- The sensorimotor stage: 0-2, is focused
- on coordinating the activities of the senses with motor activities.
The preoperational stage: 2-7, is when children become capable of symbolic thinking, such as the use of language, or using a broom to represent a horse.
The concrete operations stage: 7-11, children focus on what can be experienced and manipulated in the environment. His example for this stage is that you can take a glass of water, pour it into a taller, thinner glass, and kids at this age will understand that the amount of water didn't change.
- The formal operations stage begins at age 11 and lasts until about age 15 or 20. At
- this age, children can use logical and systematic thinking, use reasoning, and
- think scientifically. He called this hypothetical-deductive reasoning. Other
- types of thinking also emerge at this stage– abstract thinking, ability to use
- metaphors, and ability to use sarcasm.
