Over the last year we have interviewed a number of leading brain health and fitness scientists and practitioners worldwide to learn about their research and thoughts, and have news to report.

What can we say today that we couldn't have said only 10 years ago? That what neuroscience pioneer Santiago Ramon ySantiago Ramon y Cajal Cajal claimed in the XX century, "Every man can, if he so desires, become the sculptor his own brain", may well become reality in the XXI. And influence Education, Health, Training, and Gaming in the process.

We have only scratched the surface of what science-based structured cognitive (i.e., mental) exercise can do for brain health and productivity. We are now witnessing the birth of a new industry that crosses traditional sector boundaries and that may help us understand, assess and train our brains, harnessing the growing research about neurogenesis (the creation of new neurons), neuroplasticity (the ability of the brain to rewire itself through experience), cognitive training and emotional regulation.

Let's now debunk 10 myths, still too prevalent, that may prevent us from seeing the full potential of this emerging field:

Myth 1: It’s all in our genes.

Reality: A big component of our lifelong brain health and development depends on what we do with our brains. Our own actions, not only our genes, influence our lives to a large extent. Genes predispose us, not determine our fates.

• “Individuals who lead mentally stimulating lives, through education, occupation and leisure activities, have reduced risk of developing Alzheimer’s. Studies suggest that they have 35-40% less risk of manifesting the disease” - Dr. Yaakov Stern, Division Leader of the Cognitive Neuroscience Division of the Sergievsky Center at Columbia University.

Myth 2: The field of Cognitive/ Brain Fitness is too new to be credible.

Reality: The field rests on solid foundations dating back more decades --- what is new is the number and range of tools that are now starting to be available for healthy individuals.

• “Rigorous and targeted cognitive training has been used in clinical practice for many years. Exercising our brains systematically is as important as exercising our bodies.” - Dr. Elkhonon Goldberg, neuropsychologist, Frontal Lobes fMRIclinical professor of neurology at New York University School of Medicine, and disciple of Alexander Luria.

• "Today, thanks to fMRI and other neuroimaging techniques, we are starting to understand the impact our actions can have on specific parts of the brain." - Dr. Judith Beck, Director of the Beck Institute for Cognitive Therapy and Research.

Myth 3: Medication is and will remain the only evidence-based intervention for a number of brain-related problems.

Reality: Cognitive training programs are starting to show value as complements to drug-based interventions.

• “Cognitive training rests on solid premises, and some programs already have very promising research results"- Professor David Rabiner, Senior Research Scientist and Director of Psychology and Neuroscience Undergraduate Studies at Duke University.

Myth 4: We need to buy very expensive stuff to improve our brains.

Reality: Every time we learn a new skill, concept or fact, we change the physical composition of our brains. Lifelong learning means lifelong neuroplasticity.neurons

• “Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections–called synapses– and neuronal networks, through experience...we are cultivating our own neuronal networks.” - Dr. James Zull, Professor of Biology and Biochemistry at Case Western University,

Myth 5: Schools should just focus on basic skills like Reading and Math.

Reality: “Mental muscles,” such as working memory, are fundamental to academic performance and are currently overlooked by the school system.

• “I don't see that schools are applying the best knowledge of how minds work. Schools should be the best place for applied neuroscience, taking the latest advances in cognitive research and applying it to the job of educating minds.” - Dr. Arthur Lavin, Associate Clinical Professor of Pediatrics at Case Western School of Medicine.

Myth 6: Crossword puzzles, or our daily job activities, are the best way to keep one’s mind sharp.

Reality: Computer-based programs can be more effective at training specific cognitive skills.

• “What research has shown is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.” - Dr. Daniel Gopher, Professor of Human Factors Engineering at Technion Institute of Science.

Myth 7: Videogames are always a waste of time.

Reality: Scientifically-designed, computer-based programs can be a good vehicle for training specific skills. For example, it has been shown that short term memory can be expanded by such programs.

• “We have shown that working memory can be improved by training.” – Dr. Torkel Klingberg, Director of the Developmental Cognitive Neuroscience Lab at Karolinska Institute.

Myth 8: This means kids will spend more time playing videogames.

Reality: In Japan – the world’s earliest adopter of brain-related videogames- overall home videogame sales have declined, with children playing less over time. Interestingly, adults in Japan have started to play brain-related video games more, and we are starting to see the same trend with adults in the US and Europe.

