1. COGNITIVE DEVELOPMENT

2. JEAN PIAGET Studied the intelligence of children
Noticed that all children gave certain wrong answers to questions and noticed a pattern
Theorized that humans organized information in two ways:
Assimilation: placing new information into existing categories
Accommodation: adjusting and creating categories for information that do not fit existing categories

3. PIAGETS STAGES OF COGNITIVE DEVELOPMENT
Sensorimotor: (0-24 mos.) stage where infants understand the world through sensation and motor activity (ex. Cause-effect relationships, shaking rattle and sound, striking mobile and movement)
Object permanence: the idea that objects still exist even if you cannot see them (peek-a-boo, hiding object behind the back)

5. Preoperational stage: (2-6 years) use of words and symbols to represent objects, can only see one perspective of a situation at a time
Conservation: properties such as weight, volume and number remain the same even if the shape changes
Egocentrism: inability to see the point of view of another (thinks everyone has the same view as he does)

6. Animism: the belief that objects are alive and conscious
Artificialistic: natural events are the doings of people
