This paper investigates six- to nine-year-old children's acquisition of evidentiality. In two minimally different tasks we assess whether children can be made to use a particular source of information by presenting them with a specific evidential term. That is, we assess whether children have an explicit awareness of the source requirement of the…

Children aged 3, 6, 9 and 12 years were asked to name and sort 25 different drinking vessels. Results showed three stages: (1) they ove rextend the term "cup"; (2) they focus only on certain perceptual properties; (3) they show growing awareness of functional properties and hence the vagueness of the boundary.

In three experiments, a multiple habituation paradigm was used to examine the ability of 7- and 9-month-old prelinguistic infants to form a natural, basic-level object category. Findings constitute independent evidence for the existence of a linguistically relevant nonlinguistic category prior to the onset of word comprehension. (SED)

Examination of object word learning and use in beginning (vocabulary of less than 50 words) and advanced (vocabulary of more than 50 words) infant speakers indicated that both groups formed concepts, learned, and generalized words for the to-be-learned objects. Advanced speakers learned more words and concepts and engaged in broader generalization…

Describes an experiment to see whether the words "front" and "back" introduce the concept of "front-back" or whether the concept preceded the words. Results show that (1) a complex disjunctive concept of "front-back" orientation precedes any knowledge of the words; (2) linguistically, "back" is comprehended before "front"; and (3) children at an…

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…

Discusses children's acquisition of non-nominal, abstract words and argues that the use of these words parallels the child's cognitive development in trial-and-error problem solving and in development of insight. (EKN)

Preschool children were required to act out a series of two-event sequences conjoined by either "before" or "after." Performance was markedly superior for meaningfully ordered sequences than for arbitrarily ordered sequences. It is suggested that the meanings of "before" and "after" must be acquired in situations which provide contextual support.…

In retelling 20 stories, 23 nursery-school children often refused to produce sentences in which causation was stated directly, but readily retold causation-implied utterances. Other results are discussed. (Author/RM)

Examines the development of children's understanding of the difference between "want" and "need" in two different experiments. The first experiment required the children to respond verbally in choosing between the two concepts; the second required them to give an object to one of two characters who had made a request using…

Investigates the potential interaction of conceptual representations and linguistic systems during language acquisition. The study examined language-thought interactions in American, Finnish and Polish children, focusing on the conceptual and linguistic development of space and time. Findings reveal that spatial and temporal linguistic systems and…
