10 Weird Ways Your Brain Is Tricking You
Our brain decides how we perceive everything around us. It informs our decisions, guiding us carefully through the fog that is the world around us . . . except for when it lies to us. You see, our brains are fickle friends and love to play games. Often, what we think is true is actually just our brains messing with us.
Have you ever repeated a word several times and found that, after a while, it started to lose meaning? If you have, you needn’t worry—scientists have studied this phenomenon and call it semantic satiation. Studies found that as you repeat a word, your brain becomes satiated and you start to get confused about what the word even means. You see, normally when you say a word (e.g., “pen”), your brain finds the semantic information for a pen and connects the two things together. However, counter-intuitively, if you repeat the word a number of times in quick succession, your brain becomes less able to connect it with that semantic information each time.
Researchers have found practical uses for this information beyond just amusing themselves with how easily we trick ourselves—by using semantic satiation in a controlled environment, they have been able to help those who stutter, and in one case were able to help someone with coprolalia, the uncontrollable cursing sometimes associated with Tourette’s syndrome, by having him repeat his favorite curse words over and over.
