Question

In developmental psychology, which stage is characterized by the development of object permanence?

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

Hint:

Remember, object permanence is a fundamental concept acquired during the sensorimotor stage of infancy.

Answer 1

The Correct Option is A

Key Concept: Piaget's cognitive development stages are each defined by a specific new ability the child gains.

Why it's correct: The Sensorimotor stage (birth to ~2 years) is when infants develop object permanence — understanding that objects continue to exist even when out of sight.

Why others fail: Preoperational, Concrete operational, and Formal operational stages come later and are defined by different milestones (symbolic thought, logic, abstract reasoning) — object permanence is already achieved by then.
