Q

5 substages of sensorimotor development:

A
  1. Simple reflexes (0-1 month) - cognitive activity is based on the neonatal reflexes such as sucking, rooting and grasping.
  2. First habits and primary circular reaction (1-4 months) - activities based less on reflexes and more on purposeful movements (repeated bodily movements, sucking of hands and fingers)
  3. Secondary circular reactions (4-8 months) - same as first circular reaction but reactions involve external activities (kicking a hanging mobile over and over as it bring joy)
  4. Coordination of secondary schemes (8-12 months) - FIRST intentional actions, goal directed behaviour, coordination of schemas (reaching, grasping, moving objects)
  5. Tertiary circular reactions (12-18 months) - TRIAL and ERROR, intentionally test to see what the effects will be. FULLY INTENTIONAL.
