A modified reaching exercise

Over the weekend, I did a good deal of research. I was trying to track down which parts of the brain may interfere with certain skills. But I wanted more than just which bit does what; I wanted to know the subjective feel. How does it feel when that part of the brain is active, and can I consciously inhibit that part of the brain in order to improve performance?

I’ve been working with something called the “vOICe.” For background, you can checkout episode 19. Based on what I’ve been learning, I decided to slightly modify an exercise from the vOICe training manual—reach and grab.

If you consider mnemonic techniques, the approaches involve attaching things that are difficult for your mind to recall, to things that are easy. you tie the new information to structures within your brain/mind that already are in place. It occurred to me that I might be able to do that with the soundscapes. Perhaps, I could use methods that are already in place within my brain to help me keep track of where objects are in relation to my body while absorbing the new source of information, so that the new form of processing could piggyback on methods that are already in place.

Thus, I would set the target I was reaching for, “A small cube of white modeling clay,” down on the surface of my bed. Then I would use the vOICe to listen to where it was, when I already knew where it was. I did this multiple times, placing the target in different places, listening with the camera at different angles, and reaching out to touch the target with either hand.

When I’d toss the cube so that it would bounce slightly and land somewhere I wasn’t aware of, I’d find it in the soundscape, and then reach out for it. If I missed, even by just a little, instead of picking it up, I’d step back, look at it with the vOICe again, and reach out to touch it several times. It’s much the same as setting down the target somewhere on purpose, only it starts without knowing exactly where the target is, until you’ve already touched it.

Going by the notion that my forebrain might interfere with the sensory processing that usually takes place mostly in the back brain, I changed the way I listen to the soundscapes. I don’t try and hear where it is. I don’t focus too strongly on the soundscape at all. Instead, I’m simply aware of the soundscape, and I avoid trying to understand how and why it begins to work.

I was able to have some visual qualia. Visual qualia is the way that things look like they look; the steady seeming sensation of actually seeing something, and it turns out to be independent of the way the information reaches your mind.

I’d be listening to the voice, and after a time, like seeing a little spark or glint, I’d “see” the little cube appear in my view. Interestingly, I often missed by a tiny bit, even when I’d “seen” the target, by about the same amount I’d tend to miss without the visual qualia. When that happened, sometimes the little image would jump slightly as I noticed where it really was, but more often, it would simply vanish.

There were other times when the subjective “sight” of the target was completely correct, and I could just reach out and grab it.

Unfortunately, I haven’t been keeping track of my error rate, and I have nobody around to hold the clipboard, as it were.

I’m putting terms like “look,” and “see,” in quotes, because my eyes no longer work well enough to provide the “sight” of the target. However, as I had enough vision in the past to know what looking at something looks like, I can say that it’s the same. I see it, like seeing it looks.

As I’ve been totally blind for around 6 or 7 years now, I’m likely to be using the visual cortex to help me model the world around me without vision. Looking with the vOICe when I already know where it is should help integrate the newer source of visual information into that process.

I imagine the mental balancing act of listening without straining is something that most users of the vOICe figure out instinctively, but I thought I might be able to accelerate the process by doing it deliberately. I believe it to be a mistake to try and imagine what it might look like; that strikes me as building a model with the wrong part of the brain, and I suspect doing so interferes with building the model in the parts of your brain that do this sort of thing automatically.

Sure, let’s separate mental processing into deliberate and automatic activity, based on how conscious you are of the process. I submit that deliberate mental activity can block or interfere with automatic mental activity.

I’m slowly putting together some idea on how to better allocate mental resources for a given task, and this is merely the first experiment. I have no control, and no way to avoid observer biases, and this is only the very first try. Stay tuned.
