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 speech of each of eight children aged 15 to 24 months was monitored in an informal setting and analyzed for the imitation of nonsense words introduced by the experimenter. In a second session, objects were introduced as referents for the nonsense words. Results failed to support the two initial hypotheses, namely that children imitate in part…

The spontaneous speech of seven children was monitored for "wh" questions. The children were observed longitudinally from about age 24 to 36 months. The pattern of development with regard to the deletion of non-obligatory verbs revealed that "what,""where," and "who" questions presented increasing verb…

This monograph presents a descriptive analysis of the syntactic patterns in 16 corpora of word combinations from 11 infants learning either English (six children), Samoan, Finnish, Hebrew, or Swedish. The mean utterance lengths range up to about 1.7 morpehmes. There are both reanalyses of corpora in the literature and new corpora. The data…

The use of "wh" forms in questions asked by four children was recorded from age 22 to 36 months, and analyzed. In the emergence of "wh" forms, the children first asked identifying questions with "what" and "who," followed in order by (1) "wh" pronominal questions which ask for major sentence…

Sound-meaning correspondences produced by an infant were studied under conditions of early rampant homonymy (i.e., production by a very young child of a small set of noncontrastive surface forms or phonetic sequences to refer to objects/events that on the basis of adult standards require the production of numerous contrasting surface forms). The…

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…

The ontogenetic development of human vocal utterances and their role in early interaction processes were studied with a three-month-old baby. Recordings were made of infant vocalizations in the home and the sounds were classified. During a five-minute segment between the mother and infant, the infant produced 59 utterances, 93 percent of which had…

Presents various viewpoints on dual language acquisition by children. These include native language foundation, first-language monolinguals' vocabulary development, second-language learning, simultaneous acquisition strategies, television as a source of language learning, functions of language in discourse, analysis of conversation, syntax and…

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…
