The loci of stuttering: grammar or prosody?

Much of the research dealing with linguistic dimensions in stuttering has emphasized the various aspects of grammar, particularly as these aspects contribute to the meaning of utterances. However, data from several sources indicate that meaning and grammatical features are not likely to be the important language variables related to stuttering, but that stuttering occurrence is linked more closely to the prosodic dimension. The published literature in this area reports work done with English-speaking subjects; comparable material from other languages would be of considerable value to our understanding of linguistic determinants in stuttering.
