I continue to be baffled by research such as this:
It was once thought that only humans could pass the mark test. Then chimpanzees did, followed by dolphins and elephants.
What I continue to not understand is why they don’t think that (e.g.) cats are self aware. My cats recognize each other, so they clearly recognize cats. When they see themselves in a mirror, they don’t treat it like another cat — they basically ignore it. Is there any other explanation for this than they recognize it as themselves? What am I missing here?
According to Emory University primatologist Frans de Waal, the new findings fit with his work on capuchin monkeys who don’t quite recognize themselves in mirrors, but don’t treat the reflections as belonging to strangers. “As a result, we proposed a gradual scale of self awareness. The piece of intriguing information presented here may support this view,” he said.
However, de Waal cautioned that “many scientists would want more tests and more controls” — a warning especially salient in light of a high-profile controversy involving Marc Hauser, a Harvard University evolutionary biologist who appears to have overstated the cognitive powers of his own monkeys.
“What you’re seeing in the videos is subject to all kinds of interpretations,” said Gordon Gallup, a State University of New York at Albany psychologist who invented the mirror test, and has administered it with negative results to rhesus monkeys. “I don’t think these findings in any way demonstrate that rhesus monkeys are capable of recognizing themselves in mirrors.”
It seems to me that, for whatever reason (Homo Sapiens chauvinism?), some scientists go out of their way to deny the obvious. It reminds me of the arguments during Descartes’s day that animals couldn’t feel pain, and the even more absurd ones that babies couldn’t, either, used as an excuse to not have to use anaesthesia to operate on them.
[Update a while later]
I should add that there is no definitive test for self awareness. There is no way to know for certain that anyone other than yourself is self aware.
