If You’re Happy and You Know It, Baby Knows It Too. It may seem like infants are tiny blobs of burps and poop -- but research is beginning to show how babies understand emotional states, from scary faces to threatening barks and sad music. Ross Flom, professor of psychology at Brigham Young University, has looked at emotional affect and babies over a wide variety of settings.
“You and I went through more development in the first two years of life than we'll ever experience at any other point in time in our life,” says Flom. “So, in order to study development we need to understand babies.” Infants are communicative from birth, through cries that signal they want to be picked up, they’re bored, or they’re hungry. Flom says he wanted to know how that communication process develops, and one way is through the sharing of emotion (also known as affect). “Affect is probably most easily shared form of communication between infant and adult,” says Flom – one that is shared through faces, bodies, and also through animals. FYI: What Is The Evolutionary Purpose Of Tickling? You probably know that you can't tickle yourself. And although you might be able to tickle a total stranger, your brain also strongly discourages you from doing something so socially awkward. These facts offer insight into tickling's evolutionary purpose, says Robert R.
Provine, a neuroscientist at the University of Maryland, Baltimore County, and the author of the book Laughter: A Scientific Investigation. Tickling, he says, is partly a mechanism for social bonding between close companions and helps forge relationships between family members and friends. Laughter in response to tickling kicks in during the first few months of life. Children enthusiastically tickle one another, which some scientists say not only inspires peer bonding but might help hone reflexes and self- defense skills. Tickling while horsing around may have also given rise to laughter itself. In adulthood, tickling trails off around the age of 40. Everything You've Ever Been Told About How You Learn Is A Lie. How We Remember To Remember. "Remind me not to forget…" I often say to my roommate. My phone charger. The sandwich I made to take to work.
The bill I need to put in the mail. The way our brain handles remembering to remember something, called prospective memory, has been somewhat of a mystery to scientists. If you really don't want to forget something as you leave the house, put it by the door.Researchers from Washington University in St. The participants showed different patterns of brain activation depending on what they were trying to remember. When the target in question was only a syllable something that had nothing to do with categorizing words ("tor"), the participants had to constantly remind themselves to push the target button. By contrast, when the target was a full word like "table"--similar to the words participants were already seeing as part of the categorization task--the participants weren't forced to pay attention so rigorously.
Why Humans Are Bad at Multitasking | Psychology & Human Behaviors. It may not be uncommon to see someone typing out an email on their phone as they walk down the street, listen to music as they read the newspaper on the subway, or stare at a computer screen with multiple windows and tabs open. But despite constantly juggling different activities, humans are not very good at multitasking, experts say. Dividing attention across multiple activities is taxing on the brain, and can often come at the expense of real productivity, said Arthur Markman, a professor in the department of psychology at the University of Texas at Austin.
"There's a small number of people who are decent multitaskers — this concept of a 'supertasker' — but at best, it's maybe 10 percent of the population, so chances are, you're not one of them," Markman told LiveScience. "The research out there will tell you that there are a couple of people who are good at it, but it's probably not you. " Day-to-day distractions Time-sharing the brain Force of habit. Here's the Real Reason Why Virtual Reality Doesn't Work Yet. You must have not read the article and are totally missing the point, but nice try defending the rift, which is doomed to be forgotten. ;) You're forgetting proprioception (the 6th sense everyone misses when they say we only have five sense). No, I read the article. I just think the premise is flawed, at least as it pertains to people.
Rats and other non-human mammals have a whole suite of senses that help form their impression of "place" in a different way than humans do. We depend much more heavily than most mammals on visual stimulus, and I would bet that this extends to our encoding of spatial data. It would be interesting to see how an analogous experiment, performed on humans, would come out, is all I'm saying. Also, why the Rift-bashing? I mentioned proprioception specifically, in my comment. :) Why We Can't Stop Eating Frosting From The Can. You know when you're eating frosting straight out of the can and you're thinking, "I don't even really like this flavor," but you keep on eating?
(It's a dark, but human, moment. We understand.) Well, now one study is offering an explanation for why. Compared to calorie-free foods, foods with calories in them hit the human brain with big effects, even if people don't appear to consciously like the flavors all that much. There appear to be two unrelated brain circuits that kick into gear when people consume things, Dana Small, a Yale University psychologist who studies people's responses to food and one of the scientists who performed this study, tells Popular Science. There's one that's related to consciously liking flavors. And then there's another that responds to glucose in the blood, which is an indicator of that person's metabolism of food.
Over time, animals learn to prefer mixtures containing real sugar instead of artificial sweetener. Об ошибках и парадоксах мышления. Султан выбирал жену. Каждую кандидатку в жены он спрашивал: сколько будет 2х2? Первая ответила, что будет «четыре». Умная – отметил султан. Вторая ответил, что не разбирается в счете. Скромная – отметил султан. Третью ответила, что будет столько сколько сиятельству будет угодно.
Преданная – отметил султан. Ту, у которой задница больше. Мы постоянно сталкиваемся с иллюзиями. Рис. 1.

Curiouser and curiouser: Curiosity beams back high-resolution zooms of Mars. Cross-posted from Scientific American. Like an adventurer of old, NASA’s Curiosity rover is using its spyglass to scope out some as-yet unexplored environs. The image above comes from Curiosity’s 100-millimeter telephoto camera, which, according to NASA, has about three times the resolving power of any previous landscape camera deployed on the Red Planet. The literally otherworldly landscape has been colorized both for visual appeal and to highlight geologic differences in the soil types. “It’s probably a little bit more pastel and pinker than it would be to your eye,” geologist Mike Malin said during a 27 August press briefing.
