By using both behavioral measurements and functional MRI techniques, current project designed to explore behavioral and neural changes induced by learning of an artificial language. The main purposes of this project are to examine the cognitive function of the left superior parietal lobule (SPL) in word reading and learning. According to current results, we found that SPL showed specific activation in terms of visual feature, cognitive processes and modality. Firstly, when people learned non-alphabetic language, it showed that SPL is involved in semantic learning and transfer rather than in phonological learning and transfer. Secondly, SPL is engaged in visual word processing but not in auditory word processing. Third, SPL is found to be an important part of neural network for word reading, and these findings may be written-system-specific. In summary, current project helps us to understand the role of superior parietal lobule in word reading and learning, and to expand our knowledge about neural network of reading.
