Jean Piaget’s theory of knowledge

• Piaget became interested in the nature of thought and the development of thinking.

• He called his studies genetic epistemology which is the study of the development of knowledge.

• Schemas are skills that people even infants obtain that enables them to explore their environment and gain more knowledge of the world and gain more sophisticated skills.

Assimilation and Accommodation• Assimilation- specifically assimilating a new object into an old

schema.• Accommodation- specifically accommodating an old schema to a

new object.• Assimilation and accommodation are two aspects of adaptation,

also known as learning.• Piaget saw adaptation (learning), as a fundamentally biological

process because people have to learn how to accommodate and assimilate. For accommodation, we take old habits and try to apply them to new situations. With assimilation, we take new habits and try to make them so they apply to our old ones

• Equilibrium- assimilation and accommodation are directed at a balance between the structure of the mind and the environment, as a certain congruency between the two, that would indicated you have a good model of the universe.

Piaget’s Stages of Cognitive Development

Sensorimotor Stage•Primary Circular Reactions (1-4 months)- an action of his own which serves as a stimulus to which it responds with the same action.•Secondary Circular Reactions (4-12 months)- an act that extends out to the environment.•Tertiary Circular Reactions (12-24 months)- these reactions consist of the same “making interesting things last” cycle, except with constant variation.•Mental Representation (1 ½ years old)- the ability to hold an image in their mind for a period beyond the immediate experience.•Deferred Imitation- throwing a tantrum after seeing another toddler doing one an hour before.•Mental Combinations- solving simple problems.

Preoperational Stage, Concrete Operations Stage, and Formal

Operations Stage• Preoperational Stage (2-7 years old)- Piaget noted that

children in this stage do not yet understand concrete logic, cannot mentally manipulate information, and are unable to take the point of view of other people, which he termed egocentrism.

• For example, if a liquid was poured into a small glass and the same amount of liquid was poured into a taller glass and a child was asked which glass has more, they wouldn’t be able to tell. They would think that the taller glass has more because it appears to have more.
