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 …
The Role Of Representational Flexibility In Toddlers' Manual Search, Lauren Hartstein
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 …
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
Masters Theses
Previous research with infants, children, and adults has shown that global, or configural, information is processed before local, or featural, information in high density visual hierarchical patterns (Freeseman, Colombo, & Coldren, 1993; Ghim & Eimas, 1988; Kimchi, 1988; Navon, 1981; Navon, 1977). The current study used event-related potential to determine if a well documented bias toward global processing in infancy can be disrupted when the number and density of local elements is reduced through increasing the distance between elements. Infant responses were compared between high and low density conditions to global and local novel patterns and to familiar patterns. A …
Effects Of Instruction And Parent-Child Conversation On Children's Stem Learning And Transfer, Maria Marcus
Effects Of Instruction And Parent-Child Conversation On Children's Stem Learning And Transfer, Maria Marcus
Master's Theses
This study examined the effects of direct instruction and parent-child conversation on children's STEM learning, transfer abilities, and remembering. A total of forty mothers and their 5- to 6-year-old children (M = 5.87) participated in this study. Mother-child dyads were randomly assigned to one of two conditions that differed in the amount of engineering information they received prior to engaging in a building activity in a museum exhibit. The provision of engineering information fostered dyads building activities and their long-term recall of the museum visit. Implications for museum research and practice are discussed.
