Document Summary
Generally they are nouns and are basic level categories. They are saying a whole phrase within a single word; communicating desires with single words. Overextension: babies are really motivated to communicate; they know that when they see a cat it isn"t a dog but they do not know the word for cat and call it a dog. Shape bias: when you hear a label you tend to think it refers to the kind of object it is which is most often seen as a product of its shape. You call some random object a random name and then show an infant two objects, one of the same material, the other of the same shape, and infants point the one with the same shape as being the same. Non-solids (what is critically important to these is not their shape; so you extend knowledge of this material); something about your knowledge of this category helps you extend knowledge to new words.
