This dissertation aims to specify patterns of visual-spatial processing following lateralized pre- or perinatal brain injury and during normal development. Previous work with young children and adults has shown that damage to the left hemisphere (LHD) leads to deficits in visual segmentation and damage to the right hemisphere (RHD) leads to deficits in visual integration. Study 1 assessed whether this characteristic pattern of deficit persists in a school-aged population of children who sustained pre- or perinatal LHD and RHD. Two response-time tasks tested the spatial processing abilities known to be affected by lateralized brain injury. In the selective attention task, subjects responded to the direction of a single item while ignoring a distractor. In the integration task, subjects judged the similarity of two items. Contrary to an anticipated double dissociation, children with lateralized brain injury demonstrated impairments on both the selective attention and integration tasks. An analysis of each groups' performance suggested that the underlying nature of their deficits on the two tasks was quite different. Consistent with previous reports of lateralized spatial deficits in young children and adults, the impaired performance in school-aged children with LHD was attributed to pervasive deficits in visual segmentation, and the impaired performance in school-aged children with RHD was attributed to pervasive deficits in visual integration. Study 2 examined the effects of processing demands on attention in a cross-sectional sample of neurologically normal subjects. This study also represented an attempt to simulate a LHD and RHD profile of spatial performance in normal subjects. Subjects participated in a variation of the selective attention and integration tasks, where the orientation of the presented stimuli was manipulated in order to increase or decrease the processing demands of the task. The results of the complexity manipulation suggested that under specified conditions, the attentional abilities of normal subjects could be altered. However, Study 2 failed to simulate a brain injured profile of performance. Taken together, these studies contribute to the further understanding of visual spatial attention in neurologically atypical and typical populations.

The genetic, molecular, and cellular mechanisms of neural development are essential for understanding evolution and disorders of neural systems. Recent advances in genetic, molecular, and cell biological methods have generated a massive increase in new information, but there is a paucity of comprehensive and up-to-date syntheses, references, and historical perspectives on this important subject. The Comprehensive Developmental Neuroscience series is designed to fill this gap, offering the most thorough coverage of this field on the market today and addressing all aspects of how the nervous system and its components develop. Particular attention is paid to the effects of abnormal development and on new psychiatric/neurological treatments being developed based on our increased understanding of developmental mechanisms. Each volume in the series consists of review style articles that average 15-20pp and feature numerous illustrations and full references. Volume 3 offers 40 high level articles devoted mainly to anatomical and functional development of neural circuits and neural systems, as well as those that address neurodevelopmental disorders in humans and experimental organisms. - Series offers 144 articles for 2904 full color pages addressing ways in which the nervous system and its components develop - Features leading experts in various subfields as Section Editors and article Authors - All articles peer reviewed by Section Editors to ensure accuracy, thoroughness, and scholarship - Volume 3 sections include coverage of: mechanisms that control the assembly of neural circuits in specific regions of the nervous system, multiple aspects of cognitive development, and disorders of the nervous system arising through defects in neural development
