Which of the following is not one of Piaget's stages?

• A. Sensorimotor
• B. Visual-spatial stage
• C. Preoperational
• D. Concrete operational

Answer: (B)

Think about how children's thinking changes in distinct, organized steps according to Piaget. He outlined four main stages of cognitive development that describe the quality of thinking rather than just how much a child knows.

The first stage, from birth to about age two, is the sensorimotor stage. During this period, learning happens through direct sensory and motor interaction with the world, and children develop object permanence—the understanding that things continue to exist even when they can’t see them.

The second stage, roughly ages two to seven, is the preoperational stage. Here, children begin to use language and symbols, but their thinking is still intuitive and egocentric; they struggle with taking others’ perspectives and with understanding that quantities stay the same despite changes in appearance (the concept of conservation isn’t fully developed yet).

The third stage, from about seven to eleven, is the concrete operational stage. Children become capable of logical thinking about concrete objects and events, understand conservation more fully, and can reason about categories and collections with more accuracy.

The fourth stage, starting around adolescence and continuing into adulthood, is the formal operational stage. This stage features abstract, hypothetical, and deductive reasoning.

The option Visual-spatial stage is not part of Piaget’s framework. It’s a concept related to spatial processing, but Piaget did not define a separate stage named Visual-spatial; the four stages above are the ones he proposed.
