Taking in more information than what we can process slows us down. Be it a computer or human, no one can process beyond a specified level. If you open hundreds of apps in a computer, at same point of time it will stop working, slow down, or even crash. Same is with humans, every human has a defined cognitive load that the memory can process. Making anyone process more information than defined will result in cognitive overloading.
When it comes to designing a website or making your users stay on your website it has a major unnoticed role to play. Many times, we do everything in our control to make our website usable, accessible, and friendly to users, however we still get no success in figuring out what went wrong.
This one thing that we don’t take seriously is ‘Cognitive Overhead’. If your user is taking unnecessary actions to attain a specific goal in that case it will pose stress to users mind and user will not be able to handle this extra pressure and will ultimately go away.
Why need to take care of Cognitive Overhead? To be specific, cognitive overhead means the number of logical connections or jumps your brain has to make in order to complete a goal or to understand the things that he is looking at. So, we need to minimize this cognitive overhead because:
If your working memory receives more information than it can handle, it might lead to frustration, lack of concentration, compromised decision making ability, and also user might take more time to understand even a simple thing. This will lead to user go away from your website if your website poses cognitive overloading.
Cognitive overhead directly affects the user’s experience on your website. So, if your users are facing it, they are more prone to going away!
What causes Cognitive Overhead? If your users are asking these questions to themselves while navigating your website then there are possibilities of them facing cognitive overloading on your website.
- Where is the home button?
- Should I click on this? What would happen?
- How do I save this?
- Is this an advertisement or a genuine button?
- What should be done next?
- Will the data be gone if I refresh it?
And such questions like these. These questions put a load on user’s mind while using your website. If they are asking these questions then your website had a bad user experience as is not self explanatory. Users are not gonna like it.
What to do to Minimize Cognitive Overhead? So, if that’s the case you need to take some important measures to reduce the cognitive overhead in your website.
- Reduce Unnecessary Interactions
- Don’t Overstimulate the User
- Don’t Provide too Much Options to the UserJust like multiple actions, options too pose a cognitive load on the user and the user again lands up choosing nothing. When the user gets too many options, he will not be think of any one possible options and will increase the cognitive load.
- Avoid Too Much Content
- Non-User Friendly User Interface
What to do? Perform proper user interface testing and check if it is usable and non-distracting for the user.
To sum up, in order to reduce cognitive overhead, you need to:
- minimize the number of steps that should be taken
- focus on minimizing the time user spent in completing a task
- minimize number of unnecessary elements in a page
- avoid visual clutter like links, images, etc.
How to Check if You’ve Succeeded? Once you have taken care of precautions, read the guidelines, done your best to minimize the cognitive overhead. It’s time to find out if you’ve achieved success or not?
The best way to find that out is to get tested by the old, young, and drunk
Yes! If these three people are able to get the task done on your website, then you have achieved the success!
Also, ask the already existing users what your product does? That might seem a bit dumb, but you need to interact with your users to find out if they are able to do what you have intended from your product. Or are they using for some other thing? This will help you better understand the fields where you’re going wrong.
Takeaways Design your page in such a way that the user will feel very less stress on his brain while attaining a specified goal on your website. If he stresses too much, or faces cognitive overloading then he is more likely to distract from your website.
Every page’s design should be self explanatory, because you might never know from where your user is landing on your website. So make it easy for him to understand. If he is taking more and more steps to learn what your website does, he’ll no longer be interested in learning what it actually does.
Hope the ways that I have listed here helps you reduce cognitive overhead in your website. If you have more questions, drop us a comment below!
