The account that word learning starts in earnest during the second year of life, when infants have mastered the disambiguation skills, has recently been challenged by evidence that infants during the first year already know many common words. The preliminary ability to rapidly map and disambiguate linguistic labels was tested in Italian-speaking…

When can children speaking Japanese, English, or Chinese map and extend novel nouns and verbs? Across 6 studies, 3- and 5-year-old children in all 3 languages map and extend novel nouns more readily than novel verbs. This finding prevails even in languages like Chinese and Japanese that are assumed to be verb-friendly languages (e.g., T. Tardif,…

Labels for toys were taught to 64 infants. In follow-in labeling, the experimenter labeled a toy at which infants were looking; in discrepant labeling, one at which they were not looking. Results revealed that infants learned follow-in labels and made no mapping errors after discrepant labeling. (BC)

The present research examined how 3- and 5-year-old Japanese children map novel nouns and verbs onto dynamic action events and generalize them to new instances. Studies 1 to 3 demonstrated that although both 3- and 5-year-olds were able to map novel nouns onto novel objects, only 5-year-olds could generalize verbs solely on the basis of the…

Assessed word-learning skills of 19 deaf/hard-of-hearing preschoolers either with novel mapping strategy to learn new words, or after minimal exposure when reference was explicitly established. Found that 11 children were able to learn words in both contexts, 5 only in the second, and 2 in neither. The latter 7 children eventually were able to…
