What are the stages (periods) of Piaget's Cognitive Development Theory?
- Sensorimotor (B-2)
- Characteristics: Infants use senses & motor abilities to understand the world. Learning is active; No conceptual or reflective thought.
- Gains: Infants Learn that an object still exists when it is out of sight (object permanence) and begin to think through mental actions
- Preoperational (2-6)Characteristic: Children think magically & poetically, using language to undersatnd the the world. Thinking is egocentric, causing children to perceive the world from their own perspective
- Gains: The imagination flourishes, and language becomes a significeant means of self-expression and of infuence from others.
- Concrete Operational (6-11)
- Characteristics: Children understand and apply logical operations, or principles, to interpret experiences objectively and rationally. Their thinking is limited to what they can personally see, hear, touch, and experience.
- Gains: By applying logical abilities, children learn to understand concepts of conservation, number, claassification, and many other scientific ideas
- Formal Operational (12-Adult)
- Characteristics: Adolescents and Adults think about abstractions and hypothetical concepts and reason analytically, not just emotionally. They can be logical about things they have never experienced.
- Gains: Ethics, politics, and social and moral issues become fascinating as adolescents an adults take a broader and more theorical approach to experience.

- Operant Conditioning - The learning process by which a particular action is followed by something desired (which makes the person or animal more likely to repeat the action)
- or by something unwanted (which makes the action less likely to be repeated)
