Scientists Discover That Horses Can Use Symbols To Talk To Us (sciencemag.org) 171

sciencehabit writes from a report via Science Magazine: Scientists have discovered that horses can learn to use another human tool for communicating: pointing to symbols. They join a short list of other species, including some primates, dolphins, and pigeons, with this talent. Scientists taught 23 riding horses of various breeds to look at a display board with three icons, representing wearing or not wearing a blanket. Horses could choose between a "no change" symbol or symbols for "blanket on" or "blanket off." The horses did not touch the symbols randomly, but made their choices based on the weather. If it was wet, cold, and windy, they touched the blanket-on icon; horses that were already wearing a blanket nosed the "no change" image. But when the weather was sunny, the animals touched the blanket-off symbol; those that weren't blanketed pressed the "no change" icon. The study's strong results show that the horses understood the consequences of their choices, say the scientists, who hope that other researchers will use their method to ask horses more questions. The report has been published in Applied Animal Behaviour Science.

        I don't think that kicking and biting are issues compared to the things people do to horses - slaughtering them for meat or working them for years before sending them to the glue factory.

        • Working them at what? Unless they're racehorses, which is admittedly kind of a horrible industry, they're basically pets for stupidly rich people. Other things people do with horses are hobbies by comparison, and work them about as hard as dog agility training.

Very middle class neighborhood, but on that and a (private school) teacher's salary, they had that and the dad's hobby was sailing, believe it or not. Obviously the horse was boarded somewhere. I vaguely remember that maybe they allowed him to be used for other kid's riding lessons to partially pay for that, but it'

              I'll admit, most horses are owned by people who don't really have any use for them. My younger stepson has two. One was given to him, the other bought at such a low price it might as well have been a gift. In the past year, I've only seen his wife on a horse once, not seen him or the kids astride a horse.

            All over the west, horses do work; they can get to, and through terrain ATV's can't (thus making a mockery of the "all terrain" part), they are very good at assisting in collecting and collaring livestock because they know what the task is, and can operate in concert with from the person sitting them who is trying to rope or herd the animal.

          • Not true.

            Miniature horses are routinely used as service animals, particularly in rural areas (harder to use in a city and they need more outside space).

            They are just as smart, live a lot longer (25-35 years vs.13 on average), and are physically stronger so they can do more work. They do cost more to keep (food, upkeep), and need more space.

            • The food part? Dogs are carnivores. They like meat and meat products. That kind of food is rather expensive. The most expensive feed for horses, miniature or otherwise, would be alfalfa. A miniature probably doesn't eat a lot more than a couple of sheep or goats. Since you don't actually "work" a miniature, you probably aren't going to give him much grain, if any. (added benefit of alfalfa is, it is high protein, very well digested, so there is less waste to deal with)

        These two racehorses were standing in their stable. The first one said, "I've been in 18 races and won 16." The second one said, "That's nothing. I've been in 28 races and won 25." At this point, a greyhound dog walks by, and overhearing the horses, says "I've been in 48 races and won every one of them!"

        Horse:
        Many Muslims (like some Christian sects) consider pictorial representations of the human figure as violating the prohibition on graven images. As with those iconoclastic Christian sects [wikipedia.org] that prohibition is most strictly observed when it comes to religious figures, possibly because of the quasi-worship of Christian saints Muslims witnessed among German knights in the Holy Land, which must have struck them (as it would later Protestants) as a kind of polytheism.

        That's why when you look at the massive, elaborately decorated [google.com] mosques you won't see a single human or animal figure. Instead you'll see elaborate geometrical figures and highly stylized calligraphy, which are the main visual form of Sunni artistic expression. To find any sort of art depicting people one must look to Shia dominated areas, such as Persia (Iran), which boasts many [wikimedia.org] fine [wikipedia.org] examples [pinimg.com].

      While your examples could be simple aggressive behavior in cat culture, they are amusing.

      However, cats indeed use symbolic reasoning. Mine, a mature shelter animal when I got her, loved to play with a boot lace tied off with feathers which I "flew" near her until she realiized it was only a toy controlled by me, at which time she lost interest and did not play anymore.

      However, when she wants my company, she fetches the feathered lace and brings it to me. She does not want to play with it -- she uses it as a symbol to say she wants some face time at the places she hangs out in (the porch or the back room with the sunny exposure.)

      Am I surprised? At first I was, but it looks like Noam Chomsky was right -- we (many creatures) are "hard-wired" for language.

