Abstract thoughts prompt literal physical response

Beth Kelley

From New York Times:

Researchers at the University of Aberdeen found that when people were asked to engage in a bit of mental time travel, and to recall past events or imagine future ones, participants’ bodies subliminally acted out the metaphors embedded in how we commonly conceptualized the flow of time.
As they thought about years gone by, participants leaned slightly backward, while in fantasizing about the future, they listed to the fore. The deviations were not exactly Tower of Pisa leanings, amounting to some two or three millimeters’ shift one way or the other. Nevertheless, the directionality was clear and consistent.
“When we talk about time, we often use spatial metaphors like ‘I’m looking forward to seeing you’ or ‘I’m reflecting back on the past,’ ” said Lynden K. Miles, who conducted the study with his colleagues Louise K. Nind and C. Neil Macrae. “It was pleasing to us that we could take an abstract concept such as time and show that it was manifested in body movements.”
The new study, published in January in the journal Psychological Science, is part of the immensely popular field called embodied cognition, the idea that the brain is not the only part of us with a mind of its own.
“How we process information is related not just to our brains but to our entire body,” said Nils B. Jostmann of the University of Amsterdam. “We use every system available to us to come to a conclusion and make sense of what’s going on.”
Research in embodied cognition has revealed that the body takes language to heart and can be awfully literal-minded.

Monkey calls translated

Beth Kelley

Reported by Nicolas Wade, NYT:

Walking through the Tai forest of Ivory Coast, Klaus Zuberbühler could hear the calls of the Diana monkeys, but the babble held no meaning for him.

Today, after nearly 20 years of studying animal communication, he can translate the forest’s sounds. This call means a Diana monkey has seen a leopard. That one means it has sighted another predator, the crowned eagle. “In our experience time and again, it’s a humbling experience to realize there is so much more information being passed in ways which hadn’t been noticed before,” said Dr. Zuberbühler, a psychologist at the University of St. Andrews in Scotland.

Do apes and monkeys have a secret language that has not yet been decrypted? And if so, will it resolve the mystery of how the human faculty for language evolved? Biologists have approached the issue in two ways, by trying to teach human language to chimpanzees and other species, and by listening to animals in the wild.
The first approach has been propelled by people’s intense desire — perhaps reinforced by childhood exposure to the loquacious animals in cartoons — to communicate with other species. Scientists have invested enormous effort in teaching chimpanzees language, whether in the form of speech or signs. A New York Times reporter who understands sign language, Boyce Rensberger, was able in 1974 to conduct what may be the first newspaper interview with another species when he conversed with Lucy, a signing chimp. She invited him up her tree, a proposal he declined, said Mr. Rensberger, who is now at M.I.T.

But with a few exceptions, teaching animals human language has proved to be a dead end. They should speak, perhaps, but they do not. They can communicate very expressively — think how definitely dogs can make their desires known — but they do not link symbolic sounds together in sentences or have anything close to language.

Better insights have come from listening to the sounds made by animals in the wild. Vervet monkeys were found in 1980 to have specific alarm calls for their most serious predators. If the calls were recorded and played back to them, the monkeys would respond appropriately. They jumped into bushes on hearing the leopard call, scanned the ground at the snake call, and looked up when played the eagle call.

Mummies had clogged arteries

Beth Kelley2 Comments

A recent study of mummies found a significant number of the elite mummies (which most were) had clogged arteries, calcification of vessels, and other symptoms of heart disease and obesity.

This has been found before, but this is the largest study so far.

The BBC article I read suggested it was caused by the supposed large amounts of fatty meats being eaten by the elite.

However, as I suspected he might, Rafe said “There’s currently a bit of discussion on GNXP (Gene Expression). Michael Eades, auther of Protein Power, has published in the past showing that the Egyptian elite were in fact obese quite regularly, and attributes it to a diet that was very high in grains combined with a sedentary lifestyle, not the high in meat diet proposed in the BBC article.”

Quoted from Science Daily: “UC Irvine clinical professor of cardiology Dr. Gregory Thomas, a co-principal investigator on the study, said, ‘The findings suggest that we may have to look beyond modern risk factors to fully understand the disease.'”
