Young children's skilled generalization of newly learned nouns to new instances has become the battleground for two very different approaches to cognition. This debate is a proxy for a larger dispute in cognitive science and cognitive development: cognition as rule-like amodal propositions, on the one hand, or as embodied, modal, and dynamic…

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…

Showed English- and Japanese-speaking 3-year-olds novel objects named with either known nouns referring to items similar in shape or material and color, or novel nouns. Found that with known nouns, children attended to shape when names referred to a shape-organized category, but not when names referred to a category organized by other properties.…

This paper reports evidence from a longitudinal study in which children's attention to shape in a laboratory task of artificial noun learning was correlated with a rate shift in noun acquisitions. Eight children were tested in the laboratory at 3-week intervals beginning when they had less than 25 nouns in their productive vocabulary (M age=17…

In the novel noun generalization task, 2 1/2-year-old children display generalized expectations about how solid and nonsolid things are named, extending names for never-before-encountered solids by shape and for never-before-encountered nonsolids by material. This distinction between solids and nonsolids has been interpreted in terms of an…

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…

Proposes an alternative account of the child's learning of nouns and adjectives that relies on properties of the semantic categories to be learned and of the word-learning task itself. In five experiments, a simple connectionist network was trained to label input objects in particular contexts; the network learned categories resembling nouns…
