Abstract

Two simulations were conducted using a replication of PMSP96 (Plaut, McClelland, Seidenberg, & Patterson, 1996, Simulation 4). The first simulation demonstrated that this implementation of PMSP96, was able to reproduce the standard effects of reading, and that when damaged by removal of the semantic input to phonology it produced the kind of frequency/consistency interactions and regularisation errors typical of surface dyslexia. The second simulation explored the effect of phonological damage followed by a period of recovery. This produced large lexicality effects characteristic of phonological dyslexia. This is the first time that symptoms of both of these reading disorders have been demonstrated by the same implementation of the triangle reading model.
