Jean Piaget is known as a child psychologist. He researched young children and their development to better understand human personality and stages of development.

"Jean Piaget may be termed a foundational thinker. He delved beneath prejudices, biases and encrusted habits in order to uncover the essential well-springs of cognitive life" (Schumaker, 1996).

It is noted that Piaget's work combines learning with life's essential questions, and it is "one of our century's greatest treasures" (Schumaker, 1996).

Piaget conducted studies and observations that offered information to cognitive development of children.

Using his own children, Piaget approached the study first by focusing on experiences and qualities of the children. Second, he studied their behavior using questions and hypothesis from his earlier work.  (Levy, 1976).

Jean Piaget's cognitive theory "states that children actively construct their understanding of the world and go through four stages of cognitive development" (Santrock, 2013). Two processes, organization and adaptation, are the basis for the four stages of development.

This theory suggests that we organize and adapt to our observations and experiences.

"Children begin to go beyond simply connecting sensory information with physical action and represent the world with words, images, and drawings" (Santrock, 2013).

Piaget believed that preschool children lack the ability to perform internal mental actions, or operations.

Birth to 2 Years of Age

"Infants construct an understanding of the world by coordinating sensory experiences (seeing and hearing) with physical, motoric actions" (Santrock, 2013).

"An infant progresses from reflexive, instinctual action at birth to the beginning of symbolic thought toward the end of the stage" (Santrock, 2013).
