Children's development of the functional category of articles can be explained in two ways. One approach assumes that children are equipped with innate knowledge of the category, while the other assumes that children's early articles are limited-scope formulae. Using Eisenbeiss's (2000) criteria for determining the status of DPs, developed for a…

For adults, "no" and "not" change the truth-value of sentences they compose with. To investigate children's emerging understanding of these words, an experimenter hid a ball in a bucket or a truck, then gave an affirmative or negative clue (Experiment 1: "It's not in the bucket"; Experiment 2: "Is it in the…

This study investigates the emergence and development of the discourse-pragmatic functions of the Japanese subject markers "wa" and "ga" from a usage-based perspective (Tomasello, 2000). The use of each marker in longitudinal speech data for four Japanese children from 1;0 to 3;1 and their parents available in the CHILDES…

The study aims to account for the distribution of finite versus non-finite verbs during a developmental period when children use both types of verb forms in contexts requiring finiteness. To meet this goal, longitudinal samples from three Hebrew-acquiring children (aged 1;4-2;6) are examined from the onset of verb production and across the…

This study investigates prosodic (noun length) and lexical-semantic (animacy) influences on determiner use in the spontaneous speech of three children acquiring French, Austrian German and Dutch. In support of typological and language-specific hypotheses from the Germanic-Romance contrast, an advantage of monosyllabic nouns and of inanimate nouns…

The purposes of this study were to investigate (1) the level of development of four target vocal and gestural symbols (Doggie, Cup, Car, and Fiffin, a novel concept), and (2) the relationship of symbolic maturity to the use of symbols in combinations. Thirty infants (15 boys and 15 girls), between 82 and 91 weeks of age, were observed for…

Two issues in language development are explored--the emergence of the ability to communicate and the relationship between emerging forms and functions. Solutions to these problems involve the notion of interpretation and depend on the fact that adults interpret children's behaviors as if they were meaningful according to the adult system. The…

Words artificially isolated from 12 parents' speech to their children aged 1;10-3;0 were significantly less intelligible to adult listeners than words originally spoken to an adult. While parents did not adjust the clarity of words, their speech was more redundant in anticipation of the children's comprehension. Research implications are…

The development of forms and functions of negation in parent-child interactions in the early stages of language acquisition is discussed with illustrative examples from field data relating to two Tamil-speaking children and their parents. An attempt is made to provide a scheme for analyzing the negatives in children's speech. (18 references) (JL)

A study was undertaken to explore the relationship of mothers' language to infant development in terms of the infants' development of sensorimotor intelligence. Specifically, the study chronicled the infants' advances in sensorimotor development from J. Piaget's Stage II to Stage III as a possible explanation for changes in maternal language. It…

Child acquisition of Mandarin was studied with four middle class families from Taipei, Taiwan. The 2-year-olds were taped at home playing with their families. Two of the children were taped for short periods (7 hours and 9 hours), while the other two children were studied biweekly for 14 months, which resulted in 71 hours of transcribed child…

Patterns of speech from lower socioeconomic status mothers to their infants were analyzed to determine correlations with infant risk of mental retardation. Measures of maternal language included sentence form, amount of speech, and syntactic complexity. The proportion of imperatives was positively correlated with risk status and negatively…
