Language Log

That's the name of a proposed product from the "Nordic Society for Invention and Discovery". It combines two surefire memes, brain waves and dog language,  claiming to be "the first device to translate animal thoughts into human language".

You will have your choice of vocal personalities, with names like "Holly", "Harley", "Pudge", "Mandy", and so on:

There's a video, too.

This is a guest post by Margaret Wilson.

Turn-taking is fundamental to human conversation, so the question of whether it occurs in other social animals is extremely interesting. A new paper on turn-taking in marmoset monkeys (Takahashi et al., "Coupled Oscillator Dynamics of Vocal Turn-Taking in Monkeys", Current Biology, 2013) is to be applauded for tackling this issue.

Unfortunately, though, it is not clear that their data demonstrate turn-taking in any sophisticated sense: specifically (and this is the sense embraced by the authors), entrainment of timing mechanisms between two individuals to regulate the passing of the turn. They begin by asking, "Is this a simple call-and-response (‘‘antiphonal’’) behavior seen in numerous species, or is it a sustained temporal coordination of vocal exchanges as in human conversation?" They conclude that they have shown the latter, but, on my reading, all their data is compatible with simple call-and-response. What seems to be going on is that the authors have failed to appreciate just how weird human turn-taking is.

As we have frequently noted here on Language Log, science stories on the BBC News website are (how to put this politely?) not always of prize-winning standard with respect to originality, timeliness, reliability, or attention to the relevant literature. In fact some of them show signs of being written by kids in junior high school. Way back in 2006 Mark Liberman commented on a BBC News story about the notion that dolphins have and use "names" for each other. He expressed skepticism, but the BBC forged ahead without paying any heed, and today, more than seven years later, we learn from the same BBC site once again that Dolphins 'call each other by name'. Yes, it's the same story, citing the same academic at the University of St Andrews, Dr Vincent Janik. (Mark's link in 2006 was unfortunately to a Google search on {Janik, dolphins}, which today brings up the current stories rather than the ones he was commenting on then.) And you don't need to leave the BBC page to see that the story contradicts itself.

Tim Requarth and Meehan Crist, "From the mouth of babes and birds", NYT 6/29/2013:

Researchers who focus on infant language and those who specialize in birdsong have teamed up in a new study suggesting that learning the transitions between syllables — from “da” to “do” and “do” to “da” — is the crucial bottleneck between babbling and speaking.

“We’ve discovered a previously unidentified component of vocal development,” said the lead author, Dina Lipkind, a psychology researcher at Hunter College in Manhattan. “What we’re showing is that babbling is not only to learn sounds, but also to learn transitions between sounds.”

Thomas Lumley sent in this nice multilingual pun from Sydney, Australia:

Stoeger et al., "An Asian Elephant Imitates Human Speech", Current Biology (2012):

Vocal imitation has convergently evolved in many species, allowing learning and cultural transmission of complex, conspecific sounds, as in birdsong. Scattered instances also exist of vocal imitation across species, including mockingbirds imitating other species or parrots and mynahs producing human speech. Here, we document a male Asian elephant (Elephas maximus) that imitates human speech, matching Korean formants and fundamental frequency in such detail that Korean native speakers can readily understand and transcribe the imitations. To create these very accurate imitations of speech formant frequencies, this elephant (named Koshik) places his trunk inside his mouth, modulating the shape of the vocal tract during controlled phonation. This represents a wholly novel method of vocal production and formant control in this or any other species. One hypothesized role for vocal imitation is to facilitate vocal recognition by heightening the similarity between related or socially affiliated individuals. The social circumstances under which Koshik’s speech imitations developed suggest that one function of vocal learning might be to cement social bonds and, in unusual cases, social bonds across species.

I missed this when it came out — Virgina Morell, "Elephants Have an Alarm Call for Bees", Science Now 4/26/2011:

East Africa’s elephants face few threats in their savanna home, aside from humans and lions. But the behemoths are terrified of African bees, and with good reason. An angry swarm can sting elephants around their eyes and inside their trunks and pierce the skin of young calves. Now, a new study shows that the pachyderms utter a distinctive rumble in response to the sound of bees, the first time an alarm call has been identified in elephants.

… [T]he study suggests that this alarm call isn’t just a generalized vocalization but means specifically, “Bees!” says Lucy King, a postgraduate zoologist at the University of Oxford in the United Kingdom and the study’s lead author.

When they hear buzzing bees, the pachyderms turn and run away, shaking their heads while making a call that King terms the “bee rumble."

For years, the extraordinary ability of parrots to mimic sounds has raised an intriguing but largely unanswered question: what role does this ability play in the wild? This question has been difficult or impossible to study, because most parrots live in dense vegetation and move around a lot, so that no one has been able to get good records of who chirped what to whom, when and under which conditions.

Some recent work makes a start on this problem, as explained by Virginia Morrell, "Why Do Parrots Talk? Venezuelan Site Offers Clues", Science (News Focus) 7/22/2011:

[Below is a guest post by Mark Seidenberg, following up on Geoff Pullum's post "Nim: the unproject", 8/16/2011.]

Nim Chimpsky and I met when I was a graduate student at Columbia. “Project Nim” is an excellent documentary, a deeply sad story leavened with humor and astonishment at the behavior of the personalities involved . The parts of the movie that cover events I observed—the period when Nim lived at the Delafield Mansion in Riverdale NY and was driven down to Columbia for teaching—was accurate as far as it went. It’s a documentary, not a detailed record of what happened, and it is stronger on Nim’s personal history and the foibles of his human caretakers (and I use the term loosely) than on the science.

I was preparing to write a commentary on the movie and the project, but then Peter Singer’s piece appeared in the New York Review of Books ("The troubled life of Nim Chimpsky", 8/18/2011). Singer is the Princeton philosopher famous for “Animal Liberation” and other influential, controversial books. His blog post about Nim got many facts wrong and I was moved to write a short response. It might be of interest to Language Log readers.

Today's SMBC:

The documentary Project Nim, about Herbert S. Terrace's effort to have a chimpanzee reared from birth like a human child and taught sign language, is an excellent piece of film-making, and you should see it. But if you go to it expecting to see something about research and data and results, there's a surprise in store for you. I now think this was not an experiment, there are no results, there is no Project Nim.
