Kiki-Bouba theory is a concept in psychology that's both fun to say and easy to understand. It's a theory that explores the relationship between the shapes of objects and the sounds of words. Imagine you have two made-up words: "Kiki" and "Bouba." Now, picture two shapes - one is all pointy and jagged, and the other is smooth and round. It's a fun and creative way to show how our brains work in mysterious and intriguing ways, connecting language and perception in a fascinating dance of cognition. So, next time you come across something that makes you think of "Kiki" or "Bouba," you'll know why it feels just right!
