What hunter-gatherer societies can teach us about group decision-making

What hunter-gatherer societies can teach us about group decision-making

Vivek V Venkataraman writes: The Dilemma of the Deserted Husband unfolded in the late 1950s amid a band of G/wi hunter-gatherers, a subgroup of Ju/’hoansi (often known as !Kung San), dwelling in the Kalahari Desert of Southern Africa. According to the South African-born anthropologist and Bushman Survey Officer George Silberbauer, a woman named N!onag//ei had left her husband, /wikhwema, for his best friend. Few were surprised. After all, /wikhwema was a temperamental and pompous man, and a bit of a…

Elephants call each other by name across the savanna

Elephants call each other by name across the savanna

Marta Zaraska writes: Humans have a long history of inventing names for elephants. There is Disney’s Dumbo, of course, and Jumbo, a 19th-century circus attraction, and Ruby, a famed painting elephant from the Phoenix Zoo in Arizona. But new research suggests wild African elephants may pick their own names, too—and use them to call and greet one another on the savanna. Most animals are born with a fixed set of sounds for communication. A few, such as songbirds, can imitate…

Sperm whale clicks could hide a surprisingly complex ‘alphabet’

Sperm whale clicks could hide a surprisingly complex ‘alphabet’

Science Alert reports: A recent analysis of a sperm whale’s vocalizations suggests variations in ‘clicks’ represent a kind of alphabet that forms the basis of a complex communication system. Members of the conservation initiative Project CETI discovered series of clicks less than 2 seconds in length act as codas – basic units (phonemes) of cetacean speech. The highly social mammals have previously been heard identifying themselves with unique patterns of clicking, but this is the first time a combinatorial and…

Spontaneous playful teasing in four great ape species: https://t.co/MhRhkoFPOs @RossanoFederico @IsabelleLaumer @ScienceSquil #ProcB #ethology pic.twitter.com/pzuMbBdTGf — Royal Society Publishing (@RSocPublishing) March 11, 2024 Mongabay reports: Being silly and indulging in humor may sound easy, but our brains need to do a lot of heavy lifting to pull it off. Landing a joke requires recognizing what’s socially acceptable, being spontaneous, predicting how others may react, and playfully violating some social expectations. Until now, research on the complex cognitive abilities that underpin…

How plants communicate with each other when in danger

How plants communicate with each other when in danger

The Washington Post reports: It sounds like fiction from “The Lord of the Rings.” An enemy begins attacking a tree. The tree fends it off and sends out a warning message. Nearby trees set up their own defenses. The forest is saved. But you don’t need a magical Ent from J.R.R. Tolkien’s world to conjure this scene. Real trees on our Earth can communicate and warn each other of danger — and a new study explains how. Injured plants emit…

Unique voice prints in parrots could help birds be recognized in a flock, no matter what they say

Unique voice prints in parrots could help birds be recognized in a flock, no matter what they say

Max Planck Society reports: Parrots are exceptional talkers. They can learn new sounds during their entire lives, amassing an almost unlimited vocal repertoire. At the same time, parrots produce calls so they can be individually recognized by members of their flock—raising the question of how their calls can be very variable while also uniquely identifiable. A study on monk parakeets conducted by the Max Planck Institute of Animal Behavior and Museu de Ciències Naturals de Barcelona might have the answer:…

Unlocking secrets of the honeybee dance language – bees learn and culturally transmit their communication skills

Unlocking secrets of the honeybee dance language – bees learn and culturally transmit their communication skills

A honeybee is performing the waggle dance in the center of this photo to communicate the location of a rich nectar source to its nestmates. Heather Broccard-Bell, CC BY-ND By James C. Nieh, University of California, San Diego The Greek historian Herodotus reported over 2,000 years ago on a misguided forbidden experiment in which two children were prevented from hearing human speech so that a king could discover the true, unlearned language of human beings. Scientists now know that human…

Human noise drowns out communication between dolphins

Human noise drowns out communication between dolphins

The New York Times reports: Mammals in the ocean swim through a world of sound. But in recent decades, humans have been cranking up the volume, blasting waters with noise from shipping, oil and gas exploration and military operations. New research suggests that such anthropogenic noise may make it harder for dolphins to communicate and work together. When dolphins cooperated on a task in a noisy environment, the animals were not so different from city dwellers on land trying to…

