A lot of the discussion on CSGnet is about control of perceptions that are clearly conscious. According to Bill P's writings, at least on CSG-L and CSGnet, this means that they have not been effectively reorganized into the control hierarchy. Indeed, I don't remember seeing any direct evidence that any control is non-conscious. The evidence seems to be of the kind that "we aren't conscious of x when we control y, but common sense and theory both say that we must be controlling x, even though we aren't conscious of doing so. Therefore we must be controlling x non-consciously.
I recently had an experience that could be replicated by anyone who is not ambidextrous (the situation, not necessarily the experience). For reasons that are not relevant, I decided to eat a bowl of cereal using the spoon in my left hand (I am right-handed). It was very difficult, because I had to consciously think where the fingers should be with respect to the spoon at different parts of the motion, which surprised me. I could not remember how they were normally, when the spoon was in the right hand. To get it right, I had to take the spoon in my right hand and look before trying to replicate the hold using the left hand. The entire process of getting cereal into the spoon, transporting it to my mouth and transferring the cereal was similarly difficult, needing conscious thought like solving a novel puzzle. I had to be conscious of wrist angle and a whole lot more that I never (consciously) had observed to be involved in that simple movement. All those perceptions must be being controlled non-consciously he I use a spoon right-handedly.
I know this is anecdotal, and even the experience of needing to be conscious of controlling what I never thought about needing to control is replicated by by others who might choose to try the demo, it does not prove beyond a shadow of a doubt that some perceptions are normally controlled non-consciously, I think that together with the other kind of evidence mentioned up top, it comes petty close to providing that kind of proof.
Give it a go, switch the hand with which you ordinarily perform some manoeuvre and see if you find you are surprised to need to be conscious of some things of which you were never conscious when using the usual hand. I'd be interested in knowing how unusual my own experience was.
