I use loads of methods
Lots of people think they use loads of methods. The evidence of brain scans is that they don't. You are almost certainly using the pareto-temporal and occipito-temporal regions on the left side of your brain when reading. These are the same regions that fire up in a child when they are sounding out and blending. If you were a poor reader most of your brain activity when reading would be in the visual centres on the right side of your brain.
So... what would I be defined as in the poor/good reader stakes?
I would expect that you are a good reader.
But I must use the different part of the brain to Good Readers
Not at all. There is no basis at all for you to arrive at that conclusion.
*Maybe the problem here is what defines a "poor" reader actually does not mean someone who doesn't read"
Nice try but no cigar. Researchers use the same definition of "poor reader" as the average man in the street.
Its definitely not something I do subconsciously and at high speed
You have no idea what is going on inside your brain when you are reading. The fact it is subconscious means there is no way you can know short of having your brain scanned as you read.
because decoding is my last option - I would be defined as a "poor reader"
No you would not. If you can read perfectly well you are a good reader. However, a scan of your brain would almost certainly show that, although conscious decoding is the last option, subconscious decoding is happening all the time. If it is not you are different from anything that has been encountered in research and should definitely be studied to understand what is happening.
None of us think we are decoding as we read because we aren't conscious of it except when we come across a word we don't know, i.e. one for which we have not yet built a model in the occipito-temporal region of the brain.
