Detailed explanation-1: -According to Piaget, children have four stages of development which he classified as Sensorimotor, Preoperational, Concrete Operational, and Formal Operational. In each of these stages, children continually add new knowledge, build upon existing knowledge, and adapt previously held ideas to accept new information.

Detailed explanation-2: -Piaget proposed four major stages of cognitive development, and called them (1) sensorimotor intelligence, (2) preoperational thinking, (3) concrete operational thinking, and (4) formal operational thinking. Each stage is correlated with an age period of childhood, but only approximately.

Detailed explanation-3: -Preschooler development at 4-5 years: what’s happening. At this age, preschoolers are exploring and learning to express emotions. They do this in many ways – for example, by talking, using gestures, making noises and playing.

Detailed explanation-4: -Stage 4. Coordination of secondary circular reactions (infants between 8 and 12 months). At this stage, infants’ behavior becomes goal-directed in trying to reach for an object or finding a hidden object indicating they have achieved object permanence.
