The purpose of the present investigation was to examine the relation between utterance complexity and utterance position and the tendency to stutter on function words in preschool-age children who stutter (CWS). Two separate studies involving two different groups of participants (Study 1, n = 30; Study 2, n = 30) were conducted. Participants were…

Systematic evaluation of the task demands of changes in utterance length and complexity among stuttering (N=8) and nonstuttering (N=8) three- through six-year-olds revealed that fluency breakdown was significantly correlated with gradual increases in syntactic complexity for both stuttering and nonstuttering children, as was sentence replication…

This study examined language and fluency characteristics of single-utterance (SU) and multiple-utterance (MU)conversational turns produced by 15 preschoolers who stutter and 15 nonstuttering peers. Results suggest that MU turns are demanding for young children because they evoke relatively long and complex utterances and that clinicians should…

The Lidcombe Program is an operant treatment for early stuttering. Outcomes indicate that the program is effective; however, the underlying mechanisms leading to a successful reduction of stuttering remain unknown. The purpose of this study was to determine whether fluency achieved with the Lidcombe Program was accompanied by concomitant reduction…
