Questioning others is one of the most powerful methods that children use to learn about the world. How does questioning develop? How is it socialized? And how can questioning be leveraged to support learning and education? In this volume, some of the world's leading experts are brought together to explore critical issues in the development of…

This volume presents the findings of a large-scale study of individual differences in spoken (and heard) language development during the school years. The goal of the study was to investigate the degree to which language abilities at school entry were stable over time and influential in the child's overall success in important aspects of…

Providing a comprehensive survey of cutting-edge work on second language learning, this "Handbook," written by a team of leading experts, surveys the nature of second language learning and its implications for teaching. Prominent theories and methods from linguistics, psycholinguistics, processing-based, and cognitive approaches are…

The development of early vocalizations was investigated with 13 infants who had Down's syndrome and 27 infants developing normally, at bimonthly intervals from 4 to 18 months of age. Both groups demonstrated increased production of mature syllables over time as well as large variations in vocal development, both within and across groups and across…

This study compared 2 naturalistic language intervention methods--milieu teaching and responsive interaction--in 6 preschool classrooms that included 36 children with moderate to severe language disabilities. Although no main effects for treatment were found, milieu teaching was more effective with children having the lowest language levels and…

This observational study examined the development and use of communication in a pair of deaf and hearing monozygotic twins from 13 to 36 months of age. Both children were enrolled in a total communication preschool program. In contrast to the hearing twin, the deaf twin used imitative (rather than responsive) signs and gestures. (Author/DB)

The relationship between language and symbolic play was studied in a sample of children identified as referential in style (multiple noun utterances exceeded pronoun or no-noun utterances), as compared with a sample identified as expressive in style (pronoun utterances or no-noun utterances exceeded multiple noun utterances). Children were…

This study evaluated the effectiveness of Prelinguistic Milieu Teaching for toddlers (n=39) with intellectual disabilities and responsivity education for their parents as a means of facilitating children's communication and language production skills. Comparison of parent child pairs receiving or not receiving the intervention found the…

This study found that word learning ability in only 10 of 20 children (ages 7-10) with hearing impairment (HI) was comparable to performance of 20 hearing children matched for receptive vocabulary knowledge. Degree of hearing loss was not related to language or word-learning abilities. Results suggest the coexistence of a language impairment for…

Focuses on a single rule of grammar to produce evidence of a memory system for language acquisition and processing that is modular; independent of real-world meaning; unaffected by frequency and similarity; sensitive to formal distinctions; more sophisticated than the explicitly-taught rules it subsumes; developed independently of ambient input;…

Sign language production of 14 low-functioning students (ages 9 to 20) with autistic disorder were examined. The location aspect of signs was produced more accurately by subjects than either the handshape or movement aspects. Wide individual differences were observed. Sign vocabulary size and accuracy was correlated with performance on two…

Examines questions related to whether children with severe learning disabilities go through the same developmental stages as children without such problems, or whether they develop along different lines. Explores the "delay" versus "deviance" issue in relation to linguistic development in children with Down's syndrome. Looks…

Reports on a longitudinal study on the effects of students' early linguistic development and family background on test performance when the students reach the end of their compulsory schooling years. Finds a considerable degree of continuity between early language development and later examination performance. (CFR)
