Bibliographical cornucopia for linguists, part 1

Bibliographical cornucopia for linguists, part 1

Since we have such an abundance of interesting articles for this fortnight, I will divide the collection into two parts, and provide each entry with an abstract or paragraph length quotation.

A fundamental question in word learning is how, given only evidence about what objects a word has previously referred to, children are able to generalize to the correct class. How does a learner end up knowing that “poodle” only picks out a specific subset of dogs rather than the broader class and vice versa? Numerous phenomena have been identified in guiding learner behavior such as the “suspicious coincidence effect” (SCE)—that an increase in the sample size of training objects facilitates more narrow (subordinate) word meanings. While SCE seems to support a class of models based in statistical inference, such rational behavior is, in fact, consistent with a range of algorithmic processes. Notably, the broadness of semantic generalizations is further affected by the temporal manner in which objects are presented—either simultaneously or sequentially. First, I evaluate the experimental evidence on the factors influencing generalization in word learning. A reanalysis of existing data demonstrates that both the number of training objects and their presentation-timing independently affect learning. This independent effect has been obscured by prior literature’s focus on possible interactions between the two. Second, I present a computational model for learning that accounts for both sets of phenomena in a unified way. The Naïve Generalization Model (NGM) offers an explanation of word learning phenomena grounded in category formation. Under the NGM, learning is local and incremental, without the need to perform a global optimization over pre-specified hypotheses. This computational model is tested against human behavior on seven different experimental conditions for word learning, varying over presentation-timing, number, and hierarchical relation between training items. Looking both at qualitative parameter-independent behavior and quantitative parameter-tuned output, these results support the NGM and suggest that rational learning behavior may arise from local, mechanistic processes rather than global statistical inference.

The implications of chimpanzee call combinations for the origins of language

The origins of language
Max Planck Institute for Evolutionary Anthropology (May 9, 2025)

Summary:

    Wild chimpanzees alter the meaning of single calls when embedding them into diverse call combinations, mirroring linguistic operations in human language. Human language, however, allows an infinite generation of meaning by combining phonemes into words and words into sentences. This contrasts with the very few meaningful combinations reported in animals, leaving the mystery of human language evolution unresolved.

Birdtalk

As is wont for The New Yorker, this article is long, and it is particularly fascinating, so it is hard to resist quoting many of its more breathtaking revelations:

"How Scientists Started to Decode Birdsong:  Language is said to make us human. What if birds talk, too?"  By Rivka Galchen, The New Yorker (October 14, 2024)

Of course, we've been through the business of animal communication countless times on Language Log, but where this article differs from previous discussions is that it concentrates on content and consciousness rather than vocables and sounds.

On a drizzly day in Grünau im Almtal, Austria, a gaggle of greylag geese shared a peaceful moment on a grassy field near a stream. One goose, named Edes, was preening quietly; others were resting with their beaks pointed tailward, nestled into their feathers. Then a camouflaged speaker that scientists had placed nearby started to play. First came a recorded honk from an unpartnered male goose named Joshua. Edes went on with his preening. Next came a honk that was lower in pitch than the first, with a slight bray. Edes looked up. As the other geese remained tucked in their warm positions, incurious, Edes scanned the field. He had just heard a recorded “distance call” from his life partner, a female goose whom scientists had named Bon Jovi.

Really weird sinographs, part 4: hyena

In "LOL, ROTFL, IJBO" (11/2/23), all the talk of laughter made me think of the epitome of that particular animal behavior, the hyena.  Of all creatures on earth, the hyena is one of the most curious.  Can you imagine going through life laughing at everything, especially when life is so full of tragedy?

Listen:  here, here, here, and there are many other videos and audios of laughing hyenas online.

Hyenas are not members of the dog or cat families. Instead, they are so unique that they have a family all their own, Hyaenidae. There are four members of the Hyaenidae family: the striped hyena, the “giggly” spotted hyena, the brown hyena, and the aardwolf (it's a hyena, not a wolf).

