Vocabulary size and language processing
Naming a picture of, for example, a cat is quite a complex task. You have to select exactly one word of the many words you know. Instead of the very similar sounding word rat or the word dog, which refers to a comparable animal, you need to select cat. What is most fascinating is that people with larger vocabularies are faster in selecting the right words, although they have to cope with a greater number of words in their vocabularies.
