Differences among people that include spatial skills, experience, and preferred strategies for wayfinding are part of what determines whether people get lost in buildings—and psychological scientists could help architects understand where and why people might get lost in their buildings, according to the authors of an article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science.
When you enter a new building, you build a cognitive map—a representation in your mind of the objects and locations in that environment. Success in navigating in the building may depend upon what information you put into the cognitive map. “For example, imagine visiting a new doctor’s office. You walk in the front door and find your way to the office, storing information about your route and the objects you encounter in your cognitive map. What is most interesting is how this information is then used to direct you back to the front door after the office visit.
“If you paid attention to the sequence of turns along the path, then you may have difficulty because you need to remember to reverse the sequence, and this becomes increasingly difficult as the number of turns increases. But instead, if you paid more attention to the objects that you passed, then you may navigate back to the front door by going from one familiar object to another without considering the sequence of turns. This strategy will work, as long as you can always see a familiar object. If you get lost and enter an unexplored part of the building, you will have difficulty finding your way back,” says Laura A. Carlson of the University of Notre Dame, first author of the article.
In some buildings, the strategies people use and the quality of their cognitive map may not matter very much. “If the building has an obvious structure, with long lines of sight, you won’t have to rely much on this internal representation of your path,” says Carlson.
Some buildings, on the other hand, make it difficult. Carlson and her coauthors, Christoph Hölscher of the University of Freiburg, Thomas F. Shipley of Temple University, and Ruth Conroy Dalton of University College, London, use the Seattle Central Library as an example. The bold building, designed by Dutch architect Rem Koolhaas, opened in 2004 and won awards for its design. But visitors complain that it’s difficult to navigate. People expect floors to have similar layouts, but the first five levels of the library are all different; even the outside walls don’t necessarily line up. Normally, lines of sight help people get around, but the library has long escalators that skip over levels, making it hard to see where they go.
For building users who may find navigating in new environments challenging, there are strategies that are helpful. “I used to worry when I explore a new city by myself that I would not find my way back to the hotel,” Carlson says. “However, this simple trick is effective. At each intersection where I need to turn, I spin around to see what the intersection will look like from my return perspective. That way, I will be able to recognize it from the other direction, and I can store that view also in my cognitive map.” This strategy also tends to work well for indoor navigation.
Architects, on the other hand, may be among the class of people with very strong spatial skills, because their craft requires numerous spatial transformations, such as needing to envision 3D space from 2D depictions. One unanticipated consequence of such abilities is that they may not be very good at taking the perspective of a user with poorer spatial skills, and therefore may not be able to fully anticipate where users may have navigational difficulties within their buildings.
Architects and cognitive scientists could learn from each other, Carlson says. Architects could explain how they use building features to encourage certain patterns of movement within the building, informing research on how people move through space; scientists could contribute data on how we build cognitive maps and what strategies different people use to find their way around.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
