Tertiary circular reactions occur around which age?

Explanation:
In Piaget’s sensorimotor development, the phase where infants begin to experiment with new ways of acting on objects to see different outcomes is when they enter tertiary circular reactions. This involves purposeful, trial-and-error exploration—the child repeats actions with variations to learn how things work. The age range that fits this curious, experimental behavior is about 12 to 18 months. Earlier months are dominated by reflexes and simpler repetitive actions, while after 18 months thinking becomes more internal and symbolic.
