  abstract	= {Two hypotheses have been advanced concerning the basis of
		  acquired phonological dyslexia. According to the dual-route
		  model, the pattern derives from impaired grapheme-phoneme
		  conversion. According to the phonological impairment
		  hypothesis, it derived from impaired representation and use
		  of phonology. Effects of graphemic complexity and visual
		  similarity observed in studies by Howard and Best (1996),
		  orthographic effects on phoneme counting (Berndt et al.
		  1996) and data from patient LB (Derouesne and Beauvois
		  1985) have been taken as evidence for an orthographic
		  impairment in phonological dyslexia and therefore against
		  the impaired phonology hypothesis (Coltheart 1996). We
		  present a computational simulation, results of two
		  behavioral studies and a critical analysis of the MJ and LB
		  data which suggest that the "orthographic" deficits in such
		  patients arise from phonological impairments that interact
		  with orthographic properties of stimuli.}
