Basic Cognitive Concepts (Schema, Assimilation, Accommodation, Equilibration)

This section introduces Jean Piaget's 60 years of research on cognitive development, highlighting his observation-based research method. It then lists the basic cognitive concepts to be discussed: schema, assimilation, accommodation, and equilibration.

Schema refers to the cognitive structures individuals use to adapt to and organize their environment. It's like a mental filing cabinet where experiences are stored. An example is given of a child seeing a dog for the first time and creating a schema for it based on its characteristics (four legs, tail, barks, furry).

Assimilation is the process of integrating a new experience into an existing schema. If the child from the previous example sees another dog, even a smaller one, they assimilate this new information into their existing 'dog' schema.

Accommodation involves creating a new schema when an existing one cannot adequately explain a new experience. If the child sees an animal that resembles a dog but is different (e.g., a goat), and is corrected by a parent, they create a new schema for 'goat'.

Equilibration is the process of achieving balance between assimilation and accommodation. Humans naturally seek order and predictability. Cognitive disequilibrium occurs when experiences don't match existing schemata, leading individuals to use assimilation and accommodation to re-establish equilibrium.
