Schaeffer (1997, 2000) argues that children lack knowledge of specificity because Dutch children omit determiners and fail to scramble pronouns. Avrutin & Brun (2001), however, find that Russian children place arguments correctly according to whether they are specific or non-specific. This paper investigates object agreement and specificity in…

A study by Brown and Fraser (1963) shows that children tend to use telegraphic speech, employing content and omitting function words. This limitation involves the grammatical or semantic complexity of the sentences. Braine (1963) attempted to formulate productive rules for the initial stages in the acquisition of syntax by identifying two classes…

This investigation studied the development of certain predicates called factives, such as "sad,""happy,""know," and "true," by studying the semantic effects of negation on the complements of both factive and non-factive predicates. The subjects were 60 children, divided into three age groups of ten boys and…

As may be seen from data collected during language observations of four children over a period of two and a half years, children's sentences are not simply flawed versions of adult counterparts, but seem to result from a different grammar. These data indicate that logical formatives, such as "even," and "only," are sentence-initial constituents.…
