This study examined intrajudge and interjudge agreement for the Lidcombe Behavioral Data Language (LBDL), a behaviorally based stuttering taxonomy. Ten experienced speech language pathologists and 10 undergraduates applied the LBDL to stuttered speech on two occasions. Intrajudge agreement was high for both groups, but only the experienced judges…

A questionnaire asking respondents to list adjectives describing four hypothetical stutterers (a female child, male child, female adult, and male adult) was completed by 42 school administrators in Alabama, Louisiana, Texas, and West Virginia. The majority of reported adjectives were negative stereotypical personality traits. (Author/JDD)

This study examined speech disfluency clusters in the speech of 60 3- to 6-year-old children, half of whom stuttered. Results indicated that the children who stuttered produced significantly more "stuttering-stuttering" clusters and significantly more "stuttering-repair" clusters, whereas nonstutterers never produced "stuttering-stuttering"…

Analysis of pedigrees from parents of 69 preschool children who stuttered revealed that more male than female relatives ever stuttered but that female subjects who stuttered had more female relatives who ever stuttered than did male subjects. Segregation analyses suggest that transmission of a single major genetic locus increases the liability to…

This study of 21 children (ages 4-6) found that children with stuttering and disordered phonology produced more sound prolongations and fewer iterations per whole-word repetition than did children who stuttered but had normal phonology. No differences were noted between children with stuttering and disordered phonology and children with disordered…

Two experiments investigating interval-by-interval interjudge and intrajudge agreement for stuttered and nonstuttered speech intervals found that training of judges could improve reliability levels; judges with relatively high intrajudge agreement also showed relatively higher interjudge agreement; and interval-by-interval interjudge agreement was…

Of 169 adult and adolescent stutterers studied, 112 reported family history of stuttering. Only 3 of the 112 reported birth or early childhood factors that might precipitate stuttering, as opposed to 21 of those without family history of stuttering. By considering these two conditions as separate factors in behavior, stutterers may be divided into…

This study compared verbal disfluency and accessory characteristics of 15 African-American and 15 White male stutterers (ages 8-12). Overall, no significant differences were found in verbal- or visual-disfluency behaviors on either reading or conversation tasks between the two groups. Also, no significant differences were found in attitudes toward…

Researchers studied the effects of self-modeling as an intervention for stuttering in school-aged students. Students viewed videotapes of themselves speaking fluently over a six-week period. All students evidenced a decrease in stuttering after viewing tapes. The increased fluency generalized to social settings. Results replicate those of an…

Seventy-nine children (ages 3 through 7) were asked to discriminate between the speech (fluent and disfluent) of two puppets, identify the one who "speaks like you," and evaluate their speech. Children from age 3 showed evidence of some awareness of disfluencies but most children reached full awareness at 5. Negative evaluation of…

Twelve adult males who stutter and 12 controls were tested on naming words and symbols and their ability to encode and retrieve memory representations of a combination of a symbol and a word. Findings question the claim that people who stutter have problems in creating abstract motor plans for speech. (Author/DB)

This study evaluated the language abilities of 15 young children with early stuttering symptoms and parents' views of the children's communicative development. Results indicated generally depressed performance on all child speech and language measures by the children who stutter. Parent report was closely attuned to measured child performance.…

This study examined the levels of linguistic demand in maternal language to stuttering and nonstuttering children. No significant or observable differences were detected in the relative level of linguistic demand posed by parents of stuttering children very close to onset of symptoms. Results do not support theories that parental language demands…

We investigated the role of delayed cerebral maturation, hemisphere asymmetry and regional differences in children with stuttering and healthy controls during resting state and hyperventilation, using conventional EEG techniques and quantitative EEG (QEEG) analysis. This cross-sectional case control study included 26 children with stuttering and…

Purpose: The purpose of this study was to investigate chorus reading's (CR's) effect on speech effort during oral reading by adult stuttering speakers and control participants. The effect of a speech effort measurement highlighting strategy was also investigated. Method: Twelve persistent stuttering (PS) adults and 12 normally fluent control…
