A child in the preoperational stage insists that their toy dinosaur is happy because it has a big smile painted on it. Which category best describes this behavior, and why does it fit that category?

The child's belief that the toy dinosaur is happy because it has a big smile fits the category of animism, which is a common characteristic of the preoperational stage in cognitive development. In this stage, children often attribute human feelings and emotions to objects, thinking that anything that looks happy must actually feel that way. This happens because they see the world from their own perspective and have not yet learned to differentiate between living beings and inanimate objects. For example, if a child sees a smiling sun on a drawing, they might think the sun is cheerful and can feel joy, just like a person would. This behavior shows how children use their imagination and creativity to make sense of the world around them.
