Two transitional phases in the child's early language development are described; the first occurs between prelinguistic vocalization and one-word speech and the second between one-word and patterned speech. Cognitive, linguistic and affective inputs to the acquisition of reference and syntax are discussed in the light of the transitional…

In order to test the hypothesis that the ability to form verbal concepts would increase with age, a test for verbal concept formation was developed and administered to 668 children between the ages of 4 and 9. By varying sentences that describe nonsense figures, 4 variables were systematically explored. (MS)

Recent attempts to classify the meanings of two-word utterances expressed by young children have assumed that children always intend one of the meanings adults might express. This paper challenges that assumption and suggests an alternative approach to determining the meaning of these utterances. (Author/RM)

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

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…

This paper describes part of a larger study dealing with syntax and semantics of the child's early speech about motion and location. It suggests that goal, defined as the point at which a motion ends and a resulting locative state begins, is the organizing principle for the semantics of motion and location. The data presented here are from two…

In any successful conversation, a speaker must select both what is said and how it is said on the basis of various estimates of the listener's abilities, knowledge and interests. Most research on linguistic input to children has focused on the tendency of speakers to simplify their speech for the younger listener. Little attention has been paid to…
