In four studies, 60 two- and three-year-olds were studied in an elicited imitation task wherein the linguistic form of sentences was varied according to conjunction structure and pattern of redundancy deletion in conjunction reduction. Both factors were found to affect imitation. (Author/RM)

In this study the part of the sentence which constitutes what the speaker is talking about is called the topic" of the sentence, and the rest of the sentence is the comment", which provides new information about the topic. (Author/MB)

A study was undertaken to investigate which of ten constructions are available to children of various ages for expressing conditionality. A modified sentence completion test based on use of the ten constructions was designed, field-tested, and administered individually to 20 students in each of five grades: kindergarten and grades two, four, six,…

This paper outlines the syntactic structures which represent a stage in the cognitive development of children, and focusses on an aspect of cognitive development known as conservation. The cognitive components of conservation are presented as the primordial base for the set of syntactic structures which map or mirror them. Piaget proposed four…

The research reported is part of an investigation into the acquisition of grammar, using nonlinguistic information from situational and behavioral context to analyze the development of linguistic expression. Three children were seen for approximately 8 hours, every 6 weeks, in their homes, from the age of 19 months--soon after the earliest…

Contrasts the syntactic view of forward and backward deletion of base structure elements with the idea that pragmatic factors of situational redundancy and perceptual grouping account for conjunction reduction in children. (EKN)

Investigates the linguistic and cognitive aspects of the mastery of the time conjunctions "before" and "after" by young children. (EKN)

This investigation studied the development of the form and function of negative sentences, and how it relates to the input on negation that children receive from their parents. The data came from three children: two from a previous study (Bellugi) and one the son of the investigators. A detailed analysis was carried out of the syntactic form and…
