Current and comprehensive, Formal Methods in Developmental Psychology reviews and explains the advantages and details of recent methodological advances in developmental psychology. The latest progress in the use of mathematical and computer-based tools in the formulation of theories and data analysis are discussed. Individual chapters describe different approaches to computer simulation and to mathematical modeling, as well as the use of these models in a number of substantive areas including infant vision, perception of intelligence, spatial knowledge, and memory processes. This unique contribution to the "Springer Series in Cognitive Development" allows the reader a better understanding of the many forms of modeling through explicit descriptions of the steps involved in the use of various methods.