So many words for "donkey"

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":

"The psychology of thinking discretely"

Andrew Gelman, "The psychology of thinking discretely", 10/20/2022:

Sander Greenland calls it “dichotomania,” I call it discrete thinking, and linguist Mark Liberman calls it “grouping-think” (link from Olaf Zimmermann).

All joking aside, this seems like an interesting question in cognitive psychology: Why do people slip so easily into binary thinking, even when summarizing data that don’t show any clustering at all:

It’s a puzzle. I mean, sure, we can come up with explanations such as the idea that continuous thinking requires a greater cognitive load, but it’s not just that, right? Even when people have all the time in the world, they’ll often inappropriately dichotomize. I guess it’s related to essentialism (what isn’t, right?), but that just pushes the question one step backward.

As Liberman puts it, the key fallacies are:

1. Thinking of distributions as points;
2. Inventing convenient but unreal taxonomic categories;
3. Forming stereotypes, especially via confirmation bias.

Does "splooting" have an etymology?

In the summer of 1990, I spent a memorable five weeks at the outstanding summer institute on Indo-European linguistics and archeology held by DOALL (at least that's what we jokingly called it — the Department of Oriental and African Languages and Literatures) of the University of Texas (Austin).  The temperature was 106º or above for a whole month.  Indomitable / stubborn man that I am, I still insisted on going out for my daily runs. 

As I was jogging along, I would come upon squirrels doing something that stopped me in my tracks, namely, they were splayed out prostrate on the ground, their limbs spread-eagle in front and behind them.  Immobile, they would look at me pathetically, and I would sympathize with them.  Remember, they have thick fur that can keep them warm in the dead of winter.

I assumed that these poor squirrels were lying with their belly flat on the ground to absorb whatever coolness was there (conversely put, to dissipate their body heat).  At least that made some sort of sense to me.  I had no idea what to call that peculiar, prone posture.  Now I do.

Cat got your tongue? Or do you have its?

[This is a guest post by Nathan Hopson]

If you’re Japanese, chances are it’s the latter.

Nekojita (猫舌 lit. “cat’s tongue”) is a phrase in Japanese most commonly used to describe people who can’t or don’t like to eat or drink hot things. The word means both the actual tongue itself and, by extension, a person with a cat’s tongue. In other words, it is a synecdoche.

The term is common in Japan, reflecting the fact that many people consider themselves to be/have cat tongues; in a 2018 survey of 10,000 Japanese of all ages, about half described themselves as nekojita. The results are summed up in the accompanying image, in which pink indicates those who answered yes to the question, “Are you nekojita?” As you can see, more than half of 10-49-year-olds consider themselves to have heat-sensitive tongues.

Cat huffing and snorting in Japanese and Chinese

Full disclosure:  I'm not an expert on felines, except sort of for Hello Kitty.  I've owned a lot of dogs, but have never had a kitty kat since the time I was a little boy.  I have a poor understanding of their psychology and behavior, although I very much like to observe them, especially when they're sleeping or sunning themselves, and I love to hear them purr.  Occasionally it's fun to pet them, and I like it when they walk around my legs, twirling / wrapping their tail as they go.

Here's a reddit thread from last fall:

Posted by u/Curious_Cilantro, Oct. 1, 2021

[Chinese] xīmāo 吸猫 – to zone out and enjoy the company of a cat, as if it were a drug. Lit. “snort/suck cat”

Example: After work, I just want to relax at home and xīmāo 吸猫 (enjoy my cat’s company).

It’s a new phrase mostly used by young people. Since snorting drugs is xīdú 吸毒,and cats are so charismatic, appreciating their company is like snorting a drug that helps you relax.

A variation is yún xī māo 云吸猫 (cloud snort cat), which refers to browsing pictures and videos of cats online. A significant portion of reddit is dedicated to accommodating this activity.

[VHM:  Romanizations / Hanyu Pinyin added]

A screenshot of this has been making the rounds on Facebook, shared via the page "Cats on Cocaine" (CokedOutCats), appropriately enough.
