Two studies examining children's understanding of three terms denoting different degrees of likelihood showed that, while preschoolers showed little comprehension of the adverbs' meanings, by fourth grade, most children could distinguish between them. Children understood the distinction between "definitely" and the other two terms better than the…

Investigated the hierarchical organization of the semantic system in preschoolers with and without word-finding deficits. Children named a series of objects at multiple levels of the noun hierarchy in response to contrast questions. Children with word-finding deficits had similar abilities to the other children but did not have enough stored…

Three investigations of preschool children's comprehension of "younger" and "older" are discussed. Results suggest children focus on height in their initial hypotheses about meanings of the terms, ignoring age or function cues. These and findings about acquisition of antonyms are discussed in terms of recent theorizing about lexical-meaning…

Diary observations of two-year-olds' over-extended word use have been interpreted as arising from the word's underlying semantic feature structure. This interpretation was rejected after a study of five children. The need to construct models of early word meaning reflecting certain early language development patterns is discussed. (CHK)

To explore adjective language development and examine its relationship to seriation, several tasks were given to 40 children aged 4-8. Comprehension and production of adjective forms were measured--vocabulary, coordination, comparison. Ability to order objects by size was used to assess intuitive-level seriation. (CHK)

Children aged 2 1/2-4 were asked questions containing comparative and superlative forms of adjectives in pairs designated as unmarked/marked or positive/negative. Differences in frequency of correct responses were greater between unmarked/marked pairs than between positive/negative pairs. No evidence appeared for a marking explanation of adjective…
