This study is the first to test whether receipt of a federal child care subsidy is associated with children of immigrants' school readiness skills. Using nationally representative data (n ˜ 2,900), this study estimates the associations between subsidy receipt at age 4 and kindergarten cognitive and social outcomes, for children of immigrant…

Head Start enhances school readiness during preschool, but effects diminish after children transition into kindergarten. Designed to promote sustained gains, the Research-based Developmentally Informed (REDI) Parent program (REDI-P) provided home visits before and after the kindergarten transition, giving parents evidence-based learning games,…

To what extent do children understand that biological processes fall into 1 coherent domain unified by distinct causal principles? In Experiments 1 and 2 (N = 125) kindergartners are given triads of biological and psychological processes and asked to identify which 2 members of the triad belong together. Results show that 5-year-olds correctly…

Investigates the development of map-reading skills in kindergartners and second graders. The maps were read either inside or outside the space shown on the map and they were either aligned with the space or rotated 90 or 180 degrees. (Author/RH)

Tests Piaget's assertion that the anticipation of conservation among otherwise nonconserving children is a pseudoconservation since it is limited to those lacking knowledge of covariation. Number, area, and length conservation tasks and a covariation task were given to 96 children from kindergarten through the fifth grade. (Author/SS)

Two hypotheses concerning children's treatment of "less" as a synonym of "more" were tested with 4- and 5-year-olds. It was hypothesized: (1) that the "less"-"more" distinction can be taught; and (2) that conservation is dependent on the capacity to distinguish "more" and "less". (Author/CS)

Results of two experiments on kindergarten children in Japan indicate that young children can, and often do, apply personification as an analogy to animate objects to generate a reasonable prediction. It was also found that children try to constrain the personification by using additional knowledge. (PCB)

This study examined the effects of judgment-contingent feedback and prior knowledge of 3 rules on the conservation learning of 188 kindergarten children. (Author/JMB)

Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

In a four-year longitudinal study of the development of concrete operational thought, children were administered tests assessing seriation; numeration; class inclusion; hierarchical classification; and conservation of mass, weight, and volume. Levels of seriation and numeration skills in kindergarten were powerful predictors of the acquisition of…

Piaget's class-inclusion task was revised class-inclusion tasks were administered to 64 kindergarten and 64 first-graders. Each of the revisions enhanced performance as compared with Piaget's standard procedures. These results are considered in terms of two possible interpretations. (Author/SDH)

Suggests that aspects of children's early representational drawing ability may provide evidence for feature marking in nonlinguistic symbol systems. Reports results of a study of the drawings of kindergarten, second-, and fourth-grade children. (RH)

The development of perspective taking was explored in kindergarten and second grade children using a referential communication task. (BRT)

Examines kindergartners' and second graders' knowledge of concept attribute importance and the children's use of this knowledge to categorize. (HOD)

Two experiments evaluated predictions derived from a cognitive-developmental approach to delay of gratification. In the first, kindergarten children were asked to make a choice between a small immediate and a large delayed reward. In the second, children were presented with either an objective-rational or a subjective-emotional argument…
