Sensorimotor stage is the first of the stages in piagets theory cognitive development

Sensorimotor stage is the first of the stages in piagets theory cognitive development. From birth to 2 years old. It is a fast cognitive growth stage, an infant develops an understanding of everything using their action and senses. An infant can really be egocentrism because they have no understanding of the world besides of what they think. The main development in this stage is the understanding that the objects exist. For example, if you put a toy underneath a bed and the child who has managed to find the object that is object permanence, the child knows its there finds it quickly. At first the child acts like the toy has disappeared. That’s achievement of object permanence, which transitions the child to the next stage of the development, (pre-operational).

Pre-operational stage is the second stage in piagets theory of cognitive development. Age from 2 to 7 years old. During this stage children imitate what they see because they’re not in that stage to use cognitive development. The child at this stage is pre (before) operations. This means a child cannot use their sense or to transform, or bring together something or separate ideas. A child development is gained through experiences in the world by adaption and towards (concrete) stage where they can use their logic thoughts. at the end of this stage children can mentally show events and objects (the semiotic function), and join in symbolic play.
