Examining The Shift In Occupational Identity After A Brain Injury, Mikelle Bryson-Campbell

Electronic Thesis and Dissertation Repository

Occupational identity is defined by Kielhofner (2002) as a sense of who we are as an occupational being, based on our past, current, and future occupational roles. When a life disruption occurs such as a brain injury (BI) and the disruption impacts the ability to conduct an occupation deemed meaningful an important process of transition occurs (Muenchberger, Kendall, & Neal, 2008). In turn occupational identity may shift to reflect the current health and economic status of the individual and what occupations are judged as meaningful.

The current study examined the shift in occupational identity in BI survivors in a two …

Cortical Representation Underlying The Semantic Processing Of Numerical Symbols: Evidence From Adult And Developmental Studies, Stephan Erich Vogel

Electronic Thesis and Dissertation Repository

Humans possess the remarkable ability to process numerical information using numerical symbols such as Arabic digits. A growing body of neuroimaging work has provided new insights into the neural correlates associated with symbolic numerical magnitude processing. However, little is known about the cortical specialization underlying the representation of symbolic numerical magnitude in adults and children. To constrain our current knowledge, I conducted a series of functional Magnetic Resonance Imaging (fMRI) studies that aimed to better understand the functional specialization of symbolic numerical magnitudes representation in the human brain.

Using a number line estimation task, the first study contrasted the brain …

Socialization Of Depressive Symptoms In Pre- And Early Adolescent Peer Cliques, Suzanne L. Seah

Electronic Thesis and Dissertation Repository

This study examined socialization of depressive symptoms in pre- and early adolescent peer cliques, and clique characteristics (clique gender and friendship density) that may moderate the contribution of clique depression to the prediction of youths’ depressive symptoms over time. Social cognitive mapping identified 162 peer cliques involving 999 youths from Grades 4 through 8 (M age = 11.84; SD = 1.52) in Southwestern Ontario. As expected, multi-level modeling revealed that clique depressive symptoms in fall contributed significantly to the prediction of youths’ depressive symptoms in spring. Null findings regarding clique friendship density and gender as moderators of clique depression …

An Investigation Of The Association Between Arithmetic Achievement And Symbolic And Nonsymbolic Magnitude Processing In 5-9 Year-Old Children: Evidence From A Paper-And-Pencil Test, Nadia Nosworthy

Electronic Thesis and Dissertation Repository

Recently, there has been a growing emphasis on basic number processing competencies (such as the ability to judge which of two numbers is larger) and their role in predicting individual differences in school-relevant math achievement. Children’s ability to compare both symbolic (e.g. Arabic numerals) and nonsymbolic (e.g. dot arrays) magnitudes has been found to correlate with their math achievement. The available evidence, however, has focused on computerized paradigms, which may not always be suitable for universal, quick application in the classroom. Furthermore, it is currently unclear whether both symbolic and nonsymbolic magnitude comparison are related to children’s performance on tests …

Children's Understanding And Experience Of Anger Within Their Peer Groups, Nicole J. Hamel

Electronic Thesis and Dissertation Repository

The purpose of this study was to describe how children understand, experience and express their anger with others in their peer group, from their perspectives. Semi-structured focus groups were conducted with third grade students in an elementary school. Children were asked three questions: 1) What did you learn about dealing with anger this week? 2) What are some good/positive things that happened between you and your classmates this week? 3) What are some not so good or negative things that happened between you and your classmates this week? Six themes emerged from analysis of the transcripts of the semi-structured focus …

Gender And Grade Differences In How High School Students Experience And Perceive Cyberbullying, Jeremy D. Doucette

Electronic Thesis and Dissertation Repository

Gender and grade differences in how high school students experience and perceive cyberbullying was examined through a survey and focus groups with youth in southwestern Ontario, Canada. Survey findings revealed that boys reported cyberbullying more often than girls on most items while girls reported experiencing cyberbullying more often than boys on most items. Grade alone did not account for significant differences, but interactions with gender were sometimes found. The focus groups revealed that most students believe that girls cyberbully more than boys, but that boys are more likely than girls to view cyberbullying as a form of joking, and to …
