Document Summary

A research design in which the same individuals are followed over time and their development is repeatedly assessed: cross-sectional research. A research design that compares groups of people who differ in age but are similar in other important characteristics: cohort. A group defined by the shared ages of its members. Cohort effects are said to occur because the differences between groups of people may not be due to age, but to a common historical even which affected all of the people at that age. This effect can compromise cross-sectional designs: cross sequential research.
