Which Piaget stage spans from birth to about 2 years and is characterized by the infant's lack of symbolic function while interacting with the environment?

• A. Sensorimotor
• B. Preoperational
• C. Concrete Operational
• D. Formal Operational

Answer: (A)

In Piaget’s theory, early infancy is dominated by learning through action and sensation—the sensorimotor stage. During this period, babies interact with the world by using their senses and motor skills, starting from simple reflexes and progressively coordinating actions to explore objects. They rely on what they can directly perceive and do, not on internal mental symbols or representations. The idea of thinking with words, images, or symbols doesn’t emerge yet; understanding grows through repeated physical interactions with people and objects, such as grasping, mouthing, and shaking things. By the end of this stage, infants begin to show object permanence and more intentional behavior, but symbolic thought isn’t fully developed until the next stage. The other stages involve the emergence and use of symbolic thought and logical operations that come later, so they don’t match the description of infancy’s lack of symbolic function and primary reliance on interacting with the environment.
