I couldn't read the whole thread-too much attention required and it's not that worth it to me. My question though is how can you prove that functions compete with one another anyway? Have you studied brain scans of people who were using the different functions in different situations? Is this just a theoretical idea? I guess if that is so my query for anyone who can distill it down enough, what is the theoretical assumption that underlies that notion? It's not very logical to me. Please clarify.
