Abstract
Aphasic phonological errors have received considerable attention in the literature. Linguistic analysis of phonological production errors has been largely based on the distinctive feature framework. Phonological process analysis has been demontrated to be an effective approach in child phonology. Process analysis focuses on the strategies which result in phonological error, rather than on the error itself. Few studies have attempted to apply process analysis to the phonological errors of adult aphasics. This paper applies process analysis to the phonemic paraphasias of posterior lesion aphasics from six published studies. Clinical and research implications are presented.
