Urie Bronfenbrenner and Ernest Boyer argued for leaving the laboratory to conduct rigorous developmental research in the real world where children are found--in the places they go. Contributions to this special issue meet Bronfenbrenner and Boyer's call while at the same time recognizing the continued importance of laboratory research. These…

An essential part of understanding number words (e.g., "eight") is understanding that all number words refer to the dimension of experience we call numerosity. Knowledge of this general principle may be separable from knowledge of individual number word meanings. That is, children may learn the meanings of at least a few individual number words…

The cross-overs between monolingual-bilingual and typically atypically developing children are a goldmine for research on language development. The four permutations of language exposure and language abilities create "natural experimental conditions" for investigating the nature of the language capacity and how this is shaped by input in typical…

During the late 1970s and 1980s, as interest in Lev Vygotsky's work was growing rapidly, most of his writings were unavailable in English. Translations of Vygotsky's work that reflect the breadth and depth of his thinking became available in the mid-to late 1990s. However, this work has yet to become an integral part of educational psychology.…

Developmental robotics has forwarded a range of models of development and behaviours. With the variety of systems that have been created, and with some of these approximating prominent human behaviours (e.g. joint attention, word learning, imitation), one may argue that developmental robotics has started to go past robotic models of earwigs…

This paper seeks to foster a discussion on whether experiments with robots can inform theory in infant motor development and specifically (1) how the interactions among the parts of a system, including the nervous and musculoskeletal systems and the forces acting on the body, induce organizational changes in the whole, and (2) how exploratory…

Two experiments explored whether children's correct answers to counter factual and future hypothetical questions were based on an understanding of possibilities. Children played a game in which a toy mouse could run down either 1 of 2 slides. Children found it difficult to mark physically both possible outcomes, compared to reporting a single…

Discusses the importance of science education in early childhood education and describes different approaches in incorporating physics into the preschool curriculum. Provides examples of experiments and encourages parent participation in children's science activities. Concludes by looking at science as an equity issue and emphasizes that science…

The National Institute of Child Health and Human Development (NICHD) Study of Early Child Care is an ongoing, prospective, 3-year longitudinal study of over 1,300 full-term healthy infants and families from 10 sites across the United States. While the sample is not nationally representative, the subjects come from major regions of the country: the…
