Randomization of left-right orientation
In my protocol subjects respond "yes" or "no" to a stimulus by clicking keys I tell them represent yes and no, e.g., by clicking the "z" and "/" keys. I need to randomize this orientation so half (or approximately half) have "yes" associated with a left ringfinger press and the other half have "yes" associated with a right ringfinger press.
Can DirectRT do this randomization for me? If not would MediaLab be able to accomplish this randomization?
Re: Randomization of left-right orientation
Yes, would want this to be a between subjects manipulation, i.e., each S does all trials one way (left/right) or the other(right/left).
Regarding how to randomize, optimally half left/right and the other half right/left, but truly random would be OK if that's all that's possible with DirectRT.
We are doing this from DirectRT for now, so I'd like to know if DirectRT is capable of this randomization. If we need MediaLab to do that then I would like to know that as well.
Thank You!
