Piaget

Piaget was the first psychologist to make a systematic study of cognitive development.  His contributions include a theory of cognitive child development, detailed observational studies of cognition in children, and a series of simple but ingenious tests to reveal different cognitive abilities.

Piaget showed that young children think in strikingly different ways compared to adults.  According to Piaget, children are born with a very basic mental structure (genetically inherited and evolved) on which all subsequent learning and knowledge is based, he became intrigued with the reasons children gave for their wrong answers on the questions that required logical thinking. He believed that these incorrect answers revealed important differences between the thinking of adults and children.

Piaget's Theory Differs From Others In Several Ways:

Concerned with children, rather than all learners.

Focus on development, rather than learning

Stages of development, marked by qualitative differences, rather than a gradual increase in a number and complexity of behaviors, concepts, ideas,etc.

The goal of the theory is to explain the mechanisms and processes by which the infant, and then the child, develops into an individual who can reason and think using hypotheses. 

To Piaget, cognitive development was a progressive reorganization of mental processes as a result of biological maturation and environmental experience. Children construct an understanding of the world around them, and then experience discrepancies between what they already know and what they discover in their environment.

Basic Components of Piaget's Cognitive Theory:

-Schemas or building blocks of knowledge

-Processes that enable the transition from one stage to another, equilibrium, assimilation, and accommodation.

-Stages of Development: Sensory, Preoperational, concrete operational, formal operational

Schemas: Piaget called the schema the basic building block of intelligent behavior a way of...
