Document Summary

By the time children enter the preschool years, an extraordinary amount of cognitive development has taken place. From infancy to adulthood our cognitive structures change through 4 different stages: Preoperational stage- in piagetian theory, the stage of cognitive development during which children use symbols to represent objects and events: according to jean piaget"s theory, most preschools have made the transition from sensorimotor thinking to preoperational thinking. The preoperational stage, which spans ages 2 to 7, is marked by the child"s use of symbols to represent objects and events. Due to centration, they are overlooking other parts of the problem that would tell them the quantity is unchanged. In other conservation problems, preoperational children also tend to focus on only one aspect of the problem. In conservation of number, for example, preoperational children concentrate on the fact that, after the transformation, one row of objects appears longer than the other.
