Inattentional blindness: Moon-walking Gorilla in the Brain

Have you ever wondered why you usually miss glaring bloopers in major motion pictures? If you are like most people, you probably believe that just because your eyes are open, you are seeing. So why do we sometimes fail to see things that are right in front of our eyes?

The reality is that attention plays a major role in visual perception. One of the primary reasons why you fail to notice these mistakes in films and television programs is a psychological phenomenon known as inattentional blindness. When your attention is focused on one demanding task, such as paying attention to the main character in a movie, you might not notice unexpected things entering your visual field.

The “left – right brain” Myth

We wrote about the 10% brain myth last month and subsequently we wondered about how these types of myths and rumors come into being.    Myths about the brain typically arise in this fashion: An intriguing experimental result generates a plausible if speculative interpretation (a small part of the lobe seems sufficient) that is later overextended or distorted (we use only 10 percent of our brain). The caricature ultimately infiltrates pop culture and takes on a life of its own, quite independent from the facts that spawned it.

Another such myth is the idea that the left and right hemispheres of the brain are fundamentally different. Are you a creative and emotional person? Maybe an artist or a musician? Then you are probably right-brained. No? Perhaps you are a rational, analytical and logical thinker? Maybe a mathematician or an engineer? Then you are most likely left-brained. Who does not know that creativity and emotion are located in the right half of the brain, while rationality and logic are situated in the left half of the brain? Everyone has come across this popular notion of left or right brain dominance, which determines a person’s way of thinking and his/her personality. This notion, however, is a widely held misconception.

Scientists at the University of Utah have debunked the myth with an analysis of more than 1,000 brains. They found no evidence that people preferentially use their left or right brain. All of the study participants — and no doubt the scientists — were using their entire brain equally, throughout the course of the experiment. A paper describing this study appeared in August 2013 in the journal PLOS ONE.

Blink: The Power of Thinking Without Thinking (Book Review)

Gladwell’s talent is for weaving together scientific research findings from fields as diverse as sociology, psychology, criminology and marketing with an anecdotal style to create new ways of looking at things for the popular reader.

Blink, Gladwell’s follow-up bestseller to The Tipping Point, is a more purely psychological work, leaning on the research of Timothy Wilson, a professor at the University of Virgininia who has written about the ‘adaptive unconscious’, that part of our minds which can lead us to good decisions even though we don’t know how we make them; and Gary Klein, a cognitive psychologist who is an expert on how people arrive at decisions under pressure.

Blink is an attempt to bring to the public’s eye this emerging area of psychology, rapid cognition, that has received little popular attention.

The “10% brain” Myth

Let me state this very clearly:

There is no scientific evidence to suggest that we use only 10% of our brains.

It is quite remarkable that a handful of ideas from the field of neuroscience spread like wildfire through the popular media, thereby becoming part of our culture and worldview, while other ideas remain neglected, known only to a small group of experts. Since I was little, I always heard that humans use only 10% of their brains. To me, this idea agreed with the age-old notion that we as humans have great potential. Years later, I learned the 10% myth most likely arose from a misunderstanding (or misrepresentation) of neurological research in the late 19th century or early 20th century.

The popular notion that large parts of the brain remain unused, and could subsequently be “activated”, is not based on scientific theory. Several books, films, and short stories have been written closely related to this myth. They include the novel “The Dark Fields”, and its film adaptation “Limitless” (claiming 20% rather than the typical 10%), as well as the 2014 film “Lucy”, all of which operate under the notion that the rest of the brain could be accessed through use of a drug. Lucy, in particular, depicts a character who gains increasingly godlike abilities once she surpasses 10%.

Hacking The Brain With Electricity — Don’t Try This At Home

by Amy Standen (Re-post from NPR)

It’s the latest craze for people who want to improve their mental performance — zapping the brain with electricity to make it sharper and more focused. It’s called “brain hacking,” and some people are experimenting with it at home.

The idea’s not completely crazy. Small jolts of electricity targeted at specific areas of the brain are used to treat diseases like epilepsy and Parkinson’s disease.

an Interactive Map of Our Brain

How can we begin to understand the way the brain works? The same way we begin to understand a city: by making a map. In this visually stunning talk, Allan Jones shows how his team is mapping which genes are turned on in each tiny region, and how it all connects up. As CEO of the Allen Institute for Brain Science, Allan Jones leads an ambitious project to build an open, online, interactive atlas of the human brain.

The Allen Institute for Brain Science — based in Seattle, kickstarted by Microsoft co-founder Paul Allen — has a mission to fuel discoveries about the human brain by building tools the entire scientific community can use. As CEO, one of Allan Jones’ first projects was to lead the drive to create a comprehensive atlas of the brain of a mouse. Flash forward to April 2011, when the Allen Institute announced the first milestone in its online interactive atlas of the human brain, showing the activity of the more than 20,000 human genes it contains. It’s based on a composite of 15 brains, since every human brain is unique.

The mystery of teenage brain in 14 minutes

Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically “teenage” behavior is caused by the growing and developing brain.

Sarah-Jayne Blakemore studies the social brain — the network of brain regions involved in understanding other people — and how it develops in adolescents.

Handwriting Trains children’s Brain – find out how

Ask preschooler Zane Pike to write his name or the alphabet, then watch this 4-year-old’s stubborn side kick in. He spurns practice at school and tosses aside workbooks at home. But Angie Pike, Zane’s mom, persists, believing that handwriting is a building block to learning.

She’s right. Using advanced tools such as magnetic resonance imaging, researchers are finding that writing by hand is more than just a way to communicate. The practice helps with learning letters and shapes, can improve idea composition and expression, and may aid fine motor-skill development.

It’s not just children who benefit. Adults studying new symbols, such as Chinese characters, might enhance recognition by writing the characters by hand, researchers say. Some physicians say handwriting could be a good cognitive exercise for baby boomers working to keep their minds sharp as they age.

Reason that we have a brain?

Neuroscientist Daniel Wolpert starts from a surprising premise: the brain evolved, not to think or feel, but to control movement. In this entertaining, data-rich talk he gives us a glimpse into how the brain creates the grace and agility of human motion.
