Primary circular reaction first occurs in the sensorimotor stage, and is subsequent to the development of the infant's reflexive actions like crying and squirming.

The six sub-stages are: reflexes, primary circular reactions, secondary circular reactions, coordination of reactions, tertiary circular reactions and early representational thought. As babies progress through each sub-stage, they continue to develop cognitive, or thinking, skills to further their overall development.

Substage 4: Coordination of Secondary Circular Reactions 8 months to 12 months. Beginning of goal-directed behavior Several schemes are combined and coordinated to generate single act to solve problem Means to attain particular ends and skill in anticipating future circumstances due in part to object permanence.

The third stage of sensorimotor development is secondary circular reactions. This sub-stage usually occurs when the baby reaches around 4 months of age and may continue through 8 months of age. When babies are in this sub-stage of development, they begin to realize that objects that drop from view are no longer there.

Primary Circular Reactions. The second sub-stage of sensorimotor development is primary circular reactions. A primary circular reaction occurs at around 1-4 months of age and might include when a baby brings his thumb to his mouth to suck on.

Constructivism. 'Knowledge is not a copy of reality. To know an object, to know an event, is not simply to look at it and make a mental copy or image of it. To know an object is to act on it. To know is to modify, to transform the object, and to understand the process of this transformation, and as a consequence to understand the way the object is constructed.'(Piaget, 1964: 8).
