M. R. O’Connor’s book Wayfinding: The Science and Mystery of How Humans Navigate the World came out in April from St. Martin’s Press. Not coincidentally, she’s published a couple of pieces on the subject of that book, both of which focus on humans’ ability to pay attention to their surroundings, and the effect that relying on GPS directions might have on that ability. In a piece for Undark, O’Connor argues that “our unshakeable trust in GPS,” which traces itself back through hundreds of years of believing in the infallibility of maps, gets us lost because we’re relying on the device rather than our senses. Her piece for the Washington Post focuses on the role of the hippocampus in navigation and spatial awareness, and the need to exercise that part of the brain.
A recent study suggests that there’s a link between a good sense of smell and a good sense of direction, with the same brain areas being implicated in both abilities. As someone who has difficulty getting lost who also has a precise sense of smell, I resemble this study, which was published at Nature Communications. [Boing Boing]
