We describe a connectionist model designed to reflect some of the anatomy of the visual pathways, notably the precise division of the human fovea and its subsequent contralateral projection to the cortex. The model was trained on a realistically large-scale problem, mapping between Chinese orthography and phonology. This split-fovea model replicated the interaction between character regularity and frequency that has been found in Chinese phonetic compound naming tasks. It also provided cross-language support for the hemispheric desynchronization account of dyslexia. Finally, the model predicted different regularity effects between characters with different phonetic radical positions.
