Use the Von Restorff effect to highlight important information
It is useful to have the Von Restorff effect in mind when you want to have an impact on the choice of the user. According to the Von Restorff effect the user notices things that are different than other similar options.
A good example of this effect is the text in CAPITAL LETTERS. You noticed the capital letters and remember the words that are in capital letters better than the other. Important options should be different than other similar options so user take better notice of them.
Get to the core of the issue with Occams razor
Occams razor is a general rule of thumb that the simplest solution is probably the best. Keep the interface simple and clear. Each solution should require a minimum thinking period and that the fewest actions. Such a design creates a smoother and more convenient experience for the user.
Tell the user what information is relevant
Some information is more important than other. With the design of UI, we must take care to position the important information where they have the most impact. The first and last item is the easiest for users to remember.
These effects concern not just a list in a text but rather how users experience the UI. Keep this effect in mind with the design of the interface and make sure that the information is set put in order of importance to allow the user intuitively to understand the importance of the information.
Teach your users using Hick's law
The UI needs to show your users a clear and obvious choice. Avoid complicated coices and options. Hick's law stipulates that the act of choosing takes longer, the more options you have.
Keep the user's choice at a minimum with few, simple and clear options. If it is not possible to reduce the number of features try to divide them up into steps.
Here is a little experiment. List seven names. You can do that without much struggle. But if what if you list seven favorite actors or athletes? It's far easier, right?
The law of Millers says that we can only store seven objects in short-term memory, but our mind can remember a lot of similar data if we group them together. Therefore, you struggle to remember just whatever names you can think of while you list your favorite actors with ease.
UI must reflect this and present the information in clear groups. Thus, the user can easily register the knowledge and group it.
