This article explains the the Word Superiority Effect. The Word Superiority Effect is an idea about language. It is said that it dates back to the 1800s. The hypothesis behind it is that people tend to recognize words quicker when they are presented in a recognizable word than they are in a unrecognizable work. Doctors use The Word Superiority Effect when testing their patients’ eye sights. When they are looking through that tube, they see letters that do not form any words. That way, the patients have to focus on the letter they are being presented, rather than use context clues to try and figure it out.
