While content words (e.g., 'dog') tend to carry meaning, function words (e.g., 'the') mainly serve syntactic purposes. Here, we ask whether 17-month old infants can use one language-universal cue to identify function word candidates: their high frequency of occurrence. In Experiment 1, infants listened to a series of short, naturally recorded…

There is growing evidence that words that are acquired early in life are processed faster and more accurately than words acquired later, even by adults. As neuropsychological and neuroimaging studies have implicated different brain networks in the processing of action verbs and concrete nouns, the present study was aimed at contrasting reaction…

Notes young children's fast mapping ability for word and fact learning. Finds children's extension of a new word to novel objects from same category but lack of extension for new facts, as replicated by Waxman and Booth, unsurprising. Poses more interesting question: is word learning done solely through more general cognitive systems or through…

Three experiments introduced 2- and 3-year-olds to novel adjectives either using full noun phrases and describing multiple familiar objects sharing a salient property or describing nouns of vague reference. Found that both groups mapped novel adjectives onto object properties when given taxonomically specific nouns with rich referential and…

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…

Two experiments examined differences in the early noun learning of English- and Japanese-speaking children. Found that English-speaking children's vocabularies were heavily lopsided with many more object than animal names, whereas Japanese-speaking children's vocabularies were more evenly balanced. Results suggested that early learners of English…
