How Technology Interacts With Emerging Adulthood Psychosocial Developmental Tasks: An Examination Of Online Self-Presentation And Cell Phone Usage, Samantha Lynn Gray
How Technology Interacts With Emerging Adulthood Psychosocial Developmental Tasks: An Examination Of Online Self-Presentation And Cell Phone Usage, Samantha Lynn Gray
Doctoral Dissertations
This dissertation outlines three distinct, yet interrelated, projects aimed at understanding the role of technology in relation to emerging adulthood developmental tasks: individuation & identity development. The first paper provides a context for understanding the developmental tasks of emerging adulthood, and the role that technology may serve in relation to those developmental tasks. This brief review of the literature on emerging adulthood developmental tasks provides a solid theoretical background and history for the theoretical premises proposed for the respective studies included in this dissertation. The second project is an empirical investigation that seeks to understand how the task of identity …
The Impact Of Television Program Diet On Children's Achievement, Heather J. Lavigne
The Impact Of Television Program Diet On Children's Achievement, Heather J. Lavigne
Doctoral Dissertations
In this study, three waves of data from the Panel Study of Income Dynamics’s Child Development Supplement were used to examine patterns of children’s early TV exposure and its influence on middle childhood and adolescence. Analyses examined the pathways of influence depending on whether a dosage (hours of exposure) or diet (proportion of content to total TV time) variable was used. Results revealed that, in a dosage model, violent hours of early TV exposure were associated with decreases in independent reading and increases in externalizing behavior problems, but these did not predict later achievement. Early educational TV amount of exposure …
The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel
The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel
Doctoral Dissertations
Nocturnal sleep has been shown to benefit memory in adults and children. During the preschool age range (~3-5 years), the distribution of sleep across the 24-hour period changes dramatically. Children transition from biphasic sleep patterns (a nap in addition to overnight sleep) to a monophasic sleep pattern (only overnight sleep). In addition, early childhood is a time of neuronal plasticity and pronounced acquisition of new information. This dissertation sought to examine the relationship between daytime napping and memory consolidation in preschool-aged children during this transitional time. Children were taught either a declarative or an emotional task in the morning, and …
Emotion In Adoption Narratives: Links To Close Relationships In Emerging Adulthood, Holly A. Grant-Marsney
Emotion In Adoption Narratives: Links To Close Relationships In Emerging Adulthood, Holly A. Grant-Marsney
Doctoral Dissertations
An adopted person develops a narrative or story to help make sense of his or her adoption. This narrative provides a window into how the adoptee understands the role of adoption in his or her life and articulates feelings and thoughts about it. Adolescent and emerging adult adoptees’ data from the Minnesota-Texas Adoption Research Project (MTARP) were examined. MTARP longitudinally followed 190 adoptive kinship networks, with varying levels of openness in the adoption, from childhood to emerging adulthood. The current study sought to understand how emotion (affective valence and specific emotions), as identified in the adoption narratives during adolescence and …
Effects Of Stimulus Symmetry On Hierarchical Processing In Six-Month-Old Short- And Long-Looking Infants, Margaret Weinel Guy
Effects Of Stimulus Symmetry On Hierarchical Processing In Six-Month-Old Short- And Long-Looking Infants, Margaret Weinel Guy
Doctoral Dissertations
The current study investigated the effects of stimulus symmetry on the processing of global and local stimulus properties by 6-month-old short- and long-looking infants through the use of event-related potentials (ERPs). When compared with asymmetry, symmetry has been associated with more efficient stimulus processing and more accurate memory for stimulus configuration (Attneave, 1955; Perkins, 1932). Previous research has shown that individual differences in infant visual attention are related to hierarchical stimulus processing, such that short lookers show a precedence effect for global processing, while long lookers demonstrate a local processing precedence (Guy, Reynolds, & Zhang, 2013). Based on the Information …
