Talk to the Animals


Most pet owners talk to their animals at one time or another, and some do every day. But, how much do our pets actually understand? Is their perception anything like our own? These are the questions that fascinate Irene Pepperberg and she's looking for answers from the animals themselves, specifically African Grey Parrots. The Harvard psychology professor is researching how much the birds understand about shapes, numbers and colors.
