We examined whether the distinction between generic and nongeneric language provides toddlers with a rapid and efficient means to learn about kinds. In Experiment 1, we examined 30-month-olds' willingness to extend atypical properties to members of an unfamiliar category when the properties were introduced in 1 of 3 ways: (a) using a generic noun…

Generic noun phrases, or generics, refer to abstract categories ("Dogs" bark) rather than particular individuals ("Those dogs" bark). Study 1 investigated how parents use gestures in association with generic versus particular reference during naturalistic interactions with their 2- and 3-year-old children. Parents provided…

These studies investigated two hundred and forty-four 24- and 30-month-olds' sensitivity to generic versus nongeneric language when acquiring knowledge about novel kinds. Toddlers were administered an inductive inference task, during which they heard a generic noun phrase (e.g., "Blicks drink milk") or a nongeneric noun phrase (e.g., "This blick…

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;…

English-speaking children understand and produce generic expressions in the preschool years, but there are cross-linguistic differences in how generics are expressed. Three studies examined interpretation of generic noun phrases in three- to seven-year-old child (N=192) and adult speakers (N=163) of Mandarin Chinese. Contrary to suggestions by…

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants' generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to…

Prior research indicates that category labels influence category judgments, but little is known regarding the effects for familiar categories with significant social consequences. The present studies address this issue by examining the effect of linguistic form on judgments of illnesses. Both mental and physical illnesses were presented in each of…

Generic noun phrases ("Birds lay eggs") are important for expressing knowledge about abstract kinds. The authors hypothesized that genericity would be part of gist memory, such that young children would appropriately recall whether sentences were presented as generic or specific. In 4 experiments, preschoolers and college students (N = 280) heard…

Generic sentences (such as "Birds lay eggs") are important in that they refer to kinds (e.g., birds as a group) rather than individuals (e.g., the birds in the henhouse). The present set of studies examined aspects of how generic nouns are understood by English speakers. Adults and children (4- and 5-year-olds) were presented with scenarios about…

Investigates the ability of 32 two-year-old children to use syntactic (i.e., form class) and semantic (i.e., type of referent) information to interpret the meaning of new nouns. Subjects were taught either a common noun or a proper noun for a block-like or animal-like object and then asked to select the named toy. (Author/CB)

Two studies used a comprehension task and an elicited production task to examine whether preschool children and adults appreciated the semantic properties of generic utterances. Findings indicated that in both tasks, 4-year-olds and adults treated generics ("bears live in caves") as distinct from both indefinites ("some") and universal quantifiers…

Two strategies that children use to figure out new word meanings--attention to linguistic form class and the assumption of lexical contrast--were examined. It was found that very young children use both form class and lexical contrast to interpret new words. (PCB)

Children performed well on tasks involving pictures regardless of whether the pictures were named. Performance on atypical pictures was better when category labels were provided than when labels were not provided. A control study demonstrated that children ignored labels when they named a transient, as opposed to a stable, category. (RH)

Discusses two studies that examine whether children are sensitive to the fact that adjectives and nouns differ in the contrast they imply. Results show that by age four, children are sensitive to this. Implications for children's use of referential language and word learning strategies are discussed. (SED)

Compared the proportions of nouns and verbs in early vocabularies of English- and Mandarin-speaking toddlers and their mothers. Found that Mandarin-speaking children had relatively fewer nouns and more verbs than English-speaking children. When reading books, children's vocabularies were dominated by nouns but not when playing with toys. Mothers…
