Pure alexia

The SERIOL model offers a novel account of pure alexia. The usual interpretation is that the spared RH cannot process letters in parallel, thus serial letter-by-letter reading is performed instead. I suggest instead that letters normally undergo very rapid serial analysis, and the RH cannot provide this rapid serial processing. Because serial input is required by the spared lexical system, overt serial processing is performed instead. For a more detailed development of this idea, including a novel proposal for the nature of RH-specific visual processing and a more detailed specification of the dorsal route in the SERIOL model, see this article.
