摘要
Although a few developmental fMRI studies have shed some light on the neurological development of either object or spatial processing we still know very little about the development of the 'what' and 'where' processing systems. The present study is the first to address this issue by comparing, concurrently and within the same behavioral paradigm, patterns of functional activation for face processing and location processing in 12 children (10-12 years old) and 16 adults. For both tasks this study found a developmental shift from a more distributed pattern of activation in children to a more focused pattern of activation in adults. Furthermore, the type of developmental redistribution of activation in children varied depending on the task. The present findings have important implications for theories of visuospatial development. They suggest that the neural systems involved in face and location processing may undergo development and fine-tuning well into late childhood.