• “The sales of software on home game machines have declined (in Japan) from its peak of 533 billion yen in 1997 to 53% of that amount, 315 billion yen in 2005” --- Go Hirano, Japanese executive.

Myth 9: Brain exercise is only for seniors. And, only about memory.

Reality: People of all ages can benefit from a variety of regular brain exercises. For active professionals, Working memorymanaging stress and emotions is often a good first step.

• “The elite performers are distinguished by the structuring of their learning process. It is important to understand the role of emotions: they are not “bad”. They are very useful signals. It is important to become aware of them to avoid being engulfed by them, and learn how to manage them.” - Dr. Steenbarger, Associate Professor of Behavioral Sciences at SUNY Upstate Medical University, and author of the book Enhancing Trader Performance.

Myth 10: This all sounds too soft to be of real value to managers and professionals.

Reality: There is nothing soft about the hard science-based training of specific cognitive and emotional skills.

• “I can easily see the relevance in highly competitive fields, such as professional sports and military training.” - Dr. Bradley Gibson, Director of the Perception and Attention Lab at University of Notre Dame.

The Harvard Business Review just published (thanks Catherine!) this article on cognitive fitness, by Roderick Gilkey and Clint Kilts. We are happy to see the growing interest on how to maintain healthy and productive brains, from a broadening number of quarters. Without having yet fully read the article...it seems to provide a reasonable introduction to brain science, yet could have more beef regarding assessment, training and recommendations. In such an emerging field, though, going one step at a time makes sense. What really matters is thet fact itself that it was published.

The HBR Description of the article:   

Recent neuroscientific research shows that the health of your brain isn't, as experts once thought, just the product of childhood experiences and genetics; it reflects your adult choices and experiences as well. Professors Gilkey and Kilts of Emory University's medical and business schools explain how you can strengthen your brain's anatomy, neural networks, and cognitive abilities, and prevent functions such as memory from deteriorating as you age. The brain's alertness is the result of what the authors call cognitive fitness--a state of optimized ability to reason, remember, learn, plan, and adapt. Certain attitudes, lifestyle choices, and exercises enhance cognitive fitness. Mental workouts are the key. Brain-imaging studies indicate that acquiring expertise in areas as diverse as playing a cello, juggling, speaking a foreign language, and driving a taxicab expands your neural systems and makes them more communicative. In other words, you can alter the physical makeup of your brain by learning new skills. The more cognitively fit you are, the better equipped you are to make decisions, solve problems, and deal with stress and change. Cognitive fitness will help you be more open to new ideas and alternative perspectives. It will give you the capacity to change your behavior and realize your goals. You can delay senescence for years and even enjoy a second career. Drawing from the rapidly expanding body of neuroscientific research as well as from well-established research in psychology and other mental health fields, the authors have identified four steps you can take to become cognitively fit: understand how experience makes the brain grow, work hard at play, search for patterns, and seek novelty and innovation. Together these steps capture some of the key opportunities for maintaining an engaged, creative brain.

The authors do mention part of the research done by Dr. Elkhonon Goldberg (our co-founder and Chief Scientific Advisor) on pattern-recognition. You will enjoy reading his thoughts directly:
As well as our interviews with a number of other leading scientists in this Neuroscience Interview Series.

- “Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections–called synapses– and neuronal networks, through experience...When we do so, we are cultivating our own neuronal networks. We become our own gardeners”- Dr. James Zull, Professor of Biology and Biochemistry at Case Western University. Full Interview Notes.

- “Exercising our brains systematically is as important as exercising our bodies. In my experience, “Use it or lose it” should really be “Use it and get more of it”.- Dr. Elkhonon Goldberg, neuropsychologist, clinical professor of neurology at New York University School of Medicine, and disciple of the great neuropsychologist Alexander Luria. Full Interview Notes.

- "Today, thanks to fMRI and other neuroimaging techniques, we are starting to understand the impact our actions can have on specific parts of the brain."- Dr. Judith S. Beck, Director of the Beck Institute for Cognitive Therapy and Research, and author of The Beck Diet Solution: Train Your Brain to Think Like a Thin Person. Full Interview Notes

- “What research has shown is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.” - Dr. Daniel Gopher, Director of the Research Center for Work Safety and Human Engineering at Technion Institute of Science. Full Interview Notes.

