Compared the effects of negative evidence versus positive input on the acquisition of irregular past-tense verb forms. Young children from two London nursery schools participated in a within-subjects design over five weeks. Results indicated that improvements in the grammaticality of child speech were considerably greater in cases where negative…

This reprinted article discusses the overemphasis of sign language, which contributes to their isolation, in teaching students with deafness. Teachers are urged to avoid signing in the classroom when spelling on fingers or using written language will convey the same information. (CR)

This reprinted article from 1899 argues against the abolition of sign language in the classrooms of students with deafness. It also discusses the benefits of sign language and the ability of sign language to explain words and to convey information. (CR)

This study examined developmental characteristics of 82 deaf and hard-of-hearing children identified through the high-risk registry in Colorado either before or after 6 months of age. Children identified early and receiving intervention two to three months after identification had significantly higher levels of receptive and expressive language,…

This study evaluated a method of adult mediation with a deaf second grader which involved identification of language needs through transcription and analysis of the child's retellings of weekly basal stories, followed by targeted adult-mediated conversations. Evaluation indicated the student's performance on targeted semantic and syntactic…

Discusses the nature of speech perceptual capacities that infants possess, changes that come about with increased exposure to language, how growing understanding of native-language sound organization is used in developing word-segmentation strategies, and how developing word-segmentation abilities may facilitate discovery of grammatical…

Two experiments examined infants' reliance on object shape versus color for word generalization to animate and inanimate objects. Infants were taught labels for either novel vehicles or novel animals using preferential-looking procedure or an interactive procedure. Results of both experiments indicated that infants limited their word…

This 14-year prospective, longitudinal study of children with (n=114) and without (n=128) speech and/or language impairments found (1) high rates of continued communication difficulties; (2) considerable stability in language performance over time; and (3) better long-term outcomes for those with initial speech impairments than for those with…

Describes the rationale and development of a new screening test, Developmental Indicators for the Assessment of Learning-3 (DIAL-3), which is based on previous editions. Empirical research is presented to document item additions and deletions as well as the continued maintenance of three performance areas: motor, concepts, and language. (Author/CR)

Reviews claims proposing that knowledge of American Sign Language (ASL) facilitates reading development in deaf children. It offers support for one such claim although it argues that the relationship does not develop naturally but must be cultivated through experiences that serve to direct attention to correspondences between different language…

Three studies tested the hypothesis that children's difficulty acquiring dimensional adjectives, such as big and little, is a consequence of how these words are used by adults. Findings indicated that children easily acquired novel dimension words when such words were used in a strictly comparative fashion, but had difficulty when also exposed to…

This article presents information about the auditory and speech development of infants with normal hearing and those who are deaf or hard of hearing. Methods of assessing hearing, evidence of auditory learning prior to birth, behavior assessment procedures, hearing aid use, and early identification and speech development are discussed. (Contains…

Reviews the hypothesis, "phonological bootstrapping," that a purely phonological analysis of the speech signal may allow infants to start acquiring the lexicon and syntax of their native language. Study presents a model of phonological bootstrapping of the lexicon and syntax that helps illustrate the congruence between problems. Article argues…

This study examines the processes underlying vocabulary acquisition, i.e., how new words are learned, in children with Williams Syndrome, a rare neurodevelopmental disorder. A Williams Syndrome group was compared to groups of normal controls in the range 3-9 years in four different experiments testing for constraints on word learning. (Author/JL)

This study compared effects of two styles of storybook reading on the interpretations of two preschool children experiencing delayed language development. One used expansions and cloze procedures; the other provided questions and modeling of appropriate answers. Children produced more answers to questions, more interpretations, and more complex…
