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?
