This commentary on EC 232 373 and EC 232 374 suggests that a theory that depends on categorizing events as either stuttering or nonstuttering must fail. It evaluates the merit of the voluntary/involuntary distinction in loss of speech production control, defends research on the nature of stuttering, and proposes additional research and theory.…

The three-component model considers competencies at the utterance level, suprasegmental level, and discourse level. (Author/JDD)

A response is presented to commentaries (EC 232 375-377) on two papers (EC 232 373 and EC 232 374), focusing on research methodology on stuttering, the impact of improving intrajudge and interjudge agreement, the importance of studying stuttering as a private experience rather than an acoustical event, and speakers' experience of loss of control…

Research and clinical data regarding concomitant speech and language problems in children who stutter are reviewed, along with theoretical models explaining this interrelationship. A framework is presented for the differential evaluation of children who stutter, involving four areas of assessment: case history, fluency assessment, language skills…
