- 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.
- According to the professor, some corvids are known to hide their food. What possible reasons does she provide for this behavior?
[CHOOSE 2 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.
- 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.
- 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 another animal’s perspective.
- 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.