- “Individuals who lead mentally stimulating lives, through education, occupation and leisure activities, have reduced risk of developing Alzheimer’s symptoms. Studies suggest that they have 35-40% less risk of manifesting the disease”- Dr. Yaakov Stern, Division Leader of the Cognitive Neuroscience Division of the Sergievsky Center at the College of Physicians and Surgeons of Columbia University, New York. Full Interview Notes.

- "It is hardly deniable that brains enchant Japanese people. We love brain training. Dentsu, the biggest advertising agency, announced the No.1 Consumer-chosen 2006 Product was game software and books for brain training."- Go Hirano, Japanese executive, founder of NeuWell. Full Interview Notes.

- “Elite performers are distinguished by the structuring of their learning process… It is important to understand the role of emotions: they are not “bad”. They are very useful signals. It is important to become aware of them to avoid being engulfed by them, and learn how to manage them.” - Dr. Brett Steenbarger, Associate Professor of Psychiatry and Behavioral Sciences, SUNY Medical University, and author of Enhancing Trader Performance. Full Interview Notes.

- “We have shown that working memory can be improved by training...I think that we are seeing the beginning of a new era of computerized training for a wide range of applications” – Dr. Torkel Klingberg, Director of the Developmental Cognitive Neuroscience Lab at Karolinska Institute. Full Interview Notes.

- “Training is very important: attentional control is one of the last cognitive abilities to develop in normal brain development...I can easily see the relevance in 2 fields. One, professional sports. Two, military training.” Professor Bradley Gibson is the Director of the Perception and Attention Lab at University of Notre Dame. Full Interview Notes.

May I quote this Los Angeles Times article and say that

- "I see this as a new frontier of fitness overall," says Alvaro Fernandez, founder and chief executive of the website SharpBrains .com, which tracks the business and science of brain-training. Americans already understand the value of physical fitness as a means of preserving the body's proper function and preventing age-related diseases, says Fernandez.

- He predicts that cognitive fitness will become a goal to which Americans equally aspire as we learn more about aging and the brain.

Pretty easy prediction, given what we are seeing and doing every day.

Now, the real merit goes to neuroscientists like Dr. Goldberg and many other pioneers who have been saying so for the last 10 years, and doing the hard work. And, of course, for each of us who try our best every day to keep our brains and minds healthy and productive, and do more than wait for a magic pill to arrive.

An anonymous reader of Andrew Sullivan's blog writes a superb comment, reproduced here:

"One thing Watson and others forget is that the brain is highly malleable based on environment. Although he is the father of DNA he knows very little about neuroplasticity and neurogenesis. Previously it was thought that the human brain was 'hardwired' after a certain age. This is not true. Not only is not true, but the human mind is capable of adaptation but actual neuron growth even late in life. Ten years ago this was thought impossible.

Neurogenesis and neuroplasticity proves that a nurturing social and family setting shifts IQ, perspective, and emotional IQ. The so-called bell curve isn't genetic. Oppressed Tibetans and Chinese ethnic minorities -whose test scores soar in the United States and Canada- are 20-30 points lower in their homeland. That 20-30 points deficit is in the same range of a lot of groups that are attacked or threatened (Muslims in France, Christians in Nigeria, Blacks in America). Conversely when oppressed groups are removed from their environment their IQ, emotional health returns to a normal rate, thus proving that is NOT genetic.

It is plastic, shifting and based upon the environment.

That is why people under prolonged stress experience memory loss, emotional outbursts and many other symptoms of a mind that is under duress. When the stress ends, normal memory levels return. A Black male living in the inner city in a single parent household facing an assortment of threats is obviously going to test differently than a white child growing up in the suburbs in a nurturing environment.

What is concerning about this growing myth in the end-all-be-all power of genes is that it leaves people helpless. There is apparently a fat gene, an Alzheimers gene, and what next? A stupid gene? This is genetic determinism and it's not only a false scientific creation but down-right scary. It leaves people waiting around for 'the magic pill,' helpless and perpetual victims. It makes doctors and scientists as God and turns the average human into a lab rat."

Beautifully said.

You will enjoy this related post on Richard Dawkins and Alfred Nobel: beyond nature and nurture, where we quote Richard Dawkins:

"We have the power to defy the selfish genes of our birth and, if necessary, the selfish memes of our indoctrination. We can even discuss ways of deliberately cultivating and nurturing pure, disinterested altruism-something that has no place in nature, something that has never existed before in the whole history of the world. We are built as gene machine and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators."

