This study utilized the head-turn preference procedure in four experiments to determine whether 1-year-old infants could extract and remember information from auditory strings produced by miniature artificial grammar. Findings indicated that subjects generalized to the new structure by discriminating new grammatical strings from ungrammatical ones…

Analyzes different strategies used by speakers/writers and hearers/readers to deal with underspecified coherence relations, phrased in terms of Horn's (1984) Q- and R- principle. Presents data from the psycholinguistic literature on the interpretation of underspecified relations and data from language-acquisition research suggesting that both…

An account of grammatical acquisition is developed within the parameter setting framework applied to a generalized categorical grammar (GCG). Computational simulation shows that several resulting acquisition procedures are effective on a parameter set expressing major typological distinctions based on constituent order, and defining 70 distinct…

This study explored the sensitivity of 20 10- to 11-month-old infants to the phonological characteristics of their native language. Tone-probe event-related potentials were obtained for subjects listening to a story, either with normal English function morphemes or modified with atypical function morphemes. Results suggest that the 11-month-olds,…

Reports on a study into the acquisition of Welsh and English phonology in Welsh-English bilingual children. Concentrates on the acquisition of the rhotic consonants--the trilled -r of Welsh and the approximant -r of English. (Author/VWL)

Two studies examined word frequencies in toddlers' lexicons using the Language Development Survey (LDS). In Study 1, a high degree of consistency in LDS word frequencies was found in the lexicons of 758 24-month-olds. In Study 2, LDS word frequencies in 40 late talkers found both lexicon size and age of subject influenced the degree of consistency…

Looks at what William Stokoe taught educators about teaching deaf children. Among his ideas were that signing is more than just a away to communicate, deaf children should begin to acquire sign language during their infant years, teaching begins with a commitment to one's beliefs, good teachers are innovative thinkers, and it is important to look…

Different interactions of two common phenomena--final consonant omission and vowel lengthening before voiced consonants--are examined with a focus on a case study of two young children with phonological delays in their acquisition of English. Argues that at least some developmental opacity effects support sympathy and that such effects emerge in…

Examined use of word order and animacy for interpretation of sentences by typically-developing and language delayed children. Results indicate that typically-developing 2-year-olds use neither cue consistently to interpret sentences; typically-developing 2.5-year-olds used a coalition of word order and animacy cues; and language-delayed…

Comparison of the performance of 25 subjects with autism and 25 nonautistic subjects with mental retardation found all subjects able to comprehend the personal pronouns "I,""you," and "me." However, autistic subjects were less likely to employ the pronoun "me" in a visual perspective-taking task and to say "you" to refer to the experimenter.…

Describes an ethnographic study of African American toddlers and families that focused on children's productive competence in naturally occurring narrativelike conversation. Examines emergence of narrative competence; posits definition incorporating minimal requirements for child participation within the fundamental essence of narrative structure.…

Examined two-year-olds' word learning. In one study, adults modeled the new word for an object novel to the children; in another, the object was novel only for the adult. Subjects displayed significant learning of new words in both settings, suggesting that toddlers understand that novelty in a discourse setting is determined from the speaker's…

Responds to a previous article on emergentism, connectionism, and language learning. Suggests that connectionist models of emergent language knowledge will continue to be important in the years to come. (Author/JL)

Investigates how the noun and verb classes develop in the free speech of a French child between the ages of 1 year, 2 months to 2 years and 6 months from the perspective of semantic and grammatical development. Analyses indicate that in French acquisition, nouns clearly predominate over verbs until 20 months of age at least, but that verbs are…

Investigated whether infants can construe the same set of objects as an object category or as embodying an object property. Results of 2 experiments involving 48 and 64 14-month-olds respectively suggest that infants have begun to distinguish nouns from adjectives, they expect different grammatical forms to highlight different aspects, and that…
