The theory that suggests children develop the ability to learn in four basic stages is Piaget’s Four Stages of Cognitive Development. Here are the stages:

1. Sensorimotor Stage: This stage occurs between birth and age 2. Children experience the world through movement and their senses. During the sensorimotor stage, children are extremely egocentric, meaning they cannot perceive the world from others' viewpoints.

2. Preoperational Stage: The Preoperational stage is the second stage in Piaget's theory of cognitive development. This stage begins around age two and last until approximately age seven. During this period, children are thinking at a symbolic level but are not yet using cognitive operations.

3. Concrete Operational Stage: The Concrete Operational stage is the third stage in Piaget's theory of cognitive development. This period spans the time of middle childhood—it begins around age 7 and continues until approximately age 11—and is characterized by the development of logical thought.

4. Formal Operational Stage: The Formal Operational stage is the fourth and final stage in Piaget's theory. It begins at approximately age 12 and lasts into adulthood. During this time, people develop the ability to think about abstract concepts. Skills such as logical thought, deductive reasoning, and systematic planning also emerge during this stage.
