Often introverts have trouble finding the word they want when they are speaking out loud. Our brains use many different areas for speaking, reading, and writing; therefore, information needs to flow freely between separate areas. Word retrival may be a problem for introverts because the information moves slowly. One cause of this is that we use long-term memory, so it takes longer and requires the right association (something that reminds us of the word) to reach back into our long-term memory to locate the exact word we want. If we are anxious, it may be even more difficult to find and articulate a word. Written words use different pathways in the brain, which seems to flow fluently for many introverts.
