The study investigated the reaction times in the fluent speech utterances of 20 adult stutterers and 20 nonstutterers. Results indicated that reaction times for longer utterances and for utterances requiring minimal preparation were longer for stutterers than for nonstutterers, suggesting stutterers may have difficulty in motor programing of…

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

Cohesion strategies used by three normal and three head-injured adults were examined in both conversational and narrative conditions. Head-injured subjects used different cohesion patterns than normal adults in both conditions; and both groups used different cohesion patterns in the conversational and narrative conditions.

Comparison of rapid automatized naming in 136 children and youth with primary language disorders and 2,450 typical children and youth found naming time (but not accuracy) differed significantly between groups, especially in the color-shape naming task. Findings indicate that the requirements for two-dimensional, continuous naming resulted in…

Aphasic (N=15) and non-brain-damaged adults listened to and retold two narrative stories three times in succession. Both aphasic and non-brain-damaged subjects were affected by story structure and increased the amount of information retold across retellings. Non-brain-damaged subjects retold slightly more (statistically insignificant) information…

Twenty-four relatively high-functioning children and adolescents with autism were compared to typically developing children (matched for nonverbal mental age and language level) on three tasks designed to assess the presence of cognitive social scripts. Results indicated that basic scriptal knowledge was intact, but that reliable differences in…

Among results of a comparison of 20 language disordered and 20 control children (ages 7-10) were that only the nonhandicapped children changed the number of complete episodes narrated as a function of the listener's shared information, while neither group altered the accuracy of conjunctive use as a function of the listener.

Comparison of alpha amplitudes of 12 children with learning disabilities and 12 normally achieving controls in three task situations found no significant differences between groups in alpha amplitude but a significant task effect with the vigilance, story comprehension, and rehearsal conditions showing decreasing alpha amplitudes in both groups of…

Investigation of the impact of speaking rate variations in the linguistic input provided to 32 school-age children (half with specific language impairment (SLI) found both SLI and typical children had similar recognition accuracy, but SLI children had significantly more difficulty with the production of novel words presented at a fast rate.…

This study developed a multidimensional topic analysis sensitive to patterns in topic management appropriate for use with head-injured adults. Language samples of a closed-head-injured adult and a matched normal adult were compared. Results demonstrated the analysis' potential to reliably identify, quantify, and describe differences between…

This study compared the relative use by four male and four female youth with mental retardation of linguistic (grammatical) devices identified as characteristic of typical female speech (qualifying markers, question styles, and politeness terms). Females produced significantly more qualifying markers than did males, although neither question style…

This study compared the relationship between acoustic parameters and listeners' perceptions of intonation contours produced by 12 children (ages 7-14) either with severe-to-profound hearing impairments (HI) or normal-hearing (NH). The HI children's productions were generally similar to the NH children in that they used fundamental frequency,…

This study examined the influence of argument-MA-structure complexity on the omission of auxiliary "be" verbs in 30 children with specific language impairment (SLI). Results indicated that the children with SLI and controls matched for mean length of utterance were more likely to omit the auxiliary forms when attempting sentences with greater…

The concurrent and predictive relations of sensorimotor behavior and play to language in the second year were assessed among 19 preterm and 20 full-term infants tested at 13 1/2 and 22 months of age. Numerous associations between play and language were identified; sensorimotor behavior and language in the same age period were relatively loosely…

Two studies examined the relationship between speech perception and speech production errors in children (N=21 and ages 5 and 7) with articulation disorders. Findings indicated the existence of a subgroup of articulation disordered children for whom production errors reflect perception errors. (Author/DB)
