Linguistic Development in Stuttering Children

چکیده
Normal fluency errors usually appear during language development, especially during the transition between the stages of one-word and simple phrases. In cases of stuttering the speaker produces several involuntary repetitions of phonemes, syllables, or words. The speaker can also show phoneme prolongation or a complete interruption of speech production. Other abnormal fluency failures in stuttering include tension pauses and fragmented words. An individual with stuttering can show associated related behaviors and movements, including tremor, eye blinks, and hand movements, among others. Aim: To study the relationship between language development and organization and the presence of stuttering in children. Materials and Methods: Twenty children with stuttering, age ranging from 4 to 7 years old were studied. A matched control group of 20 children without stuttering and without a history of language impairment were also studied. For evaluating language development, all patients were analyzed using the SituationalDiscourseSemantic (SDS) Model. This model is a valuable tool for conducting naturalistic observation and descriptive assessment of language development. The SDS Model provides a detailed description of 3 language contexts (situational, discourse and semantic) in 10 levels of cognitive and linguistic organization. Results: In all contexts considered by the model of cognitive and linguistic organization used for this study, i.e. situational-discourse-semantic, a significantly higher frequency of language delay was demonstrated in stuttering patients, as compared with patients without stuttering. Furthermore, none of the patients present with stuttering showed an adequate level of language development. Conclusion: Children present with stuttering demonstrated a significantly higher frequency of delay in language development as compared with children without stuttering. From the results of this paper, it seems that a detailed evaluation of all aspects of cognitive and linguistic organization should be performed in children with stuttering. Moreover, it seems that speech intervention in stuttering children should address not only fluency, but also specific aspects of language development.

Parental language input to children at stuttering onset.
Many programs for the indirect management of stuttering in early childhood counsel adjustment of parental language models, which are presumed to play an exacerbating influence on vulnerable children's fluency. We examined the relative levels of linguistic demand in maternal language to stuttering and nonstuttering children, adjusted for each child's current level of linguistic development. No s...

This is the second in a series of reports concerning stuttering pre-school children enrolled in a longitudinal study; the first was Ryan (1992). Conversational samples of 20 stuttering and 20 non-stuttering pre-school children and their mothers were analysed for speaking rate, conversational speech acts, interruption, and linguistic complexity. Between-group analyses revealed few differences be...

This article describes the role of lexical acquisition in stuttering by examining the research on word learning and interactions between semantics and syntax in typically developing children and children who stutter. The potential effects of linguistic mismatches, or dysynchronies in language skills, on the possible onset and development of stuttering are discussed. The article concludes with a...
متن کاملPredicting stuttering from linguistic factors for German speakers in two age groups.
UNLABELLED Brown's factors [J. Speech Disorders 10 (1945) 181] predict the likely loci of disfluency in English-speaking adults who stutter. A word is more likely to be stuttered for these speakers if it is a content word, starts with a consonant, is positioned at the beginning of a sentence, and if it is a long word. These same factors were examined in native German-speaking children and adult...

Objective: Stuttering is a speech disorder that occurs with frequent and abnormal disruptions in speech, such as sound repetition, sound prolongation, and sound or airflow blockage. Although various hypotheses and factors have been introduced including cognitive and linguistic factors, the etiology of stuttering has not been fully understood. According to the vicious circle hypothesis, increase...
