Non-Human Language: Evidence Now?

The Nova documentary Ape Genius showed some pretty remarkable footage of a bonobo named Kanzi who appeared to show some remarkable linguistic ability, including following complex instructions in English without non-verbal cueing.

According to the documentary, Kanzi learned to understand English, to a limited extent, without formal training.

What Kanzi was doing in the film was more complex than, say, what a dog does when we say "Go get your ball".

Kanzi was able to discern subject and object, for instance, and understand purely verbal directional cues.

If this is legit -- and it seemed to be -- this is a tremendous breakthrough.

I've openly criticized much of the previous non-human language experiments with primates on this forum.

But this appears to be a whole nother ball of wax.

Still, I've been out of the field for some years now.

Can anyone here shed more light on the research, the researchers, etc.

For the first time, I'm thinking, wow, we may have a really important new insight here.

Sorry, meant to get back to you earlier on this.

Yes, I'm familiar with this stuff. The researcher is Sue Savage-Rumbaugh (whom I've met; nice person, and a good speaker) and she did most of her research at the Yerkes Center in Atlanta, GA, but I think she's now at some new red-state primate zoo in the middle of the US.

I think her work is good, but it's (ahem) controversial. The basic problem is the Clever Hans effect (how do you know that she's not cuing Kanzi to do what she wants?) and the reverse (how do you know that she's not overinterpreting meaningless gestures?)

There's a fairly good book by Sue herself (biased, of course) called Kanzi : The Ape at the Brink of the Human Mind. Personally, I find the Kanzi data to be superficially compelling, but I've never interacted with Kanzi himself, which makes it very difficult for me to have an informed opinion. Remember the problems with the Terri Schiavo videos a while back? Take that interpretation problem, multiply it by a bajillion, square it, and come back to me.....
 
The basic problem is the Clever Hans effect

My thoughts, as well.

The mask, while bizarre, mitigated against a CHE, but certainly can't be said to eliminate it.

The complexity of the tasks also pointed to a real understanding of subject, object, etc.

But I would have liked to have seen, for example, variations on the commands, such as putting the keys "on" the refrigerator or "beside" the refrigerator in addition to "in" the refrigerator.

The "Clever Hans" effect isn't a facor in regard to Kanzi as he regularly recieves commands through earphones given to him by people who are not his daily trainers.

Interesting.

If you have any easily accessible resources to cite, please let me know.

I'd be very interested in reading a lot more about this case.

Thanks.
 
Can I just cut and paste all the work I did providing sources on this from the other 2 threads? ;)

Clever Hans is an old research error that is not committed anymore by legit researchers. That's why in the NOVA program when the researcher told the chimp (or bonobo, I've forgotten) to get something from outside and put something in the fridge she wore a wielder's helmut covering her face.

It's an excellent thread. My posts start here:

I think Piggy was correct in his observations on Penny and Koko, but those were poor examples of research. And the errors like Clever Hans have been identified and corrected over 30 years of research. That was something for whatever reason Claus could not get a handle on. In addition, revelations about the window of opportunity for language acquisition in humans led to the changes in the direction of language research in non-human primates.

And better observations are leading us to discover the language used by primates, dolphins and whales, elephants, and the body language of horses and dogs. It is interesting a dog knows many human verbal commands. Only recently have we started recognizing animal languages to the extent we understand them.

Thanks, skeptigirl!

It wasn't unusual for the folks in the "we haven't seen it yet" camp to be criticized as absolutists, but our beef was -- as you say -- with the quality of the research and evidence, rather than any pre-held belief that humans must necessarily be unique in the world.

I think everyone in the field -- and even ex-pats like me -- will be truy excited if we get some genuine new findings that change our thinking.

I do wonder if the choice of species is important. Bonobos, of course, are famous for having a more cooperative and less aggressive culture than chimps, so perhaps that plays into it.

I'm changing jobs right now, so it will probably be a few weeks before I can follow up on all the cites, including the print book referenced by drkitten, but I'm looking forward to it.

You are welcome. I actually appreciated your original post on Koko as I had not realized how poor that research was until then.

The research you want to look at is Keeli an Ivy and their clan. Those were primates taught language since birth. That made a significant difference.
 
Now skeptigirl, please explain the term "wielder's helmut" in human language.:p
 
Did I post a faux pas?

Ooops, welder's helmet. Wonder why spell check missed it?

Wielder - usually if you put an apostrophe in a word like that spell check doesn't like it.
