Reports a study of two- and three-year-olds' acquisition of complex sentences with perception and epistemic verbs that took a second verb in their complements. Complement types, complementizer connectives, and the discourse contexts in which complementation occurred were specific to individual matrix verbs. (Author/CB)

Analysis of mothers' pragmatic language use and children's language levels during free play sessions suggested that a mother-driven, direct influence model may be inappropriate for many mother speech-child language development relationships and points to the feasibility of child- and mother-driven explanatory models for indirect relationships.…

The development of a new parent report instrument, Inventario del Desarollo de Habilidades Communicativas, is reported and 5 studies carried out with the instrument for 328 children aged 8 months to 2 years/7 months are presented. Among the findings are similar trajectories of development for Spanish- and English-speaking children and for children…

Word learning by young children is viewed as a problem deriving from the use of forms of discourse texts. Uses of causal and temporal terms in private speech by a child studied longitudinally from 1;9 to 3;0 are analyzed from this perspective. (Contains 38 references.) (JL)

Assessed long-term predictive validity of the MacArthur Communicative Development Inventories: Words and Sentences (CDI:WS) for children's expressive and receptive vocabulary development. Sixty-one New Zealand children were assessed with a New Zealand version of the CDI, and with the Expressive Vocabulary Test and Peabody Picture Vocabulary…

Explores the possibility that particular properties of how number words are used within sentences inform children of the semantic class to which they belong. Analysis of transcripts of the spontaneous speech of three children and their parents suggests that the relevant cues are available as input in parents' speech to children and that children…

Investigates acquisition of the rhyme using cross-sectional and longitudinal data from 14 English-speaking children between 1- and 2-years of age. Focuses on four questions pertaining to rhyme development that are motivated from current theories of prosodic acquisition. (Author/VWL)

Studied the case of bilingual acquisition across two modalities to examine diverging hypotheses about the types of knowledge underlying early bilingualism. Three children acquiring Langues des Signes Quebecoise and French, and three children acquiring French and English were videotaped over a year while novel and familiar speakers of each child's…

Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3 and 4 were investigated in 34 late talkers with normal receptive language and in 16 typically developing comparison children matched on age, socioeconomic status, and nonverbal ability. Late talkers made greater gains than comparison children between…

Describes the phonological acquisition of 129 monolingual Putonghua-speaking children, aged 1.6 to 4.6 years. Children's errors suggested that Putonghua-speaking children master four elements of Putonghua syllables in this order: (1) tones; (2) syllable-initial consonants; (3) vowels; and (4) syllable-final consonants. Suggests that the saliency…

The influence of information level on the production of accuracy of 20 children was examined. Data were children's productions of nouns in sets of utterances referring to triplets of pictures representing noun-verb-noun utterances. (Author/JL)

This paper outlines the degree to which age and verb vocabulary size are predictive of changes in the reported usage of English verbs that are irregular in their past tense form in a sample of more than 1,000 children. (Contains 40 references.) (JL)

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)

Describes two experiments using apparent contradictions of the form "Did you like your supper:--I did and I didn't" to show that non-set theoretic interpretive structures are accessible to adults and 3-year-olds. (17 references) (Author/CK)

Investigation of the acquisition of Tamil verb inflections in three two-year-old children revealed a high percentage of usage of verb inflections indicating tense, aspect, modality, person, number, and gender. Explanations for this early, almost error-free language acquisition are explored in terms of the facilitating properties of agglutinating…
