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…

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…

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…

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…

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)

Predictors of language production skills were evaluated in 48 children and adolescents with Down syndrome and compared to 48 children matched for nonverbal mental age and mother's years of education. Comparison of two models found the model that incorporated comprehension performance (as well group membership, chronological age, cognition,…

This study of rapid picture naming by 20 normally developing children (mean age 11 years) found significant differences between two-and three-dimensional pictures for higher level vocabulary items, but not for lower-level vocabulary items, suggesting that dimensionality may be a critical feature for rapid lexical access for higher-level picture…

This review considers aspects of normal mental storage and retrieval, storage and retrieval in disordered word finding, possible causes of word finding disorders, and clinical implications in both storage and retrieval components. Implications call for attention to increasing word knowledge, storage strength, naming accuracy and speed, retrieval…

Three children with developmental apraxia of speech (DAS) identified syllables in words, judged intrasyllabic sound positions, and constructed syllable shapes within monosyllabic frames. Results suggest that DAS children demonstrate an apparent breakdown in the ability to perceive "syllableness" and to access and compare syllable…

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…

Stories were elicited from 20 closed-head-injured children (ages 100 to 194 months) and matched nonneurologically impaired accident victims. No significant differences were found between the groups on any of the measures of narrative ability (story grammar and intersentential cohesion). (Author/DB)

Comparison of English past-tense productivity in 31 school-age children with specific language impairment (SLI) and 31 children with no language (NL) impairment found SLI children made more errors, with a greater proportion resulting from overuse of unmarked grammatical forms (e.g., "go") than from suffixation (e.g., "goed"). Children with SLI…

Two studies compared the descriptions given by children (N=74) with and without autism of animated stimuli depicting mechanical launching effects, intentional reactions, or sequences of mechanical and intentional reactions. Although children with autism were as able as control groups at these differentiations, differences were found in their…

Two studies with nine children with severe traumatic brain injury (TBI) were conducted. Study 1, focusing on longitudinal changes in speaking rate, found markedly slower speaking rates for five subjects. Study 2, examining possible causes of slowed speaking rate, found that both reduced articulatory speed and increased pausing may contribute…
