Noncomprehension signaling by 16 school-age children with mild mental retardation was compared with performance of 16 typically developing children matched for nonverbal mental age. Message type and speaker were manipulated in a direction-following task. Message type, not speaker, influenced noncomprehension signaling, with no intergroup…

Eight preschoolers with moderate developmental disabilities were paired with typically developing peers who had been taught simple strategies to facilitate communicative attempts. Consistent improvements in social interaction by trained peers and target children were demonstrated. These improvements generalized when trained peers were assigned to…

Two studies found positive effects of peer modeling upon the play scripts of preschool children with specific language impairment (SLI). The first study involved dyadic play sessions in which children with SLI were paired with a normal language peer model. The second study compared dyads of either two SLI children or one SLI child and one normal…

This study examined the productivity and representation of past-tense marking by 11 6-year-old children with and 22 children without specific language impairment (SLI). Patterns of past-tense marking as a function of a word's phonological composition and inflectional frequency were the same for the SLI children and the 11 control children matched…

Thirty 4- and 5-year-olds with specific language impairment (SLI) and 30 normally developing peers participated in a discrimination learning-shift paradigm. Both groups were equally successful in extracting regularities from recurring nonverbal stimuli and in making shifts. Findings failed to provide evidence that children with SLI are less able…

Listeners compared 10 individuals' suitability of speech at three stages of treatment for stuttering (before, immediately after, and six months after) with 10 non-stutterers. Ten speaking situations with different demands were rated using a newly developed instrument. Results indicated the instrument can be scored reliably and the factor…

This study investigated whether syntactic complexity exerts an influence on the frequency of stuttering in the speech of seven adolescents who stuttered and seven who were normally fluent. Although normal disfluencies and errors in repetition accuracy increased as syntactic complexity increased, stuttering frequency did not appear to be affected…

Clause, syllable, and response latency characteristics of conversational utterances were assessed in 14 boys who stuttered and 14 normally fluent boys. Findings suggest that changes in the number of clausal constituents that must be constructed, stored, or coordinated within an utterance may influence the likelihood of speech errors and, hence,…

A time-out from speaking contingency was evaluated in the treatment of stuttering in three school-age children. A red light time-out signal appeared for five seconds when the child stuttered. Two of the children responded to time-out with clear reductions in stuttering. Listeners did not detect any differences between the perceptually stutter-free…

Annual evaluation of the speech perception performance of 34 prelingually deafened children, grouped into those who received cochlear implants either before or after age 5, found open-set word recognition performance was significantly better for children implanted before age 5. Amount of daily use of the implant significantly affected all measures…
