The aim of the present study was to examine how social evaluation influences creative idea generation, and whether this effect develops with age. To do so, early adolescents, middle adolescents, and late adolescents performed a creative task either alone or under the supervision of an adult examiner. Three major findings emerged: 1) the social…

Determining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990; Gil-White, 2001), whereas others point to the role of noun labels as more general promoters of kind-based reasoning…

We examined developmental changes in children's inductive inferences about biological concepts as a function of knowledge of properties and concepts. Specifically, 4- to 5-year-olds and 9- to 10-year-olds were taught either familiar or unfamiliar internal, external, or functional properties about known and unknown target animals. Children were…

The shared features that characterize the noun categories that young children learn first are a formative basis of the human category system. To investigate the potential categorical information contained in the features of early-learned nouns, we examine the graph-theoretic properties of noun-feature networks. The networks are built from the…

This paper examines the development and consistency of children's (4, 7, 10, and 14 years) naive concepts of inheritance using three tasks. A modified adoption task asked participants to distinguish between biological and social parentage in their predictions and explanations of the origins of different feature types (physical characteristics,…

Two studies (N = 456) compared the development of concepts of animal species and human gender, using a switched-at-birth reasoning task. Younger children (5- and 6-year-olds) treated animal species and human gender as equivalent; they made similar levels of category-based inferences and endorsed similar explanations for development in these 2…

Essentialism is the belief that certain characteristics (of individuals or categories) may be relatively stable, unchanging, likely to be present at birth, and biologically based. The current studies examined how different essentialist beliefs interrelate. For example, does thinking that a property is innate imply that the property cannot be…

A total of 12 three, four, five, seven, and nine year olds and 12 adult control subjects were asked 20 questions about two exemplars of each of 16 categories of animate beings and inanimate objects. Children's responses indicated that animism is not a pervasive phenomenon and does not appear to be the most primitive mode of conceptualization.…

Results of this replication study indicate considerable agreement with Piaget and Inhelder's description of stage-related verbal features while failing to confirm their description of stage-related nonverbal features. (JMB)

Piaget's conceptualization of concrete and formal operations is presented. It is contended that Piaget has obfuscated logic, metaphysics and methodology. (MS)

Concepts important to cognitive development in children can be classified according to several levels. At level 1, concepts are equivalent in structural complexity to binary relations and univariate functions. At level 2, concepts are equivalent to compositions of binary relations, binary operations, and bivariate functions. At level 3, concepts…

This article (1) discusses the progression of children's thought from realism to objectivity, to reciprocity, and to realitivity; and (2) describes seventeen types of explanations children give to explain the causality of physical occurrences in the world. (SB)

Content analysis in the manner of M. H. Nagy's 1948 study was used to explore facets of children's thoughts and feelings about death. Participants were 316 children aged 3-12 who resided in the Sydney Metropolitan Area. Subjects expressed their views on death in talking, writing, and drawing. It was found that all children progressed through three…

The purposes of this study were twofold: (1) to investigate the effect of movement for several inanimate objects on children's judgments of "aliveness;" and (2) to examine the nature of explanations given by three age groups of children in support of their judgments as to whether animate and inanimate objects were "alive" or…

This article reports on a pilot study on the development of historical understanding of elementary school children. Historical fiction was shared with second, fourth, and sixth grade children who retold the story and answered questions. Results are evaluated and suggestions for history instruction at the elementary level are discussed. (Author/MT)
