This is anecdotal. The article discusses the fact that you THINK you have these different styles. But TONS of research shows that the best approach to learning does not take this into account.
I don't just "THINK" it. I know it...and I have my own empirical evidence which has shown me which methods work for me (and which ones don't). I enjoy learning new things and have tried many, many different things and have helped other people learn as well.
I also ran a language study group for Japanese (and I had a language learning startup for a short-time) and I noticed the same thing with many people in the group (all the learners are adults over 25).
It may be anecdotal, but to me, there is no one-size fits all for learning. The trick is to find the most efficient way to learn and process new pieces of information and continue with those ways.
