Have you been thinking in Japanese?
I have always been interested in how the mind parses language. When I was in school, my language teacher spoke her native German along with Indonesian and English. I never asked her, but at the time I thought it was strange that my thoughts were in any particular language. I imagine the language of your thoughts would change depending on the topic you are involved in.
If you think in a different language, that language’s culture is bound to have an impact on your thoughts, I think this is described as the Sapir-Whorf hypothesis . Japan has a rich culture which shows in it’s often confusing pronunciation differences, to be completely fluent in a language do you think need to understand it’s history and culture? I thought I would read the Tale of the Heike as it shows an overview of the origins of many aspects of Japanese culture, such as Shinto. I’d love to know how anyone else tackles this topic.
Take a little quiz  to test your "Visual-Spatial Learning."
It’s in Comic Sans as I believe it was intended for kids, to test at early ages.
