Abstract:
Objective:To explore the language deficits in a single case of posterior aphasic to test the dual-system model of language processing and provide neurolinguistic basis for clinical language therapy.Method:A circumscribed posterior aphasic was selected,whose language data were collected through spontaneous talk,WAB test,and other language production tasks including picture-naming and sentence repetition.The language data were analyzed with the emphasis on syntax-lexicon dissociation and noun-verb dissociation.Result:For the posterior aphasic,lexicon was severely impaired while syntax was preserved relatively well;in comparison to lexical production,lexical comprehension was preserved better;noun-verb dissociation,especially NSD,was discovered.Conclusion:The syntax-lexicon dissociation and the relevant noun-verb dissociation can serve as powerful evidence for the dual-system model of language processing,and throw light on language therapy for posterior aphasics.
