I have finally decided to publish an English edited version of my study from 2012 (published in the yet-only-in-Norwegian book «Musikk og andrespråk» earlier this year by Universitetforlaget), and my most keen followers will be happy to see that I have included more on the OPERA-hypothesis than in the original study. (Little did I know in 2012 that Mr. Dr. Patel himself was on the same pathway as I was).
So here it is, a gift (hopefully), from me to you. Use it well and a lot (again hopefully).
Nora, the researcher.
