Which stage is described as Birth to 2 years, in which infants learn through sensation and movement?

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

Answer: (A)

During the sensorimotor stage, birth to about two years, infants learn by acting on the world and using their senses. They move from reflexive actions to more deliberate actions as they explore how things feel, look, and work. Object permanence—knowing that objects still exist even when not seen—emerges in this period, signaling a shift toward more complex interactions with the environment. In contrast, later stages focus on using symbols and language, applying logical reasoning to concrete objects, and eventually abstract thinking.
