Document Summary
Piaget referred to this concept as conservation: conservation: the ability to understand that a quantity remains the same after a physical transformation, the ability to conserve develops through the third stage of cognitive development (concrete operations stage 7-11). How do we study cognitive development: observational research: children are studied in a naturalistic setting such as home or school. Example: video or audio recordings of children, checklists of behaviours and questionnaires for parents to fill in. Disadvantage: interfering factors cannot be controlled, and there may be subjective interpretation of children"s behavior by observers. Advantage: the research is quick and easy to carry out, as both groups can be tested in a short period of time. Disadvantage: we cannot discover much about the process of change. When to use: if we want to describe children at different points in time. b. longitudinal design: a research design in which the same gruop of children are tested repeatedly over a period of time.
