Sara saw seven sharks while swimming. now how many s is in this sentence?

In the world of neuroscience, this is called “contextual interference.” When you’re in a situation where there are many s’s together, it can be difficult to process them all. The more semantically and visually different letters you see around an S, the easier it will be for your brain to distinguish that letter from others on the page or screen. This phenomenon has practical implications for digital marketers who want their readers to understand what they’ve written- whether its blog posts or emails about new products and services. One way we use this principle at Brainlabs Marketing is by making sure our headlines have plenty of other words around them so they stand out as clear calls-to-action that get read without any confusion.
