Question

Discuss the stage of Cognitive Development.

Answer 1

The Piaget stages of development is a blueprint that describes the stages of normal intellectual development, from infancy through adulthood. This includes thought, judgment, and knowledge. The stages were named after psychologist and developmental biologist Jean Piaget, who recorded the intellectual development and abilities of infants, children, and teens.


Sensorimotor. Birth through ages 18-24 months

Preoperational. Toddlerhood (18-24 months) through early childhood (age 7)

Concrete operational. Ages 7 to 12

Formal operational. Adolescence through adulthood

Answer 2

Through a series of stages, Piaget proposed four stages of cognitive development: the sensorimotor, preoperational, concrete operational and formal operational period. The sensorimotor stage is the first of the four stages in cognitive developmentwhich "extends from birth to the acquisition of language".Piaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence. It was first created by the Swiss developmental psychologist Jean Piaget (1896–1980). The theory deals with the nature of knowledgeitself and how humans gradually come to acquire, construct, and use it. Piaget's theory is mainly known as a developmental stage theory.

To Piaget, cognitive development was a progressive reorganization of mental processes resulting from biological maturation and environmental experience. He believed that children construct an understanding of the world around them, experience discrepancies between what they already know and what they discover in their environment, then adjust their ideas accordingly. Moreover, Piaget claimed that cognitive development is at the center of the human organism, and language is contingent on knowledge and understanding acquired through cognitive development. Piaget's earlier work received the greatest attention.

Child-centered classrooms and "open education" are direct applications of Piaget's views. Despite its huge success, Piaget's theory has some limitations that Piaget recognized himself: for example, the theory supports sharp stages rather than continuous development (horizontal and vertical décalage).
