Ambridge argues that there is widespread agreement among child language researchers that learners store linguistic abstractions. In this commentary the authors first argue that this assumption is incorrect; anti-representationalist/exemplar views are pervasive in theories of child language. Next, the authors outline what has been learned from this…

Language exerts a powerful influence on our concepts. We review evidence documenting the developmental origins of a precocious link between language and object categories in very young infants. This collection of studies documents a cascading process in which early links between language and cognition provide the foundation for later, more precise…

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…

There are numerous models of how speech segmentation may proceed in infants acquiring their first language. We present a framework for considering the relative merits and limitations of these various approaches. We then present a model of speech segmentation that aims to reveal important sources of information for speech segmentation, and to…

Describes a study that examines the pragmatic language functions used by school-age children during a structured dialog consisting of a question-answer paradigm. Develops a 10-category taxonomy to classify subjects' responses and finds the taxonomy to be effective in two ways: (1) the number of categories is sufficient, and (2) the interscorer…

Three experiments examined the ability of 60 3-year-old children's ability to select homonym pairs and the extent to which they realized that homonyms represent 2 different categories. Results confirm that children have the metalinguistic skills necessary to identify homonym pairs and to realize they represent two different categories, suggesting…

Three experiments investigated the processes by which 2-year-olds acquire the language to express category hierarchies. The first experiment studied how children use current linguistic knowledge to constrain the potential meanings of new words. This experiment compared interpretations of new words given to objects the children could already name…

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)

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations.

On the basis of an analysis of several earlier classifications of language functions a three-dimensional classification is presented. It interprets the utterance in question in terms of 1) the speaker's intended influence on the listener, 2) the speaker's intentions and attitudes, and 3) the speaker's intentions with respect to the content of the…

The categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basic category cuts are made. Basic categories are those which carry the most information, possess the highest category cue validity, and are, thus, the most…

A study investigated Japanese children's acquisition of the syntactical subcategorization of action verbs. Aspects of caregiver language that provide children with information about the characteristics of an action verb are detailed, and the utterances of four Japanese toddlers are analyzed for their usage characteristics. Caregiver sentences are…

Six children were studied from the age of 6 months to 1 year and 6 months to chart their developing comprehension vocabularies from the first to the 100th word. Observational data were used in the first instance to identify newly comprehended words and then controlled testing was carried out for each word to confirm and expand the observational…

Children aged three to five were the subjects of two studies of the development of ability to classify diverse objects into superordinate categories. In the first experiment, subjects were asked to designate two of three pictorially represented objects as representative of a given category. The second experiment required subjects to choose from a…

This paper examines the validity of diagnostic categories frequently used to classify children with severe language disorders by determining the relationship of the categories to independently derived developmental, psychological, and medical variables. It is argued that the classification systems currently available too often fail to achieve the…
