Verified step by step guidance

1. Understand Piaget's Cognitive Developmental Theory, which divides cognitive development into four main stages: Sensorimotor, Preoperational, Concrete Operational, and Formal Operational.
2. Recall that object permanence is the understanding that objects continue to exist even when they cannot be seen, heard, or touched.
3. Identify which stage is characterized by the development of object permanence. According to Piaget, this occurs during the Sensorimotor stage.
4. Note that the Sensorimotor stage typically spans from birth to about 2 years of age, during which infants learn through sensory experiences and motor activities.
5. Conclude that a child who has just developed object permanence is in the Sensorimotor stage, distinguishing it from the other stages where different cognitive abilities emerge.
