I was thinking about a test of attention I took years ago, the
TOVA or Test of Variables of Attention. There is a generic version, the
Test of Attentional Vigilance and (others). And many other similar tests, I'm sure others are more knowledgeable.
How cool would it be to do some research on meditation's effects on these tests? How cool would it be to (gulp) compare one form of meditation to another? I'm wondering if these would be able to tease out subtle differences among more advanced practitioners (I suspect these would be pretty easy for advanced practitioners to max these out.), but I think this could be really interesting for beginners or so. One might see a measurable improvement and the value of meditation.
