Introduction for “Piaget †Stages of cognitive development” Essay

Swiss Psychologist Jean Piaget (1896-1980) proposed the idea of the four stages of puerility cognitive development. These are age-related stages and refer to certain accomplishments that should be achieved, by the babe, at the end up of each stage.The first stage of cognitive development is the sensorimotor stage, which lasts from birth to around two years of age. During this stage, squirtren learn to coordinate their senses (hearing, sight, foregather etc.) with their motor abilities. From two to septenary years is the Pre- running(a) stage. Children of this age become commensurate of more sophisticated thinking. The Concrete operational stage lasts from about seven years of age to about twelve. These children put together what they have already learnt, with knowledge gained from new experiences. The final stage of cognitive development determine by Piaget, is the Formal operational stage. This lasts from twelve years of age onwards. batch in this stage are capable of more co mplex apprehension processes.During the Concrete operational stage (7 to 12 years), children should develop an understanding of the rule of preservation. Conservation refers to the idea that if an object alters its shape or appearance, its volume, caboodle, length or area will non 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, maculation a child at the Concrete operational stage should get it on 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 .
