The formation of the past tense of verbs in English has been the focus of the debate concerning connectionist vs. symbolic accounts of language. Brain-injured patients differ with respect to whether they are more impaired in generating irregular past tenses (TAKE-TOOK) or past tenses for nonce verbs (WUG-WUGGED). Such dissociations have been taken as evidence for distinct "rule" and "associative" memory systems in morphology and against the connectionist approach in which a single system is used for all forms. We describe a simulation model in which these impairments arise from damage to phonological or semantic information, which have different effects on generalization and irregular forms, respectively. The results provide an account of the bases of impairments in verb morphology and show that these impairments can be explained within connectionist models that do not use rules or a separate mechanism for exceptions.
Management protocols for minor head injury should include strategies for early detection of intracranial haematomas. This study focuses on the management of minor head injury in 63 Norwegian hospitals. We report considerable inter-hospital variation. In most (81%) hospitals, minor head injury patients were treated by general surgeons. Emergency room evaluation included routine radiological evaluation, usually skull radiography, in 18 (29%) hospitals, and assessment according to the Glasgow Coma Scale (GCS) in 27 (43%). GCS was used during in-hospital observation in 32 (51%) hospitals. 33 (52%) discharged selected minor head injury patients without in-hospital observation. We conclude that the quality of care for minor head injury patients in Norwegian hospitals can be improved through extended use of routine early CT and consistent evaluation according to GCS.
