What does the Von Restorff effect suggest?

The Von Restorff effect suggests that when presented with a group of similar items, the one that stands out as different or unique is more likely to be remembered. This phenomenon occurs because distinctiveness captures attention and creates a memorable impression, setting that item apart from the others. This principle is critical in UX design, where designers strive to make important features or calls to action prominent against a backdrop of uniformity, thereby enhancing user recall and engagement.

While the other options touch on aspects of memory and design, they do not capture the essence of the Von Restorff effect. The first option centers on the sequential order of items, which is not specifically related to uniqueness. The third option focuses on visual prompts, which contribute to memory retention but do not address the comparative memorability of unique items. The fourth option discusses the need for consistency in design recognition, which contrasts with the core idea of the Von Restorff effect, which emphasizes the impact of distinctiveness. Therefore, the chosen answer accurately encapsulates the concept.
