Links on IQ, Learning, and Publishing

E-mails 'hurt IQ more than pot' (via Bruce Hoppe)

Workers distracted by phone calls, e-mails and text messages suffer a greater loss of IQ than a person smoking marijuana, a British study shows.

Fascinating comparison! I don't know about the effect on IQ, but distractions take away time from being, or becoming, competent at anything. (See The Expert Mind and Twitter, or How to Fritter your Life Away.) And again, it underscores the negative effects of multitasking on learning.

Scientific Journal to Authors: Publish in Wikipedia or Perish (via Stephen Downes)

Every day, hundreds of articles appear in academic journals and very little of this information is available to the public. Now, RNA Biology has decided to ask every author who submits an article to a newly created section of the journal about families of RNA molecules to also submit a Wikipedia page that summarizes the work. As Nature reports, this is the first time an academic journal has forced its authors to disseminate information this way. The initiative is a collaboration between the journal and the RNA family database (Rfam) consortium led by the Wellcome Trust Sanger Institute.

This is a great move toward making knowledge available to all. I hope other journals will follow suit.

How the City Hurts Your Brain

Now scientists have begun to examine how the city affects the brain, and the results are chastening. Just being in an urban environment, they have found, impairs our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory, and suffers from reduced self-control. While it's long been recognized that city life is exhausting -- that's why Picasso left Paris -- this new research suggests that cities actually dull our thinking, sometimes dramatically so.

"The mind is a limited machine,"says Marc Berman, a psychologist at the University of Michigan and lead author of a new study that measured the cognitive deficits caused by a short urban walk. "And we're beginning to understand the different ways that a city can exceed those limitations." ...

In a study published last month, Berman outfitted undergraduates at the University of Michigan with GPS receivers. Some of the students took a stroll in an arboretum, while others walked around the busy streets of downtown Ann Arbor.

The subjects were then run through a battery of psychological tests. People who had walked through the city were in a worse mood and scored significantly lower on a test of attention and working memory, which involved repeating a series of numbers backwards.

I wonder how urban effects compare with multitasking.

However, on the plus side:

Given the myriad mental problems that are exacerbated by city life, from an inability to pay attention to a lack of self-control, the question remains: Why do cities continue to grow? And why, even in the electronic age, do they endure as wellsprings of intellectual life?

Recent research by scientists at the Santa Fe Institute used a set of complex mathematical algorithms to demonstrate that the very same urban features that trigger lapses in attention and memory -- the crowded streets, the crushing density of people -- also correlate with measures of innovation, as strangers interact with one another in unpredictable ways. It is the "concentration of social interactions" that is largely responsible for urban creativity, according to the scientists.
