Impaired Oral Reading in Surface Dyslexia: Detailed Comparison of a Patient and a Connectionist Model

Mapping between orthography and phonology in the absence of semantics is investigated in a surface dyslexic patient, MP, and in a connectionist model. Both were tested on about 2500 monosyllabic words from the Seidenberg and McClelland corpus. We examined detailed effects of word frequency and spelling-sound consistency on naming accuracy and latency. We also performed an error analysis. While the general agreement in performance is encouraging, specific discrepancies suggest possible improvements of the model.
