The Sensorimotor stage ends around what age?

• A. 3 years
• B. 4 years
• C. 2 years
• D. 5 years

Answer: (C)

The main idea tested is how long the thinking of infancy is primarily action-based. The Sensorimotor stage covers learning through doing—reflexes developing into intentional actions and later problem-solving with objects. This period typically spans from birth up to around the second birthday, because around age two children begin to think more symbolically, use words, and engage in pretend play, which signals the move into the next stage (preoperational). So, the end is about 2 years old. Ages like 3, 4, or 5 would fall into the subsequent stages, not the sensorimotor one. Some references note a transition near 18–24 months, but the common exam benchmark is around 2 years.