His company, Malin Space Science Systems, built four of the cameras for the rover mission, including the Mars Descent Imager that documented Curiosity’s landing in high-res color. What is this thing called love? Mere chemical trickery. Kayt Sukel, contributor In The Chemistry Between Us, neuroscientist Larry Young and journalist Brian Alexander examine the neurobiological roots of love THERE is a reason most of us sigh into our drinks when Cole Porter croons, "What is this thing called love? " We understand his befuddlement all too well. (And let's face it: if a man about town like Porter couldn't figure out this whole love thing, what hope is there for the rest of us mere mortals?) That's why it is encouraging to know that in the past two decades social neuroscientists have been diligently working to unravel the mysteries of love - including the phenomena of attraction, monogamy and the parent-child bond - using techniques such as brain imaging, genome-wide association studies and transgenic animal models.
A few recent books, including my own, Dirty Minds, have chronicled love and sex-related efforts in neuroscience. Still, the authors don't back down. His And Hers Colors – Men, Women, And Two Thousand Color Names. Picture a happy couple – let’s call them Dick and Jane – out furniture shopping. They happen upon a comfy couch with pink upholstery, and Jane wants to buy it. Whether that puppy glides out the front door, or lingers on the showroom floor, could depend upon the words she uses to describe it. For maximum male appeal, should Jane call her sofa “light red?”
“Husky salmon?” Right now, Jane needs a gender-color thesaurus… but in lieu of such exoticness, she might sample the cushy charms of the latest model in our fine line of well-built data visualizations, entitled His And Hers Colors: His And Hers Colors. Update, 18 Sep 2012: We’ve replaced the original visualization with a new-and-improved version. That’s a dot for each of the 2,000 most commonly-used color names as harvested from the 5,000,000-plus-sample results of XKCD’s color survey, sized by relative usage and positioned side-to-side by average hue and vertically by gender preference.
But don’t fret, dudes. Подсознание и плацебо. DOES root canal surgery feel more painful because you can hear the dentist's drill? That is one implication of new research suggesting that sounds, sights and smells can subtly alter our response to treatment, in a way akin to the placebo effect. The finding reinforces the idea that much of our behaviour may be the result of our minds responding subconsciously to cues that are reminders of past experiences. The placebo effect occurs when people with a medical condition appear to get better after receiving a treatment containing no active ingredients - for example, sugar pills - or even after a chat with a kindly doctor.
It is thought to work because recipients have, over their lifetime, become conditioned to feel better when they take a pill or see their doctor. It had been thought that the effect only occurs when we are conscious of receiving treatment. Next, 20 of the participants repeated the test, but this time the researchers applied the same level of heat for both images. (YouTube) Страх и поведение.
Как работает Плацебо. ON THE face of it, the placebo effect makes no sense. Someone suffering from a low-level infection will recover just as nicely whether they take an active drug or a simple sugar pill. This suggests people are able to heal themselves unaided - so why wait for a sugar pill to prompt recovery? New evidence from a computer model offers a possible evolutionary explanation, and suggests that the immune system has an on-off switch controlled by the mind.
It all starts with the observation that something similar to the placebo effect occurs in many animals, says Peter Trimmer, a biologist at the University of Bristol, UK. For instance, Siberian hamsters do little to fight an infection if the lights above their lab cage mimic the short days and long nights of winter. Likewise, those people who think they are taking a drug but are really receiving a placebo can have a response which is twice that of those who receive no pills (Annals of Family Medicine, doi.org/cckm8b). More From New Scientist. Humans Can't Be Empathetic And Logical At The Same Time. Logic and emotion tend to be considered as polar opposites. Think about the analytic CEO—his actions make sense in the science of profit, but when it means using cheap human labor or firing a couple hundred employees, there's an apparent lack of concern for the human consequences of his actions. Many choices are a struggle to compromise the two systems--and that may have to do with how our brains are wired.
A new study published in NeuroImage found that separate neural pathways are used alternately for empathetic and analytic problem solving. The study compares it to a see-saw. Anthony Jack, an assistant professor in cognitive science at Case Western Reserve University and lead author of the study, relates the idea to an optical illusion. The study took magnetic resonance images of 45 college students as they were presented with problems involving social issues or physics. Our brain can do unconscious mathematics - life - 13 November 2012.
What is nine plus six, plus eight? You may not realise it, but you already know the answer. It seems that we unconsciously perform more complicated feats of reasoning than previously thought – including reading and basic mathematics. The discovery raises questions about the necessity of consciousness for abstract thought, and supports the idea that maths might not be an exclusively human trait Previous studies have shown that we can subliminally process single words and numbers. To identify whether we can unconsciously perform more complicated processing, Ran Hassin at the Hebrew University of Jerusalem, Israel, and his colleagues used a technique called continuous flash suppression. The technique works by presenting a volunteer's left eye with a stimulus – a mathematical sum, say – for a short period of time, while bombarding the right eye with rapidly changing colourful shapes.
In the team's first experiment, a three-part calculation was flashed to the left eye. More From New Scientist.
