(Editor's Note: interviewing Richard Nisbett, author of the excellent recent book Intelligence and How to Get It: Why Schools and Cultures Count, was in my To Do list. I then found that fellow blogger David DiSalvo was faster than I was and did a great job, so here we bring you David's interview and take).

While the debate over intelligence rages on many fronts, the battle over the importance of heredity rages loudest. It’s easy to see why. If the camp that argues intelligence is 75 to 85 percent genetically determined is correct, then we’re faced with some tough questions about the role of education. If intelligence is improved very little by schools, and if the IQ of the majority of the population will remain relatively unchanged no matter how well schools perform, then should school reform really be a priority?

More to the point, if our genes largely determine our IQ, which in turn underlies our performance throughout our lives, then what is the role of school? For some in this debate the answer to that question is simply, “to be the best you can be.” But that seems little comfort for those who aspire to “be” more than what their IQ category predicts they will.

Those on the other side of this debate question whether heredity plays as big a role as the strong hereditarians claim. And for the role it does play, they question whether hereditability implies immutability. Heredity of height, for example, is about 90 percent, and yet average height in several populations around the world has been steadily increasing due to non-genetic influences, like nutrition. If such a strong hereditary trait can be radically altered by environmental factors–and height is but one example of this–then why is intelligence different?

It is not, argues the camp that might best be described as intelligence optimists. For them, the pessimism that colors the strong hereditarian position isn’t only discouraging, it’s dangerous. Too much is hanging in the balance for pessimism about the potential of our children to prevail.

Richard Nisbett is a champion of the intelligence optimist camp, and with his latest book, Intelligence and How to Get It: Why Schools and Cultures Count , he has emerged as the most persuasive voice marshalling evidence to disprove the heredity-is-destiny argument. Intellectual advancement, Nisbett argues, is not the result of hardwired genetic codes, but the province of controllable factors like schools and social environments–and as such, improving these factors is crucially important.

This is a partial list of the literature we reviewed during the research phase of our new book, The SharpBrains Guide to Brain Fitness.  We know many friends of SharpBrains are researchers, healthcare professionals, graduate/ Ph.D. students, who want have direct access to the references (perhaps PubMed should promote itself as a never ending source of mental stimulation?), so here you have this list, organized by relevant chapter. Please note that the list below appears in the book - whose manuscript we had to close in January 2009.

Longevity Dividend

Ever heard of the Longevity Dividend? Perhaps Grey is the New Gold: The Kronos Longevity Research Institute has released a new report summarizing the state of aging research that includes an excellent introduction into the Longevity Dividend, a "theory that says we hope to intervene scientifically to slow the aging process, which will also delay the onset of age-related diseases. Delaying aging just seven years would slash rates of conditions like cancer, diabetes, Alzheimer’s disease and heart disease in half." With that context in mind, is the National Institute on Aging getting its fair budget share?

Education & Learning

10% Students may have working memory problems: Why does this matter?: A recent study screened over 3,000 school-aged students in schools in the UK and found that 1 in 10 was identified as having working memory difficulties. Working memory is our ability to store and manipulate information for a brief time, and difficulties in this brain function may lead into difficulties in reading and mathematics. Dr. Tracy Alloway reviews the study and elaborates.

Physical Fitness Improves Spatial Memory, Increases Size Of Brain Structure (Science Daily)

- "Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit."

- "Certain activities are believed to modify hippocampus size in humans. For example, a study of London taxi drivers found that the posterior portion of the hippocampus was larger in experienced taxi drivers than in other subjects. And a study of German medical students found that the same region of the hippocampus increased in size as they studied for their final exams."

- "Studies also have found that the hippocampus shrinks with age, a process that coincides with small but significant cognitive declines. The rate at which this occurs, however, differs among individuals."

Brain Plasticity: How learning changes your brain

"Whatever you struggle with in a sense as it stems from your neurology, the inherent plasticity of the brain gives you a basis for improvement. This is a way underutilized and under-appreciated resource that well all have." Dr. Michael Merzenich on the Brain Science Podcast #54, 2/13/09.

Recently there has been growing controversy about the effectiveness of computer-based cognitive training programs. As a co-founder of Posit Science, Inc. Dr. Michael Merzenich is a staunch defender of the methods his company uses to validate the programs that they have developed. But for the purposes of this essay, I want to share some of the key ideas we discussed during his recent interview on the Brain Science Podcast.

First of all, I asked him to discuss some of the highlights of his long career. Since he was one of the first neuroscientists to embrace the concepts of neuroplasticity I was curious about how this came about. While he did have some exposure to the animal evidence as a graduate student, it was actually his experience with the invention of the cochlear implant that convinced Dr. Merzenich of the real-world, practical implications of brain plasticity. The quality of the Continue Reading »

The growing field of cognitive training (one of the tools for brain fitness) can appear very confusing as the media keeps reporting contradictory claims. These claims are often based on press releases, without a deeper evaluation of the scientific evidence.

Let’s take a couple of recent examples, in successive days:

“It doesn’t work!” type of headline:
Reuters (Feb. 10, 2009) — Formal brain exercise won't help healthy seniors: research
“Healthy older people shouldn't bother spending money on computer games and websites promising to ward off mental decline, the author of a review of scientific evidence for the benefits of these "brain exercise" programs says”.

“It works!” type of headline:
ScienceDaily (Feb. 11, 2009) — Computer Exercises Improve Memory And Attention, Study Suggests
“According to the researchers, participants who used the Brain Fitness Program also scored as well as those ten years younger, on average, on memory and attention tests for which they did not train.”

So… does structured brain exercise / cognitive training work or not?

The problem may in fact reside in asking this very question in the first place, as Alvaro pointed out a while ago in his article “Alzheimer's Disease: too serious to play with headlines“.

We need a more nuanced set of questions.

Why? Because:
1. Cognition is made of several different abilities (working memory, attention, executive functions such as decision-making, etc)
2. Available training programs do not all train the same abilities
3. Users of training programs do not all have the same needs or goals
4. We need to differentiate between enhancing cognitive functions and delaying the onset of cognitive deficits such as Alzheimer’s.

Let’s illustrate these points, by Continue Reading »

Last week, in this article's first part, we discussed the importance of actually teaching children how to get themselves into a physical state of being relaxed, explored several suggestions I hope you found useful.

Let's continue.

Teachers can help student overcome stress by teaching them to identify the impediments they might encounter in doing a certain task.

The teacher can ask:

What's going to get in the way of you doing this work?
He or she may have to jump-start the students’ thinking by suggesting such things as:
- competing events (family activities, friends call, IM-ing, new video game, etc.)
- lack of adequate place to study
- inadequate prior preparation or skills
- a negative attitude (this is not necessary, I can't do math, I’ll never need to know this, etc).
- health factors (I’m sick; I’m tired)

Conversely, teachers have to teach students to identify the enhancers; What's going to make it more likely that you will do this, and do this well?
(examples)
- I have confidence in my ability
- I feel competent in this skill
- I am committed to learning this because: I have the necessary resources to complete this task, such as materials, sources of information, people supports; parents, tutor, other kids

Teachers can turn distress into de-stress by using the Language of Success

The key is to de-emphasize PRAISE and emphasize SELF-APPRAISAL.

Teachers can encourage self-evaluation by Continue Reading »
