When people first learn to use a keyboard, they improve very quickly from sloppy single-finger pecking to careful two-handed typing until eventually the fingers move so effortlessly across the keys that the whole process becomes unconscious and the fingers seem to take on a mind of their own. At this point, most people's typing skills stop progressing. They reach a plateau. If you think about it, it's a strange phenomenon. After all, we've always been told that practice makes perfect, and many people sit behind a keyboard for at least several hours a day in essence practicing their typing. Why don't they just keep getting better and better?
In the 1960s, the psychologists Paul Fitts and Michael Posner attempted to answer this question by describing the three stages that anyone goes through when acquiring a new skill. During the first phase, known as the "cognitive stage", you're intellectualizing the task and discovering new strategies to accomplish it more proficiently. During the second "associative stage:", you're concentrating less, making fewer major errors, and generally becoming more efficient. Finally you reach what Fitts called the "autonomous stage", when you figure that you've gotten as good as you need to get at the task and you're basically running on autopilot. During that autonomous stage, you lose conscious control over what you're doing. Most of the time, that's a good thing. Your mind has one less thing to worry about. In fact, the autonomous stage seems to be one of those handy features that evolution worked out for our benefit. The less you have to focus on the repetitive tasks of everyday life, the more you can concentrate on the stuff that really matters, the stuff that you haven't seen before. And so, once we're just good enough at typing, we move it to the back of our mind's filing cabinet and stop paying it any attention. You can actually see this shift take place in fMRI scans of people learning new skills. As a task becomes automated, the parts of the brain involved in conscious reasoning becomes less active and other parts of the brain take over. You could call it the "OK plateau", the point at which you decide you're OK with how good you are at something, turn on autopilot, and stop improving.
We all reach OK plateaus in most things we do. We learn how to drive when we're on our teens and then once we're good enough to avoid tickets and major accidents, we get only incrementally better. My father has been playing golf for forty years, and he's still - though it will hurt him to read this - a duffer. In four decades, his handicap hasn't fallen even a point. How come? He reached an OK plateau.
Psychologists used to think that OK plateaus marked the upper bounds of innate ability. In his 1869 book Hereditary Genius, Sir Francis Galton argued that a person could only improve at physical and mental activities up until he reached a certain wall, which "he cannot by education or exertion overpass". According to this view, the best we can do is simply the best we can do.
But Ericsson and his fellow expert performance psychologists have found over and over again that with the right kind of concerted effort, that's rarely the case. They believe that Galton's wall often has much less to do with our innate limits than simply with what we consider an acceptable level of performance.
What separates experts from the rest of us is that they tend to engage in a very directed, highly focused routine, which Ericsson has labeled "deliberate practice". Having studied the best of the best in many different fields, he has found that top achievers tend to follow the same general pattern of development. They develop strategies for consciously keeping out of the autonomous stage while they practice by doing three things: focusing on their technique, staying goal-oriented, and getting constant and immediate feedback on their performance. In other words, they force themselves to stay in the "cognitive phase".
Amateur musicians, for example, are more likely to spend their practice time playing music, whereas pros are more likely to work through tedious exercises or focus on specific, difficult parts of pieces. The best ice skaters spend more of their practice time trying jumps that they land less often, while lesser skaters work more on jumps they've already mastered. Deliberate practice, by its nature, must be hard.
When you want to get good at something, how you spend your time practicing is far more important than the amount of time you spend. In fact, in every domain of expertise that's been rigorously examined, from chess to violin to basketball, studies have found that the number of years one has been doing something correlates only weakly with level of performance. My dad may consider putting into a tin cup in his basement a good form of practice, but unless he's consciously challenging himself and monitoring his performance - reviewing, responding, rethinking, rejiggering - it's never going to make him appreciably better. Regular practice simply isn't enough. To improve, we must watch ourselves fail, and learn from our mistakes.
The best way to get out of the autonomous stage and off the OK plateau, Ericsson has found, is to actually practice failing. One way to do that is to put yourself in the mind of someone far more competent at the task you're trying to master, and try to figure out how that person works through problems. Benjamin Franklin was apparently an early practitioner of this technique. In his autobiography, he describes how he used to read essays by the great thinkers and try to reconstruct the author's arguments according to Franklin's own logic. He'd then open up the essay and compare his reconstruction to the original words to see how his own chain of thinking stacked up against the master's. The best chess players follow a similar strategy. They will often spend several hours a day replaying the games of grand masters one move at a time, trying to understand the expert's thinking at each step. Indeed, the single best predictor of an individual's chess skill is not the amount of chess he's played against opponents, but rather the amount of time he's spent sitting alone working through old games.
The secret to improving at a skill is to retain some degree of conscious control over it while practicing - to force oneself out of autopilot. With typing, it's relatively easy to get past the OK plateau. Psychologists have discovered that the most efficient method is to force yourself to type faster than feels comfortable, and to allow yourself to make mistakes. In one noted experiment, typists were repeatedly flashed words 10 to 15 percent faster than their fingers were able to translate them onto the keyboard. At first they weren't able to keep up, but over a period of days they figured out the obstacles that were slowing them down, and overcame them, and then continued to type at the faster speed. By bringing typing out of the autonomous stage and back under their conscious control, they had conquered the OK plateau.
