How the User Thinks: Cognitive Psychology in UX/UI Design

Every time you open an app or visit a website, you’re making dozens of small decisions without even realizing it. You decide where to click, where to look, whether to stay or leave. These actions are driven by complex cognitive processes. As a UX/UI designer, understanding the basics of psychology can be your superpower to create intuitive, user-friendly, and effective designs.

Cognitive Psychology: The Foundation of UX Design

To dive into the psychological principles that shape user behavior, let’s start with some insights from cognitive psychology, as highlighted in the article A Few Things Your UX Designer Can Learn From Your Shrink.

Cognitive Load: The Burden of Decision-Making

What is Cognitive Load?

Cognitive load refers to the amount of mental effort required to complete a task. When designing interfaces, it’s crucial to minimize this load to make the user experience smoother.

Hick’s Law

Hick’s Law, mentioned in Cognitive Psychology and Emotions in User Interface Design, states that the time it takes for a user to make a decision increases with the number of available options. This means too many choices can overwhelm users, leading to higher cognitive load and potentially driving them away.

Practical Application

The Paradox of Choice: Too Many Options Can Be a Bad Thing

The Paradox Explained

The paradox of choice suggests that while having more options might seem beneficial, it can actually lead to decision paralysis. This concept is closely related to cognitive load, as too many choices can confuse and frustrate users.
