Visual attention allocation induced by landmarks can advance the spatial navigation performance of older adults
This study demonstrates that adding text-labeled landmarks to public maps enhances spatial navigation performance in adults aged 55 and older by guiding visual attention allocation, strengthening route memory, and improving decision-making accuracy in virtual environments.

Getting lost is a quiet crisis of aging. For many people over fifty-five, the simple act of finding a way from a bus stop to a grocery store, or navigating a hospital corridor, can become a source of deep anxiety. This struggle is not just about memory; it is about how the brain processes space. As people age, the ability to perceive the world in three dimensions and to remember the layout of a route often fades. This decline in spatial navigation is a major public health issue because it can strip away independence, keeping people from leaving their homes and participating in their communities. While maps are a common tool to help people find their way, the standard maps found in public buildings are often abstract collections of lines and shapes that can be confusing, especially for those whose visual attention is already struggling to keep up.
Researchers at China Medical University set out to see if a small change in how these maps are designed could help. They focused on the idea that older adults might not be failing because they cannot learn a route, but because they are not seeing the right clues. In a standard map, a landmark like a fountain or a bus stop might be represented by a small, unlabeled icon. The team wondered if adding clear, large text labels to these landmarks would act as a beacon, guiding the eye and the mind. To test this, they did not just ask people what they thought; they watched exactly where the participants looked. Using a specialized eye-tracking system, they could measure every moment a person's gaze landed on a map, distinguishing between a quick glance and a focused look that indicates the brain is processing information.
The study involved seventy-eight adults aged fifty-five and older, recruited from community centers and retirement homes. The participants were divided into two groups. Both groups were asked to learn a specific route on a two-dimensional map of a virtual town. The route was marked with a red line, starting at one point and ending at another, passing through several intersections. The control group saw a standard map where the landmarks—a fountain, an advertising board, and a school bus station—were visible but had no text labels. The experimental group saw the exact same map, but with the names of these landmarks written clearly in red text right next to them. After studying the map, every participant entered a computer-generated three-dimensional version of that town. They had to walk the route they had just memorized, making decisions at every intersection to stay on the correct path.
The results showed that the text labels made a significant difference in how the participants used their eyes and, ultimately, how well they navigated. When looking at the map, the group with the labeled landmarks spent much more time looking at the landmarks themselves. Their eyes were drawn to the text, and they looked at these spots more often than the group with the unlabeled map. This extra attention during the learning phase translated directly into better performance later. When the participants walked through the virtual town, the group that had studied the labeled map made far fewer wrong turns. While the control group made errors at a rate that suggested they were struggling to recall the path, the experimental group was much more accurate. In fact, the accuracy of the labeled group was so high that their performance no longer seemed to depend on their age or their general cognitive scores. The labels seemed to level the playing field, allowing those with lower cognitive scores to navigate just as well as those with higher scores.
The researchers also looked closely at the nature of the participants' eye movements to understand what was happening in their minds. They categorized the way people looked at things into different types of attention. A very brief look, lasting less than a tenth of a second, was considered an unconscious glance that didn't really register. A slightly longer look, up to half a second, was an ambient scan, where the brain is taking in the general scene. A longer, focused look, lasting up to a second, indicated that the person was actively making a decision or processing specific information. The data revealed that the group with the text labels spent more time in these active, decision-making states when they looked at the landmarks. They were not just glancing; they were using the text as a cue to confirm their location and plan their next move. In contrast, the group without labels spent more time in that brief, unconscious state, suggesting they were not fully engaging with the landmarks as useful tools.
This study suggests that the problem for many older adults is not necessarily a lack of ability to learn a route, but a lack of effective cues to trigger that learning. By simply adding text to the landmarks on a map, the researchers created a visual anchor that helped older adults allocate their attention more efficiently. The text acted as a guide, pulling the eye to the important parts of the map and helping the brain form a stronger memory of the route. This finding is particularly important because it offers a solution that is low-cost and easy to implement. It does not require expensive technology or complex training; it only requires a change in how information is presented. For public spaces like nursing homes, train stations, and libraries, where wayfinding is critical for safety and independence, this simple design tweak could make a profound difference. It suggests that by making the environment more readable, we can help older adults maintain their freedom to move through the world with confidence.
