This paper discusses C. Chomsky's 1969 paper on children's syntactic development and the subsequent studies made to test her findings. Later studies indicate that Chomsky's results were not clearly differentiated, and a slight alteration in procedure changes results significantly. (CHK)

Vocalizations of two female infants, recorded over a five-week period after the first emergence of cooing were studied. It was found that the features of the more primitive sound types regrouped themselves in comfort sounds. The implications for theories of prespeech development are discussed. (EJS)

The development of plurals in two German-speaking children was analyzed, based on observational data. It was argued that the children were learning plurals by rote, conditioned by morphological complexity which cannot be subsumed under any general rule. (Author/NCR)

This article discusses the popular belief that girls are more advanced in language development than boys. (Author/NCR)

Spontaneous full passives and related constructions from 234 children, aged 2 to 13, and elicited passives from 262 college students were analyzed. The agentive non-reversible did not appear until after age 9; and until age 11 no child produced both reversible and non-reversible passives. (Author/SW)

Focus is one factor that may account for children's use of single-word utterances after they have acquired the use of multi-word utterances. The possible role that focus may play in children's use of single-word utterances in naturalistic settings, after the acquisition of syntax, was investigated. (SW)

Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Describes a study that investigates the order of acquisition of case-marked pronouns in Hebrew among 105 children between two and five years of age. Results indicate that children begin using case-marked pronouns as early as age two and that the stage of morphological development parallels that of English-speaking children. (SED)

Ostensive definitions of words are ambiguities as to their referent. In a study of infant-mother dyads engaged in looking at picture books, 95 percent of ostensive definitions referred to the whole object depicted rather than parts, attributes, or actions. When parts were named, ambiguity was avoided by naming the part and the whole. (PJM)

In a study of early functions of negation (rejection and denial), 48 children under age 3 were asked easy yes/no questions. The most likely age range for the appearance of error-free denial "no" at 1 year/8 months to 2 years/1 month supports the continuity theory of negation development. (Contains 27 references.)

Reviews the proceedings of a 1971 conference on the relationships between speech and learning to read, and discusses related literature and research under these topics: acquisition of speech and reading, the deaf child's language acquisition, orthography and linguistic awareness, reading maturity and age: short-term memory, and attaining fluent…

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

The purpose of the paper was to map the language development of children at infant school and examine spontaneous corrections made by the children of their speech. (Author/NCR)

The present investigation examines three hypotheses concerning the development of temporal coordination of consonant clusters in the speech of children at four age levels. Results reveal that five and seven-year-olds can be separated from older children and adults on the basis of absolute duration of consonants. (CHK)

Data on the acquisition of lexical tone were collected from 17 Mandarin-speaking children. Among other results, it was found that: (1) tone is acquired relatively quickly; (2) mastery of tones occurs well before mastery of segmentals; and (3) Mandarin high-level and falling tones are acquired before rising and dipping tones.
