How the City Hurts Your Brain
Hugh Pickens writes "The city has always been an engine of intellectual life and the 'concentration of social interactions' is largely responsible for urban creativity and innovation. But now scientists are finding that being in an urban environment 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. 'The mind is a limited machine,' says psychologist Marc Berman. 'And we're beginning to understand the different ways that a city can exceed those limitations.' Consider everything your brain has to keep track of as you walk down a busy city street. A city is so overstuffed with stimuli that we need to redirect our attention constantly so that we aren't distracted by irrelevant things. This sort of controlled perception — we are telling the mind what to pay attention to — takes energy and effort. Natural settings don't require the same amount of cognitive effort. A study at the University of Michigan found memory performance and attention spans improved by 20 percent after people spent an hour interacting with nature. 'It's not an accident that Central Park is in the middle of Manhattan,' says Berman. 'They needed to put a park there.'"
I'm feeling very ambivalent about this study. Sure, walking down a busy street requires concentration. And? If you look at it this way, it's actively improving your concentration.
The truth is that most people work in office buildings that are not that busy, and they only spend a tiny fraction of their day in a busy and distracting environment. Honestly, this sounds like a study that was trying to find evidence that supports a predetermined conclusion.
XML is like violence. If it doesn't solve the problem, use more.
Yes it does. The ancient equivalent of a city would be on the veldt surrounded by predators. You are constantly on edge looking for the flash of colour which could mean you're on the menu. Your ears are straining to hear the danger signals through the constant noise. Constant exposure to such stress is very wearing and can result in various nervous malfunctions and lead to physical manifestations. Ever heard of hypertension ?
I recently (6 months ago) gave up driving a truck (18 wheeler for the US residents) because although the physical act of driving was easy, the mental stress of being abused by just about everybody else on the road led to me being pissed off the whole time. Once you get into that condition, you need serious training in Buddhism to learn to relax. I haven't had the training, and I still can't drive (even a car) without getting stressed almost immediately, and it has even affected me as a pedestrian. All this is happening to a person who in 2001/2002 drove across the US 3 times (FL -> WA, WA -> FL, FL -> CA) in a month and a half for fun, then drove almost all the way around Australia, then travelled all the way round NZ by bus. Hint: it's not the driving or travelling.
The human mind can't stand up to being attacked all the time. My condition is starting to become agoraphobic as it is impossible to go anywhere without encountering traffic. I recently spent time in Scotland, well away from large population centres, and it was like a large dose of valium. I was completely relaxed within a day or so. Unfortunately I still have to earn a living so moving there permanently isn't an option right now. And not having worked for 6 months means my savings are almost exhausted and my options are dwindling to zero.
Just because you don't notice the effect, it doesn't mean the problem doesn't exist. It is cumulative and one day it will hit you hard. Your brain gets used to the default state of mind being stress, and suddenly one day it gets stuck there. Very hard to get back from, and very hard to withstand real stress when it occurs, because you have so little energy left in reserve.
