Document Summary
Organized ways of making sense of experience. Schemes change with age: first schemes: sensorimotor action patterns, later schemes: deliberate and creative. Adaptation: building schemes through direct interaction with environment: assimilation: using current schemes to interpret the external world, accommodation: adjusting old schemes and creating new ones to better fit environment, balance between assimilation and accommodation varies over time. Cognitive equilibrium: steady, comfortable state when children are not changing much, characterized by assimilation more than accommodation. Cognitive disequilibrium: state of cognitive discomfort, shift from assimilation toward accommodation, then back toward assimilation. Building schemes through sensory and motor exploration. Primary circular reactions (1-4 months): simple motor habits centred around own body. Secondary circular reactions (4-8 months): repetition of interesting effects: imitation of familiar behaviours. Coordination of secondary circular reactions (8-12 months): intentional, goal- directed behaviour; beginning object permanence. Tertiary circular reactions (12-18 months): exploration of object properties through novel actions.
