Concept:Piaget's theory of cognitive development has four stages. The infancy period (birth to 2 years) corresponds to the sensorimotor stage, where infants learn through senses and actions.
Explanation:Jean Piaget identified four cognitive stages: sensorimotor, preoperational, concrete operational, and formal operational.
The sensorimotor stage lasts from birth to about 2 years. Infants explore the world using their senses (seeing, hearing, touching) and motor abilities (grasping, crawling).
Key features include object permanence, early representational thought, and coordination of senses with movements. This stage ends with the development of symbolic thought.
The other options are for later ages: preoperational (2–7 years), concrete operational (7–11 years), and formal operational (11+ years). Therefore, the correct stage for infancy is sensorimotor thought.
Answer:C. Sensorimotor thought
