In addition, patients exhibit a number other symptoms, including visual and morphological effects in their errors, part-of-speech effect, advantage for concrete over abstract words. poses distinct challenge cognitive neuropsychology because there little understanding why such variety symptoms should co-occur virtually all known patients. Hinton Shallice (1991) replicated co-occurrence lesioning recurrent connectionist network trained to map from orthography semantics. Although success simulations encouraging. what underlying principles are responsible them. this paper we evaluate and, where possible, improve on most important design decisions made Shallice, relating task, architecture, trai...
