I do not think there _should_ be any 100% definition. Or _can_ be.
For example, _I_ am definitely left-handed, and was at 14 unable to
learn to write with my right ("just in case"). But I use cups and
glasses with my right, and I plane a board with absolutely equal ease
in both directions. What I would really love to know is which is my dominat
spatial hemisphere. Because in the asymmetric facial expression figure I
do opposite from right-handers, but in a jazz dance room I prefer to
have the teacher on my right to appreciate easier what is happening,
although I also keep the telefone to my right ear, because it is easier
to understand speech from that side.
  So if _my_ brain is lateralized, it is not so in any logical way
