Is technology changing our brains? A new study by UCLA neuroscientist Gary Small
adds to a growing body of research that says it is. And according to Small's new
book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a
dramatic shift in how we gather information and communicate with one another has
touched off an era of rapid evolution that may ultimately change the human brain
as we know it. "Perhaps not since early man first discovered how to use a tool
has the human brain been affected so quickly and so dramatically," he writes.
"As the brain evolves and shifts its focus towards new technological skills, it
drifts away from fundamental social skills."
The impact of technology on our circuitry should not come as a surprise. The
brain's plasticity—it's ability to change in response to different stimuli—is
well known. Professional musicians have more gray matter in brain regions
responsible for planning finger movements. And athletes' brains are bulkier in
areas that control hand-eye coordination. That's because the more time you
devote to a specific activity, the stronger the neural pathways responsible for
executing that activity become. So it makes sense that people who process a
constant stream of digital information would have more neurons dedicated to
filtering that information. Still, that's not the same thing as evolution.
Public Stiky Notes
What causes evolution is selective genetic traits being propogated over generations. Its a nice social psychology study, but provides no evidence to support its claims of evolution. It may prove that the brain is already powerful enough to reconfigure based on patterned usage. It is most definately not evolution.
Operating with data in this manner in such a short period of time allows a faux expertise to develop - relevant bits of information all at hand allow for an informed decision to be made. As the mind grows accustomed to this behaviour, it sucks information out of whatever is available and works with it as best it can.
Practice makes perfect!
