Piaget's theory is divided into four distinct stages of cognitive development:
Sensorimotor Stage (Birth to 2 years): During this period, infants learn about the world through their senses and actions. They develop object permanence, realizing that objects continue to exist even when they cannot see them. Preoperational Stage (2 to 7 years): In this stage, children begin to use language to explore and understand their worlds. They exhibit egocentric thinking, meaning they have difficulty seeing things from perspectives other than their own. Concrete Operational Stage (7 to 11 years): Here, children start thinking logically about concrete events. They gain a better understanding of the concept of conservation—that quantity remains the same despite changes in shape or arrangement. Formal Operational Stage (12 years and up): Adolescents develop the ability to think about abstract concepts. They can hypothesize and use deductive reasoning.
