Today in the NY Times: Interactions or Causes?

One can take the New York Times today to illustrate a basic dichotomy we frequently discuss on this site. To understand ourselves and the world, is it better to examine complex interactions and the mixing of human action and natural cause, or to draw on simpler explanations and the old cause-effect scientific model?

Given that this site is neuro-anthropology (which the Times has nicely illustrated), we obviously favor interdisciplinary over one-field approaches. Given today’s world, that matters.

Handle with Care by Cordelia Dean takes on technology, science and ethics. She specifically examines planet-level environmental engineering or “geoengineering”, but also mentions robotics and nanotechnology. We could add gene therapy and increasingly sophisticated pharmaceuticals to that list. Her basic point?

This technology might be useful, even life-saving. But it would inevitably produce environmental effects impossible to predict and impossible to undo. So a growing number of experts say it is time for broad discussion of how and by whom it should be used, or if it should be tried at all.

As Dean notes, it is an extremely difficult proposal, contravening the way many scientists approach their work, highlighting necessity of global systems to manage our increasing technical power, and raising the specter of “knowledge-enabled mass destruction.”

Just one example of this appears in today’s Times with Surpassing Nature, Scientists Bend Light Backwards which points both to the potential impact on microscopes and on invisibility cloaks.

In Handle with Care, Dean highlights that science for science’s sake is not the answer. Rather, Prof. Sheila Jasanoff argues that the “first step was for scientists and engineers to realize that in complex issues, ‘uncertainty, ignorance and indeterminacy are always present.’ In what she described as ‘a call for humility’ [in her Nature essay], she urged researchers to cultivate and teach ‘modes of knowing that are often pushed aside in expanding scientific understanding and technological capacity’ including history, moral philosophy, political theory and social studies of science — what people value and why they value it.”

David Brooks in Harmony and the Dream brings us directly into that debate of what people value. He argues that “The world can be divided in many ways — rich and poor, democratic and authoritarian — but one of the most striking is the divide between the societies with an individualist mentality and the ones with a collectivist mentality.”

Mental Health Tips

10 steps to better brain health:

 

 

1. A healthy diet. Glucose is the brain’s major source of energy, but a balanced diet is essential to body and brain function. Food with a low glycemic index (GI) like oats and bran as well as dark green leafy vegetables that are rich in magnesium are both believed to help brain function. Choline rich foods such as eggs and red meat are also thought to assist healthy communication between brain cells. Also, avoid substances that stress the brain and limit drugs like caffeine, nicotine and alcohol.

 

2. Stimulate your brain. No, put the super-charged magnetic coil down! I’m not talking about Transcranial Magnetic Stimulation. I’m talking about involving yourself in new activities, playing an instrument, learning to speak a foreign language, solving brain teasers. Exercise the brain as you would the body. The Brain operates on a use-it or lose-it policy. So use it! Play sudoku, solve a crossword puzzle and test your skills at scrabble!

 

3. Keep a diary. A great way to deal with stress, emotional worries and to relax at the end of a hectic day or a busy week is to sit down and write. It’s a fantastic way to see what you have achieved, frame new goals and keep your emotions in balance. Also, writing notes for yourself helps convert information stored in your short-term memory to long-term memory. So get that creative energy flowing and put pen to pad!

 

4. Sleep well! Getting a good night sleep is essential for concentration. It has been shown that regular sleep-wake cycles are important in daily cognitive performance. Dreams may be important in the consolidation of memory. As we all know, it feels great to rise and shine after we have slept like a baby!

           

5. Regular exercise! It is important for your entire body. Exercise is believed to be important in maintaining neural plasticity in old age and aerobic fitness may in fact reduce the loss of brain tissue common in ageing. Exercise also releases natural hormones that lead to those ‘feel good’ sensations. Feeling good about your body is vital to brain health.

 

6. Regulate your couch-time. Too much TV weakens brain power. But a little TV is great mental stimulation. Balance is the key!

 

7. Socialise! Familiar smiles, friendly conversations and meaningful interactions are all part of a healthy lifestyle. The brain is the organ of society and socialisation is an integral part of brain health. Join a book-club, learn to dance, smile at a colleague!

 

8. Organisation. We all know the anxiety that misplacing the house-keys or forgetting an appointment creates. Avoid the stress and make a special place for items such as reading glasses, wallets/purses or the TV remote.

 

9. Relax. Spend time on a hobby, take your dog for a walk or just sit back in a comfortable armchair with a great book. Technique to relax are not only useful to reduce stress and enhance brain performance, relaxation methods have also been shown to play a positive role in emotional health. For example, mindfulness meditation has been shown to decrease the recurrence of depression. Find a stress-reducing practice that suits your lifestyle and personal taste and then devote a balanced amount of time each week to it.

