This study compared the science vocabulary performance of 76 students with learning disabilities (LD) and 78 normally achieving (NA) students at elementary and intermediate grade levels. Findings indicated significant differences in receptive language performance between LD and NA students and differences in expressive language between older and…

Two children (ages four and five) with word-finding deficits characterized largely by semantic substitutions participated in a treatment involving phonological information about target words. Treatment resulted in reduction not only of occasional phonological word-finding substitutions but also of the large number of semantic word-finding…

Forty-eight subjects (grades 1-12) with phonological disorders were identified and categorized into either Residual or Delayed groups and performance was compared with that of 24 normal individuals on various speech and language parameters. Results indicated that voice disorders, deficits in expressive language, and hearing problems occurred more…

This study, with 30 language learning-disabled, reading-disabled, and normal primary school children, found that clause structure complexity, fluency, and grammatical and phonemic accuracy tended to be highest when children were discussing absent referents, providing explanations and stories, and giving unshared information. These effects were…

This study compared the effect of productivity (a correlate of suffix frequency) on derivational suffix use in 69 elementary and middle school students' derivational suffix use. Twenty-three students had language-learning disabilities (LLD). Students with and without LLD used highly productive suffixes but LLD students were less accurate in…

This study of the forms and functions of expressive communication produced by 84 children and adults with severe mental retardation found significant differences among participants associated with differences in their communication levels (contact gesture, distal gesture, or symbolic), age (child or adult), and residential status (community home…

Discusses how speech-language pathologists can use photography to encourage more active language expression in children with language and learning disabilities, and describes seven categories for photography use in language learning environments. Each photo project includes suggested language objectives, applications, and advantages. (Author/CR)

Twenty-six children and adolescents who were unable to produce /r/ correctly listened to a tape of 200 words containing /r/ spoken, either correctly or incorrectly, by either the subjects themselves or another speaker. Subjects judged both the correctness of the /r/ and the speaker's identity. Results support a relationship between speech…

This study used longitudinal productivity criteria to establish the phonetic skill of 20 children (followed from 9 to 16 months). The number of specific consonants produced consistently across the months predicted referential lexical use at 16 months. Prior use of at least two supraglottal consonants characterized the children achieving…

Investigated the interface of form and function in the acquisition of negation in Cantonese-speaking children. Data--from the Hong Kong Cantonese Child Language Corpus--were longitudinal spontaneous samples of eight children aged 1.5 to 3.8 years. Main issues in the study were the sequence of emergence of negative markers and the acquisition of 11…

Comparison of spontaneous language samples of 30 toddlers diagnosed with specific expressive language impairment (SLI) and language samples of typically developing toddlers found the SLI toddlers vocalized significantly less often, had proportionately smaller consonantal and vowel inventories, and used a more restricted and less mature array of…

The acquisition of movement skills in American Sign Language was examined longitudinally in young children, one deaf and eight hearing, of deaf parents. Although production accuracy did not improve over the 5 to 14 months of the study's duration, the number and complexity of movements produced by the children did increase. Contacting action was…

Spoken language in 330 children with Down syndrome (ages 1-5) and 336 normally developing children (ages 1,2) was compared. Growth trends, individual variation, sex differences, and performance on vocabulary, pragmatic, and grammar scales as well as maximum length of utterance were explored. Three- and four-year-old Down syndrome children…

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…

This study examined possible relationships between young children's prelinguistic communication behaviors and subsequent (12 months later) expressive and receptive language outcomes. Results indicated that rate of intentional nonverbal communication initially was a predictor of spontaneous word productions later. (Contains references.) (Author/DB)
