Piaget's Theory of Cognitive Development from Childhood into Adulthood

Jean Piaget emphasized children's cognitive development, asserting that thinking plays a central role and that children have an inherent curiosity.

Piaget's theory proposes that cognitive abilities evolve through distinct stages, reflecting a discontinuous approach to development.

He proposed that children actively create mental concepts, called schemata, to understand the world around them, such as sucking, which is an early, basic schema. By adulthood, schemata become more complex expectations and beliefs about the world.

As children encounter new information, they adjust their schemata through two fundamental processes: assimilation and accommodation.

Assimilation involves integrating new information into existing schemata. For example, after interacting with a family pet, a child forms a schema for dogs. They then identify other dogs in books, assimilating them into their schema.

In contrast, accommodation occurs when children modify their schemata in response to new information. For instance, when the child sees a sheep and calls it a dog, they adjust their schema after being corrected, accommodating new information to distinguish between dogs and sheep.
