How Do We Learn To Hope? The Development Of The Parent Report Of Child Hope, Lauren A. Sparks
How Do We Learn To Hope? The Development Of The Parent Report Of Child Hope, Lauren A. Sparks
Wayne State University Dissertations
Hope has been shown to be an important protective factor, with hypothesized origins in early childhood (Snyder, 2002). However, despite the established importance of hope, little research to date has examined its developmental origins. Specifically, a lack of appropriate instrumentation represents a significant barrier to detecting hope in children under the age of eight years old. The current study meets this need by examining the reliability and validity of a novel parent-report measure of hope in early childhood, titled the Parent Report of Child Hope (PRCH). The PRCH represents an initial step towards understanding individual differences in early childhood hope. …
Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang
Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang
Wayne State University Dissertations
The ability to remember past events is critical for everyday life and showed robust improvement over development from childhood to adulthood. With advances in noninvasive neuroimaging methods such as functional MRI in recent years, research efforts have been focused on identifying neural correlates underpinning developmental gains in memory performance. In my dissertation work, using a widely-validated subsequent memory paradigm, I aim to characterize functional MRI correlates of memory development. Specifically, I focused my investigation on identifying age differences in the functional patterns of two brain regions critical for memory, the prefrontal cortex and the hippocampus. Focusing on the prefrontal cortex …
Sexual Orientation Development, Acceptance, And Risk Behavior In Young Adult Gay Men, Erin Paige Smith
Sexual Orientation Development, Acceptance, And Risk Behavior In Young Adult Gay Men, Erin Paige Smith
Wayne State University Dissertations
Research on sexual orientation development points to individual differences in developmental milestones (i.e., realization, identification, disclosure to friend, disclosure to parent, same-sex sexual behavior) that could be differentially related to adjustment. Additionally, differences in perceptions of acceptance from the self and important others, such as parents and friends, during adolescence and early adulthood may be related to both sexual orientation development and health risk behaviors (i.e., substance use, sexual risk). The goal of the current study was to advance our understanding of developmental processes among gay men by examining perceived acceptance of sexual orientation and its associations with individual differences …
Urban African American Youths' Academic Performance As Related To Fathers' Involvement During Development, Travis A. Goldwire
Urban African American Youths' Academic Performance As Related To Fathers' Involvement During Development, Travis A. Goldwire
Wayne State University Dissertations
Father involvement in the context of urban African American youth was examined using a subsample (n = 556) of a large cohort of participants followed longitudinally through development. Data was collected at regular intervals (e.g., Age 7, 14, 19 and young adult). Young adults (n = 93) were surveyed for retrospective accounts of their fathers’ involvement in their lives before age 18. In the young adult data collection phase (the main subject of this project), most participants reported varying levels and frequency of involvement from their fathers while growing up, including helping at school, providing social support, and encouraging academic …
Analyzing The Interactions Of Kdm5/Lid And Sin3 In Drosophila Melanogaster, Ambikai Gajan
Analyzing The Interactions Of Kdm5/Lid And Sin3 In Drosophila Melanogaster, Ambikai Gajan
Wayne State University Dissertations
SIN3, the scaffold protein of a histone modifying complex is conserved from yeast to mammals. Drosophila SIN3 associates with both a histone deactylase RPD3 and a histone demethylase dKDM5/LID. Immunopurification of dKDM5/LID verifies a previously observed interaction with SIN3 and RPD3. Furthermore, deficiency of dKDM5/LID phenocopies deficiency of SIN3 in many cellular and developmental processes. Knockdown of both Sin3A and lid hinder cell proliferation in Drosophila cultured cells and developing flies. Knockdown of these genes also results in a curved wing phenotype implicating a role in wing development. Analysis of underlying gene expression changes upon decreased expression of SIN3, dKDM5/LID …
Understanding The Role Of Nutritional Stress In The Adult And Developing Zebra Finch, Jessica Bayley Thompson
Understanding The Role Of Nutritional Stress In The Adult And Developing Zebra Finch, Jessica Bayley Thompson
Wayne State University Dissertations
Songbirds are particularly susceptible to stress during the sensitive period for song learning. Thus the developmental stress hypothesis (DSH) proposes that adult song reflects a male's early life environment during this period. Nutritional stress (NS) has been shown to cause deficits in song learning and adult song output that are salient to females. Female song birds consistently prefer control males over those raised under NS, yet the effects NS on females are still unclear. The hypothalamic-pituitary-adrenal axis (HPA) has been implicated in this process. However, evidence directly linking HPA functioning to the deficits due to NS have inconsistently shown elevations …