 

10. Positive thinking. Always look on the bright side of life (someone should turn that into a song)!

 

 

 

Transcultural Psychiatrists would certainly have a few dilemmas with the above list. The serious Neuroanthropologist probably does too! But what the heck, I put them here just for fun! Mind you, the list might lead to some interesting questions about what could be considered the definitive TOP 10 FOR BRAIN HEALTH applicable across cultures!

Top 100 at Online University Reviews

Online University Reviews, a site that tries to sort out which online universities are right for a candidate, has posted a list of its ‘Top 100 Mental Health and Psychology Blogs.’ If it’s a device to get people to visit their site, it worked for me.

There’s lots of old friends and frequent destinations in the list, as well as a few I had never heard of, but Neuroanthropology got picked. We’re glad to be included with some fine company and willing to put up a link (for whatever it’s worth to Open University Reviews).

Thanks to Kelly for passing along the notice.

Camping on the Brain

A week of camping in Michigan, and I did not think of the brain once. I was too physically active, too impacted by my senses, too involved with my family.

We all slept in one tent. We shared our meals, went to the beach together, and followed each other on hiking trails. Conversation, laughter, flare ups, it was all non-stop between us. No one off at work or at school. All the time, us.

The noises of the night surrounded us through the fabric walls of the tent, the wind amid the leaves, the lap of waves, a nightly fight between two raccoons, the birds in the morning. Smoke from our campfire filled our nostrils and stung our eyes, the warm and slightly acrid smell of burnt wood clinging to our clothes and our hair. The sun poured down on us, turning my boys nut brown and myself a reddish brown. No walls to shut nature away; my first night back I woke up feeling odd, realizing that it was too quiet, too enclosed, too soft.

I walked from the moment I woke to the moment I went to bed. Every morning I took our dogs through the campsite. We had to move to get to the bathroom or to go for fresh water. The beach was down a long boardwalk, the fallen firewood in the nearby woods. But walking was only the background. I ran down 400 foot sand bluffs with my boys and then made the agonizing climb back up in the shifting sand, pay back for the exhilarating speed down. I swam in crisp and clear waters, rollicking around near shore or diving to investigate shells and fish skeletons in deeper water. No sitting at the computer, not too much driving, no need to set aside special time to “exercise.” It was all the time there, part of what I was doing.

Girls closing math gap?: Troubles with intelligence #1

In a January 2005 speech, Harvard President Lawrence Summers provoked the proverbial firestorm by suggesting that women lacked the ‘intrinsic aptitude’ of women for math, science and engineering (story in the Boston Globe on the incident). Summers was merely stating out loud what many people believe: that inherent differences between men and women cause significant inequalities in aptitude for math (and presumably also for art history, Coptic studies, or cultural anthropology, but they usually get a lot less attention…).

A recent report in Science by Janet S. Hyde and colleagues, ‘Gender Similarities Characterize Math Performance,’ used a mass of standardized testing data generated under the No Child Left Behind program to compare male and female performance and found that the scores were more similar than different. The gap in average performance on math tests has shrunk significantly since the 1970s, disappearing in most states and grades for which the research team could get good data. According to Marcia C. Linn of the University of California, Berkeley, one of the co-authors of the study: ‘Now that enrollment in advanced math courses is equalized, we don’t see gender differences in test performance. But people are surprised by these findings, which suggests to me that the stereotypes are still there.’

From the way that this report has been discussed, it seems clear that the data has not settled this question in many people’s minds. Tamar Lewin of The New York Time covered the story in (‘Math Scores Show No Gap for Girls, Study Finds‘) provoking comments on a wide range of websites, including some who insisted that the team led by Hyde missed entirely the point being made by Summers or that Lewin had misread the study (some accusing her of feminist bias). In contrast, Keith J. Winstein of The Wall Street Journal focused not on the average scores, but on the results at the top end of the bell curve, writing, Boys’ Math Scores Hit Highs and Lows, which highlights the discussion of variance in boys’ scores.

Although I briefly want to go over the study and the way its being interpreted, I’m more interested in the shift in test scores over time because I think that the movements in these numbers, including gaps that disappear over time (or don’t), point to a basic problem in the tests themselves. Well, not a problem in the tests—they’re very sophisticated instruments for assessing certain kinds of performance on selected tasks—but rather with the common assumption about what these tests actually reveal and the nature of ‘math ability.’ For me, this larger point is more important for neuroanthropology because it applies to far more than just the ‘math gap.’
