Cognitive development

Piaget proposed there are four stages during the children’s cognitive development. Kids will get different cognitive abilities in these stages, every stage is very important for specific cognition. If they lost that chance and didn’t get any cognition in the key stage, it will be very hard or impossible to get those kinds of cognitions back. Parents should notice that their children have entered into learning period before they go to school. In that time, they play a very important role for children's learning and cognitive development. It is very necessary for parents to learn how to develop  better cognition of their own kids.
