Answer:
coordination of secondary circular reactions
Explanation:
Given by Jean Piaget in his child developmental theory.
The sensorimotor stage consists of six sub-stages that lasts from birth to twenty-four months of age.
Sub-stages:
1. Reflexes.
2. Primary circular reactions.
3. Secondary circular reactions.
4. Coordination of reactions.
5. Tertiary circular reactions.
6. Early representational thought.
Secondary Circular Reactions: This sub-stage lasts from four to eight months. In this sub-stage, the child focuses on the world and repeats an action that triggers a response intentionally in the environment. In short, they are involved in pleasurable activities that come either from an object or from their bodies.
