Study: Elephants Have Learned To Tell Certain Languages Apart

Posted by samzenpus on from the I-think-he-can-hear-you-ray dept.

sciencehabit writes "Whether we realize it, African elephants are listening to us. The pachyderms can tell certain human languages apart and even determine our gender, relative age, and whether we're a threat, according to a new study. The work illustrates how elephants can sometimes protect themselves from human actions. The work may be helpful in preventing 'human-elephant conflicts where the species co-exist,' says Joshua Plotnik, a behavioral ecologist at Mahidol University, Kanchanaburi, in Thailand. For instance, elephants might be deterred from entering farmland or encouraged to stick to the corridors designed for their use. 'The trouble is elephants are too smart to be fooled by us for long.'"

      Probably the same distinction all sorts of co-habitating animals of different species make when distinguishing between, say, the chattering of harmless monkeys or jungle birds versus the growl of a predatory animal. It makes sense to me, since it seems like the ability to distinguish between animal languages (or even different types of sounds within the same species language) would be a valuable evolutionary trait.

      I'd be surprised if they could distinguish fine accents. If you gauge your own ability, you can typically tell when people are speaking different *major* languages, but not between regional differences of the same language, for instance. Or, very closely-related languages are also hard to distinguish for most people. I'd be surprised if elephants were able to distinguish any better than us.

      Dogs read our emotions by looking at our facial expressions and other body language. They can then associate those with the words we use. It might seem like the dog understands what we say, but it's just Pavlov up to his old tricks.

      Maybe the elephants use a similar mechanism. Their memories are outstanding, so it doesn't seem unreasonable that they simply remember specific people very well and can determine their intentions by body language. Couple that with a recollection of what that person was saying (and what it sounded like) and the elephant then appears to understand differences between languages when what is really happening is they've simply been conditioned to have that response based on a sound being similar to the guy that tried to spear them previously.

      I have little idea what a tiger is trying to communicate when it makes sounds, nor do I have much of an idea what a lion is trying to communicate. But if you expose me to some tigers that try to kill me, chances are I will remember what that sounded like later and I'll be able to distinguish the difference between a lion and a tiger.

      Elephants are big business in India. They are trucked all the way from East (Assam) to the South (Kerala) in India. The only problem is that these places speak different languages. Usually elephants can obey pretty detailed commands like "pick this palm frond from here and carry it home with you" (so that they can be fed), based on the tone of the voice. It is extremely common for transported elephants to get confused and run amok.
      Even worse, elephants in Assam are taught to frolic in water, while in Kerala they are bathed by mahouts. Results in utter confusion when an Assamese elephant goes to a crowded bathing ghat and starts jumping about, with the mahouts running behind the elephant with scrubbers in their hands.

      Maasai is a Nilotic language and Kamba is a Bantu language, so they are as distant as English and Maasai. I think we should also consider prosody as a candidate for the feature that elephants use to distinguish languages. Like phonology, prosody is about sounds, but it's about the rhythm and stress of the language, rather than the individual sounds (which is actually phonetics, not phonology) and their relationship to one another (phonology).

      I think relatively close languages could have very pretty different sound inventories and prosody, so I wouldn't be surprised if they could still make the distinction. Obviously, exposure to at least one of the two languages would likely be necessary to allow for distinction. A lot of humans can't distinguish between two languages that they're not very familiar with and definitely not between two accents of the same unfamiliar language, although who is to say that elephants are not better at this than humans are. Language is a skill humans are wired for, but I'm not sure if distinguishing between two languages, unless one of them is your own, is something that people are particularly good at.

      I'd be interested in knowing if the elephants are using parts of their brain that are involved in elephant communication to perform this task or whether they are just using their general auditory skills.
