So there ARE subtle differences between LEARNING and EXPERIENCE.
You cannot undergo the learning process I described without doing it "hands on". I don't want to go too much into learning theory, but recoding is essential to making sense of the world around us. If someone teaches you and you haven't had your hands on a kettle, you will have to go conciously through each of the ten "sub-steps" when you first come to do it for real. Recoding those ten steps to a single step lets you fill the kettle without conciously thinking of each of the actions.
Note that even the ten steps of the first procedure I gave are actually recoded from steps of finer granularity. For example, how would you unplug the kettle? Perhaps you'd use something like:
- Check whether switch at wall socket is in the up position.
- If required, move switch at wall socket to the up position.
- Grasp the plug at the base of the kettle.
- Gently pull the plug until it is free of the kettle.
Just about everything we do has been recoded from smaller steps and as we learn (from practical experience) much of that learning process is the rolling up of smaller steps into larger steps so that the smaller steps become "automatic" or "instinctive".
In the 1950s, a famous psychologist called George A. Miller wrote a paper called "
The Magical Number Seven, Plus or Minus Two" and subtitled "Some Limits on Our Capacity for Processing Information" that laid a lot of the groundwork for our understanding of this process. If you're of a technical disposition this paper makes interesting reading.
It turns out that our capacity for processing information is seriously limited. You might think that you're processing shedloads but what your concious mind is actually doing is fetching a small number of bits of information (a maximum of between five and nine for most people) into "immediate working memory", manipulating those, and placing the results back into "short-term storage memory". When you've recoded a process to a single step, what before the recoding process was handled by manipulation in "immediate working memory" is now handled subconciously and takes up only one bit of your concious processing capacity. In a nutshell, this is why practice until rudimentary tasks become subconcious is so important: moving them to the subconcious frees up some of the very limited concious processing capacity we have so that we can concentrate (for example) on hazard awareness rather than the mechanics of driving.
