List Piaget's Stages of Development.
1. Sensorimotor
2. Preoperational period
3. Concrete operational
4. Formal operational
23
What occurs during Piaget's Sensorimotor Stage?
1. object permanence- the understanding that an object still exists, even though it can’t be seen
2. coordination of sensory input and motor responses; development of object permanence
24
What occurs during Piaget's Preoperational stage?
1. Centration- the tendency to focus on just one feature of a problem
2. Irreversibility- the inability to envision reversing an action
3. Egocentrism – limited ability to share another’s view point
25
What occurs during Piaget's Concrete operational stage?
1. Decentration – the ability to focus on more than just one feature of a problem
2. Begin mastery of concrete operations, but struggle with hierarchical classification
3. mental operations applied to concrete events; mastery of conversation, hierarchical classification
4. Decline in egocentrism
