“…Starkweather (1995) proposed the "proximal" cause of stuttering is the overactivation of the muscles involved in speech. Packman, Code, and Onslow (2007) more recently pinpointed the proximal cause of stuttering as a difficulty in initiating syllables as a result of disrupted function in the supplementary motor area's role in initiation and sequencing of syllablebased speech motor programs. In the EXPLAN theory of Howell (2004), linguistic planning is slowed so that motor execution processes repeat or stop on the current element, resulting in disfluencies.…”

Purpose: We advanced a multifactorial, dynamic account of the complex, nonlinear interactions of motor, linguistic, and emotional factors contributing to the development of stuttering. Our purpose here is to update our account as the multifactorial dynamic pathways theory. Method: We review evidence related to how stuttering develops, including genetic/epigenetic factors; motor, linguistic, and emotional features; and advances in neuroimaging studies. We update evidence for our earlier claim: Although stuttering ultimately reflects impairment in speech sensorimotor processes, its course over the life span is strongly conditioned by linguistic and emotional factors.

“…Within the frontal motor cortex, the supplementary motor area (SMA, including both the SMA proper and anterior supplementary motor area -preSMA) may play a special role. Many studies have shown a close relation between the SMA and stuttering (see Abe et al, 1993;Alm, 2004;Packman et al, 2007). Although previous studies on stuttering did not focus on the differences between the SMA proper and preSMA (e.g., Braun et al, 1997;Fox et al, 2000;Ingham et al, 2000), the preSMA, along with the basal ganglia, seems to have a closer relation with syllable representation and spatially and temporally serial coordination of motor apparatus than does the SMA proper (e.g., Alario et al, 2006;Bohland and Guenther, 2006;Crosson et al, 2001;Ferrandez et al, 2003;Hikosaka et al, 1996;Lewis et al, 2004).…”

“…It is thought that syllable motor gestures are retrieved from a mental syllabary [23] and sequenced for the production of the planned utterance. It has been suggested that failure to initiate syllables in a timely fashion is the problem in stuttering [24]. …”

Objective: We report on 12 children with end-word dysfluencies (EWDs). Our aim was to document this little-reported type of dysfluency and to develop a possible explanation for them and how they relate to developmental stuttering. Method: Audio recordings were made for 9 of the 12 children in the study. The EWDs were identified by consensus of two specialist speech pathologists and confirmed on acoustic displays. A segment of participant 1's speech was transcribed, including phonetic transcription of EWDs. Results: The EWDs typically consisted of repetitions of the nucleus and/or the coda. However, there were also some EWDs that consisted of fixed postures on the nucleus (when in final position) or coda. We also report on the infrequent occurrence of broken words. Ten of the 12 children also stuttered, with 9 of them coming from four families, each with a history of stuttering. Conclusion: This study indicates that EWDs may be more prevalent than previously thought, but they may go largely unnoticed due to their perceptually fleeting nature. The hypothesis was developed that EWDs be regarded as another type of developmental dysfluency, along with stuttering and cluttering. Ideas for further research are suggested. © 2014 S.
