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…

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)

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)

The comprehension ability of 36 children at three stages of telegraphic speech was assessed using active behavioral responses to declarative and imperative sentences. A significant increase in verbal and behavioral appropriateness with age was found for imperative and declarative forms. Results are compared with Shipley, Smith and Gleitman's…

Experiments in eliciting true/false judgments from young children aged 3-5 used a "talking doll," a toy panda with a speaker installed. The procedure has been used in studies of language comprehension, communication skills, and free conversation experiments. (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…

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.…

Based on a study of 50 children between the ages of 3;0 and 5;6, the reasons for the differential difficulty of various forms of "who,""why,""when," and "how" questions are postulated. (EJS)

Examines the CDI-WORDS Short Form vocabulary checklist as an index of language production. The study focuses on the associations between this short form and directly observed measures of lexical production; the associations between short-form checklists administered at different ages; the predictive associations between short form scores and…

In order to investigate the development of word-formation abilities, 3-, 5-, and 7-year-olds were asked to act out with toys, judge, and make up sentences containing instances of class extension. Some sample sentences are "Can you upside-down the clown?" and "Broom the spoon." Children dealt with such sentences in much the same…

A study was conducted to test whether three, four, and five-year-old children would be better able to use either static or dynamic properties for grouping objects, and whether performance under these conditions would be better than when no property was given. One of the two study tasks, the free sort, also used by Rosch et al. (1976), asked…

Comprehension of the quantifiers "some" and "all" was studied with 202 children, three to nine years old. Thirty-two quantifier sentences dealing with descriptions of circles and squares were presented to the children. Wooden objects were presented to some children to see if results were affected by the choice of abstract objects, but no…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…

The recent experimental literature on the acquisition of English antonyms is reviewed, with special reference to the position of Eve Clark and the particular ontogenetic assumptions her position entails. The assumptions examined are: (1) in a hierarchically organized lexical domain, the order of acquisition appears to be from the top of the…
