How Your Brain Decides Without You - Issue 19: Illusions Princeton’s Palmer Field, 1951. An autumn classic matching the unbeaten Tigers, with star tailback Dick Kazmaier—a gifted passer, runner, and punter who would capture a record number of votes to win the Heisman Trophy—against rival Dartmouth. Princeton prevailed over Big Green in the penalty-plagued game, but not without cost: Nearly a dozen players were injured, and Kazmaier himself sustained a broken nose and a concussion (yet still played a “token part”). It was a “rough game,” The New York Times described, somewhat mildly, “that led to some recrimination from both camps.” Each said the other played dirty. The game not only made the sports pages, it made the Journal of Abnormal and Social Psychology. In watching and interpreting the game footage, the students were behaving similarly to children shown the famous duck-rabbit illusion, pictured above. I ought not to have felt bad. Attention can “be thought of as what you allow your eyes to look at.” References 1. 2. 3. 4. 5. 6. 7. 8. 9.
35 Scientific Concepts That Will Help You Understand The World, by Aimee Groth In order to sharpen our reasoning skills, we must have a good grasp of our own cognitive biases, as well as the basic laws of the universe. But in a dynamic world, new laws are constantly emerging. The editors over at Edge.org asked some of the most influential thinkers in the world — including neuroscientists, physicists and mathematicians — what they believe are the most important scientific concepts of the modern era. The result is "This Will Make You Smarter: New Scientific Concepts To Improve Your Thinking," a compilation of nearly 200 essays exploring concepts such as the "shifting baseline syndrome" and a scientific view of "randomness." We've highlighted 35 of the concepts here, crediting the author whose essay highlights the theory. Cognitive humility Decades of cognitive research shows that "our minds are finite and far from noble. Cognitive load Our brains can only hold so much information at once.

Michelle Duggar's Most Important Tip for Teaching Kids Manners: Michelle's Blog: TLC Photo: DCL Question from a "19 Kids and Counting" fan on Facebook: I’m dealing with a child that’s in the phase of, “I want. I want. I want.” I sure do. They need to learn that you don’t say, “I want.” I have them do it two or three times, practicing the right way, and then I say, “Sure, you can.” We read a book by S. We also look to Jesus and we want to follow his example when he said, “The greatest among you will be the servant.” This is all that concept of attitude, teaching them that life does not revolve around you.

The 5 Weirdest Sixth Senses Humans Have (Without Knowing It) Every attempt to prove that humans have some kind of telepathic sixth sense shows it to be complete bullshit. But we still shouldn't sell ourselves short -- we have all sorts of "extra" senses that we either never use or don't notice when we do. And some of them come pretty damned close to mind reading. For instance ... #5. Getty In a perfect world, you'd never judge someone until you got to know their personality inside and out -- you know, the whole thing about judging a book by its cover. Getty"You sort of smell like you might wear my skin as a shawl." See, there is a reason you can get a feel for some people before they even say a word: Part of it is the way they smell. Incredibly, the accuracy rate was just as high as when the same participants were asked to gauge people's personalities from watching a video of them. Getty"So what are you in for?" Or maybe we could just sniff the suspects and see which one seems the most nervous. #4. WikipediaStill not seeing the sailboat. #3.
Nine Brain Quirks You Didn't Realize You Had I think the brain is most interesting when it doesn’t work the way you expect it should. Psychology often confirms our intuitions about how our minds work, but it offers quite a few surprises as well. Although some psychology buff’s will have heard a few of these before, here’s a list of quirks in your brain you probably didn’t realize you had: 1) Your short-term memory has a max capacity of seven. Humans have three forms of memory: sensory, long-term and short-term. Remembering information longer than this requires you to either compress it down into seven units or store it in long-term memory. Yellow-green, chartreuse, sits right in the middle of the frequencies of visible light. 3) Your subconscious is smarter than you are. Or at least more powerful. 4) You have two nervous systems. One set controls excitation and the other controls inhibition. 5) Your brain is awful at probability. Okay, so maybe your high-school math teacher could have told you this one.
How Music Hijacks Our Perception of Time One evening, some 40 years ago, I got lost in time. I was at a performance of Schubert’s String Quintet in C major. During the second movement I had the unnerving feeling that time was literally grinding to a halt. The sensation was powerful, visceral, overwhelming. It was a life-changing moment, or, as it felt at the time, a life-changing eon. It has been my goal ever since to compose music that usurps the perceived flow of time and commandeers the sense of how time passes. The human brain, we have learned, adjusts and recalibrates temporal perception. We conceive of time as a continuum, but we perceive it in discretized units—or, rather, as discretized units. In recent years, numerous studies have shown how music hijacks our relationship with everyday time. Also in Music The Necessity of Musical Hallucinations By Jonathan Berger During the last months of my mother’s life, as she ventured further from lucidity, she was visited by music.

