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

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

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 …

The Role Of Representational Flexibility In Toddlers' Manual Search, Lauren Hartstein

Masters Theses

In the model room task, children watch as a miniature toy is hidden somewhere in a scale model of a room and are asked to find the larger version of the toy in the corresponding place in the actual room. Previous work has shown that children under age three often perform very poorly on this task. One prominent theory for their failure is that they lack the ability to understand the model as both a physical object and as a symbolic representation of the larger room. An alternative hypothesis is that they need to overcome weak, competing representations of where …

Through A Critical Sociocultural Lens: Parents’ Perspectives Of An Early Childhood Program In Guatemala, Yaëlle Stempfelet

Master's Capstone Projects

The present case study is on an Early Childhood program in Guatemala based on participant parents’ feedback. The Early Childhood program is non-formal, focuses on emergent literacy and nutrition, and takes place in a community-run library in a poor, semi-rural town in the mountainous regions of Quiche, Guatemala. The library was set up by a Non-Governmental Organization (NGO) that works in Guatemala as well as another neighboring country.

Using a critical sociocultural lens, this study assumes that the parents’ perceptions reflect the state of the program and that involving their feedback through this research will ultimately help to bolster the …

Predicting Social Behavior By Sound & Surface Appearance In Infancy, Ashley Lyons

Masters Theses 1911 - February 2014

Our naïve theory of social behavior assumes that the positive and negative actions of others are caused by some underlying social disposition. Furthermore, adults automatically infer such traits in advance based upon whatever observable, even superficial, properties are available (e.g., how someone looks or sounds). The goal of the current study is to explore the developmental origins of this bias. We tested whether 12-month-old infants automatically infer a character’s social disposition (i.e., whether they ‘help’ or ‘hinder’ another character’s goal) based upon the superficial properties they display. Infants were habituated to two characters that possessed surface properties that were rated …
