Findings from studies exploring role of joint attentional focus in children's acquisition of language indicated that language of 24 mothers and their 15- to 21-month-olds inside episodes of joint attentional focus involved more utterances, shorter sentences, more comments, and longer conversations than outside of episodes. Also, object references…

Results from these two studies show that fast mapping--gaining information about a word from how it is used in a sentence, what words it is contrasted with, and other factors--can be used successfully by children two to four years old to form quick and rough hypotheses about the meaning of a word.

Abilities of 2-, 5-, and 7-year-old children to interpret, judge acceptability of, and produce class extensions were assessed. It was concluded that increasing ability to deal appropriately with class extensions is primarily due to general advances in language acquisition rather than to any development unique to the class-extension word-formation…

In two experiments 96 children and eight adults were tested for comprehension of the modifier-head relation in compounds such as apple-knife or were asked to label objects with compounds. Results show that by age three children reliably interpret novel compounds and made use of novel compounds to subcategorize. (RH)

Examines how reference points for the categorical interpretation of high and low (adjectives) were defined by three- to five-year-old children and adults. Shows categorical interpretations of relative terms to be complex dependent. (HOD)

English- and Japanese-speaking children aged four and five were asked to say the opposite of statements. Statements varied in truth value and unmarked/marked membership of antonym pairs. Findings did not support a universality hypothesis; differences were found between the two groups in the use of semantic and syntactic denial. (Author/CB)

Reveals that young children acquiring Mandarin Chinese differentiate subject from topic, even though Chinese is a "topic-prominent" language. Data are based on results of a standardized, elicited imitation test of 95 Chinese children in Taiwan. Subjects between 2 years, 6 months and 5 years of age responded to coordinate as well as…

Three types of metalinguistic awareness and their relation to socioeconomic status, vocabulary, reading readiness skills, and reading acheivement were longitudinally studied in a sample of 40 kindergartners and 43 first graders. The three metalinguistic tasks were highly interrelated until the effects of oral language comprehension or vocabulary…

Investigates the metalinguistic ability of monolingual or bilingual children between five and nine years of age on two language tasks (grammaticality judgment and correction). (HOD)
