Unlocking User Behavior: 4 Powerful Laws and Effects

The Von Restorff Effect: Standing Out from the Crowd

In 1933, German psychiatrist Hedwig von Restorff discovered that when multiple similar objects are presented together, the one that differs the most is more likely to be remembered. This effect has significant implications for product design. By making the most important information or action visually distinctive, you can draw users’ attention and improve their experience.

By using a visually distinctive design, such as a prominent button, you can guide the user’s attention towards the most important action.

Miller’s Law: The Limits of Multitasking

In 1956, George Miller found that people can only hold about seven pieces of information in their immediate memory. This law highlights the importance of breaking down complex tasks into smaller, manageable chunks. By doing so, you can reduce cognitive overload and help users focus on what matters most.

1. Break down complex tasks into smaller steps
2. Use clear and concise language
3. Avoid overwhelming the user with too much information

Hick’s Law: The Paradox of Choice

In 1952, psychologists William Hick and Ray Hyman discovered that the more options people have, the longer it takes them to make a decision. This law has significant implications for product design. By limiting the number of choices and providing clear defaults, you can simplify the decision-making process and reduce user anxiety.

• Limit the number of options to 3-5
• Provide clear defaults
• Make it easy to undo or change decisions

The Aesthetic-Usability Effect: The Power of Beauty

In 1995, researchers at the Hitachi Design Center found that users perceive beautiful designs as more usable. This effect highlights the importance of aesthetics in product design. By creating visually appealing products, you can improve user satisfaction and increase engagement.
