Investigates the perceptual representation of speech by young infants using a modification of the high-amplitude sucking (HAS) procedure. Results demonstrate that the infants' representations preserve detailed information about both the consonantal and vocalic portions of the syllables. (Author/RWB)

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations.

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Reports on data collected in nine age ranges from 18 months to 71 months that examined children's ability to understand emotion-descriptive adjectives when used by adults and their own use of these words in productive vocabulary. (HOD)

Tests the universality hypothesis of language acquisition by asking young monolingual English and Japanese children to verify true affirmatives, false affirmatives, false negatives, and true negatives. The hypothesis was not supported in the case of Japanese-speaking children. A theory of cross-linguistic language acquisition is proposed.…

Longitudinal and cross-sectional studies of young English-, French-, and Korean-speaking children showed that, across the three languages, children go through three similar developmental stages before they acquire the adult system of answering negative questions. Several language-specific phenomena were observed. (BC)
