We investigated the contribution of temperament and external environment to severity children who stutter. Sixty-nine stutter, ages 2;4 5;9 (years; months), with a mean age 3;7, were assessed for temperament, home environment, significant life events. Temperament was using Children's Behavior Questionnaire. Home events Confusion, Hubbub Order Scale (CHAOS) scale Life Events Checklist. Results indicated mother (parent)-reported stuttering clinician-reported be correlated child scores in...
This study aimed to identify cases of developmental stuttering and associated comorbidities in de-identified electronic health records (EHRs) at Vanderbilt University Medical Center, and, turn, build test a prediction model. A multi-step process including keyword search medical notes, text-mining algorithm, manual review was employed the EHR. Confirmed were compared matched controls phenotype code (phecode) enrichment analysis reveal conditions with (i.e., comorbidities). These phenotypes...
Background In 2014, Kraft et al. assessed the temperament, home environment, and significant life events of 69 North American children who stutter to examine combined compounded effects these individualized factors on mediating overt stuttering severity. The temperament domain effortful control was singularly found be significantly predictive Purpose Because clinical significance initial study's findings, a replication study with different, larger cohort warranted validate reported outcomes....
Delayed auditory feedback (DAF) is known to induce stuttering-like disfluencies (SLDs) and cause speech rate reductions in normally fluent adults, but the reason for disruptions not fully known, individual variation has been well characterized. Studying susceptibility DAF may identify factors that predispose an be more or less dependent on feedback.Participants were 62 adults. Each participant performed a spontaneous task 250-ms amplified nondelayed (NAF) conditions. SLDs, other (ODs),...
Developmental stuttering is a speech disorder characterized by disruption in the forward movement of speech. This includes part-word and single-syllable repetitions, prolongations, involuntary tension that blocks syllables words, has life-time prevalence 6–12%. Within Vanderbilt's electronic health record (EHR)-linked biorepository (BioVU), only 142 individuals out 92,762 participants (0.15%) are identified with diagnostic ICD9/10 codes, suggesting large portion people who stutter do not...
Despite a lifetime prevalence of at least 5%, developmental stuttering, characterized by prolongations, blocks, and repetitions speech sounds, remains largely idiopathic disorder. Family, twin, segregation studies overwhelmingly support strong genetic influence on stuttering risk; however, its complex mode inheritance combined with thus-far underpowered contribute to the challenge identifying reproducing genes implicated in susceptibility. We conducted trans-ancestry genome-wide association...
<title>Abstract</title> Developmental stuttering is a common speech disorder (studies estimate at least 5% lifetime prevalence) characterized by prolongations, blocks, and repetitions of sounds. In approximately 75–80% cases in early childhood, will resolve within few years (referred to as ‘recovery’); the remaining often experience into school-age adulthood ‘persistence’). adults, prevalence substantially higher men compared women, ratio 4:1 or greater (compared between 1:1 2:1 young...
Purpose The purpose of this study was to test whether adults who stutter (AWS) display a different range sensitivity delayed auditory feedback (DAF). Two experiments were conducted assess the fluency AWS under long-latency DAF and effect short-latency on speech kinematic variability in AWS. Method In Experiment 1, 15 performed conversational speaking task nonaltered 250-ms DAF. rates stuttering-like disfluencies, other errors articulation rate compared. 2, 13 do not (AWNS) read three...
A role for auditory feedback in maintaining fluency appears less specific than pitch control, as one example, but delayed (DAF) clearly provides a potent manipulation of fluency. As most speakers are susceptible to DAF, we predicted DAF is particularly suited identifying individual differences auditory-motor integration. We conducted series studies probe susceptibility DAF-induced disfluency 60 normally fluent during conversation and oral reading. further contrasted effects on with dual-task...
