von Restorff Effect

The von Restorff Effect, also known as the Isolation Effect, predicts that when multiple similar objects are present, the one that differs from the rest is most likely to be remembered. This is because the distinct item stands out and captures our attention.

In design, this principle can be used to draw attention to important information or key actions. By making an element visually distinctive, we can increase the likelihood that users will notice and remember it. This can be achieved through variations in:

• Color
• Size
• Shape
• Position
• Motion

However, it's important to use this effect with restraint. If too many elements are emphasized, they will compete with each other and the effect will be diminished. Overuse of visual distinction can also lead to important elements being mistaken for advertisements.

When using visual distinction, it's also crucial to consider accessibility. Relying solely on color to communicate contrast can exclude users with color vision deficiencies. Similarly, using motion to draw attention can be problematic for users with motion sensitivity.
