Document Summary
Developmental psychology: is the study of human physical, cognitive, social, and behavioural characteristics across the lifespan. Methods for measuring developmental trends : figure 10. 1. A 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 say, groups of 1-, 5-, 10-, and 20-year-olds. With this type of study, you would select a sample of infants and measure their cognitive development periodically over the course of 20 years. A longitudinal study fixes the problem of cohort effects, but the demands of following a single group of people for a long period of time can be very costly and time-consuming. A sensitive period is a window of time during which exposure to a specific type of environmental stimulation is needed for normal development of a specific ability.
