Rather, he believed that cognitive development is more like a process which occurs due to biological maturation and interaction with the environment. Through his studies on cognition in children, a series of simple but clever tests revealed different cognitive abilities in children at different age stages. Children from birth understand their environment through cognitive development stages that are sensorimotor, preoperational, concrete operational, and formal operational.

For example, children at ages from birth to 2 months interact with their environment through sucking and grasping their toys. As children continue growing at this stage, they develop early speech and realize that their actions affect their surroundings; like when they shake their toy, a sound may start playing. The most important substage of the Sensorimotor stage is object permanence which is
