Infant And Child Multisensory Attention Skills: Methods, Measures, And Language Outcomes, Elizabeth V. Edgar
Infant And Child Multisensory Attention Skills: Methods, Measures, And Language Outcomes, Elizabeth V. Edgar
FIU Electronic Theses and Dissertations
Intersensory processing (e.g., matching sights and sounds based on audiovisual synchrony) is thought to be a foundation for more complex developmental outcomes including language. However, the body of research on intersensory processing is characterized by different measures, paradigms, and research questions, making comparisons across studies difficult. Therefore, Manuscript 1 provides a systematic review and synthesis of research on intersensory processing, integrating findings across multiple methods, along with recommendations for future research. This includes a call for a shift in the focus of intersensory processing research from that of assessing average performance of groups of infants, to one assessing individual differences …
The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea
The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea
FIU Electronic Theses and Dissertations
In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …
The Influence Of Maternally Regulated Prenatal Sensory Experience On Postnatal Motor Coordination In Neonatal Bobwhite Quail, Starlie C. Belnap
The Influence Of Maternally Regulated Prenatal Sensory Experience On Postnatal Motor Coordination In Neonatal Bobwhite Quail, Starlie C. Belnap
FIU Electronic Theses and Dissertations
Comparative animal studies aid in understanding how prenatal sensory experiences regulated by maternal activity facilitate or interfere with growth and phenotype development. However, there is a paucity of information on how prenatal sensory experience influence postnatal motor performance. In this series of studies, we used an avian model, the bobwhite quail, to evaluate the effects of prenatal temperature (study 1), prenatal movement (study 2), prenatal light duration (study 3), and prenatal light presentation pattern (study 4) on hatchability, growth and postnatal motor performance in 24hr quail neonates. In study 1, quail embryos were exposed to naturally occurring cool (36.9°C) or …
Effects Of Altered Prenatal Sensory Stimulation On Postnatal Contingency Learning In Bobwhite Quail Neonates (Colinus Virginianus), Namitha Raju
FIU Electronic Theses and Dissertations
Preterm infants are exposed to high levels of modified early sensory experience in the Neonatal Intensive Care Unit (NICU). Reports that preterm infants show deficits in contingency detection and learning when compared to full-term infants (Gekoski, Fagen, & Pearlman, 1984; Haley, Weinberg, & Grunau, 2006) suggest that their exposure to atypical amounts or types of sensory stimulation might contribute to deficits in these critical skills. Experimental modifications of sensory experience are severely limited with human fetuses and preterm infants, and previous studies with precocial bird embryos that develop in ovo have proven useful to assess the effects of modified perinatal …
