Describe each of the four stages in Piaget’s theory.
Stage1: Sensorimotor Stage (Birth - 2 years)
The main achievement during this stage is object permanence - knowing that an object still exists, even if it is hidden.
Stage2: Preoperational Stage (2 - 7 years)
During this stage, young children can think about things symbolically. This is the ability to make one thing - a word or an object - stand for something other than itself.
Stage3: Concrete Operational Stage (7 - 11 years)
Piaget considered the concrete stage a major turning point in the child's cognitive development because it marks the beginning of logical or operational thought.
Stage4: Formal Operational Stage (11 years and over)
The formal operational stage begins at approximately age eleven and lasts into adulthood. During this time, people develop the ability to think about abstract concepts, and logically test hypotheses.
Give examples of the following and indicate the stage when each occurs:
object permanence: Sensorimotor Stage
egocentrism: Preoperational Stage
conservation: Concrete Operational Stage
abstract reasoning: Formal Operational Stage
What are some of the problems with Piaget’s theory?
(1)Because Piaget concentrated on the universal stages of cognitive development and biological maturation, he failed to consider the effect that the social setting and culture may have on cognitive development.
(2)Because Piaget conducted the observations alone the data collected are based on his own subjective interpretation of events. It would have been more reliable if Piaget conducted the observations with another researcher and compared the results afterward to check if they are similar.
