Spencer, Caroline E. M.S., Purdue University, August 2013. Preschool Language and Phonological Proficiencies in Predicting Stuttering Recovery or Persistence. Major Professor: Christine Weber-Fox The purpose of this study was to investigate the relationship between expressive and receptive language, phonological, and verbal working memory proficiencies in the preschool years and eventual recove...

Stuttering is a speech disorder, with onset often occurring in the preschool years. The prevalence of stuttering in young children is much higher than that in the general population, suggesting a high rate of recovery. However, we are unable to predict which children will recover without treatment, and it is widely acknowledged that stuttering therapy during childhood provides the best safeguar...

A pallial-basal-ganglia-thalamic-pallial loop in songbirds is involved in vocal motor learning. Damage to its basal ganglia part, Area X, in adult zebra finches has been noted to have no strong effects on song and its function is unclear. Here we report that neurotoxic damage to adult Area X induced changes in singing tempo and global syllable sequencing in all animals, and considerably increas...

UNLABELLED This paper summarizes and discusses some of the key issues raised in the other four manuscripts in this special edition of Journal of Fluency Disorders. All the four pieces examine risk factors in developmental stuttering from different perspectives and all provide stand-alone contributions to knowledge on the subject. Thus, rather than review, the focus of the present paper is to hi...

OBJECTIVES Howell and Davis's (2011) model that predicts whether stuttering in eight-year old children will persist or recover by teenage was adapted for screening school-aged children for risk of stuttering. Stuttering-severity scores were used to predict whether children belonged to fluent or stuttering groups. Predicted group assignments were compared for models in which severity measures we...

Purpose A number of studies with large sample sizes have reported lower prevalence of stuttering in children with significant hearing loss compared to children without hearing loss. This study used a parent questionnaire to investigate the characteristics of stuttering (e.g., incidence, prevalence, and age of onset) in children who are hard of hearing (CHH). Method Three hundred three parents...

Objectives: It has been noted that stuttering is more prevalent in bilinguals than in monolinguals. The similarities of the languages involved have been mentioned to justify the difference between stuttering prevalence among bilingual and monolingual speakers. The aim of this study is to investigate the effect of language similarities on prevalence of stuttering among Kurdish-Farsi bilingual st...

Stuttering is a speech disorder that begins during the first years of life and is among the most prevalent of developmental disorders. It appears to be a problem with neural processing of speech involving genetics. Onset typically occurs during the first years of life, shortly after language development begins. Clinical presentation during childhood is interrupted and effortful speech productio...
