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 Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes
The Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes
Masters Theses & Specialist Projects
The ability of 16 younger adults to visually perceive distances in depth was evaluated within three environmental contexts (indoors in the dark, indoors in the light, and outdoors). The observers' task was to bisect an 8m distance interval in all contexts using both monocular and binocular vision. In the outdoor environment (a natural grassy field), the observers' judgments indicated perceptual compression of farther distances similar to that obtained in many previous studies. In the indoor lighted environment (a 10.2 x 9.6m laboratory room), the observers' judgments were consistent with perceptual expansion of farther distances. Finally, there was a beneficial effect …
