as mum to a extremely visual special child, I have to say I never thought of it as a learning style so much as a personality / brain wiring trait.

Anyway, I never could figure out which learning style I was so I agree with HK on the point that the research may or may not prove anything.

However given that the entire NZ school system (private and public) is built around different learning styles to the point where our local HS of choice offers multiple assessment strategies based on learning styles I'm drinking the kool aid on this one.
