Document Summary

We recognize now that development does not stop at the end of childhood. Growing older is a matter not only of aging, but also of changing personally, intellectually, and socially. Developmental psychologists study both the similarities and the differences among people as they develop and change. Since they study change, developmental psychologists employ special strategies of research. Cross-sectional study individuals of different ages are simultaneously compared with respect to some test or observation. Ex) a developmental psychologist might present mathematical problems to groups of five-, seven-, and nine-year-olds to measure the children"s grasp of the concept of negative numbers. In contrast, a longitudinal study compares observations of the same individuals at different times of their lives. A longitudinal study of children"s grasp of negative numbers might test a group of children when they were five years of age, and then repeat the test on the same children at seven and then at nine.
