Suppose you observe a baby sitting in front of a mirror. You now place a dot of rouge on the baby's nose. You see the baby look at the mirror, and then he crawls around the mirror to find the baby on the other side. Your best guess is that this baby is about how old?

Question

Previous research has shown that between 8 and 16 months of age, babies will sometimes crawl around the mirror to try to find the other baby. If a researcher puts a dot of red rouge on the baby's nose, the baby notices it but points to the nose in the mirror and not to his or her own nose.
