The labels used to describe patterns and relations can influence children's relational reasoning. In this study, 62 preschoolers (M[subscript age] = 4.4 years) solved and described eight pattern abstraction problems (i.e., recreated the relation in a model pattern using novel materials). Some children were exposed to concrete labels (e.g.,…

Two experiments examined the possibility that children and adults possess a single-object/single-motion intuition. This intuition involves the view that all parts of a rigid object must move at the same speed because they all move together. (RH)

Compensation as assessed by any one test or criterion used is more difficult than conservation. And, the understanding of the compensation principle, as manifested in verbal statements, continues to develop well after the age at which liquid conservation may be taken for granted. (Authors)

Examines research in folkbiology (commonsense understandings of plants and animals) to argue that several lines of comparative research are needed to understand the acquisition of folkbiology in particular and conceptual development in general. Asserts that comparisons are needed between children and adults within a given society, between adult…

A sample of 838 children ages 5 through 15 years in Australia, England, North America, and Sweden were interviewed about physical and sexual development. The study covers essentially the same area as Bernstein and Cowan (1975) but extends the sample on the dimensions of age, number, randomness, and comparisons made. (Author/RH)

Examined effectiveness of conflict resolution training integrated into a curriculum unit on friendship taught daily for 4 consecutive weeks to kindergartners in a midwestern suburban school. Found significant differences in trained and untrained children's knowledge and retention of the conflict resolution procedure, willingness and ability to use…

Evaluates the growth of social-cognitive knowledge in deaf and hearing children during the early- and middle-school years and assesses the relative importance of language in two domains of social cognition. In addition, separately examines the child's ability to evaluate the concepts of good and bad and to take another person's perspective. (RH)

Two studies explored how mothers and preschoolers talk and reason about events in which biological and nonbiological objects change in size. Analysis of conversations indicated that although mothers discussed events primarily in domain-specific ways when using the term growth, they exhibited some domain blurring in explanations to preschoolers.…

Examined role of social-referential context in 13- and 18- month-olds' mapping of verbal and nonverbal symbols to object categories. Found that infants at both ages showed evidence of learning both words and sounds when the experimenter produced a label within a familiar naming routine, and failed to learn when labels were emitted from a baby…

Used cases of democratic and non-democratic governmental systems and freedom of speech to investigate 6- to 11-year-olds' notions of political fairness and democracy. Found that political fairness concepts were applied at all ages to evaluate governmental systems and reject non-democratic alternatives. Older children were more likely than younger…

Examined in 2 studies development and consequences of 6- to 10-year-olds' awareness of others' stereotypes. Findings indicated that children's ability to infer an individual's stereotype and awareness of broadly-held stereotypes increased with age. Academically stigmatized groups (African American and Latino) were more likely to be aware of…
