This paper explores the process through which children sort out the relations among verbs belonging to the same semantic domain. Using a set of Chinese verbs denoting a range of action events that are labeled by carrying or holding in English as a test case, we looked at how Chinese-speaking 3-, 5-, and 7-year-olds and adults apply 13 different…

Numerous distributional cues in the child's environment may potentially assist in language learning, but what cues are useful to the child and when are these cues utilised? We propose that the most useful source of distributional cue is a flexible frame surrounding the word, where the language learner integrates information from the preceding and…

When faced with a sentence like, "Some of the toys are on the table", adults, but not preschoolers, compute a scalar implicature, taking the sentence to imply that not all the toys are on the table. This paper explores the hypothesis that children fail to compute scalar implicatures because they lack knowledge of relevant scalar alternatives to…

Many studies have established that children tend to exclude objects for which they already have a name as potential referents of novel words. In the current study we asked whether this exclusion can be triggered by social-pragmatic context alone without pre-existing words as blockers. Two-year-old children watched an adult looking at a novel…

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

Two stages in the vocabulary development of two-year-olds are reported. In the earlier Receptive stage, the child says many fewer nouns than he understands and says no verbs at all although he understands many. The child then enters a Productive stage in which he says virtually all the nouns he understands plus his first verbs. (Author/DEP)

Presents the goals of the Plunkett and Marchman (PM) connectionist model of the acquisition of verb morphology, and responds to related criticisms. Claims that small vocabulary size allows young children to correctly produce both regular and irregular past tense forms, and that non-linearities in vocabulary growth are a contributing factor to the…

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…

Examined role of isolated words in early vocabulary development. Found that isolated words are a reliable feature of speech to infants; that they include a variety of word types; and that a substantial fraction of words infants produce are words that mothers speak in isolation. Frequency of hearing words in isolation better predicts learning than…

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…
