1999. "The Matrix. When this cult sci-fi action film was released, many people, stunned by the film, remembered the episode with the "girl in red". In the crowd dressed in "all shades of black", only one person stands out - a blonde in a revealing dress. The sharp contrast with the monochrome clothing of the pedestrians emphasises the gap between visibility and reality. At first, the protagonist focuses all his attention on her. And makes a mistake.
We always notice something unusual, different, different from others. Objects that stand out are easier to remember. A person pays attention to everything that stands out from the crowd and remembers what is different from others. Our brains always need a point of comparison. Perhaps this is how ancient people responded to danger, instinctively highlighting the strange and unusual.
The ability of human memory to remember information and images that are as different as possible from their surroundings is called the Von Restorff effect, or the isolation effect. The greater the difference, the better the effect. Unconsciously, we use it all the time in our communication. You will immediately notice a red apple in a bunch of green apples. Highlight the bold text and that's the Von Restorff effect for you!
