal relationship between exposure to stress and age of pubertal onset. This study first aims to examine that relationship …

Neonatal Striatal Volume Is Associated With Infant Anhedonia, Melissa Nevarez-Brewster, Catherine H. Demers, Jessica L. Irwin, Laura M. Glynn, Martin A. Styner, Mercedes Hoeflich Haase, M. Camille Hoffman, Diego A. Pizzagalli, Benjamin L. Hankin, Elysia Poggi Davis

Psychology: Faculty Scholarship

Anhedonia is increasingly recognized as a transdiagnostic risk factor for psychopathology. New evidence demonstrates that anhedonia is present in infancy and early childhood. Structural variability in striatal regions involved in reward processing and pleasure seeking is concurrently linked to anhedonia, yet few studies have examined whether striatal differences presage anhedonia, and none have examined prospective associations before middle childhood. The present study examined whether neuroanatomical markers that confer risk for anhedonia can be detected as early as the neonatal period. Specifically, we tested whether the volume of striatal regions in neonates predicted the emergence of infant anhedonic behaviors at six …

The Speech-To-Song Illusion Across Development And The Effects Of High-Level Expectations, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical listener can readily categorize auditory stimuli as either speech or song even though these structures share many acoustic similarities. These musical and linguistic categories may nevertheless take time to develop as children acquire language- and music-specific knowledge. In the Speech-to-Song (STS) illusion, multiple repetitions of a natural spoken utterance can give rise to a perceptual switch wherein the stimulus begins to sound song-like to the listener. While the STS illusion has been well-researched in adult listeners, it had yet to be investigated in children. In our study, we examined whether children experience the STS illusion by presenting participants …

Caregiver Perceptions, Knowledge, And Likelihood To Intervene With Suicidal Youth, Amber L. Willwerth

All-Inclusive List of Electronic Theses and Dissertations

As a first step, the present study examines the invariance structure of the Faith Maturity Scale across three time points to assess the reliability and structure of the scale over time. The confirmatory factor analytic method was used to examine data from 572 college students. Configural, metric, scalar, and residual/strict models were tested. Findings support the full strict residual longitudinal invariance model, providing …

The Influence Of High Iq On Adhd Symptom Presentation And Outcomes In Children, David A. Lee

All-Inclusive List of Electronic Theses and Dissertations

Research suggests that a high intelligence quotient (IQ) may contribute to the underdiagnosis and misdiagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) in children. High IQ may allow children to compensate for executive functioning-related deficits inherent in ADHD and/or may influence behaviors such as high activity level or not following rules that mimic ADHD symptoms. To gain a better understanding of the relationship between IQ and ADHD, the present study aimed to investigate how high IQ impacts symptoms of inattention and hyperactivity as well as outcomes related to academic performance, emotional regulation, and peer relationships in children. The study utilized archival data from …

The Role Of Adolescent Depression Heterogeneity And Resilience Resources In Adulthood Cardiometabolic Health And Depressive Symptoms, Samantha R. Scott

Electronic Theses and Dissertations

Depression in adolescence is a major public health problem and is a risk factor for early-onset cardiometabolic disease. Although adolescent depression is a risk factor for poor cardiometabolic health, depression is heterogeneous and associations may differ by sex. Additionally, if risk factors such as depression can predict adulthood cardiometabolic health, resilience factors (e.g., social, school, neighborhood) that are protective for depression may also be protective for physical health, but this is an ongoing area of research. The goals of the current dissertation were to gain a better understanding of what depressive symptom presentations in adolescents are most concerning for adulthood …

Neuroanatomical And Morphometric Differences In Children Who Stutter, Mohammad A. Khan

Honors Scholar Theses

Childhood-Onset Fluency Disorder commonly known as stuttering is a neurodevelopmental speech disorder characterized by disruptions in speech fluency. While genetic and neurobiological factors are implicated, the structural brain differences underlying stuttering remain unclear. This study investigated neuroanatomical alterations in children who stutter (CWS) compared to typically fluent children (TFC), focusing on gray matter volume, cortical thickness, and surface area in speech-related regions; the Inferior Frontal Gyrus, Middle Temporal Gyrus, and Pre-motor Operculum. High-resolution MRI data from 100 children (48 CWS, 52 TFC) aged 3–12 years were analyzed using FreeSurfer.

The research emphasized the importance of collective parent-child dance therapy sessions, that especially focused on attunement and connection that built its way up from sensory-motor, social-communicative, and relational play and engagement.

A total of six parent-child dyads participated in the study that lasted over eight DMT sessions. Parents …

Who Cares For The Caregivers? How Dance And Movement Can Benefit Caregiving Parents Of Children With Intellectual/Developmental Disabilities: A Literature Review, Haley E. Gilbert

Expressive Therapies Theses

Caregiver parents of people with intellectual/developmental disabilities (IDD) are not able to care for themselves as often as they should be able to for their own mental and physical wellness due to their caregiving responsibilities that often carry into adulthood. These can lead to anxiety, depression, grief, and dysregulation for the parent. Dance and movement practices have been found to relieve the symptoms of these experiences while helping the child with IDD and the parent connect more, building stronger relationships. This thesis will include a comprehensive literature review of body-based theories such as the Polyvagal Theory (Polyvagal Institute, 2025), Bowlby’s …

Heredity, Chris Burley, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Heredity is the sum of biological processes that result in the transmission of genetic traits from parents to their offspring, making each individual unique. Through the transmission of genetic traits, heredity is responsible for each individual’s genotype, as well as his or her phenotype. The genes that are passed down from generation to generation have a considerable influence on psychological characteristics including intelligence, personality, mental health, and patterns of behavior. However, when considering psychological characteristics passed down through heredity, it is vital that environmental aspects are also considered.

Metabolic Theories Of Aging, Chris Burley, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Metabolic theories of aging postulate that aging is due to energy expenditure, which ultimately results in the breakdown and eventual death of cells. Historically, within the realm of metabolic theories of aging, there have been three models: The Rate-of-Living theory, The Oxidative Damage/Free Radical theory, and the Metabolic Stability theory. All three theories maintain that aging is directly related to metabolic rate, but the theories differ in how they arrive at that conclusion.

Neural Correlates Of Attentional Biases In Dietary Choice: Role Of Childhood Socioeconomic Status, Justine Jamie N. Gotico

CMC Senior Theses

Childhood poverty has been shown to increase adult risk for obesity above and beyond its direct effects on adult socioeconomic status (SES). One proposed mechanism of these effects is by shifting behavioral patterns of dietary consumption and choice, for example by increasing rapid attention to high-calorie unhealthy foods. Yet, whether such neural mechanisms can explain observed differences in dietary behavior based on childhood SES remains an open question. Here we used event-related potentials (ERPs) to examine early attentional correlates of low childhood SES during a dietary choice task, based on research suggesting that early attentional biases toward high-calorie foods emerge …
