Using the Von Restorff effect to capture user attention

The Von Restorff effect, also known as the isolation or bizarreness effect, explains how distinctive stimuli among similar ones are more likely to stand out and be remembered, as first documented by German psychologist Dr. Hedwig von Restorff in 1933. This phenomenon is useful in UX design to enhance user engagement by making specific elements, like sections or list items, more memorable without compromising overall visual consistency. Techniques such as "breaking the grid" and "blockifying" are employed to create standout content that maintains alignment and spacing for better scanability, while also addressing issues like banner blindness by placing ads in unexpected areas, thus increasing user interaction. The effect is also used in pricing strategies to highlight preferred options through framing and visual distinctions, though care must be taken to avoid misleading users. Ultimately, the Von Restorff effect should be applied in moderation, as excessive distinctiveness can negate its impact, reinforcing the principle that if everything stands out, then nothing truly does.
