Extant models of stuttering do not account for the emergence of stuttering at the onset of productive language use; the greater incidence of stuttering during spontaneous speech, on complex sentences, and at sentence-initial positions; the greater incidence of stuttering in bilinguals' 2nd language; the apparent deficiency of stutterers in expressive and receptive language skills; the prevalenc...

OBJECTIVES To document the natural history of stuttering by age 4 years, including (1) cumulative incidence of onset, (2) 12-month recovery status, (3) predictors of stuttering onset and recovery, and (4) potential comorbidities. The study cohort was a prospective community-ascertained cohort (the Early Language in Victoria Study) from Melbourne, Australia, of 4-year-old children (n = 1619; rec...

This investigation concerns the persistence of stuttering and recovery from it among highrisk children. At the end of the second year of a 6-year prospective study, 26 of 93 preschool children with a parental history of stuttering were classified as stutterers. Four years later, seven of these children were classified as persistent stutterers, and 16 children were classified as recovered stutte...

Objective data on the development of stuttering during its first several months are sparse. Such a deficit is due to parents' tendency to postpone professional consultation regarding early stuttering until later in the course of the disorder and to a lack of longitudinal studies beginning close to onset. This report presents information on a rare group of 16 preschool subjects who were evaluate...

OBJECTIVE The purpose of this study was to see whether participants who persist in their stutter have poorer sensitivity in a backward masking task compared to those participants who recover from their stutter. DESIGN The auditory sensitivity of 30 children who stutter was tested on absolute threshold, simultaneous masking, backward masking with a broadband and with a notched noise masker. Th...

This article reports a gender replication study of the P. T. Fox et al. (2000) performance correlation analysis of neural systems that distinguish between normal and stuttered speech in adult males. Positron-emission tomographic (PET) images of cerebral blood flow (CBF) were correlated with speech behavior scores obtained during PET imaging for 10 dextral female stuttering speakers and 10 dextr...

Preliminary Phase I and II trials for the Lidcombe Program of early stuttering intervention have found favorable outcomes and that the treatment is safe. Although speech-language pathologists (SLPs) often need to intervene with pre-schoolers' early stuttering, many of these children will recover at some time in the future without such intervention. Consequently, they need to know whether the Li...

PURPOSE In preschool children, we investigated whether expressive and receptive language, phonological, articulatory, and/or verbal working memory proficiencies aid in predicting eventual recovery or persistence of stuttering. METHODS Participants included 65 children, including 25 children who do not stutter (CWNS) and 40 who stutter (CWS) recruited at age 3;9-5;8. At initial testing, partic...
