Assesses three papers in this volume, those by Wellman and Estes, Olson and Torrance, and Hall and Nagy, for their treatment of the following: (1) definition of semantic space, (2) defining children's processes of understanding that space, and (3) describing the contexts in which cognitive language is used. (AEW)

Compares semantic uses of mental state words by children four and a half to five years old. Suggests that children's linguistic and cognitive capacities can be influenced a great deal by subtle situational factors and that the effects vary according to the child's cultural background. (AEW)

Examines the quality of conversation produced by small groups of subjects in fifth, ninth, and twelfth grades and the last year of college. Results supported Piaget's sequence of conversational development. However, topical coherence apparently is not fostered by focused turns but emerges as a generalization of the normative constraints applying…

Critically examines papers by Wellman and Estes, Olson and Torrance, and Hall and Nagy. (AEW)

Two major strategies for linguistically encoding an idea or proposition are suggested. The first strategy involves encoding an idea in the space of a single utterance, while the second strategy conveys the proposition through a sequence of two or more utterances. The tendency has been to focus on discourse as a composite of sentences (the first…

Investigates the availability of syntactic cues to verb meaning. In Experiments 1-3, adult subjects' judgments of verbs' semantic similarity were compared with other adults' judgments about the syntactic properties of the same verbs. In Experiment 4, subjects paraphrased sentences formed by pairing verbs with unaccustomed sentence frames. (54…

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…

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…

This paper proposes a broad outline of a variable model of language development and explores several particulars of such a model in the language behavior of four two-year-old children. The process by which information about language is progressively transformed and integrated rather than merely being added together can be seen in the shifting…
