The whole idea of trying to discern complex insight from watching behavior disturbs Sara Shettleworth of the University of Toronto, who studies animal cognition. He argues that the brain structure itself favors elephant-type memory and social empathy instead of more integrative processes. The new demonstration of insight isn’t enough to change the basic view of savantlike elephant brains for Benjamin Hart of University of California, Davis School of Veterinary Medicine, who has studied elephant behavior. Elephants have been called savantlike, in recognition of their superb memories but lackluster performance in some other human-designed cognitive challenges. If elephants can solve problems by insight, then maybe their brains are better at integrating information than they’ve been given credit for, says study coauthor Diana Reiss of Hunter College in New York. Earlier tests for elephant insight may not have had the right elephant-friendly choices at hand to detect insight, Foerder and his colleagues suggest. #Drunk elephant aha moment how to#His mother, age 33 at the time of test, and their 61-year-old unrelated female neighbor never figured out how to reach the fruit. And he moved the cube to another part of the compound to reach mouthfuls of flowers on a tree overhanging the fence. He also expanded on this discovery, standing on a tire or a plastic ball. He’d been observed standing on objects before, but not moving them to improve his reach. “That was my ‘aha’ moment,” Foerder says.Īfter six sessions of failing to reach the fruit, the youngest elephant, Kandula, went over to a cube left in his cage for him to play with and repositioned it to use it as a step up to the fruit. ![]() He added things for the animals to stand on, thinking that perhaps elephants wouldn’t be inclined to grasp food with a stick if it impaired their ability to sniff with their trunk. Then Foerder moved the test outdoors and suspended the fruit as if it were hanging from a tree. One elephant even angled the stick through cage bars as if trying to pry them apart. “They would beat the wall they would beat the floor they would beat their toys,” Foerder says. Elephants strained mightily to reach far-flung fruit trays but didn’t try to pull the food in with sticks provided by the scientists. At first he offered fruit pieces on trays outside the bars of their enclosures. He worked with three Asian elephants at the Smithsonian National Zoological Park in Washington, D.C. #Drunk elephant aha moment trial#However, Foerder laments, “If you’re not there for the first time they do it, you don’t know if it was insight.” An elephant might have figured out the trick by trial and error or by watching other animals do it.įoerder’s own tests for insight started with trials and errors. Elephants clearly solve problems in the wild, such as using fallen trees as bridges to safely cross electric fences protecting farmers’ crops. Similar experiments have revealed possible insightful problem solving in such animals as chimps, orangutans, gibbons, baboons, parrots and members of the crow family, Foerder says. But the pachyderms haven’t done well on tests of a particular type of problem solving: getting a sudden flash of insight instead of finding solutions through trial and error. Elephants do have some smarts, including excellent long-term memory and skill with tools. ![]()
