To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

In a simulation, the lesioning of a connectionist model that maps orthographic inputs onto semantic features produces several counterintuitive behaviors that are also shown by acquired-dyslexic patients. The similarity strengthens the suggestion that the connectionist approach captures a key aspect of human cognitive processing. (SLD)
