I have tried to reply to your comment twice. Even though it is delivered through email, it is never shown on this blog itself. I don't know why. Maybe, some bug in the blog system. Sorry for that.
Here is my reply to you. Thanks again for your thoughtful comment;
Thanks for your comment. There are more esearch works on the code reception from the standpoint of cerebral physiology. The code reception process has been studied by psychologists in the past. It is the topics for the physiologists with the arm of functional MRI etc nowadays. The code reception is one of the most basic processes of recognition in brain for communication, which may attract those researchers. We are interested in the process from pragmatic viewpoint as for how to improve skill with CW hi. I would summarize them in the future.
