Period starting from birth to two years in cognitive development is: (a) Sensorimotor stage (b) Preoperational stage (c) Concrete operational stage (d) Formal operational stage ✅ Correct Option: (a) Sensorimotor stage Explanation: The sensorimotor stage, according to Piaget, spans birth to 2 years. During this period, infants learn about the world through senses and motor activities. Knowledge is not symbolic; children interact with their environment directly by grasping, sucking, looking, and moving. Key developments include: Object permanence: Understanding that objects exist even when unseen. Cause and effect: Realizing actions can produce outcomes. Early problem-solving: Simple actions to achieve desired results. This stage forms the foundation for later cognitive abilities. Preoperational, concrete, and formal operational stages occur after age 2. 10 PPSC-Relevant Facts: 1. Sensorimotor: birth–2 years 2. Learning via senses and actions 3. Object permanence develops 4.
