As toddlers learn the names of colors, a remarkable transformation is taking place inside their heads. Before they learn their color names, they are better at distinguishing color categories in their right brain (Left Visual Field). In a sense, their right brain understands the difference between blue and green, even before they have the words for it. But once they acquire words for blue and green, this ability jumps over to the left brain (Right Visual Field).
Think about what that means. As infant brains are rewiring themselves to absorb our visual language, the seat of categorical processing jumps hemispheres from the right brain to the left. And it stays here throughout adulthood. Their brains are furiously re-categorizing the world, until mysteriously, something finally clicks into place. So the next time you see a toddler struggling with their colors, donât be like Darwin, and cut them some slack. Theyâre going through a lot.
