Cameron believe writers gobble words as "tiny tranquilizers" and that going without forces suppressed words to rise to the surface.
From Hidden Secrets of the Creative Mind:
Q. Has the new wave of research upended any of our popular notions about creativity?
A. Virtually all of them. Many people believe creativity comes in a sudden moment of insight and that this "magical" burst of an idea is a different mental process from our everyday thinking. But extensive research has shown that when you're creative, your brain is using the same mental building blocks you use every day—like when you figure out a way around a traffic jam.
Q. Then how do you explain the "aha!" moment we've all had in the shower or the gym—or anywhere but at work?
A. In creativity research, we refer to the three Bs—for the bathtub, the bed and the bus—places where ideas have famously and suddenly emerged. When we take time off from working on a problem, we change what we're doing and our context, and that can activate different areas of our brain. If the answer wasn't in the part of the brain we were using, it might be in another. If we're lucky, in the next context we may hear or see something that relates—distantly—to the problem that we had temporarily put aside.