San Francisco Golden Gate BridgeContext: Last February we had the chance to attend a great conference on how brain research is influencing education. Highly recommended. Caroline wrote our impressions, summarized as "It was a fascinating mix of neuroscientists and educators talking with and listening to each other. Some topics were meant to be applied today, but many were food for thought - insight on where science and education are headed and how they influence each other". See some of our take-aways below.

Announcement: the 2008 edition of this conference, titled Using Brain Research to Enhance Learning, Attention & Memory For Educators, Parents and Clinicians, will take place in San Francisco,  on February 7-9th, 2008. The organizers have kindly invited me to deliver a lecture on Interventions to Sharpen Minds, as part of the Brain Plasticity & Attention track. I will provide an overview of the science behind computer-based cognitive training interventions and discuss a number of research-based programs that are being used today. Let me know if you are planning to attend!

Registration fees: the general registration fees are $495 per person, if you register before January 25th, 2008.

Special Discount for SharpBrains readers: you can register for $450 before that date,  making sure to write
SharpBrains1 in the comments section of How did you hear about the conference? in this Registration Page

To learn more about the conference:

Program overview: click here

Co-sponsors: click here

 Here you have some of our take-aways from last conference:

- Humans are a mixture of cognition and emotion, and both elements are essential to function and learn properly

- Educators and public policy makers need to learn more about the brain, how it grows, and how to cultivate it

- Students of all ages need to be both challenged and nurtured in order to succeed

- People learn differently - try to teach and learn through as many different modalities as possible (engage language, motor skills, artistic creation, social interaction, sensory input, etc.)

- While short-term stress can heighten your cognitive abilities, long term stress kills you — you need to find balance and release

- Test anxiety and subsequent poor test results can be improved with behavioral training with feedback based on heart rate variability

- Dr. Robert Sapolsky is a very very enlightening and fun speaker

- Allow time for rest and consolidation of learned material

- Emotional memories are easier to remember

- Conferences like these perform a real service in fostering dialogues between scientists and educators

Charles Darwin 1880Charles Darwin (1809-1882)'s autobiography (full text free online) includes some very insightful refections on the evolution of his own mind during his middle-age, showcasing the power of the brain to rewire itself through experience (neuroplasticity) during our whole lifetimes-not just when we are youngest.

He wrote these paragraphs at the age of 72 (I have bolded some key sentences for emphasis, the whole text makes great reading):

"I have said that in one respect my mind has changed during the
last twenty or thirty years
. Up to the age of thirty, or beyond
it, poetry of many kinds, such as the works of Milton, Gray,
Byron, Wordsworth, Coleridge, and Shelley, gave me great
pleasure, and even as a schoolboy I took intense delight in
Shakespeare, especially in the historical plays. I have also
said that formerly pictures gave me considerable, and music very
great delight. But now for many years I cannot endure to read a
line of poetry: I have tried lately to read Shakespeare, and
found it so intolerably dull that it nauseated me. I have also
almost lost my taste for pictures or music. Music generally sets
me thinking too energetically on what I have been at work on,
instead of giving me pleasure. I retain some taste for fine
scenery, but it does not cause me the exquisite delight which it
formerly did.
On the other hand, novels which are works of the
imagination, though not of a very high order, have been for years
a wonderful relief and pleasure to me, and I often bless all
novelists. A surprising number have been read aloud to me, and I
like all if moderately good, and if they do not end unhappily--
against which a law ought to be passed. A novel, according to my
taste, does not come into the first class unless it contains some
person whom one can thoroughly love, and if a pretty woman all
the better.
This curious and lamentable loss of the higher aesthetic tastes
is all the odder, as books on history, biographies, and travels
(independently of any scientific facts which they may contain),
and essays on all sorts of subjects interest me as much as ever
they did. My mind seems to have become a kind of machine for
grinding general laws out of large collections of facts, but why
this should have caused the atrophy of that part of the brain
alone, on which the higher tastes depend, I cannot conceive
. A
man with a mind more highly organised or better constituted than
mine, would not, I suppose, have thus suffered; and if I had to
live my life again, I would have made a rule to read some poetry
and listen to some music at least once every week; for perhaps
the parts of my brain now atrophied would thus have been kept
active through use.
The loss of these tastes is a loss of
happiness, and may possibly be injurious to the intellect, and
more probably to the moral character, by enfeebling the emotional
part of our nature."

