Which substage is not part of the sensorimotor stage?

• A. Tertiary circular reactions
• B. Preoperational
• C. Primary circular reactions
• D. Coordination of reactions

Answer: (B)

Understanding Piaget's sensorimotor stage means recognizing that infants learn through action and direct experience, and this period is divided into six substages that describe increasingly complex ways of acting on the world. The options listed reflect substages of this period: primary circular reactions involve repeating an action centered on the infant’s own body, coordination of reactions involves combining schemes to solve problems, and tertiary circular reactions explore different actions to see varied outcomes. The phrase that isn’t part of the sensorimotor stage is the other main stage that follows, where thinking becomes symbolic, language emerges, and children start to use mental representations. That stage begins after the sensorimotor period, so it is not a sensorimotor substage.
