Lolly Posted October 28, 2014 Share Posted October 28, 2014 I'm curious as to whether anyone else has experience this. Dd is 20. She has always had trouble with directionality. As she is having to type more and more for college papers, she is noticing a strange phenomenon: her brain is messing up the signal to her hands and she is typing the correct finger, but on the wrong hand. I'm guessing it is because her typing speed is increasing and she is truly learning to type by rote/not thinking about it so much. For example, when she needs a "k", she will type a "d". Or, a "u" will come out an "r". When she was first dxed with dyslexia, the tester wanted us to go for some brain imaging to see what was going on up there. I declined, but this latest thing has me quite curious as to how her pathways are crossing! Quote Link to comment Share on other sites More sharing options...
maize Posted October 28, 2014 Share Posted October 28, 2014 That is fascinating, I have not heard of such a problem but I have an aunt who will sometimes type words backwards without realizing what she is doing. Brains can do strange things... Quote Link to comment Share on other sites More sharing options...
Lolly Posted October 28, 2014 Author Share Posted October 28, 2014 I've tried to look it up, but can only come up with stuff on letters coming out transposed, like friedn. Everyone does that. (Personally, I think it is because the neurons on one side might travel faster or something. Your brain feeds the information down for it to to left and right, and one side sometimes gets there faster resulting in that finger striking before the other side...My random rumblings...). Nothing on striking with the wrong hand! Quote Link to comment Share on other sites More sharing options...
maize Posted October 28, 2014 Share Posted October 28, 2014 Search for "homologous finger substitution" and "typing" and some hits come up, mostly in google books. Looks like this is relatively common as typing errors go, but probably unusual if a particular person makes the error frequently. Quote Link to comment Share on other sites More sharing options...
PeterPan Posted October 28, 2014 Share Posted October 28, 2014 Is it only with her fingers when she types or is it a broader crosswiring issue? Have her lie on her stomach on the floor and then touch body parts (which she can't see) and ask her to raise them. Quote Link to comment Share on other sites More sharing options...
OneStepAtATime Posted October 28, 2014 Share Posted October 28, 2014 FWIW, if I am extremely tired I have noticed that I also sometimes reverse the finger I should be typing with, but what is more common is that one side of my body types faster than the other so letters end up flipped. Only when I am very tired or distracted though. Quote Link to comment Share on other sites More sharing options...
Julie of KY Posted October 28, 2014 Share Posted October 28, 2014 I sometimes do that - I will completely reverse my hands and type the correct finger with the wrong hand for several sentences if I'm not paying attention. Quote Link to comment Share on other sites More sharing options...

I declined, but this latest thing has me quite curious as to how her pathways are crossing! OH OH OH>>>> RAISES HAND! My DS and I were just talking about crossed-wires in the brain this morning. Ours is a little different.. When talking, the intent is to say ONE word and out comes an entirely different word!! Like we were talking about voting. When talking, out came "when we go bowl" ???? WHAAAATTT?? It wasn't that there was even a subliminal thought of bowling, it was just that the wrong word came out when the word in mind was indeed "vote". We had a great, curious discussion about brain processes and how wiring is different for different people. I bet, if we could see everyone's neurology, we'd be astounded by the differences in everyone's brains. I contend our brains are as varied as our looks!! They have the same "general" characteristics, but they function differently. ;-) Quote Link to comment Share on other sites More sharing options...
geodob Posted October 29, 2014 Share Posted October 29, 2014 Though this raises a question about which is her dominant hand? If what we uses as her dominant hand, is actually the other one? Hand dominance is something that we are born with, in our brain's wiring. Though we can learn to use the other hand as the dominant one. But this doesn't change the dominance in the brain. Where they work in a master/slave relationship with other. A crucial point, is that the master side is the bodies first point of connection with the brain. Which passes on information to the slave on non-dominant side. As required. But an essential part of this partnership, is that they work in automatic mirror relationship with each other. For example, if you hold both arms hands out. You will find that you can any movements with one arm/hand/finger? Then mirror it with the other arm/hand/finger. But on the other hand? If you try to imitate the movement without mirroring it? So that they are moving in same direction as each other, rather than opposite. You will find that it slows down and isn't so precise? This is because while both sides can automatically mirror each other. The non-dominant side can't automatically copy the other side? As it thinks in reverse. So that to copy the other side? It needs to reverse the mirror image, to concieve of it the same way as the other side. But this reversing of the image by the non-dominant side, takes some time. Which actually only takes milli-seconds, and gets faster with practice. But the crucial thing is your mention of her 'increasing typing speed'? Where her fingers are moving quicker than her dominant and no-dominant side can effectively work with each other. So that she is getting a penalty, for breaking her speed limit.

Lolly Posted October 30, 2014 Author Share Posted October 30, 2014 Haven't seen her to touch her body parts and try that. She does mix up words. Has/had trouble with idioms, though that has gotten much better with much work. As far as brain dominance goes, she appears to be pretty much ambidextrous. Had a hard time deciding on which to use. Decided to switch to left at 11. After a month of practice, I couldn't tell the difference. Switched back to right because it was easier to see what she was writing. Pretty much uses either for other tasks (than writing). Quote Link to comment Share on other sites More sharing options...
geodob Posted October 30, 2014 Share Posted October 30, 2014 While we can be equally skilled with both hands, as a definition of be Ambidextrous. Which is a 'motor skill'. This is very different from the way that the brain uses both sides for 'conceptual thinking'? Where at the basis of this, it uses these 2 sides to locate and concieve of 'opposing points'. Anchored in opposite sides of the brain. Where we sit in between them, in the mid-brain. Looking to one side, we have: smaller than, and the past, and the beginning. On the other side, we have: greater than, and the future, and the end point. We can only concieve of these, in relation to each other. But a crucial factor her, is that we need to anchor these opposing points permanently. While we use our Parietal Lobes on each side of brain, which concieve of space on each side of us. Our mid-brain uses these as reference points on either side. With these opposing points located, it can then most importantly divide up the space between them. Where it is important to understand the difference between having equal motor skills on both sides? With having made use of these opposing sides, for conceptual understanding? As a simple example? When you pick up a Ruler? You know where it begins and ends. As distinct opposing points. Where ambidextrous in terms of 'conceptual thinking'? Means a confusion between where the beginning and end points are? Which just leaves both sides as a mirror of each other? In competition as beginning points.

Lolly Posted October 30, 2014 Author Share Posted October 30, 2014 Which is interesting because her brain does not seen to have anchored those points. She has trouble with greater and less than; left and right. In her mind, they flip and flop resulting in confusion. She finds her own brain fascinating and has taken many "tests" for brain dominance. She always comes up as close to smack dab in the middle of left and right as you can get. So, it is not just a motor thing with her. When testing for ld's, the tester found that she had, for lack of a better term, wiring issues between the two sides. They don't work like they are supposed to for her.

Mom22ns Posted November 3, 2014 Share Posted November 3, 2014 Ok, so I type letters with the wrong hand like your dd all the time. Particularly if I am typing quickly. When I started reading this, I expected everyone to say they do they that too. Now I'm feeling a little weird. Trying to compare the things you are wondering about blaming: I am not dyslexic. I am completely right handed. I wonder if there is something we have in common that leads us both to do this? Quote Link to comment Share on other sites More sharing options...
EKS Posted November 4, 2014 Share Posted November 4, 2014 My typing teacher said that was a common problem. I know it happens to me from time to time and it used to happen much more. Quote Link to comment Share on other sites More sharing options...
