A phonological analysis of the expressive and receptive articulatory difficulties of an aphasic with apraxia of speech: A case study

[摘要] The expressive and receptive phonological errors of an aphasic subject with mild apraxia of speech were analysed in terms of a distinctive feature framework. The results indicated that errors could be characterized linguistically and that such information could be of therapeutic significance. The relationship between articulation problems and ability to discriminate phonemes was investigated. Although no direct relationship was found, discrimination errors followed linguistic trends demonstrated in the articulation errors. The findings of this study suggest that the traditional idea of apraxia as a non-linguistic and purely motor disorder needs re-examination.
