Well, maybe it could. A news item in the Brisbane Courier-Mail tells the story of a young Czech speedway driver who woke of after a crash to amaze ambulancemen by speaking perdfect English. He had begun to study English but had not made much progress. He lost his new found skill but he believes the language must be imprinted on his unconscious and he can get it back again. I wonder if a bump on the head could help me learn Chinese and my students learn English. Do you think I should try it?
