GPS Negatively Impacts Spatial Memory

Published on by Jonathan Crowe

Rebecca Solnit points to a 2020 study that attempts to measure the impact of using GPS navigation devices on our spatial memory. After assessing 50 drivers, researchers found that drivers with more GPS experience had worse spatial memory when navigating without GPS. But more significantly, it’s a longitudinal study: 13 of the participants (admittedly a small sample) were retested three years later, and greater GPS use correlated with a steeper decline in spatial memory.

This is a single study, and a small sample, so I’m hesitant to draw firm conclusions. And in any case it’s not necessarily a surprising conclusion: the more you rely on a tool, the less able you are to do without it. Well, yes. When we talk about how GPS is destroying our ability to navigate or read a map, there is a presumption that this is an objectively bad thing. Except that I’ve encountered too many people who couldn’t navigate their way out of a bag before GPS. A lot of people who let their GPS receivers get them lost were, I think, pretty good at getting themselves lost without it.

The question isn’t whether GPS use atrophies an individual’s ability to navigate: that’s like worrying that a calculator reduces your ability to do sums in your head, or that a word processor excuses you from knowing how to spell. Of course it does. Those of us who are good at navigation (or sums, or spelling) and think an important skill is being lost will clutch our pearls, but making something easier also makes it more accessible. The question is whether people are, on balance, at a societal level, getting lost less often. That’s not a question neuroscience can solve, nor something you can test with an fMRI. I’m not sure how to measure it, or even if it can be measured. But I’d love to find out.

New Osher Exhibition: Vacationland

Vacationland: Mapping History in Maine, the Osher Map Library and Smith Center for Cartographic Education’s latest exhibition, “looks at tourism through the lens of travel and transportation, quite literally the mapping of tourism in Maine from the mid-19th century to the mid-20th century. This exhibition invites you to think about the changing landscape interventions created by and for tourists, as well as the impact such changes had on people living in Maine year round, and upon the environment.” This exhibition opened on 15 June and runs until 11 October; reservations required for social distancing reasons to visit the gallery in person. It’s not yet online; the Osher usually gets an online version up a little later on.

Review: The Cartographers

Published on by Jonathan Crowe

Book cover: The CartographersI bet you’ve been wondering what I thought about Peng Shepherd’s novel The Cartographers (William Morrow/Orion, March 2022). After all, it’s a literary fantasy about maps: is it even possible for a book to be more relevant to my interests? Well, wonder no longer, because I’ve reviewed it for Strange Horizons.

This piece is a little bit different from the usual review, in that it examines The Cartographers in the context of mysteries and fantasy that deploy similar map tropes, as well as the idées fixes our culture has about maps. As I write in the review, there’s an awful lot for me to unpack:

I have been writing about maps for nearly two decades, and in that time I have encountered many works of fiction that incorporate maps and map tropes into their storytelling, whether as paratexts or as plot elements, and I have never encountered a story, at any length, as thoroughly encompassed by maps as The Cartographers. It’s not just that almost every character in the book works with maps in some fashion, whether as a cartographer, artist, librarian, map dealer, or technician. Nor are maps just a plot point—they are the point. The Cartographers is a Stations of the Map: its pilgrimage follows a path that touches on so many aspects of maps and mapmaking, from academic cartography to fire insurance maps. It spends time on the purpose and meaning of maps: it aspires to an almost Socratic dialogue. It deploys familiar fantasy genre tropes about maps. But it’s structured as a mystery novel, and opens with a murder.

The World in Maps: New Exhibition at Yale’s Beinecke Library

Published on by Jonathan Crowe

An exhibition at Yale University’s Beinecke Rare Book and Manuscript Library opens this Friday: The World in Maps, 1400-1600.

This exhibition presents many of the most historically significant manuscript maps from the late medieval and early modern period from the Beinecke Library’s vast collection of maps. It is focused on portolan charts—large, colorful charts that showed the shoreline of the Mediterranean, and were used by sailors to navigate from port to port. These maps were crucial to the expansion of European trade in the fiftieth and sixteenth century. Yale University Library has one of the most significant map collections of this period and owns some unique items not found in any other collection. […]

This exhibition presents maps from several different historical groups and demonstrates how maps functioned to place people within a larger world context. While primarily focusing on European maps, it also includes Middle Eastern and Asian world maps to illustrate common elements and also highlight significant differences. In addition, the exhibition presents some map forgeries and how they were determined to be fakes using scientific and historic analysis.

On that last point, yes, the Vinland Map will be a highlight of the exhibition, as will the Aguiar and Beccari portolan charts, the Martellus world map, and the Abenzara map.

The exhibition runs until 8 January 2023. Lectures will be taking place in the fall.

Allegorical, Dissected and Spiritual

Published on by Jonathan Crowe

Writing in Commonplace, Janet Moore Lindman looks at the use of spiritual maps in early America, focusing in particular on a curious 1794 combination of dissected map (a jigsaw-like map puzzle) and allegorical map (where  virtues or vices or other abstract ideals are depicted as countries on a map) produced for the education of Quaker children.

The production of Dillwyn’s allegorical map was unusual for Friends who disdained the visual arts as worldly and pernicious. Quaker abhorrence of art makes this image singular at the same time it demonstrates their adaptability to a new mode of educational instruction. Yet Quaker plainness was retained. Dillwyn’s map made use of little color, had few illustrations, contained no human figures, and relied heavily on the written word to convey meaning.
