If you think there's something to cognitive load theory then you're probably implictly endorsing what Eric Schwitzgebel references here, the Global Workspace Theory. "Its central claim: You consciously experience something if and only if it's being broadly broadcast in a 'global workspace' so that many parts of your mind can access it at once -- speech, deliberate action, explicit reasoning, memory formation, and so on. Because the workspace has very limited capacity, only a few things can occupy it at any one moment." The question he asks is, can we test it by contemplating our own perceptual experiences at any given moment? When we ask people, he says, we get a completely mixed bag of responses (in my case I add a lot of extra stimulation, like the music I'm listening to and the scene out the window, in order to fill the vast gaping void that is my attention span).
