Sonorant sustainment: a single case study of a rare phonemic deficit in aphasia. Bastiaanse, R.; Gilbers, D.; and van der Linde, K. Clinical Linguistics & Phonetics, 8(1):27-43.
abstract   bibtex   
This single case study treats a rare, if not unique, symptom: sonorant sustainment. The patient involved suffers from a mild anomia, but apart from that he sustains sonorants in very strictly defined positions in the utterance. Detailed analysis of his spontaneous speech reveals that sustainment of sonorants is determined by certain phonological domains, whereas other phonological domains are of no influence at all. The authors have tried to establish the exact locus of impairment, which is assumed to be postlexical and prephonetic. Hence, sonorant sustainment may be considered a phonemic paraphasia. A possible explanation for sustainment of the sonorants is proposed within the framework of phonological domains.
