Document Summary
Developmental psychology is the study of human physical, cognitive, social, and behavioural characteristics across the lifespan. Cross-sectional design is used to measure and compare samples of people at different ages at a given point in time. For example, to study cognition from infancy to adulthood, you could compare people of different age groups. Are relatively cheap and easy to administer, and they allow a study to be done quickly (because you don"t have to wait around while your participants age) Cohort effects differences between people that result from being in different time periods, such as differences in nutrition, parenting norms, medical advances, cultural changes, environmental pollutants, or many other factors. Longitudinal design follows the development of the same set of individuals through time. You typically select a sample of infants and measure their cognitive development periodically over the course of 20 years.
