Purpose: The purpose of this study was to compare physiological indices of sympathetic nervous system arousal recorded during fluent and stuttered utterances in a preschool children who stutter (CWS). Method: Twenty-two 4- to 5-year-old CWS participated in the experiment. We recorded children's skin conductance response amplitude and frequency,…

Purpose: The aim of this study is to investigate how speech fluency in typical and atypical speech is perceptually assessed by speech-language pathologists (SLPs). Our research questions were as follows: (a) How do SLPs rate fluency in speakers with and without neurological communication disorders? (b) Do they differentiate the speaker groups? and…

Purpose: The purpose of this study was to examine the influence of "phonotactic probability", which is the frequency of different sound segments and segment sequences, on the overall fluency with which words are produced by preschool children who stutter (CWS) as well as to determine whether it has an effect on the type of stuttered disfluency…

The paper summarizes recent thinking on several aspects of early childhood stuttering, including the acquisition of fluency in young children and its relationship to language acquisition, the relationship of normal childhood nonfluencies to early stuttering, stuttering's relationship to language acquisition, and psycholinguistic influences on…

This study examined word-finding ability, measured by accuracy and latency of response, in a group of eight preschool stutterers (mean age 4.2 years) and two groups of eight nonstutterers (mean age 4.4 years) matched according to age, gender, race, and receptive vocabulary. Results indicated that, as a group, preschool children who stutter and…

Experimental studies are reviewed in which stuttering and speech disfluency were subjected to response contingent stimuli (RCS). Research issues are discussed, including response-stimulus contiguity, subject awareness, behavior definitions, stimulus control of responses, subject variability, effects of RCS on nonstuttered speech parameters,…

This article explores the connections between conversation demands and the ability of children who stutter to maintain fluency. A model of conversation management useful both in assessment and intervention is introduced. The three-component model considers competencies at the utterance level, suprasegmental level, and discourse level. (Author/JDD)

Pressure buildup patterns preceding the onset of phonation were studied in 573 fluent utterances of 10 stutterers and in 552 utterances of 7 controls. Stutterers evidenced deviant patterns of subglottal pressure buildup and abrupt voice onsets more often than did controls; occurrence of jitter and shimmer did not differ significantly. (Author/JDD)

This paper reviews studies of conversational turn-management timing behaviors used by children who stutter and their parents. Temporal aspects of conversations between children who stutter and their parents do not differ significantly from parent-nonstuttering child conversations. Parental manipulation of speech rate and response-time latency may…

This study of 20 stuttering and 20 nonstuttering preschool children found that stuttering children scored lower on 7 out of 8 language measures, with no significant intergroup differences on articulation proficiency or fluency. There were few significant correlations between measures of stuttering rate, speaking rate, and language performance…

Several experiments that manipulate stuttering by the use of delayed auditory feedback (DAF) and the prolongation of speech are reported. In a study on six severe stutterers (aged 15 to 47), self monitoring as a source of reinforcement in the use of DAF reduced stuttering frequency. Stuttering frequency was investigated with six severe stutterers…

There is a relatively strong focus in the stuttering literature on the desirability of selected alterations in parental speech and language style in the management of early stuttering. In this article, the existing research support for such recommendations is evaluated, together with relevant research from the normal language acquisition…