We have already discussed how "cells that fire together wire together". The neurons and synapses that we use often grow over time; the ones we don't use get weakened.  As it seems, Darwin implicitly trained himself to develop a highly methodical and analytical mindset, while, as he posits, not devoting enough time to other interests. Check out this paragraph (which precedes the previous two in the original text):

"Having said thus much about my manner of writing, I will add that
with my large books I spend a good deal of time over the general
arrangement of the matter. I first make the rudest outline in
two or three pages, and then a larger one in several pages, a few
words or one word standing for a whole discussion or series of
facts. Each one of these headings is again enlarged and often
transferred before I begin to write in extenso. As in several of
my books facts observed by others have been very extensively
used, and as I have always had several quite distinct subjects in
hand at the same time, I may mention that I keep from thirty to
forty large portfolios, in cabinets with labelled shelves, into
which I can at once put a detached reference or memorandum. I
have bought many books, and at their ends I make an index of all
the facts that concern my work; or, if the book is not my own,
write out a separate abstract, and of such abstracts I have a
large drawer full. Before beginning on any subject I look to all
the short indexes and make a general and classified index, and by
taking the one or more proper portfolios I have all the
information collected during my life ready for use."

Little by little, he created his own, personalized Yahoo directory and prediction algorithm...and his "mind seems to have become a kind of machine for grinding general laws out of large collections of facts". 

Some final remarks by this amazing scientist and man:

"Therefore my success as a man of science, whatever this may have
amounted to, has been determined, as far as I can judge, by
complex and diversified mental qualities and conditions. Of
these, the most important have been--the love of science--
unbounded patience in long reflecting over any subject--industry
in observing and collecting facts--and a fair share of invention
as well as of common sense. With such moderate abilities as I
possess, it is truly surprising that I should have influenced to
a considerable extent the belief of scientific men on some
important points."

Fitness TrainerA reader (thanks Mike!) sends us this fun article, titled A matter of training, on how to train our memory. Some quotes:

“It’s a skill, not a talent. It’s something anyone could have picked up ... I’m not born with this. It’s about training and technique,” he says, explaining his unusual ability. Anant holds the Limca Record – the Indian equivalent of the Guinness Record – for memorising 75 telephone numbers, along with the names of their owners, in less than an hour. He is recognised as “the man with the most phenomenal memory in India.”  

“Unfortunately, most people think that memorising is very difficult. The moment they see someone demonstrate something like this, they think it’s out of this world.”

If you want to remember something, you have to link it to something you already know. Association is the natural principal. For example, if you need directions to a place, a landmark is often used as a point of reference. And if you derive pleasure from something you do, there’s a good chance you’ll remember it. Since the brain already works in this manner, why don’t we take control of it?” 

“To me, an intelligent person is someone who is able to put together more of his skills to solve a problem. Intelligence is about using strategies.” 

The key concept here is that memory, as well as other cognitive skills, can be trained through directed exercise. Which means we can improve our peak capacity, and also delay potential decline. Now, there are not magic pills, but "brain fitness" exercises, in the same way we go to the gym to train some muscles. You can read about a very powerful memory technique, called loci method or memory palace, that requires training and has been used since classic Greece. Maybe the Oldest Brain Fitness Program?

In the related post Neuroplasticity and Lifelong Learning we talked about other types of "brain exercises":

Just today we found out that Sharp sums in the head aim to blunt impact of TV, on a topic we have been discussing for a few weeks with several of our scientific advisors. We quote:

"Gilles de Robien, the Education Minister (in France), has ordered children to carry out between 15 and 20 minutes of calcul mental (mental arithmetics) every day from the age of 5. Mr de Robien moved after a report from the French Science Academy said that children who practiced sums in their heads had better memories and quicker brains.

Questions for the final year of French primary school

Crosslinguistic Influence in Language and Cognition

  • By Scott Jarvis, Aneta Pavlenko
This book is a cogent, clearly-written synthesis of new and classic work on crosslinguistic influences on language and thought. Intended as a text for upper-level undergraduates and graduate students, it will also serve as a resource for instructors and scholars in applied linguistics, linguistics, and psycholinguistics courses. This topic is a perennial favorite in courses on bilingualism, psycholinguistics, and even cognitive psychology. t has come into even sharper focus over the past decade with the rapid increase in the availability of crosslinguistic data from languages other than English.

