I think I use all modalities when learning. I think it depends on the task. My auditory memory is pretty good. I also like to hear myself talk. I also hear literature as I read it...like an audio book in my head much more than I am aware of seeing the words. So if anyone asked me I would say that auditory is my learning style but I don't know that I have ever felt that is 100% true. I can learn just as easily through other modalities.
The fact that it has been debunked is interesting and it is interesting how education just can't let go.
