Two groups of preschoolers and one of young grade-schoolers were tested for their comprehension of presuppositions and negation in complex syntax. Four types of sentences were presented: affirmative and negative versions of sentences with factive main predicates (which presuppose the truth of the proposition of the complement clause) and with…

This experiment used two groups of preschoolers and one group of young grade-schoolers to test for their comprehension of presuppositions and negation in complex syntax. (NCR)

Five experiments are carried out to determine the comprehension of passives by children. Results obtained demonstrate that comprehension rests on knowledge of syntactic structure. V - NP were interpreted as verb-object. Passives lacking a preposition were interpreted as actives. Competence in passives may be at a high level before performance is…

From the standpoint of transformational grammar, this experimental work evaluates the extent to which children choose or fail to generalize their rules for the placement of the negative particles "not" and "n't." The subjects were eight three- and four-year-olds of middle-class background who had been producing sentences with…
