导读
这篇论文研究习惯性使用 GPS 导航是否会削弱人在自主导航时的空间记忆。研究比较不同 GPS 使用习惯者在自我引导导航中的空间记忆表现，结论指向习惯性 GPS 使用与空间记忆下降存在关联（标题表述为负面影响）。
HN 关注点：HN 读者围绕亲历争论 GPS 的便利与代价：它降低陌生环境压力，但可能让人更少练习认路、记路名和脑中规划路线，并延伸到户外导航安全建议。

支持把地图当静态地图自行规划路线可保持方向感；Google Maps 的信息展示不利于这种做法，作者因此转用 OSM 并故意探索陌生路线。
我只把 Google Maps 当真正的地图用，而不是导航：用它确认位置、看道路、看目的地，然后自己在地图上规划路线。这样即使不用地图 app 也能保持方向感，因为我已经知道哪些路和哪些路相交、在哪、怎么从 A 到 B。可惜 Google Maps 处处阻碍这种用法，比如不放大到离谱级别就不显示街道名（有时放大了也不显示），也不显示哪些是单行道、哪些路能骑车。所以我主要用 OpenStreetMap 这类真正的地图。另外，如果去某地时间充裕，我会故意迷路，走不认识的街，再查地图确认自己在哪——这对发现隐藏小路和捷径很有用。

I just use Google Maps as actual map, not as navigation. That means I use it to find where I am, look at the roads, and look at where I want to go, and plan the route on the map myself. This helps me to stay oriented when I'm not using a maps app as well, because I already know which roads intersect with which, where, and how to take them to get from A to B. Sadly, Google Maps does everything they can to prevent you from doing this, e.g. not showing street names at all unless you zoom in to ridiculous levels (and often not even then) as well as not showing you which roads are one-way, which roads allow bicycles, etc. That's why I mostly rely on Open Street Map and similar actual maps. Also, if I've got additional time to get somewhere, I'll get lost on purpose, taking roads I don't know yet, then looking at the maps to figure out where I am (which is super useful to discover hidden paths and shortcuts).
质疑GPS 极大降低陌生地点导航压力、提升效率，实际价值远超传统导航技能。
作为经常搬家的人，GPS 导航改变了生活。你可以极快、几乎无压力地融入当地机会。我妻子开车时需要改道，我们俩都没去过新目的地。我只是把新目的地分享到她车上的导航系统，她全程没把手离开方向盘，而我们能在离目的地 30 英里时就规划出误差一分钟内的到达时间。我懂陆地导航、天文导航、LORAN，一度还懂 GPS 的数学……但实际生活中 GPS 就是魔法。真正改变游戏规则的是它降低了陌生环境中的压力。

As someone who moves frequently, GPS navigation is life-changing. You can snap into the local opportunities with incredible speed and virtually no stress. My wife needed to reroute while driving. Neither of us had ever been to the new destination before. I just shared the new destination to her car's nav system. She never took her hands off the wheel, and we could all plan our arrival to within a minute from 30 miles out. I know land nav, celestial navigation, LORAN, at one point I knew the math for GPS. yada yada. As a practical matter, GPS is magic. It's the reduction of stress in new places that is such a game changer.
亲历亲历印证：只用 GPS 会延缓路名和脑中路线规划的学习，但便利性让作者觉得不必刻意避免，且 GPS 的俯视图还能训练导航能力。
非常可信，我自己也注意到这个效应。搬到新地方后，如果我只靠 GPS 到处走，要花几个月才能记住路名并在脑中规划路线；而如果只在真正迷路或不确定时才看 GPS，几天到几周就能做到。问题是，何必呢？我总是带着手机。在离家几英里内我能自己找到路，但可能多花一点时间，路线也不是最优，还有遇上突发交通变化的风险。在完全不熟的地方，空间记忆无关紧要，反正还是得靠 GPS。实际上我觉得 GPS 让我成为更好的导航者：俯视视角像电子游戏，而我大量练习过看 2D 地图并把它对应到 3D 环境。

Very believable, I've noticed this effect myself. When I've moved to a new area, if I use GPS exclusively to get around it takes me months to learn the names of roads and do "route planning" in my head. Versus very quickly, within a few days/weeks if I only refer to GPS when legitimately lost or unsure. The thing is, why bother? I always have my phone. If I'm within a few miles of my house, I can figure out where I'm going, but maybe it takes me a little longer, and I don't come up with the optimal route, and now I and have the risk of getting caught in unexpected change in traffic patterns. If I'm somewhere unfamiliar, spatial memory is irrelevant and I have to rely on it regardless. Actually I feel like GPS makes me a better than navigator. Having the "top down" view makes it feel like a video game, and that's one area where I have a ton of practice looking at a 2D map, relating it to 3D environment, and so on.
补充户外安全建议过度排斥手机 GPS、神化地图指北针；对多数徒步者，离线路线+电量+备用+告知行程更实用。
我经常在苏格兰户外、徒步、登山，标准建议对技术如此恐惧，让我很沮丧，而且我认为相当危险。几乎所有向导和山地救援人员都会建议人们携带地图和指北针并会使用，说带 GPS 的手机只作备份，却不给任何使用建议。用地图和指北针导航是很难的技能，需要大量练习；苏格兰的 Munros 经常遇到几乎零能见度，即使最老练的导航者也会吃力。接受这些建议的人几乎都不是想真正“导航”，而是想在行程中跟着一条路线走；只要有人给出正确指导，用手机做这件事非常简单。当人们把合适路线下载到手机以便离线使用、确保电量充足并带合适备用设备、告知他人路线和预计返回时间，他们已覆盖了导航方面让人陷入麻烦的大多数情况。可他们却常被那些似乎是对导航有深厚兴趣的热情志愿者告知要带地图和指北针。

I spend a lot of time outdoors / hillwalking / mountain climbing in Scotland and it is quite fustrating and in my opinion quite dangerous how technophobic the standard advice given is. Almost universally guides and mountain rescue people will advise that people should carry and have knowledge of how to use a map and compass, inform that a phone with GPS is to be used as a backup with no advice given on how to use it. Navigating with a map and compass is a difficult skill that takes a lot of practise, Scottish munros are very regularly subject to almost zero visibility where even the most advanced navigator would have difficulty. Almost none of the receipients of this advice actually want to navigate, they want to be able to follow a route for duration of their journey. A task that is very simply done with a phone if someone has been given the correct instruction. When people have an appropriate route downloaded on their phone to work offline ensuring they have enough charge and suitable backup devices alongside told someone their route and expected time of return they have covered most of the situations that get people in trouble in terms of navigation. Instead they are routinely told to bring a map and compass by people who generally seem to be enthusiastic volunteers who have a deep interest specifically around navigation.
