Flexibility and productivity are hallmarks of human language use. Competent speakers have the capacity to use the words they know to serve a variety of communicative functions, to refer to new and varied exemplars of the categories to which words refer, and in new and varied combinations with other words. When and how children achieve this…

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 book focuses on the nature and development of knowledge concerning grammar and the meanings coded by grammar. This knowledge is inferred from performance, from sentences and the settings in which they are spoken, and from signs of comprehension or incomprehension of sentences by preschool children. The first two stages of linguistic…

Fourteen specifically language-impaired children, age four to seven, pointed to pictures in, and acted out, semantically reversible sentences that varied in thematic content and in the order of thematic roles. Compared to children matched on language age and chronological age, subjects' comprehension was significantly lower. (Author/JDD)

The syntactic properties of the child's language are studied. Within the framework of transformational grammar, the rules of syntax can be divided into three types: base- or phrase-structure rules, transformational rules, and morphological rules. Each of these rules is discussed. It is stated that the one process that appears to characterize each…