The Neuroscience Of "Harry Potter" Let's do a casual experiment. Here's a brief passage from the first book in some obscure fiction series called Harry Potter: A bush on the edge of the clearing quivered. … Then, out of the shadows, a hooded figure came crawling across the ground like some stalking beast. Harry, Malfoy, and Fang stood transfixed. The cloaked figure reached the unicorn, lowered its head over the wound in the animal's side, and began to drink its blood. And here's another passage from the final book of the series: He got up off the floor, stretched and moved across to his desk. Which passage did you find more engaging? The results of our experiment, that action is more engrossing than scene-setting, may be unsurprising. Hsu and collaborators recruited test participants to enter a brain scanner and read passages of Harry Potter (translated into German) about four lines long. The results support what the researchers call the "fiction feeling hypothesis" of reading immersion.
Brain Power: Five Ways Neuroscience Will Change Education Neuroscience isn't just for scientists anymore. The way experts study how children's brains develop over time is influencing classrooms and education overall, and here are the five ways education will begin to change because of it. Neuroeducation will play a key role in the future of education, with curricula based not just on teaching subjects but on preparing brains for learning. YVONNE BERG/OUR KIDS MEDIA Neuroscience is coming to the classroom. Over the last decade, our ability to study how the brain works has dramatically improved. Here are five ways that education will be changed because of what we've learned about a child's brain: 1. In the future, we'll hear a lot about neuroeducation, and we can expect to see curricula based not just on teaching subjects, but on preparing brains for learning.If you think of the brain as a tree with branches, neuroeducation is the process of adding more branches. 2. 3. 4. 5.
Deje que sus hijos viajan en el autobús Alone Most school field trips are to places the students might never go on their own: a museum, a play, a nature preserve. The idea is to open kids wide to the wonderful world. This past spring one grammar school in Silicon Valley started sending kids to a very different, but equally mind-blowing place: their own neighborhood. On their own. Without an adult. The idea was to get children walking around, playing outside, biking to the library—just normal kid stuff. That’s not just sad, it’s a radical new norm: childhood spent under constant adult supervision, and, often enough, in a car. And considering the crime rate today is lower than when most of those parents were growing up—it’s back to the rate it was 40+ years ago—why shouldn’t kids be doing anything on their own? Quick backstory/disclaimer: The project is named for my book and blog, Free-Range Kids, which I began after a column I wrote for The New York Sun—“Why I Let My 9-Year-Old Ride the Subway Alone”—went viral.
"Moving to the beat" improves timing perception | Fiona Manning to half of the blocks (movement condition) and to remain stillduring the other blocks (no-movement condition). Four of the8 trials within each block included an on-time (i.e., at anoffset of 0 ms) probe tone, with the others at one of four offsets: either 30 % or 15 % of the IOI (both early and late).Participants experienced each of the four IOI (400 ms,600 ms) × movement condition (movement, no movement)combinations twice after completing 5 warm-up trials. (i.e., consistent with the repeated se-quence) and indicated their confidence on a scale from 1( not atall confident ) through 5 ( veryconfident ).To helpretainattention, participants received feedback on the correctness of these judgments.

Neuroscience Cannae Do It Cap’n, It Doesn’t Have the Power The brain has hit the big time. Barack Obama has just announced $100 million of funding for the BRAIN Intitiative—an ambitious attempt to apparently map the activity of every neuron in the brain. On the other side of the Atlantic, the Human Brain Project will try to simulate those neurons with a billion euros of funding from the European Commission. And news about neuroscience, from dream-decoding to mind-melding to memory-building, regularly dominates the headlines. But while the field’s star seems to be rising, a new study casts a disquieting shadow upon the reliability of its results. Statistical power refers to the odds that a study will find an effect—say, whether antipsychotic drugs affect schizophrenia symptoms, or whether impulsivity is linked to addiction—assuming those effects exist. But if studies are generally underpowered, there are more worrying connotations beyond missed opportunities. Across the sciences These problems are far from unique to neuroscience.
How Whooshes and Beeps Can Make Babies Better Listeners - The Atlantic A new study says that certain sounds can prime infant brains for language learning. The doctor behind the experiment thinks the technique could greatly reduce auditory and reading disorders. A 9-month-old participant in the Rutgers lab wears a stretchy bonnet with 128 EEG sensors. Can you make your baby smarter? Former Georgia governor Zel Miller thought so. “Having that infant listen to soothing music helps those trillions of brain connections to develop,” he told the state general assembly in Atlanta. “Now don't you feel smarter already?” The budget passed, and, for a few years, new Georgian parents received a free classical recording along with their newborn child. A new study says that some sounds can, in fact, improve a specific type of skill in young children. The study was led by April Benasich, a professor of neuroscience and the director of the Infancy Studies Laboratory at Rutgers University. “But some babies seem to focus on the wrong tier or grain,” she said.
