Spatial Orientation and the Brain: The Effects of Map Reading and Navigation by Rebecca Maxwell.
From the post:
The human brain is a remarkable organ. It has the ability to reason, create, analyze, and process tons of information each day. The brain also gives humans the ability to move around in an environment using an innate sense of direction. This skill is called spatial orientation, and it is especially useful for finding routes in an unfamiliar place, following directions to another person’s house, or making a midnight raid of the refrigerator in the dark. Spatial orientation is crucial for adapting to new environments and getting from one point to another. Without it, people will walk around in endless circles, never being able find which way they want to go.
The brain has a specialized region just for navigating the spatial environment. This structure is called the hippocampus, also known as the map reader of the brain. The hippocampus helps individuals determine where they are, how they got to that particular place, and how to navigate to the next destination. Reading maps and developing navigational skills can affect the brain in beneficial ways. In fact, using orientation and navigational skills often can actually cause the hippocampus and the brain to grow, forming more neural pathways as the number of mental maps increase.
A study by scientists at University College in London found that grey matter in the brains of taxi drivers grew and adapted to help them store detailed mental maps of the city. The drivers underwent MRI scans, and those scans showed that the taxi drivers have larger hippocampi when compared to other people. In addition, the scientists found that the more time the drivers spent on the job, the more the hippocampus changes structurally to accommodate the large amount of navigational experience. Drivers who spent more than forty years in a taxi had more developed hippocampi than those just starting out. The study shows that experience with the spatial environment and navigation can have a direct influence on the brain itself.
However, the use of modern navigational technology and smartphone apps has the potential to harm the brain depending on how it is used in today’s world. Map reading and orienteering are becoming lost arts in the world of global positioning systems and other geospatial technologies. As a result, more and more people are losing the ability to navigate and find their way in unfamiliar terrain. According to the BBC, police in northern Scotland issued an appeal for hikers to learn orienteering skills rather than relying solely on smartphones for navigation. This came after repeated rescues of lost hikers by police in Grampian, one of which included finding fourteen people using mountain rescue teams and a helicopter. The police stated that the growing use of smartphone apps for navigation can lead to trouble because people become too dependent on technology without understanding the tangible world around them.

Other studies demonstrate that men and women develop different methods of navigating and orienting themselves to the spatial environment because of differences in roles as hunters and gatherers. This could explain the reason why men get lost in supermarkets while women can find their way around in minutes. Research done at Queen Mary, University of London demonstrated that men are better at finding hidden objects while women are better at remembering where objects are at. In addition, Frank Furedi, a sociology professor at Kent University, states that women are better at making judgment calls while men tend to overcomplicate the most basic navigational tasks.
The use of map reading and navigating skills to explore the spatial environment can benefit the brain and cause certain areas to grow while the use of modern technology for navigation seems to only hinder the brain. No matter which strategy men and women use for navigation, it is important to practice those skills and tune into the environment. While technology is a useful tool, in the end the human brain remains the most sophisticated map reader.
Very interesting post on the impact of GIS systems on the human brain and gender differences in methods of navigation.
Question: Gender differences in navigation are more than folktales so why do we have uni-sex data navigation interfaces?
