The more antennas you have and the bigger they are, the more signals you’ll pick up. Learning a new skill like chess-playing causes dendrites to grow. But that growth doesn’t stop once you’ve learned the game; interaction with people in challenging activities also fuels dendrite growth, and chess is a perfect example. Since the right hemisphere of the brain is responsible for creativity, it should come as no surprise that activating the right side of your brain helps develop your creative side. One four-year study had students from grades 7 to 9 play chess, use computers, or do other activities once a week for 32 weeks to see which activity fostered the most growth in creative thinking.
