In Piaget’s theory, which stage features the predominance of reflexes in driving thought and action?

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

Answer: (D)

In this stage, thinking is tied directly to action and is guided by innate reflexes. From birth, infants respond to the world through reflexive behaviors like sucking, grasping, and orienting, and these reflexes largely drive what they do. As the baby interacts with people and objects, these reflexive actions are gradually organized into more purposeful patterns, so behavior becomes increasingly controlled by internal schemes that emerge from those sensorimotor experiences. This period, lasting up to about two years, is characterized by learning through doing rather than through language or abstract thought. A key milestone is object permanence—the understanding that things continue to exist even when not directly perceived—which develops as the infant’s actions and experiences accumulate. The other stages move beyond reflex-driven action to include symbolic thought, logical operations on concrete objects, and later abstract reasoning, so they don’t focus on reflexes as the primary driver of thought and behavior.
