what are the sub-areas of cognitive skills and development according to piaget?

Question

DEFINATION OF SENSORIMOTOR SKILLS, CONCEPT DEVELOPMENT AND PREACADEMIC SKILLS

Answer 1

Probably shouldn't do your homework, but here goes:
Piaget focused his studies on how childrn use their intelligence. He proposed that children's thought processes go through 4 major stages.
Sensorimotor period (birth to age 2) Infants are developing the ability to coordinate their sensory input with their motor actions. The major development during this stage is the gradual appearance of symbolic thought. Learning what language is, for example. They also learn the concept of object permanence. Put the ball in the toybox and it still exists even though you can't see it.
Preoperational period (ages 2-7) Improved use of mental images. Following the plot of a story, for example. This stage is marked by what the child LACKS.
Conservation- if an item changes shape (pouring a fixed amount of water into different sizes of beakers) does the volume change. The child will say it does due to the flaws in thinking which include
centration- focusing on one aspect at a time rather that the whole picture.
irreversability-not comprehension of reversing an action.
egocentrism-limited or inability to share another's viewpoint.
an aspect of egocentrism is animism-all things are alive.
Concrete Operational period-children can perform operations on tangible objects and actual events. They can't answer questions that start "what would happen if.........." or questions that are tiered which requires them to focus on multiple levels such as predicting chess moves.
Formal Operational period (11 and up)-enjoyment of abstact thinking. Adolescents tend to think about justice, love and free will.
After this stage, growth is demonstrated by a change in degree rather than another stage.