Information overloadWe often talk in this blog about how to expand fundamental abilities or cognitive functions, like attention, or memory, or emotional self-regulation. Think of them as muscles one can train. Now, it is also important to think of ways one can use our existing muscles more efficiently.

Let's talk about how to manage better the overwhelming amount of information available these days.

Hundreds of thousands of new books, analyst reports, scientific papers published every year. Millions of websites at our googletips. The flow of data, information and knowledge is growing exponentially, stretching the capacity of our not-so-evolved brains. We can complain all day that we cannot process ALL this flow. Now, let me ask, should we even try?

Probably not. Why engage in a losing proposition. Instead, let me offer a few strategies that can help manage this flow of information better. From "process" to "manage".

1. Prioritize: strategic consulting firms such as McKinsey and BCG train their staff in the so-called 80/20 rule: 80% of effects are caused by the top 20% of causes. In a company, 80% sales may come from 20% of the accounts. Implication: focus on that top 20%; don't spend too much time on the 80% that only account for 20%.

2. Leverage a scientific mindset. Scientists shift through tons of data in efficient, goal-oriented ways. How do they do it? By first stating a hypothesis and then looking for data. For example, an untrained person could spend weeks "boiling the ocean", trying to read as much as possible, in a very fragmentary way, about how physical exercise affects our brain. A trained scientist would first define clear hypotheses and preliminary assumptions, such as "Physical exercise can enhance the brain's ability to generate new neurons" or "Those new neurons appear in the hippocampus", and then look specifically for data that corroborates or refutes those sentences, enabling him or her to refine the hypotheses further, based on accumulated knowledge, in a virtuous learning cycle.     

3. Link the new information to previous one. One cannot process, or remember, millions of fragmented, random facts. Preparing concept maps, either in paper or using software tools, is a great method to build expert knowledge and pattern-recognition over time, the opposite of being lost in a sea of random tidbits. Here is an example: a concept map of concept maps:

 

 

 

 

 

     

4. Set Clear Goals to achieve this week/ month/ quarter. Maybe 3-5. Write them down, and review periodically. Why is this useful? Because by stating those clear goals you are building you own lens through which to filter information, and focus on the information you really care about. You set up your own agenda, and not be at the mercy of someone else's brain. You don't need to know, you really don't need to know (unless you work in Entertainment Weekly), what is going on with celebrity XYZ this week.     

5. Review those goals at the end of the week/ month/ quarter. Did you achieve them? What could you have done differently?. The goal here is to ensure a learning loop. You can "evolve your brain" in your lifetime by making sure you learn a bit every day, every week, and accumulate knowledge and abilities over time.

 

6. Stress and anxiety are enemies of good information processing. They can narrow your focus of attention too much and make you miss the big picture. Why is this so? Well, imagine you are a gazelle about to be attacked by a tiger. You only care about running as fast as possible to escape. It is not the time for complex thinking, for learning new skills. In fact, most of the blood flow that usually goes to the brain gets diverted and gets sent to your main body muscles, to run faster. The same happens with humans, when we see a real or imaginary "tigers": one can not think clearly.

 

7. Another enemy: excessive TV watching. Watching TV five hours a day has an effect on your brain: it trains one's brain to become a visual, usually unreflective, passive recipient of information. You may have heard the expression "Cells that fire together wire together". Our brains are composed of billions of neurons, each of which can have thousand of connections to other neurons. Any thing we do in life is going to activate a specific networks of neurons. Visualize a million neurons firing at the same time when you watch a TV program. Now, the more TV you watch, the more those neurons will fire together, and therefore the more they will wire together (meaning that the connections between them become, physically, stronger), which then creates automatic-like reactions. A heavy TV-watcher is making himself or herself more passive, unreflective, person. Exactly the opposite of what one needs to apply the other tips described here.

 

I hope this is helpful. Feel free to share your own tips.

Cognition and Extended Rational Choice

  • By Howard Margolis

"Twenty-five years ago I strongly recommended Margoliss 'Selfishness, Altruism, and Rationality.' Now, five books later, it is exciting to see how much farther hes taken that theory, supported it with an extensive review of laboratory experiments, and applied it to groups, large and small, resolving numerous puzzles along the way."

