Jean Piaget suggested that children undergo four distinct stages of cognitive development, each representing different qualitative modes of thinking. The sensorimotor stage, which spans from birth to approximately 2 years, is particularly significant for infants and toddlers. In this stage, children primarily acquire knowledge through their senses and motor activities, such as touching, grasping, observing, and moving. Throughout this period, infants gradually attain object permanence, which is the realization that objects continue to exist even when they are not visible, and they start to engage in goal-oriented behaviors and symbolic thinking. Piaget highlighted that children are proactive learners, constructing their understanding through exploration, experimentation, and reflection, rather than merely absorbing information passively.
