^^ So, then, this study would be more valid for you if it were limited to experienced LD'ers who are also experienced practitioners of meditation? Hmm.

Respectfully, CBRuffin, that makes sense to me, as well. I know none of this is directly relevant to your OP, but it does seem to have merit... you do want the results of your experiment to reflect actual meditation done by qualified subjects, don't you, and not just a sort of simulated meditation done by certainly well-meaning subjects who are simply doing what they assume, or have been briefly told, is meditation?

This is your thread, and your study, CBRuffin, but I think Vince's point is worth considering.
