Jean Piaget's Stages Of Cognitive Development Among Children

Jean Piaget had many studies relating to how the mind worked with objects and how the brain developed. He came up with stages of cognition development that was and still can be considered how the mind cognitively develops among children. Piaget wanted to test an idea that while the child is developing, they have no idea of object permanence until a certain stage and cannot move on from the first stage until object permanence is developed. Piaget tested this idea using his own three children. Jacqueline was born in 1925, Lucienne in 1927 and Laurent, born in 1931 were Piaget’s test subjects. Piaget studied his own children by observing them naturally how they were raised to test object permanence.
Piaget’s hypothesis was that children must develop object permanence before leaving the Sensori-motor stage of development. He wanted to see at what age this occurred and how it developed differently among different children. The idea of object permanence is simple, knowing the object exists even when not in view. Piaget explains this idea is remarkably important because a person cannot problem solve and internally think without object permanence. Piaget expected to find that his own three children would eventually have the idea of object permanence, however, Piaget wanted to know when this would happen.
The participants of the study conducted were Piaget’s own children, Jacqueline, Lucienne, and Laurent. They were the ages of 0-2 while they were being studied for object permanence but were still observed after for

However, the object permanence itself has been shown through other studies and is believed widely. Another critique that was widely known was that the stage can differ from child to child. However, there is not a different way the study could be studied because a child must be studies or observed in order the find results to object
