Associations Between Cumulative Risk, Childhood Sleep Duration, And Body Mass Index Across Childhood, Tiffany Phu, Jenalee R. Doom

Psychology: Faculty Scholarship

Background: Although associations between cumulative risk, sleep, and overweight/obesity have been demonstrated, few studies have examined relationships between these constructs longitudinally across childhood. This study investigated how cumulative risk and sleep duration are related to current and later child overweight/obesity in families across the United States sampled for high sociodemographic risk.

Methods: We conducted secondary analyses on 3690 families with recorded child height and weight within the Fragile Families and Child Well-Being Study. A cumulative risk composite (using nine variables indicating household/ environmental, family, and sociodemographic risk) was calculated for each participant from ages 3-9 years. Path analyses …

Integration And Segmentation Conflict During Ensemble Coding Of Aspect Ratio, Elric Matthew Elias

Electronic Theses and Dissertations

The visual system often integrates information that "goes together". Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall"). Segmentation allows the visual system to make quick categorical distinctions. Much of the time, integration …

Individual Adjustment As A Predictor Of Improvements In Romantic Relationship Quality From Adolescence To Adulthood, Jamie Novak Shoop

Electronic Theses and Dissertations

Previous work suggests that individuals who experience a poor quality romantic relationship during adolescence are at heightened risk of experiencing poor quality romantic relationships in adulthood. However, this literature has not yet identified factors that may predict which individuals will go on to experience improved romantic relationship quality in adulthood, despite having experienced a poor quality romantic relationship during adolescence. The goal of the current study was to examine whether adolescents' psychosocial adjustment (internalizing and externalizing symptoms, substance use, and self-esteem) predicted improvements in the quality of their subsequent romantic relationships. Data were drawn from a community sample of 200 …
