Wubi effect is a special name for something that happens when people start to get used to things around them. Imagine a little kid just starting school. At first, the school seems very large and scary, and the child might feel overwhelmed and nervous. However, as time goes by and the child gets used to being there, the school starts to feel smaller and more familiar. The child might not feel as scared anymore because they know their way around and have made friends with their classmates.
This same thing can happen for people who travel to new places. When they first arrive, everything seems foreign and exciting, but after a while, the new place starts to feel more like home. This is the Wubi effect. The longer someone is in a new place, the more familiar it becomes, and the less excitement they might feel. It's like when you get a new toy, at first it's the best toy ever, but after a while, it's just a regular toy.
Scientists study the Wubi effect because it can affect how people perceive the world around them. When things become too familiar, people might not notice new and exciting things as much. This is why it's important to keep exploring and learning new things, even if we think we know everything there is to know about a place. So remember, just because something seems ordinary and familiar, doesn't mean it's not still exciting and interesting!
