Two-year-olds use the sentence structures verbs appear in--"subcategorization frames"--to guide verb learning. This is syntactic bootstrapping. This study probed the developmental origins of this ability. The structure-mapping account proposes that children begin with a bias toward one-to-one mapping between nouns in sentences and participant…

In 2 experiments, 15- and 21-month-old infants were presented with a target object and asked to select an object taxonomically or thematically related to the target object. The target object was introduced with or without a novel nonsense noun. Results indicated that novel nouns focused infants' attention on taxonomic relations. (MDM)

In two experiments 96 children and eight adults were tested for comprehension of the modifier-head relation in compounds such as apple-knife or were asked to label objects with compounds. Results show that by age three children reliably interpret novel compounds and made use of novel compounds to subcategorize. (RH)

Examines how reference points for the categorical interpretation of high and low (adjectives) were defined by three- to five-year-old children and adults. Shows categorical interpretations of relative terms to be complex dependent. (HOD)

In a series of five experiments, young children (two- and three-year-olds) were presented with novel objects in which perceptual and functional features varied independently. Results indicate that early conceptualizations and word meanings are perceptually based when perceptual and functional features are independently available. (Author/RH)

Three experiments tested 3-year-olds' subordinate classification. The first experiment found that novel noun presentation hindered classification. The second and third experiments found that provision of information for the purpose of distinguishing relevant subclasses, and introduction of novel nouns in conjunction with familiar basic level…

Examined the use by children of the Novel Name-Nameless Category principle, under the framework that lexical principles are acquired in a developmental sequence. Results indicated that the particular principle was not available at the start of lexical acquisition but that exhaustive categorization ability and a vocabulary spurt occur…
