Alex, The Brainy Parrot Who Knows About Zero

Roland Piquepaille writes "Alex is a 28-year-old grey parrot who lives in a lab at Brandeis University in Waltham, Mass., and can count, identify objects, shapes, colors and materials. And now, Alex has grasped the concept of zero, according to World Science. In fact, Alex can describe the absence of a numerical quantity on a tray containing colored cubes. When a color is missing, Alex consistently identified this 'zero quantity' by saying the label 'none.' You might think that this is just a parrot trick, but this research about 'bird intelligence' might also help autistic and other learning-disabled children 'who have trouble learning language and counting skills.' This overview contains other details, references and a picture of Alex counting his colored cubes."

    This just goes how much we underestimate animals and overvalue ourselves. We'd like to believe that the evolution gap between us and every other species is too broad to be even fathomed, but it's simply not true. I know some people will reply and say that we all know that we came from apes, but I'm not talking about what we know, but how we act. We treat animals like they don't have emotions and that they aren't capable of the same types of understanding as us. In the future I imagine we are going to see that animals can do a lot of things we never though and are even better than us in some areas of intellect.

    Alex is a 28-year-old grey parrot who lives in a lab at Brandeis University in Waltham, Mass., and can count, identify objects, shapes, colors and materials. And now, Alex has grasped the concept of zero, according to World Science. In fact, Alex can describe the absence of a numerical quantity on a tray containing colored cubes.

Read more...

    One of the really interesting things about Alex is that it had learned in the past that "none" meant a lack of information. And without any training, when Alex was asked to say how many green or red cubes were on a tray in front of him, he spontaneously said "none" when there was no cubes with this color. In fact, he was able to connect two different concepts, a lack of information and the absence of a quantity. Pretty brilliant parrot, isn't?

    Before going further, below is a picture of Alex in front of his counting blocks (Credit: Brandeis University). And here is a link to a larger version (193 KB).

    Now, let's look at how the researchers made the discovery that Alex possessed a "zero-like concept."

    The story began when researchers started testing Alex to see whether he understood small numbers, between one and six. Zero wasn't expected of him. The researchers would lay out an array of objects of different colors and sizes, and asked questions such as "what color four?" -- meaning which color are the objects of which there are four.

    Apparently, Alex was pretty good on these tests, until he got bored. So the researchers "found some more interesting toys to give as rewards." And here came the decisive experiment.

    One of these apparent lapses occurred one day when an experimenter asked Alex "what color three?" Laid out before Alex were sets of two, three and six objects, each set differently colored. Alex insisted on responding: "five." This made no sense given that the answer was supposed to be a color.

    After several tries the experimenter gave up and said: "OK, Alex, tell me: what color five?" "None," the bird replied. This was correct, in that there was no color that graced exactly five of the objects. The researchers went on to incorporate "none" into future trials, and Alex consistently used the word correctly, they said.

    A few days after this article was published, Brandeis University decided to issue a press release adding that Alex was the "first bird to comprehend numerical concept akin to zero."

    "It is doubtful that Alex's achievement, or those of some other animals such as chimps, can be completely trained; rather, it seems likely that these skills are based on simpler cognitive abilities they need for survival, such as recognition of more versus less," explained comparative psychologist and cognitive scientist Dr. Irene Pepperberg.

    Dr. Pepperberg's research, which uses a training method called the model-rival technique, also holds promise for teaching autistic and other learning-disabled children who have difficulty learning language, numerical concepts and even empathy.

    So far, results using this learning technique with small groups of autistic children have been very promising.

    The latest research work about Alex and his comprehension of zero has been published by the Journal of Comparative Psychology in its May 2005 issue (Volume 119, Issue 2) under the name "Number Comprehension by a Grey Parrot (Psittacus erithacus), Including a Zero-Like Concept." You'll get to the abstract from this page (scroll to number #8).

Scientists are hopeful, but note, "This is the first time that this concept has ever been documented in this particular species of whore, so we still need lots more evidence for the data to be conclusive."

    Another researcher pointed out: "Holand has demonstrated the concept of $0, but we're not sure if he's grasped what he wanted him to, or if he's just hit on related themes like 'The amount of value my posts add to Slashdot'."

    The training of Alex is an experiment which is constantly in progress. This isn't "bad science" but "science in progress."

    It's kind of like condemning an experiment by reading one progress report, decades before the final report is available. And I say decades because Alex is 28 and African Grey parrots can live to be 65+ years old.

