Introduction for “Piaget †Stages of cognitive development” Essay

Swiss Psychologist Jean Piaget (1896-1980) proposed the idea of the four stages of childhood cognitive development. These are age-related stages and refer to authentic accomplishments that should be achieved, by the child, at the end of each stage.The first stage of cognitive development is the sensorimotor stage, which lasts from birth to around two eld of age. During this stage, children learn to coordinate their senses (hearing, sight, touch etc.) with their motor abilities. From two to seven-spot years is the Pre- useable stage. Children of this age become capable of more sophisticated thinking. The cover operational stage lasts from almost seven years of age to about twelve. These children put together what they let already learnt, with knowledge gained from untested experiences. The final stage of cognitive development identified by Piaget, is the Formal operational stage. This lasts from twelve years of age onwards. People in this stage are capable of more complex thoug ht processes.During the Concrete operational stage (7 to 12 years), children should develop an substantiateing of the principle of preservation. Conservation refers to the idea that if an object alters its effect or appearance, its volume, mass, length or area will not change. A child with an understanding of conservation should be able to think logically and see that these qualities have not changed, even if they appear to have done so. Achievement of conservation of mass can be demonstrated with two small balls of plasticine. A child is shown the plasticine and agrees that the balls are the same size. One of the balls is then squashed down. A pre-concrete operational child will probably decide that the squashed ball is bigger, while a child at the Concrete operational stage should acknowledge that they are still the same weight or mass. This illustrates the ability of the child to understand how the object has changed, not only see the beginning and end result.
