A researcher shows 3-month-old infants a toy car rolling down a ramp and passing behind a screen. In one test event, a solid block is placed on the track behind the screen. The car is then shown to roll down the ramp and reappear on the other side of the screen, as if it had passed through the block. Researchers find that infants look significantly longer at this event compared to an event where the car is stopped by the block. What is the most logical conclusion to draw from this specific finding?
