It's whether a species has developed this ability spontaneously. The issue isn't whether some behavior can be learned. But more importantly, it misses the point. So these researchers basically trained some pigeons to pass the mirror mark test. There was a study using pigeons, where researchers attempted to reduce MSR to a matter of conditioning, that is, they claimed that the ability to recognize oneself in a mirror could be learned. MALE STUDENT: Wow! Do any other birds have this ability? FEMALE PROFESSOR: Well, not that we know of. And they didn't scratch at it when there was no mirror around. But eventually, some of the birds, while looking in the mirror, kept scratching at the mark until they got rid of it. At first, the magpies all engage in the same social behaviors that other animals do—looking behind the mirror, etc. So they gave them the mirror mark test, placing yellow sticker on the birds.black throat feathers. And because corvids have these other cognitive skills, researchers wanted to see if they were also capable of mirror self-recognition. So let's talk about a study recently conducted with magpies. It's been suggested in fact that jays—corvids known for stealing each other's food, may hide their food precisely because they are projecting their own tendency to steal onto other jays. And what kinds of cognitive abilities are we talking about? Well, corvids and some mammals have the ability to plan for the future, to store food for instance, in places where they can find it later. Corvids include ravens, jays, crows and magpies among others. But recently, birds have been found to possess some of the same cognitive abilities! In particular, researchers have discovered these abilities in corvids, birds of the corvidae family. ![]() Now, it's been assumed that primates and some other mammals stood alone at the top of the hierarchy of cognitive evolution. For instance, elephants will touch the mark on their heads with their trunks. But some animals, after this period of exploration, exhibit behaviors that show they know they are looking at themselves. They may even exhibit aggressive behavior. Often they will look for this animal behind the mirror. Now, typically, when animals first see themselves in the mirror, they think they are seeing another animal. In the mirror mark test, researchers put a mark on the animal where the animal is unable to see it or smell it or feel it, like on the side of their head, without looking in the mirror. FEMALE STUDENT: Well, how does it work?I-I mean.how do researchers know if elephants or chimps recognize themselves? FEMALE PROFESSOR: Researchers give them a mirror mark test. And it's called mirror self-recognition, or MSR. But it's also been found in elephants and bottlenose dolphins, a bit of a surprise. Chimpanzees and other primates,—chimps, gorillas, orangutans.and of course, humans. ![]() Today we are going to talk about a particular cognitive ability some animals seem to have—the ability to recognize themselves in a mirror. FEMALE PROFESSOR: As you know, researchers have long been interested in discovering exactly how intelligent animals are. Male Student: Yeah, I guess the idea is not practical if it means you have to take a long walk when you’ve only got a little bit of time to kill.NARRATOR: Listen to part of a lecture in an animal behavior class. What people want is somewhere they can have a little fun in between classes, kick a ball around for 15 minutes or whatever, have some fun after lunch before their next class. I mean the gym is practically on the far edge of campus, right? It’s a long walk. ![]() Male Student: Maybe, but if there’s somewhere else people could play, I mean, that could help a little.įemale Student: But it’s not a good substitute. So what Peter suggested in his letter, it wouldn’t solve anything. ![]() People are in a hurry to get to class and don’t really always walk on the paved paths or sidewalks like they are supposed to. I guess it’s right in the middle of all the busiest classroom building.įemale Student: Right. So it’s not just those students he is talking about who are responsible. But the thing is, everybody crosses that lawn every day because it’s so centrally located. I’m not sure it would really accomplish anything.įemale Student: Yeah,I mean even if they ban those students, kick them off, I’m not sure how much it would help because, sure, those guys cause some of the damage. Male Student: What do you think of this letter?įemale Student: I don’t know if a rule like that would be that helpful.