The art of active listening

The art of active listening

M M Owen writes: Writing in Esquire magazine in 1935, Ernest Hemingway offered this advice to young writers: ‘When people talk, listen completely… Most people never listen.’ Even though Hemingway was one of my teenage heroes, the realisation crept up on me, somewhere around the age of 25: I am most people. I never listen. Perhaps never was a little strong – but certainly my listening often occurred through a fog of distraction and self-regard. On my worst days, this…

Mushrooms communicate with each other using up to 50 ‘words’, scientist claims

Mushrooms communicate with each other using up to 50 ‘words’, scientist claims

The Guardian reports: Buried in forest litter or sprouting from trees, fungi might give the impression of being silent and relatively self-contained organisms, but a new study suggests they may be champignon communicators. Mathematical analysis of the electrical signals fungi seemingly send to one another has identified patterns that bear a striking structural similarity to human speech. Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae – similar to how nerve cells transmit…

I’m not sorry for my delay

I’m not sorry for my delay

Joe Pinsker writes: At first, being reachable all the time felt good. To professionals who started using BlackBerries 20 years ago to conduct business on the go, it registered as a superpower. “They felt like masters of the universe,” Melissa Mazmanian, an informatics professor at UC Irvine who studied the devices’ uptake in the early 2000s, told me. But as more people got mobile devices, responding to messages anytime became the norm among co-workers as well as friends and loved…

The garbage language that makes business sound as though it’s running well

Molly Young writes: I worked at various start-ups for eight years beginning in 2010, when I was in my early 20s. Then I quit and went freelance for a while. A year later, I returned to office life, this time at a different start-up. During my gap year, I had missed and yearned for a bunch of things, like health care and free knockoff Post-its and luxurious people-watching opportunities. (In 2016, I saw a co-worker pour herself a bowl of…

The psychology of Greta Thunberg’s climate activism

The psychology of Greta Thunberg’s climate activism

Scott Koenig writes: In September 2019, Greta Thunberg, the Swedish teenage activist, excoriated world leaders for their ongoing failure to address the climate crisis. “You have stolen my dreams and my childhood with your empty words,” she said at one point during her speech at the United Nations. Thunberg has been galvanizing public support for climate action since rising to prominence with her school strike about a year ago, and her latest remarks are no exception. They’ve attracted millions of…

Maybe the differences between human and non-human animals are not as great as we might previously have thought. from www.shutterstock.com By Scarlett Howard, Université de Toulouse III – Paul Sabatier; Adrian Dyer, RMIT University, and Andrew Greentree, RMIT University Most children learn that written numbers represent quantities in pre-school or junior primary school. Now our new study shows that honeybees too can learn to match symbols and numerosities, much like we humans do with Arabic and Roman numerals.

Green monkeys borrow vervet monkeys’ eagle warning call when threatened by drones

Green monkeys borrow vervet monkeys’ eagle warning call when threatened by drones

Smithsonian.com reports: Some 40 years ago, scientists discovered that East African vervet monkeys (Chlorocebus pygerythrus) produce distinct alarm calls when they encounter their three main predators: leopards, snakes and eagles. Their cousins in West Africa, green monkeys (Chlorocebus sabaeus), are also known to cry out at the sight of leopard and snakes, but for some unknown reason, they don’t seem to emit a unique call for birds of prey. A team of researchers recently discovered, however, that the sight of…

The empathetic humanities have much to teach our adversarial culture

The empathetic humanities have much to teach our adversarial culture

Comments 0 Comment

By Alexander Bevilacqua, Aeon, January 15, 2019 As anyone on Twitter knows, public culture can be quick to attack, castigate and condemn. In search of the moral high ground, we rarely grant each other the benefit of the doubt. In her Class Day remarks at Harvard’s 2018 graduation, the Nigerian novelist Chimamanda Ngozi Adichie addressed the problem of this rush to judgment. In the face of what she called ‘a culture of “calling out”, a culture of outrage’, she asked…
