The goal of the present study was to explore domain differences in young children's expectations about the structure of animal and artifact categories. We examined 5-year-olds' and adults' use of category-referring generic noun phrases (e.g., "Birds fly") about novel animals and artifacts. The same stimuli served as both animals and artifacts;…

Errors differ in degree of seriousness. We asked whether preschoolers would use the magnitude of an informant's errors to decide if that informant would be a good source of information later. Four- and 5-year-olds observed two informants incorrectly label familiar objects, but one informant's errors were closer to the correct answer than the…

Grammatical gender is generally considered an early and error-free acquisition in French children. This article first examines how children cope with the gender attribution problem, "i.e.", how they determine the gender of individual nouns. We consider the plausibility and requirements of an account in which tacit phonological assignment rules are…

Can 6- and 8-year-olds (and adults) comprehend common instrument verbs when extended to novel situations? Participants heard eight unusual extensions of common verbs and were asked to paraphrase the verbs' meanings. Half of the verbs used were "specified instrument" verbs that include the name of the instrument used to perform the action (e.g., a…

In the course of language development children must solve arbitrary form-to-meaning mappings, in which semantic components are encoded onto linguistic labels. Because sign languages describe motion and location of entities through iconic movements and placement of the hands in space, child signers may find spatial semantics-to-language mapping…

This paper examines the effects of the playworld educational practice on the development of narrative competence in 5- to 7-year-old children. The playworld educational practice is derived from play pedagogy and the theory of narrative learning, both developed and implemented in Scandinavia. The playworld practice consists of joint adult-child…

Four experiments used a free-naming task to examine four-year olds' and adults' default construals of solids and nonsolids. Found that children named an individual-related word (such as shape) for solid materials, but gave a substance-related name for nonsolids. Results suggest that children conceptualize solids and nonsolids in distinct,…

Used a framework-isolating analysis of knowledge and control of processing components to investigate preschoolers' acquisition of cardinality. Found that cardinality emerges gradually in children between ages three and five. Also, tasks that increase the processing burden of a basic counting problem by adding demands for either analysis or control…

In many cognitive domains, learning is more effective when exemplars are distributed over a number of sessions than when they are all presented within one session. The present study investigated this "distributed learning effect" with respect to English-speaking children's acquisition of a complex grammatical construction. Forty-eight children…

Examined thematic and grammatical role categories accessible to preschool children and how access to these categories changes with age. Results of three experiments with children and adults confirmed the psychological reality of certain semantic categories, and provided evidence suggesting a transition in the prominence of semantic relative to…

Study 1 explored associations between multiple measures of language and symbolic gesture development across ages 3 and 4; Study 2 measured more finely which aspects of language relate to the symbolic representation of actions with objects, and explored associations between symbolic gesture and general intellectual ability. Results showed…

Study of 3 and 7 year olds and adults examined role that changes in continuity, direction, instrument, and causative agent play in children's and adults' initial assumptions about meaning of novel motion verbs and events. Subjects made similar initial assumptions, but children generalized more conservatively than adults to all change types in…

A study with three- and five-year olds contrasted two important proposals regarding children's assumptions about word meanings: the taxonomic assumption proposal and the shape bias proposal. Results suggest that perceptual similarity, particularly shape similarity, is very important in early word meaning but that children gradually shift their…

Children ages five, seven, and nine years named objects with multiple names in a neutral context and in a biased context. Children selected names in accord with nonlinguistic constraints, but at the cost of longer naming times. Both name selection success and associated cost were more evident in older children than in younger children. (TJQ)

This research investigates preschoolers' use of desires for word learning. Three-year-old children were shown pairs of novel toys and were asked about their own desire and told about a researcher's desire. For half of the children the researcher liked the same object they did and for the other half the researcher liked a different object. The…
