Sensorimotor stage
Tertiary circular stage is the sub stage of sensorimotor development which happens between 12-18 months of age. At this stage, the infant passes through tertiary circular reactions of innovation and curiosity. These circular reactions are the designs in which a child deliberately investigates new possibilities with the objects and frequently involve in doing new things and searching new events.
Think of it like this — if American leaders had never made the *decision* to break away from Britain, America would still be a colony of Britain.
Decision making determines the course of events. This is because a certain decision will then trigger certain actions, which in the grand scheme of things will impact history.
Example; American leaders made the *decision* to break off from Britain, triggering the Revolutionary War and America’s Independence, thus that decision changed history.
