Document Summary
Module 10. 1: physical development from conception through infancy. Development psychology is the study of human physical cognitive, social and behavioural characteristics across the lifespan. A cross-sectional design is used to measure and compare samples of people at different ages at a given point in time. In contrast, a longitudinal design follows the development of the same set of individuals through time. Longitudinal study fixes the problem of cohort effects but the demands of following a single group of people for a long period can be very costly and time consuming. Longitudinal designs suffer from the problem of attrition, where participants drop out of a study for reasons like losing interest or moving away. Development is seen as a progression of abrupt transitions in physical or mental skills, interspersed with slower more gradual change. Psychologists describe this pattern of change as a series of stages. Complex interactions between genetics and the environment are constantly shaping developmental processes.
