Purpose: To determine whether stuttering judgment accuracy is influenced by familiarity with the stuttering speaker's language. Method: Audiovisual 7-min speech samples from nine 3- to 5-year-olds were used. Icelandic children who stutter (CWS), preselected for different levels of stuttering, were subdivided into 5-s intervals. Ten experienced…

Purpose: Relatively recent research documents that visual choral speech, which represents an externally generated form of synchronous visual speech feedback, significantly enhanced fluency in those who stutter. As a consequence, it was hypothesized that self-generated synchronous and asynchronous visual speech feedback would likewise enhance…

This dissertation study explored the efficacy of the SpeechEasy[R] device for individuals who are gainfully employed stutterers and who participated in workplace education learning activities. This study attempted to fill a gap in the literature regarding efficacy of the SpeechEasy[R] device. It employed a qualitative multiple unit case study…

Several studies of utterance planning and attention processes in stuttering have raised the prospect of working memory involvement in the disorder. In this paper, potential connections between stuttering and two elements of Baddeley's [Baddeley, A. D. (2003). "Working memory: Looking back and looking forward." "Neuroscience," 4, 829-839] working…

This paper is the second in a series of two articles exploring subtypes of stuttering, and it addresses the question of whether and how language ability and temperament variables may be relevant to the study of subtypes within the larger population of children who stutter. Despite observations of varied profiles among young children who stutter,…

This study investigated the maintenance of attention and adaptation to background stimuli of preschool children who do (CWS) and do not stutter (CWNS). Participants were 13 monolingual, Standard American English speaking, 3-5-year-old CWS and 14 CWNS. Results indicated that CWS were significantly more apt than CWNS to attend to or look at changes…

The impact of observable increases in stress during moments of stuttering has long been an interesting area of research. Although stuttering type, severity, and associated behaviors may vary widely among individuals, it is not uncommon to find stress management, relaxation, and desensitization incorporated into the therapeutic remediation of…

Purpose: This study investigated peer responses to preschoolers' stuttering in preschool and sought to determine whether specific characteristics of participants' stuttering patterns elicited negative peer responses. Method: Four outdoor free-play sessions of 4 preschoolers age 3-4 years who stutter were videotaped. Stutters were identified on…

Purpose: To investigate the efficacy of parent-child interaction therapy (PCIT) with young children who stutter. Method: This is a longitudinal, multiple single-subject study. The participants were 6 children aged 3;3-4;10 [years;months] who had been stuttering for longer than 12 months. Therapy consisted of 6 sessions of clinic-based therapy and…

The specific mechanisms that underlie childhood stuttering are not fully understood. The current study investigated these mechanisms by comparing the effect on fluency of priming different components of a short sentence. The main findings were that: (1) both children who stutter (CWS) (n = 12, M age = 6;3) and children who do not stutter (CWNS) (n…

The present study investigated the dysfluencies in the speech of nine French speaking individuals with fragile X syndrome. Type, number, and loci of dysfluencies were analysed. The study confirms that dysfluencies are a common feature of the speech of individuals with fragile X syndrome but also indicates that the dysfluency pattern displayed is…

Previous studies suggest that anatomical anomalies [Foundas, A. L., Bollich, A. M., Corey, D. M., Hurley, M., & Heilman, K. M. (2001). "Anomalous anatomy of speech-language areas in adults with persistent developmental stuttering." "Neurology," 57, 207-215; Foundas, A. L., Corey, D. M., Angeles, V., Bollich, A. M., Crabtree-Hartman, E., & Heilman,…

Van Borsel, Dor, and Rondal (2007) examined the speech of seven boys and two young male adults with fragile X syndrome and considered whether their speech was comparable to that reported in the developmental stuttering literature. They listed five criteria which led them to conclude that the speech patterns of speakers with fragile X syndrome…

Several recent studies have suggested that young children who stutter (CWS) tend to show depressed lexical performance relative to peers. Given the developmental literature as well as several studies of verb processing in individuals who stutter, verbs may pose a particular challenge for this group. The purpose of the present study was to examine…

Genome-wide linkage and association analyses were conducted to identify genetic determinants of stuttering in a founder population in which 48 individuals affected with stuttering are connected in a single 232-person genealogy. A novel approach was devised to account for all necessary relationships to enable multipoint linkage analysis. Regions…
