Subject: DawnWatch: Huge Wall Street Journal Weekend article on animal intelligence — 10/27/06
The Friday, October 27, Wall Street Journal has huge article on the front page of the Weekend Journal section (W1) headed, “What Your Pet is Thinking.” The article, by Sharon Begley, actually focuses not on “your pet” but on nonhuman intelligence.
It opens with the description of a dog who hated the sound of the ringing telephone so would pick up the receiver and put it back down again to shut it up.
We read about research animal intelligence are told:
“The research is also coloring thinking about everything from science labs to farms and food-production facilities.”
I will share the passage on the test of primate awareness:
“At the Yerkes National Primate Research Center in Atlanta, Robert Hampton, who has made some of the field’s most significant findings, studies whether rhesus monkeys know if they know something. In one series of experiments, he gave the monkeys memory tests over a period of weeks. After seeing four images on a monitor, the monkeys would be asked to choose which one they had seen before. But before taking the test, the monkeys had a choice of pressing one of two icons whose meaning they already knew. One meant, ‘Yup, I’m ready to take the test.’ The other meant, ‘No test for me, thanks.’ They had an incentive to take it only if they remembered the target image: Failing the test brought them no reward, passing it got them a handful of peanuts, and declining to take the test got them monkey-chow pellets, which they don’t like as much as peanuts but are better than nothing.
“When the monkeys chose to take the test, they passed more than 80% of the time, apparently declining to take the test when their memory was poor. When they weren’t given a choice and Prof. Hampton gave them the test anyway, they chose the correct image much less often. That suggests they knew the contents of their memory and assessed it before deciding whether to take the test — a sign of self-reflective consciousness. ‘The monkeys know whether they remember something,’ says Prof. Hampton, who reported his latest monkey findings in May in the journal Behavioural Processes.”
It is disturbing to read about monkeys held captive in facilities nothing like their native jungles, just so that we can perform tests that satisfy our curiosity about their thinking. But given that primates are still used in lethal tests for new household products, or for studying illegal drugs such as ecstasy, perhaps we have to be willing, for now, to accept the tests that bring knowledge that we hope will make those lethal tests illegal.
