The Age of Information puts knowledge at people’s fingertips. If you want to know how many ants live in a colony, you can ask Alexa or Google. Designing interfaces for users with 20 other tabs open on their browsers requires a higher level of technological savvy than needed years ago.
Cognitive overload happens when the human brain processes too much information at once. The result is poor memory and difficulty making decisions. Users may not realize they are suffering from mental exhaustion.
Tips to Negate Cognitive Overload Through Navigation
Your job as a designer is to be aware of the potential for cognitive overload before it happens and implement measures to prevent the problem. Navigation is an excellent first place to turn to when making a user-friendly site and helping people navigate the site’s hierarchy without becoming overwhelmed.
To fully understand how cognitive overload affects people’s decisions, you have to look at a study of brain surgeons and how what is going on around them impacts their cognitive function. The study presented trainee surgeons with several issues, tasks and distractions while tracking their brain activity through optical probes.
The idea is to figure out ways to overcome distractions and keep surgeons focused. However, the research is useful to UX designers by showing them how too many stimuli impact people’s brains–even those with extensive training and education. You don’t have to be a brain surgeon to reduce overload through better navigation structure.
1. Improve Color Contrast
With advances in 5G and cable internet, designers can add interesting design elements without fear of bogging down the system. Unfortunately, busy patterns can contribute to the busyness of a design and add to cognitive overload.
Instead, stick with solid colors or gradients, particularly on a page filled with images and other features. Keep a nice contrast between text and background so navigation is straightforward.
2. Keep It Simple
Stay inside the traditional confines of navigation. Most people expect to see the nav bar at the top of the page. You can put it vertically or horizontally as long as it is near the top. If you’re thinking about creating an animated structure where you click on map points to enter areas, reconsider. An already stressed user may bounce away rather than trying to figure out the navigational hierarchy.
In 2024, more businesses are embracing “less is more” designs with more negative space. Adding this extra white space around clickable elements makes the design more intuitive and reduces clutter.
3. Limit the Number of Categories
Have you visited a website with dozens upon dozens of categories? You likely found it difficult to find the page you needed. Look closely at your navigational hierarchy to improve navigation and limit mental exhaustion.
Rather than having dozens of options, shoot for five or six. Place anything related as a subcategory. You can also utilize mega menus to add visual cues and varied typography.
4. Ensure Responsiveness
Mobile traffic now accounts for 54.4% of site visits, making it crucial your site appears aesthetically pleasing for smaller screens. Spend time testing your site’s navigation for mobile users. Are the elements squished together, making them hard to read? Try different screen sizes.
Test all the links to ensure they work as expected. Cognitive overload sometimes occurs because users get frustrated at the multiple steps they must take to get a site to function as it should. Make sure everything works as expected and instructions are clear.
5. Prioritize Items
Consider the most essential elements on the page. How do different sections in the navigation tab align with the site’s goals? If you want the user to go on a journey, you must lay out a path or two and what touchpoints they’ll hit as they move through the sales funnel.
Prioritize the items that help you reach the goals you desire. If you want users to click on a link to subscribe to a newsletter, put the subscription link near the top of the page and within the nav bar.
6. Add Visual Cues
Reduce stress by pointing people to the next step. Visual cues can include arrows pointing to a specific link. You can also offset the page the person is on with a different color text or background. Underlines can highlight where the links are as the person moves their cursor across the page.
Anything you can do to add extra visual cues can improve the overall UX and remove the number of decisions a user must make.
Limit the Number of Decisions
When people feel overwhelmed by the number of choices, they may choose to make none. Adding too many elements will raise your bounce rate and push conversions lower. Pay attention to creating a navigational structure that is intuitive and simple. Your visitors will thank you, and your success will speak for itself.
