How stuttering develops: The multifactorial dynamic pathways theory
A Smith, C Weber - Journal of Speech, Language, and Hearing Research, 2017 - ASHA
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 …

Childhood stuttering: Where are we and where are we going?
A Smith, C Weber - Seminars in Speech and Language, 2016 - thieme-connect.com
Remarkable progress has been made over the past two decades in expanding our
understanding of the behavioral, peripheral physiologic, and central neurophysiologic bases
of stuttering in early childhood. It is clear that stuttering is a neurodevelopmental disorder …

Evidence that a motor timing deficit is a factor in the development of stuttering
L Olander, A Smith, HN Zelaznik - 2010 - ASHA
Purpose To determine whether young children who stutter have a basic motor timing and/or
a coordination deficit. Method Between-hands coordination and variability of rhythmic motor
timing were assessed in 17 children who stutter (4–6 years of age) and 13 age-matched …

Increasing phonological complexity reveals heightened instability in inter-articulatory coordination in adults who stutter
The potential role of phonological complexity in destabilizing the speech motor systems of
adults who stutter was explored by assessing the performance of 17 adults who stutter and
17 matched control participants on a nonword repetition task. The nonwords varied in length …

Language and motor abilities of preschool children who stutter: Evidence from behavioral and kinematic indices of nonword repetition performance
Stuttering is a disorder of speech production that typically arises in the preschool years, and
many accounts of its onset and development implicate language and motor processes as
critical underlying factors. There have, however, been very few studies of speech motor …

[HTML][HTML] Speech motor planning and execution deficits in early childhood stuttering
Five to eight percent of preschool children develop stuttering, a speech disorder with clearly
observable, hallmark symptoms: sound repetitions, prolongations, and blocks. While the
speech motor processes underlying stuttering have been widely documented in adults, few …

Atypical neural functions underlying phonological processing and silent rehearsal in children who stutter
Phonological processing was examined in school‐age children who stutter (CWS) by
assessing their performance and recording event‐related brain potentials (ERPs) in a visual
rhyming task. CWS had lower accuracy on rhyming judgments, but the cognitive processes …

A lag in speech motor coordination during sentence production is associated with stuttering persistence in young children
Purpose The purpose of this study was to determine if indices of speech motor coordination
during the production of sentences varying in sentence length and syntactic complexity were
associated with stuttering persistence versus recovery in 5-to 7-year-old children. Methods …

Influences of sentence length and syntactic complexity on the speech motor control of children who stutter
MK MacPherson, A Smith - 2013 - ASHA
Purpose To investigate the potential effects of increased sentence length and syntactic
complexity on the speech motor control of children who stutter (CWS). Method Participants
repeated sentences of varied length and syntactic complexity. Kinematic measures of …

[HTML][HTML] What are predictors for persistence in childhood stuttering?
Over the past 10 years, we (the Purdue Stuttering Project) have implemented longitudinal
studies to examine factors related to persistence and recovery in early childhood stuttering.
Stuttering develops essentially as an impairment in speech sensorimotor processes that is …
