The three views of cognitive changes that occur in early childhood. - Piaget preoperational stage of development - This stage begins from 2 years of age and last about 7 years. - In this stage, children cannot yet perform mental operation (such as reversible mental activities), but they may start to describe the environment using word, pictures, and drawing, establish persistent conceptions, and reasoning. - Limitation: Animism and egocentrism - Children of this stage attribute life-like qualities to the non-living beings such as toy, teddy. - Egocentrism is the inability to understand other’s point of view. - Kids start to think and barrage adults with inquiries during the intuitive thought sub stage, which lasts from 4 to 7 years of age. Thought during this sub stage is referred to as intuitive because kids appear to be certain of their understanding while being ignorant of how they understand what they know. - Centration and lack of conservation are the key characteristics of this stage.
