The purpose of the current microgenetic study was to examine children's spontaneous application of analogical problem solving from story problems to physical tasks. Thirty-six 4-year-olds (M=54.7 months), randomly assigned to an experimental or a control condition, participated. The results indicate that 4-year-old children did, with varying success, spontaneously apply analogical solutions to physical problems across sessions. A positive effect over time on children's spontaneous analogical problem solving was found. Additionally, a few children even gave an analogical strategy-related explanation for their own physical behavior. There was much inter- and intra-individual variability, which may indicate that 4 years of age is a period of change in the development of analogical reasoning.

Half a century of dedicated field research has brought us from ignorance of our closest relatives to the discovery that chimpanzee communities resemble human cultures in possessing suites of local traditions that uniquely identify them. The collaborative effort required to establish this picture parallels the one set up to sequence the chimpanzee genome, and has revealed a complex social inheritance system that complements the genetic picture we are now developing.
The discrepancy between children's performances on Brown and Murphy's (1975) and Piaget and Inhelder's (1956) studies of ordering tasks was investigated. Twenty-two 4-year-old children were asked to carry out a linear-ordering task that was based on Piaget and Inhelder's (1956) task in which children copied the arrangement of clothes on a clothesline. The type of instructions and the type of layout were varied. There was an effect for the type of layout (p < .01), but the children performed equally well irrespective of the instructions they were given, and overall they were very successful. The results support Brown and Murphy's findings that ability to reproduce a sequence in linear-ordering tasks is developed earlier than previous research has indicated.
