Sometimes we see faces that aren’t really there. You may be looking at the front of a car or a burnt piece of toast when you notice a face-like pattern. This is called face pareidolia and is a mistake made by the brain’s face detection system.
But it’s an error that can help us understand the workings of the human mind. A recent study has argued that having a baby may affect this aspect of our brains, suggesting it may vary across our lifetimes.
