Children learn about how things are connected in the world, including why people do what they do and how things happen. They use both real and imaginary situations to figure this out. By studying how kids learn about cause and effect, researchers found that children can understand and separate actions based on patterns and reasons. They also found that kids can learn from watching others and that social situations can affect how they learn. This shows that children are good at figuring out why things happen and how they are connected, even in imaginary worlds.