    I just saw something last night on Animal Planet on the "Most Extreme" intelligent animals. Parrots were #1, specifically this bird Alex, who has been in training for almost 20 years, I think it is.

    My dad has an African Grey whose name is Max. Max is not as intelligent as Alex, but he demonstrates a limited intelligence. Simple things like saying "come here" when he wants attention or saying "whoops" when he drops a piece of food. It isn't on par with the counting and identifying that Alex can do.

    If you see video of Alex, it's totally amazing. He can identify what objects are made of (wood, metal, wool), he can identify colors (red, blue, yellow, green) and even count up to five--now including zero. He can even flip you attitude: "wanna go sleep" or "wanna go home" or "hungry" -- all in the middle of a training session.

    And it is an incredible animal already without the concept zero. It labels objects by name and properties like color and shape. But also recognize objects which are similar like keys. There is no way for the researcher to hint the solution unconsiously like what happens with the famous counting of horses and dogs (The horse taps the foot X times for the correct answer, but in reality just looks for the right signs in the face or behaviour of the owner (smart too though, sociology (-: )).

    The parrot is in this case better then men in understanding language. The researchers can not talk "parrot language", but this bird can talk human language. What would be great for research if they are able to find out if this parrot has a concept of language and can translate some more familiar environment things (like trees instead of keys) and see if that translates to other parrots in the wild.

    ... to think that you are so advanced you can change your basic behaviour and instincts.

    Face it, you're an omnivore, like it or not. Whether you choose to eat meat or not is irrelevant - you have evolved to eat a variety of foods, including meat. Humankind is the most general of species on this planet - we survive in extreme heat, extreme cold, and everywhere in-between precisely because we can adapt to changing circumstance. Eating meat is a part of this general behaviour. I see no reason to be ashamed of what we do when it's in our nature to do it.

    It may even be (given that it's generally the meat-eaters predatorial requirements for advanced tactics that drive this) that you *had* to eat meat for thousands of years before you'd evolve to the state where it was optional...

    Frankly, those who espouse that we shouldn't eat other animals are mainly hypocrites. Humourous note: while checking the spelling of that, I typed "hypocr" into OSX's dashboard dictionary and it guessed at 'hypocretin'. Although it's not applicable (it's a hormone!), I'd love to adopt it instead of hypocrite. It just fits so well :-)

If you kill the lamb, if you'd rather die, then well and good - I respect your principles whilst simultaneously denouncing you as a fool. If you kill and eat the lamb, everything comes down to a matter of degree - when is it acceptable to eat meat and when is it not?

      While I eat meat myself, I'm not sure I buy your moral logic. If I were starving, I would be willing to steal food. Theft is still wrong. But stealing food is better than starving to death.

      If we're forced into it, sometimes we have to choose the lesser of two evils. But we shouldn't let that choice establish a precedent. We shouldn't say "If it's okay to kill in self defence, then you can kill anyone any time you want as well."

      To a person who believed that an animal has rights, the decision to eat meat would not be a personal one since it would involve another being. The decision to eat meat is only 'personal' if you don't consider the creature being eaten to have rights in the situation.

      The law, of course, recognizes the decision as personal since it only recognizes people as subjects and animals are mostly considered property which is used as people see fit - though there are some animal cruelty laws.

He says hello when we come home or wake him up. He says goodbye when you get your keys to leave the house. He knows how to request that he be let out, fed, pet, and showered. He's practically a child of ours. We jokingly call him our "autistic 5 year old." My wife and I have followed and enjoyed Alex's progress for years.

    I'm not a behavioral science PhD. Yet, How surprising is it that any animal can recognize zero in respect to color? How many yellow fruits are on that green tree? "None, next tree." How many gray mates are there on the brown branches? "None, next area." We have to think that the loser parrots who hung out at the tree with zero fruit didn't do so well in the evolution crap shoot.

    Zero is not so mystically intelligent as we think. Our belly and lungs definitely understand zero. But zero came late to our number systems. Our formalization of zero might well be a mystical leap of intellect, but only history will prove if we are as smart as we think we are. There are a lot of zeros out there we aren't grasping; zero dodos left, zero ozone defense in places, and zero vaccines for modern plagues.

    I look forward to the day when Alex and Mr. Bean learn to solve calculus. Then he can exclaim that the limit of e^x as x approaches infinity is infinity. Negative numbers and imaginary numbers and he'll be doing better than most undergrads.
