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.’
