Document Summary

Developmental stage: sensorimotor, preoperational, and then cognitive concrete operational development 7-12 years old. (concrete means practical) Reversibility: the ability to understand that some objects, textures, can change shape, almost infinitely. Seriation: the ability to put things in order, per quantity, length and weight. Piaget"s finding; horizontal decalage: children grasp some concepts before others, they begin to understand the conservation of number, the conservation of length and then the conservation of mass, and lastly, the conservation of liquid. Information processing: (processing information, storing it, and then use it later) at this stage, it is the result of the development of the brain. Because of the development of the brain, the brain weights a little bit more, because there has been a huge increase in myelin. It"s an increase in the information processing capacity: there is an increase/gain in the cognitive inhibition. (it is the ability to screen out unimportant information and to be able to concentrate on the present)
