Language Log

In yesterday's "AI deception?" post, I proposed that we ought to apply to AI an analogy to the philosophical evaluation of "theory of mind" issues in animals. And one of the clearest presentations of that evaluation is in Daniel Povinelli,  Jesse Bering, and Steve Giambrone, "Toward a science of other minds: Escaping the argument by analogy" (2000). You should read the whole thing — and maybe look through some of the many works that have cited it. But today I'll just present some illustrative quoted passages.

Noor Al-Sibai, "AI Systems Are Learning to Lie and Deceive, Scientists Find", Futurism 6/7/2024:

AI models are, apparently, getting better at lying on purpose.

Two recent studies — one published this week in the journal PNAS and the other last month in the journal Patterns — reveal some jarring findings about large language models (LLMs) and their ability to lie to or deceive human observers on purpose.

Sino-Platonic Papers is pleased to announce the publication of its three-hundred-and-forty-sixth issue: "The Imagery of House Geckos and Tokay Geckos in Imperial Era Chinese Literature," by Olivia Anna Rovsing Milburn.

For as long as I can remember, I've been aware that whales, dolphins, porpoises, and other large mammals of the seas (the cetaceans) make whistles, clicks, calls, groans, songs, and other sounds / noises.  These vocalizations are manifestly complex and nuanced, leading people to believe that they are communicating content, emotions, and so forth.  What exactly they are conveying and how they do it have remained a mystery, but researchers never stop trying to figure out cetacean "language".  A new study at MIT claims to have made progress in analyzing sperm whale sound systems.

Scientists document remarkable sperm whale 'phonetic alphabet'

I was hesitant to read this article at all because of the mention of a "phonetic alphabet".  Even with the quotation marks around it, attributing this ability to sperm whales was a bit much for me.

Yet, since it was "scientists" doing the documenting, I forced myself to read the first two paragraphs:

Get ready!  They're coming, and they will make a huge amount of shrill, raucous NOISE.  They are most prevalent in the eastern half of the United States on a rolling basis for different regions, but this year, they will be positively overwhelming in the corridor from Northern Illinois to Arkansas and thence along the Southeast mountainous band stretching up to Virginia.

"Where billions of cicadas will emerge this spring (and over the next decade), in one map:  Cicadas will hear the call of spring. And then you’ll hear their mating calls, too."  By Brian Resnick, Vox.com (1/23/24)

For 17 years, cicadas do very little. They hang out in the ground, sucking sugar out of tree roots. Then, following this absurdly long hibernation, they emerge from the ground, sprout wings, make a ton of noise, have sex, and die within a few weeks. Then, their orphan progeny return to the ground and live the next 17 years in silence. Rarer are the 13-year cicadas, which do the same, but in a little more of a hurry — spending just 13 years underground.

Or, what makes a turtle a dove?

When I was teaching at Tunghai University from 1970-72, naturally I spent the bulk of my time in Taichung ("Tai Central"), but I would regularly visit my in-laws in Taipei ("Tai North"), 160 km to the north.  They lived in a part of the city that was situated midway between National Taiwan University and Taiwan Normal University, where there were still many grand, old, wooden Japanese-style houses.

There were lots of memorable happenings in those neighborhoods, but one which struck me to the core is when people who raised flocks of pigeons would let them out for a spin, so to speak.  The pigeons — a dozen or so (?) — would whir out of their dovecotes and flutter off into the sky in ever distancing gyres.  I would stand on the fourth floor roof of our new reinforced concrete building (the first in that part of the city) and watch them as long as I could.  Usually, however, I would lose track of them after several minutes.  Eventually, the flock would miraculously return and settle down on their perches and in their nests, cooing contentedly.

Those whale vowels are on my to-blog list. But for now, please remember that talking animals can be dangerous — at least, this evening:

Lauren Scott & Brittany Florkiewicz, "Feline Faces: Unraveling the Social Function of Domestic Cat Facial Signals", Behavioral Processes 2023:

ABSTRACT: Lately, there has been a growing interest in studying domestic cat facial signals, but most of this research has centered on signals produced during human-cat interactions or pain. The available research on intraspecific facial signaling with domesticated cats has largely focused on non-affiliative social interactions. However, the transition to intraspecific sociality through domestication could have resulted in a greater reliance on affiliative facial signals that aid with social bonding. Our study aimed to document the various facial signals that cats produce during affiliative and non-affiliative intraspecific interactions. Given the close relationship between the physical form and social function of mammalian facial signals, we predicted that affiliative and non-affiliative facial signals would have noticeable differences in their physical morphology. We observed the behavior of 53 adult domestic shorthair cats at CatCafé Lounge in Los Angeles, CA. Using Facial Action Coding Systems designed for cats, we compared the complexity and compositionality of facial signals produced in affiliative and non-affiliative contexts. To measure complexity and compositionality, we examined the number and types of facial muscle movements (AUs) observed in each signal. We found that compositionality, rather than complexity, was significantly associated with the social function of intraspecific facial signals. Our findings indicate that domestication likely had a significant impact on the development of intraspecific facial signaling repertoires in cats.

The sound of a cat's purr is a familiar one:

But this familiar sound raises at least two interesting biophysical questions.

In the first place, cats purr both while breathing out and breathing in, while most people can only produce voiced sounds (= laryngeal oscillations) while breathing out. What do cats have or do that we don't have or do?

In the second place, cats' purring is much lower in pitch than we'd expect given their size.

Even North America’s Elk Have Regional Dialects

Why do Pennsylvania elk sound different from Colorado elk?

By Kylie Mohr, The Atlantic Monthly (July 16, 2023)

—–

It’s a crisp fall evening in Grand Teton National Park. A mournful, groaning call cuts through the dusky-blue light: a male elk, bugling. The sound ricochets across the grassy meadow. A minute later, another bull answers from somewhere in the shadows.

Bugles are the telltale sound of elk during mating season. Now new research has found that male elks’ bugles sound slightly different depending on where they live. Other studies have shown that whale, bat, and bird calls have dialects of sorts too, and a team led by Jennifer Clarke, a behavioral ecologist at the Center for Wildlife Studies and a professor at the University of La Verne, in California, is the first to identify such differences in any species of ungulate.

Animal communication is not a favorite topic here at Language Log, but according to the following account, one project concerning it seems serious and is being conducted by credible scientists.  Although their claims for its ultimate significance may be inflated, I believe the research they are undertaking is worth considering, especially after hearing the clicks and codas of the sperm whales, which do appear to be communicating data.

Can Understanding Whale Speech Help Us Talk to Aliens?

Biologist David Gruber thinks decoding the language of whales could be just the first step in understanding what other lifeforms are saying—in this world and out of it.

Almost as many as Eskimo words for "snow".  (hee-hee haw-haw) (see below for a sampling)

I've always been a great admirer of donkeys, and I love to hear them bray and make all sorts of other expressive sounds, some of which I am incapable of adequately expressing in words — especially when they are being obdurately stubborn and are unwilling to move, no matter what.  Anyway, their vocabulary extends way beyond the basic "hee-haw":
