Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses – Part 3 of 3
What’s next? “By insight how typists are so good at typing, it will help us train people in other kinds of skills, developing this autopilot controlled by a pilot typist”. Gregory Hickok, director of the Center for Cognitive Neuroscience at the University of California at Irvine, said such explore can indeed lead to advances.
Simply reaching for a cup is a fairly complicated process who’s familiar with the study findings. “Despite all that is flourishing on, our movements are usually effortless, rapid, and fluid even in the face of unexpected changes additional reading. If we can understand how humans can achieve this, we might be able to build robots to do all sorts of things, or realize the potential new therapies or build prosthetic devices for people who have lost their motor abilities due to disease or injury”.

In particular, Logan and colleagues wondered about complex things that we do on autopilot without much conscious thought. “If I decide I want to go to the mailroom, my feet read me down the hall and up the steps. I don’t have to think very much about doing it. But if you look at what my feet are doing, they’re doing a complex series of actions every second”.
Enter the typists. “Think about what’s twisted in typing: They use eight fingers and probably a thumb. They’re going at this rate for protracted periods of time. It’s a complex act of coordination to carry out typing like this, but we do it without assessment about it”.
The researchers report their findings in the Oct 29, 2010 issue of the journal Science. The research suggests that “the motor system is taking care of the keystrokes, but it’s being driven by this higher-level scheme that thinks in terms of words and tells your hands which words to type”. Two autonomous feedback loops are involved in this error-detection and correction process, the researchers said.

Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses. A altered study provides perceptiveness into the brain’s ability to detect and correct errors, such as typos, even when someone is working on “autopilot”. Researchers had three groups of 24 skilled typists use a computer keyboard. Without the typists’ knowledge, the researchers either inserted typographical errors or removed them from the typed printed matter on the screen.
They discovered that the typists’ brains realized they’d made typos even if the screen suggested otherwise and they didn’t consciously clear the errors weren’t theirs, even accepting responsibility for them. “Your fingers notice that they make an error and they slow down, whether we corrected the error or not,” said study lead prime mover Gordon D Logan, a professor of psychology at Vanderbilt University in Nashville, Tenn.
The idea of the study is to understand how the brain and body interact with the environment and break down the process of automatic behavior. “If I want to initiate up my coffee cup, I have a goal in mind that leads me to look at it, leads my arm to reach toward it and drink it. This involves a kind of feedback loop. We want to manner at more complex actions than that”.
