Two experiments used the preferential looking task to assess early word comprehension in 12- to 24-month olds. Results indicated that when target stimuli were named, 12-month olds displayed an increase in target looking for typical--but not atypical--targets, whereas 18- and 24-month olds displayed increases for both.

Reports on two studies that examined the natural process of word learning in children 4-11 years old. The children hear the new words in a conversation, a story, and paired with a definition. Results indicate that children at all ages could acquire a partial semantic representation from a single exposure. (SED)

People of ages 4, 6, 8, 10, 20 and 70 years named pictures selected to represent the entire range of lexical consensus among 20-year-olds. Consensus within each group increased with age, up to 20. Data indicate words coding culturally important events are acquired earliest. (CHK)

Data from 48 infants revealed (1) that infants aged 1;2-2;3 failed to establish a stable word-object link even in follow-in labeling and (2) that only infants aged 1;6-1;7 could identify the correct referent during discrepant labeling. During the period between 1;2-1;7 infants are becoming increasingly adept at acquiring new labels under minimal…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

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)

Examines children's variation in rate, style, and sequence of grammatical development, within and across natural languages. Using a sample of English and Italian infants, concludes that while there are structural differences between English and Italian that could affect the order in which nouns and verbs are acquired, no differences were observed…

The paper examines the nominal lexicon in later language acquisition as a window on linguistic knowledge and usage across childhood and adolescence. The paper presents a psycholinguistically motivated and cognitively grounded analysis of the distribution of ten semantic noun categories (the Noun Scale) across development, modality, and genre.…
