One-year old miguel loves his stuffed rabbit and will stare at it and reach for it when it's waved in front of him. but when the rabbit is placed behind a curtain, he doesn't realize that it's still there. according to piaget, what stage of cognitive development is miguel in?

According to Piaget's theory of cognitive development, Miguel is in the sensorimotor stage of development. During this stage of cognitive development-which spans from age 0-2 years in infants - infants lack object permanence. This means that infants have not developed the ability to understand that objects continue to exist even if they are hidden from them or no longer in view.
