Purpose: Language abilities have long been thought to be weaker in adults who stutter (AWS) compared to adults who do not stutter (AWNS). However, it is unknown whether modality affects language performance by AWS in time pressure situations. This study aimed to examine lexical access and retrieval abilities of AWS in oral and typed modes. Method:…

Purpose: The aim of this study was to examine how nonword repetition (NWR) performance may be impacted by the presence of concomitant speech and language disorders in young children who stutter (CWS). Method: One hundred forty-one children (88 CWS and 53 children who do not stutter [CWNS]) participated. CWS were divided into groups based on the…

Purpose: Previous studies of neural processing of rhyme discrimination in 7- to 8-year-old children who stutter (CWS) distinguished children who had recovered, children who had persisted, and children who did not stutter (CWNS; Mohan & Weber, 2015). Here, we investigate neural processing mediating rhyme discrimination for early acquired real…

The present study aimed to identify the level of self-esteem among individuals with speech disorders; fluency, articulation, and voice disorders, in light of some variables. Researchers used Rosenberg's self-esteem scale on the study sample consisted of (97) individuals with speech disorders in hearing, speech clinics and special education centers…

Purpose: We review two recent neuroanatomical studies of children who stutter (CWS), one that examines white matter integrity and the other that focuses on cortical gray matter morphology. In both studies, we sought to examine differences between children whose stuttering persists ("persistent"), children who recovered from stuttering…

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: We compared children with persistent stuttering (CWS-Per) with children…

Background: In recent years, there has been increased identification of disfluencies in individuals with autism, but limited examination of disfluencies in the school-age range of this population. We currently lack information about whether the disfluencies of children with autism represent concomitant stuttering, normal disfluency, excessive…

This study was designed to characterize the brain system that monitors speech in people who stutter and matched controls. We measured two electrophysiological peaks associated with action-monitoring: the error-related negativity (ERN) and the error positivity (Pe). Both the ERN and Pe were reliably observed after errors in a rhyming task and a…

In this prospective study, data on incidence, stuttering characteristics, co-occurring speech disorders, and recovery of neurogenic stuttering in a large sample of stroke participants were assessed. Following stroke onset, 17 of 319 participants (5.3%; 95% CI, 3.2-8.3) met the criteria for neurogenic stuttering. Stuttering persisted in at least…

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 control processes in preschool children who stutter. Hearing novel nonwords and…

In this exploratory study, we investigated whether or not people who stutter (PWS) show motor practice and learning changes similar to those of people who do not stutter (PNS). To this end, five PWS and five PNS repeated a set of non-words at two different rates (normal and fast) across three test sessions (T1, T2 on the same day and T3 on a…

This paper argues against definitions of stuttering which imply that all within-word disfluencies are stuttering and no between-word disfluencies are stuttering. The paper calls for a definition of stuttering that is not contradicted by available empirical information or clinical experience and is logically consistent. (JDD)

Stutterers (N=201) and their nonstuttering same sex siblings were distributed identically in early, average, and late categories of language onset. Late talkers had significantly higher frequencies of articulation problems than did stutterers who were early or average talkers and their siblings. (Author/CL)

The times needed to initiate and terminate voicing in response to series of short segments of auditory signal were studied for 20 stuttering and 20 nonstuttering children (ages for both groups 5 to 12). The effects of random reward and nonreward on the phonatory response times also were studied. (Author/PHR)

This study of 21 children (ages 4-6) found that children with stuttering and disordered phonology produced more sound prolongations and fewer iterations per whole-word repetition than did children who stuttered but had normal phonology. No differences were noted between children with stuttering and disordered phonology and children with disordered…
