Three experiments investigated (1) whether developmental differences in the information integration rule apply to ulterior motive information; (2) whether such developmental differences are limited to situations involving parental reward; and (3) how related age differences among children can best be explained.

Micronesian children residing on Truk and Kosrae were examined for performance on eight conservation tasks and on one task each of centration and reversibility (generally precursors of conservation in Piaget's theory of cognitive development). A total of 75 children were tested--33 in the village of Moen, Truk, and 42 in all the villages of…

The purpose of this research was to examine 18- to 30-month-old children's use of scripts for representing common events. A script is defined as a model that specifies the roles and props appropriate to an event and identifies a sequence of acts for achieving the goal defined by the event. Two aspects of script knowledge were investigated: (1) the…

Discusses five- and six-year-old children's conceptions of life and death. Children were questioned about animals, plants, and inanimate objects. The most errors occurred when children judged inanimate objects; the fewest when they judged animals. The order of questions about either life or death significantly influenced children's responses.

A developmental progression in 6-, 8-, and 10-year-old children's use of strategies for gathering information was revealed in a study involving partial recall, total recall, and similarity/difference judgments. When subjects chose stimuli for exposure from an array, older children showed more ability to match strategy to task demands. Strategy…

Explores implications of two cognitive development perspectives for characterizing ontogeny of causal reasoning. Reviews literature on causal reasoning in the preschool years and concludes that the hypothesis of an invariant causal scheme is only partially correct. (Author/SO)

Delay/response inhibition in the presence of an attractive stimulus and compliance with maternal directives in a clean-up task were observed among subjects 18, 24, and 30 months of age. Results suggested (1) achievement of self-control is a major developmental accomplishment, and (2) individual differences in self-control emerge and are…

Examines extent to which knowing that certain things go together and knowing how they do are independent aspects of developing cognitive systems. Indicates that children use temporal order as organizing principle by three years of age. Suggests an earlier developmental horizon as the origin of ordering abilities. (Author/BE)

Examined two- to four-year-olds' and adults' internalized representations of the sizes of buttons, plates, and shoes in five experiments. Results suggested that three- and four-year-olds had accurate knowledge of the typical sizes of buttons and plates. Two-year-olds demonstrated accurate internal representations of the sizes of shoes.

This study investigated the role of semantic analyzability in children's understanding of idioms with 80 children (kindergarten and grades 1, 3, and 4). Idioms varied in the degree that the meanings of their parts contributed to their figurative meanings. Findings indicated age differences with younger children better understanding the…

There is increased interest by parents in communicating with their children about political violence. However, limited attention in the scholarly literature has focused on parent-child communication about war and terrorism. In response, the purpose of this study is to assess, within their respective ecological contexts, American and Northern Irish…

Few studies of person perception have examined the development of human nature concepts, i.e., the understanding of what it means to be human. In an attempt to explore the development of what being human means within the framework of cognitive development theory, 55 boys and 60 girls in kindergarten, fourth, eighth, and twelfth grade were given a…

In three experiments, children five- to 10-years-old were assessed on their comprehension of simple and compound comparatives using a picture-question answering task. Ability to use appropriate reference points increased with age on both the simple and compound comparative relations. (PCB)

Tested the hypothesis that preschool children between 2 1/2 and 6 1/2 years of age would progress though a stepwise sequence of developing ever-clearer boundaries between fantasy and reality. Findings supported the validity of the hypothesized sequence. (RH)

Demonstrates young children's shift toward a taxonomic basis for organization of both named and depicted objects. Concludes that perceptual organization in young children cannot be attributed to an inability to ignore visual information but seems to be based upon the centrality of perceptual features to the representation of objects.