    Hmmm... While it has been shown in a variety of ways going back at least as far as the original Mr. Ed that horses are smart and capable of performing a large repetoire of tricks, I do wonder in this particular case if the horses are touching the symbols at the appropriate times because they understand what the symbols mean, or because they were trained to touch the symbols at the appropriate times. It is a vitally important distinction. Just how did they teach the meaning of each symbol to them without instead accidentally training them to perform without any true understanding of the symbols themselves? Humans have instinctual behaviours towards pattern recognition, anthromorphism, self-delusion, and rationalisation, thus experimential methods must be very carefully designed to remove these influences.

      Humans have instinctual behaviours towards pattern recognition, anthromorphism, self-delusion, and rationalisation, thus experimential methods must be very carefully designed to remove these influences.

      And given that it's been peer-reviewed, the presumption is that they designed their methods to do just that, rather than "peer reviewers in animal behavior aren't aware of the caveats involved in animal studies"

      That doesn't mean 100% that the presumption is correct - peer review is hardly a flawless process.

      Reading over the study, in case you're curious: they discuss the Clever Hans effect, how it manifests (the horse observes the trainer or audience and does what it needs to get a reward based on the audience's reaction). In this study, the trainer was off to the side, out of the field of view of the horse, and they monitored where the horse was looking to ensure it was only looking at the symbols when making its choice. Then the horse was given a reward regardless of what symbol it chose; it simply had to choose one to get a treat. The symbol touches were easy to record and unambiguous, so there was no "interpretation" of the horses behavior in question. The researchers also observed side behaviors. For example, once the horses had learned to use the symbols to control their blanketing status they often became very eager to go into the testing facilitity (before the phase where treats were on offer). It was observed that horses that sought to have their blanket removed in this manner tended to be sweaty underneath it, while those that didn't seek it out weren't.

      To be fair, there's even more that could be done. I really liked the controls that Pepperberg did in her studies of Alex (the African Grey parrot). She had it set up so that the person asking a question didn't know the answer, and neither did the person scoring the result. In this case here, clearly the trainer knew the weather and thus what would be the "optimal" blanketing status. But by paying attention to where the horse's focus is, whether it's hesitating, etc, and giving it a reward either way, I agree that that's some pretty good controlling for the Clever Hans effect.

      • by Anonymous Coward

        If this were "talking" or "communicating", then the horses would have no reason to select any icon when nobody was watching. That they did it even if there was nobody to 'talk to' shows us that it is simple condition response behavior.

        Unless we are claiming the horses are talking to nobody, this is entirely stupid.

      • "In this study, the trainer was off to the side, out of the field of view of the horse, and they monitored where the horse was looking to ensure it was only looking at the symbols when making its choice"

        Yeah, horses have 350 vision, so "off to the side" means the trainer was still in view...

        • by Rei ( 128717 )

          There is of course a difference between being in one's field of vision and being the object focused on, which can be seen by a variety of factors, e.g. where they're pointing their head, their ears, whether there's any hesitation about the action (aka looking for outside cues), etc.

          Clever Hans was an extremely well studied case. The concept that any reviewer is not going to be familiar with it and how to control for it is beyond silly.

        • by Rei ( 128717 )

          If you want the exact wording, it doesn't say "out of the field of view", but "stepped 2-3 meters aside ... standing passive to avoid giving the horse any cues". They later go further into the details of how they monitored the horse's attention and discussion of the Clever Hans effect. They also alter the sides that the different symbols were on to avoid side preferences.

Or is seeing a leash an instinctive reaction in humans that causes them to need to be led by someone smaller than them? That must be it because the little humans never let me walk them when they see the leash.

      Basic single-concept communication seems to be an ability that a wide range of animals are capable of. We seem unusual in our skill at combining concepts.

Merino sheep, for instance, do not understand much at all, relying instead on (1) random variations in behaviour of individuals combined with (2) following those individuals who seem prosperous. But cows are different. Cattle herds are run by the boss cow(s), and cows compete for senior positions using intelligence and/or determination and/or physical intimidation. Some cows are quite smart; most are not that clever. (I understand that elephants can be even smarter.)

      My great grandfather drove a milk wagon. His horses knew all his stops, apparently, and would start off for the next one when he got back in the wagon without any signs from him. I assume that's not as intelligent behavior as what they're testing, but it's still pretty cool. :)
      • by Rei ( 128717 )

        They mentioned in the study related research on teaching horses to navigate mazes. Horses learned the maze at different rates, but they all eventually learned it, and once they learned it they never forgot it, no matter how long it was between maze runs. Seems directly applicable to the "milk route" case.

      • Animals will instinctively learn patterns to gain a reward. What is an order of magnitude more difficult in intelligence is learning a pattern by correlating independent events. e.g. Following a milk truck is easy, picking a symbol based on the current weather and whether or not I'm wearing a blanked requires quite a bit more thought.
