1.What is the main purpose of the lecture?
A. To show that some birds have cognitive skills similar to those of primates
B. To explain how the brains of certain primates and birds involved
C. To compare different tests that measure the cognitive abilities of animals
D. To describe a study of the relationship between brain size and cognitive abilities
2.When giving magpies the mirror mark test, why did researchers place the mark on the magpies’ throats?
A. Throat markings trigger aggressive behavior in other magpies.
B. Throat markings are extremely rare in magpies.
C. Magpies cannot see their own throats without looking in a mirror.
D. Magpies cannot easily remove a mark from their throats.
3.According to the professor, some corvids are known to hide their food. What possible reasons does she provide for this behavior?
Click on two answers.
A. They are ensuring that they will have food to eat at a later point in time.
B. They want to keep their food in a single location that they can easily defend.
C. They have been conditioned to exhibit this type of behavior.
D. They may be projecting their own behavioral tendencies onto other corvids.
4.What is the professor’s attitude toward the study on pigeons and mirror self-recognition?
A. She is surprised that the studies have not been replicated.
B. She believes the study’s findings are not very meaningful.
C. She expects that further studies will show similar results.
D. She thinks that it confirms what is known about magpies and jays.
5.What does the professor imply about animals that exhibit mirror self-recognition?
A. They acquired this ability through recent evolutionary changes.
B. They are not necessarily more intelligent than other animals.
C. Their brains all have an identical structure that governs this ability.
D. They may be able to understand other animal’s perspective.
6.According to the professor, what conclusion can be drawn from what is now known about corvids’ brains?
A. The area in corvids’ brains that governs cognitive functions governs other functions as well.
B. Corvids’ brains have evolved in the same way as other birds’ brains,only more rapidly.
C. Corvids’ and primates’ brains have evolved differently but have some similar cognitive abilities.
D. The cognitive abilities of different types of corvids vary greatly.
