I was curious if Photoreading is more effective in low light situations. It seems that the goal is to rely on rod vision (ie peripheral vision), so it would make sense that low light would work better to disinhibit our foveal dominance. Foveal vision is great for reading small print in bright light, because it is a densely packed area about the size of the head of a pin and containing about 70,000 cone receptors. However, it's area of focus is tiny, which is why you can read text, but the words three lines up are blurred. Cones are also not very light sensitive, but are very color sensitive.
I would assume that by reading in low light that you're rod vision would pretty much take over. Is there any research on this?
Also, I was wondering if Paul Scheele or anyone could point me in the direction of some of the research regarding the role of vision in the subconscious and in particular about preconscious processing? I'm writing an article that will touch upon the topic for the next issue of Girevik Magazine.
