Cognitive Development/children/Piaget: (Piaget called his research “genetic epistemology”) Thesis: children progress systematically through a series of “stages” with distinct features and capacities:
1. Sensorimotor period (birth to two years). Infants’ understanding of the world derives from their physical actions. Their capacity to interact with the world goes from simple reflexes through several steps to an organized set of behaviors.
2. Preoperational period (two to seven years). Children begin to use symbols (mental images, words, gestures) to represent objects and events, and they are able to use symbols in an increasingly organized and logical fashion.

3. Concrete operational period (7 to 11 years). Children acquire certain logical structures that allow them to perform various mental operations, which are internalized actions that can be reversed.
4. Formal operational period (roughly 11 to 15 years). Mental operations are no longer limited to concrete objects; they can be applied to different abstract and formal representations of the physical world, such as verbal or logical statements. In addition, children can reason about the future as well as the present.
