Children learn that they are separate from the environment. They can think about aspects of the environment, even though these may be outside the reach of the child's senses. In this stage, according to Piaget, the development of object permanence is one of the most important accomplishments. [18]
According to Piaget, "the child is someone who constructs his own moral world view, who forms ideas about right and wrong, and fair and unfair, that are not the direct product of adult teaching and that are often maintained in the face of adult wishes to the contrary" (Gallagher, 1978, p. 26).
Piaget came up with a theory for developmental psychology based on cognitive development. Cognitive development, according to his theory, took place in four stages. [1] These four stages were classified as the sensorimotor, preoperational, concrete operational and formal operational stages.
A child who cannot conserve will assume the taller glass has more liquid than the shorter glass. Piaget’s other famous task to test for the conservation of liquid involves showing a child two beakers, A1 and A2, which are identical and which, the child agrees, contain the same amount of colored liquid.
His main contribution is the stage theory of child cognitive development. He also published his observational studies of cognition in children, and created a series of simple tests to reveal different cognitive abilities in children. Piaget believed that people move through stages of development that allow them to think in new, more complex ways.
Through observations of children, Jean Piaget established a theory of cognitive development. According to Piaget's theory of cognitive development there are four stages of cognitive development. [8] [9] Sensorimotor Stage (Birth to 24 Months) Preoperational Stage (24 Months to 7 Years) Concrete Operational Stage (7 Years to 12 Years)
According to Piaget, horizontal and vertical décalage generally occur during the concrete operations stage of development. [2] Horizontal décalage refers to fact that once a child learns a certain function, he or she does not have the capability to immediately apply the learned function to all problems.
According to Piaget, one of the main obstacles to logic that children possess includes centration, "the tendency to focus on one aspect of a situation to the exclusion of others". [13] A particular type of centration is egocentrism – literally, "self-centeredness".
