When a baby realizes that a rubber duck that fell out of the tub must be somewhere on the floor, which cognitive achievement has the child achieved?

• A. Conservation
• B. Egocentrism
• C. Assimilation
• D. Object permanence

Answer: (D)

Object permanence is the understanding that objects continue to exist even when they’re not visible. When the rubber duck falls out of the tub and the baby looks for it on the floor, they’re showing that the duck still has a location in the world even though they can’t see it right now. This is a hallmark of early cognitive development, typically emerging during the sensorimotor period as children form mental representations of objects and remember where they are. The other ideas don’t fit this exact scenario: conservation is about knowing that quantity stays the same despite changes in appearance, which isn’t what’s being demonstrated here; egocentrism is a lack of ability to take another’s point of view, not about tracking hidden objects; assimilation is a general process of fitting new information into existing mental schemes, not the specific realization that an unseen object still exists somewhere.
