Is Our Reliance on GPS Shrinking Our Brains? (heraldnews.com) 121

Posted by EditorDavid from the bad-directions dept.
"Neuroscientists can now see that brain behavior changes when people rely on turn-by-turn directions," says science writer M.R. O'Connor, citing a study of personal GPS devices co-authored by Kent-based cognitive neuroscience researcher Amir-Homayoun Javadi: What isn't known is the effect of GPS use on hippocampal function when employed daily over long periods of time. Javadi said the conclusions he draws from recent studies is that "when people use tools such as GPS, they tend to engage less with navigation. Therefore, brain area responsible for navigation is less used, and consequently their brain areas involved in navigation tend to shrink."

How people navigate naturally changes with age. Navigation aptitude appears to peak around age 19, and after that, most people slowly stop using spatial memory strategies to find their way, relying on habit instead. But neuroscientist Veronique Bohbot has found that using spatial-memory strategies for navigation correlates with increased gray matter in the hippocampus at any age. She thinks that interventions focused on improving spatial memory by exercising the hippocampus -- paying attention to the spatial relationships of places in our environment -- might help offset age-related cognitive impairments or even neurodegenerative diseases. "If we are paying attention to our environment, we are stimulating our hippocampus, and a bigger hippocampus seems to be protective against Alzheimer's disease," Bohbot told me in an email.

      Before GPS, when I lived first in LA and then in the Bay Area, I used to use AAA maps. Those were pretty handy: I'd check out in advance where I needed to go, and followed it accordingly. I knew quite a number of cities like the back of my hand, having driven extensively in those places.

      I got my first car w/ built in GPS 4 years ago, and it has been really useful in Charlotte, Atlanta and now Northern Virginia. Since roads on the East coast are less gridlike than on the West, this has been useful, particularly while I changed cities: I'm not sure that it would have been easy following maps. My only complaint is any map upgrade on the car is overpriced at $500, which is stupid given that the newer cars have automatic connection modes to Car Play or Android Auto.

    When I was about four years old (1965?), I stood in the back seat of the Dodge and watched my father figure out how to get to Maine on a paper map. I remember thinking, "I'm going to have to do that when I grow up... this looks important."
    After that day, in school and out, I was interested in maps. As soon as I started driving, I would take my battered Saab 96 anywhere the roads led: Provincetown, Tucson, wherever. Later in life, I drove deliveries, and spent a few years driving a taxi. I was known for my ability to get to places much more quickly than expected, only partly because of my heavy right foot.

    ... at least, for me anyway.

    Back when I was growing up in the late 1980s/early 1990s, I had this precocious curiosity around navigation: my father was a civil engineer with the provincial Department of Public Works based out of Pietermaritzburg, and he'd often need to perform site inspections in far-off rural parts of the province, and often he'd take me (at the ages of 4-5, before I'd started primary school) along for the ride. I always wanted to know where on the road we were, where we were going, and how much further until we could stop for lunch (this was important at age 5!), and I'd "borrowed" (read: expropriated) the road maps from my father's study and taught myself what they meant and how to use them, but I could never read them in the car without getting violently carsick around 15 seconds later.

    Thus, I very quickly gained the ability to memorize the paper maps, and so whenever we were on the road, I would then know exactly where we were, which route we should take, how much further we should go, and where all the rest stops were. Totally from memory. I became good enough at this so that, by age 8, I had officially been promoted to family navigator on our road trip holidays.

    I'm now 34, moved from South Africa to New Zealand, and paper replaced digital (mostly: I still keep paper maps for a fallback) but I still navigate this way. When I need to navigate to somewhere new (and since I'm a fairly new immigrant, this currently happens a lot!), I'll pull out a map (be it paper or OpenStreetMaps) before I head off, look at where I need to go, and then apply this to my pre-existing knowledge of the area. This technique of mine still hasn't failed me.

    I do have a GPS application on my mobile device and will load it up, but for me, it's far more about OpenStreetMaps quality control (I'll observe what the GPS is doing and then use this to improve OSM quality on the route I've been along) and far less about navigation itself.