Thomas C. Schelling , 2005 Nobel Prize Laureate in Economics

One of the most exciting recent innovations in the social sciences has been the emergence of 'behaviour economics', which extends the notion of rational choice to allow for both motivation beyond self-interest and intuitions that cannot be reduced to the logic of a situation. This new book by Howard Margolis demonstrates how an account of widely-discussed topics, from tipping points in social choice to cognitive illusions and experimental anomalies, can be brought within a coherent framework.

Starting from Darwin's own comments on the origins of moral concerns and from a review of notorious cognitive illusions, Margolis shows how rational choice theory can be extended to incorporate social as well as self-interested motivation, but allowing for the cognitive complications that can be expected in domains well-outside familiar experience. This yields a coherent account of many otherwise mystifying results from cooperation experiments.

This book will be of great interest not only to students and researchers in behavioral and experimental economics but across the social sciences.

Memory

  • Edited by Jackie Andrade

The term memory encompasses our recollections of past experiences, our ability to keep track of what is happening from moment to moment, our stored knowledge, including knowledge of words and their meanings, our habits, our recognition of objects and faces, and our ability to remember to do things in the future. As such, an understanding of memory is central to an understanding of human behaviour. Memory supports our ability to speak and decode language, to find our way around, to make rational decisions, and to function successfully in society. Moreover, memory of past life-events contributes to our unique individual personalities.

Memory research has a long and important history within psychology and it continues to have fascinating everyday applications. Memory research has also helped us to understand the effects of brain damage, and has also been used to predict scholastic achievement and language development. However, memory has become such a broad field of study and research that it is extremely hard to keep up to date with new developments. The sheer scale of the growth in memory research outputand the breadth of the fieldmakes this new collection from Psychology Press especially timely and welcome. It will enable ready access to the most influential and important works across the full gamut of the discipline, encouraging a broader appreciation of the field and mutual influences within it.

Edited by a leading memory researcher, the four volumes in this collectionon the structure of memory, memory processes (including theories of forgetting), working memory, and the constraints on memorybring together carefully selected key historical papers along with cutting-edge research. The organization of the collection, broadly by research domain, together with the editors newly written Introduction, will enable users to make sense of the wide range of approaches, theories, and concepts that have informed memory research to date. It is an essential reference work destined to be valued as a vital research resource by all scholars and students of the subject.

emWave for Stress ManagementVery good article in the LA Times today. Like a StairMaster for the brain: Can mental workouts improve the mind's agility? Baby boomer concerns stimulate an industry expansion.

The reporter, Melissa Healy, reviews the healthy aging segment in the Brain Fitness field. A few selected quotes:

- "There is plausibility, both biological and behavioral, to the claim that these may work," says Molly Wagster, chief of the National Institute on Aging's neuropsychology branch. "But it is still a situation of 'buyer beware.' "

- "I see this as a new frontier of fitness overall," says Alvaro Fernandez, founder and chief executive of the website SharpBrains .com, which tracks the business and science of brain-training. Americans already understand the value of physical fitness as a means of preserving the body's proper function and preventing age-related diseases, says Fernandez. He predicts that cognitive fitness will become a goal to which Americans equally aspire as we learn more about aging and the brain.
- (Dr. Elkhonon) Goldberg, who provides scientific advice on the website http://www.sharpbrains.com/, says that as neuroscientists use imaging technologies to "see" the cellular changes that come with learning, he grows more confident that well-designed training programs can have discernible everyday effects in preserving or repairing the intellectual function of older adults. "This is shared hardware" that's being changed in the brain, "and to the extent you somehow enhance it, that will have wide-ranging effects," Goldberg says. "It provides a much more compelling raison d'être for this whole business."

The article adds that "Americans this year are expected to invest $225 million in these programs --- up from just $70 million in 2003 --- in an effort to tune up the brain, strengthen the memory and forestall or reverse the cognitive slippage that often comes with age, psychiatric disease, stroke or medical treatments."

Our breakdown for those 2007 US predictions are as follows: $80m for the Consumer segment, $60m in K12 Education, $50m in Clinical applications, and $35m in the Corporate segment. The Consumer segment, with a healthy aging value proposition, is the most recent one but the most rapidly growing.

Read the full article: Like a StairMaster for the brain.

PS: the article also says "In the last three years, these brainpower-boosting programs have proliferated, with names like MindFit, Happy Neuron, Brain Fitness and Lumosity.".. if there are reporters reading this, please avoid future confusion by naming Posit Science's program "Posit Science Brain Fitness Program 2.0". Brain Fitness refers to the full category.
