I've looked through all the DirectRT posts and haven't been able to find an answer to my, ostensibly, easy problem.
I am presenting participants with 5 good words (e.g., peace) and 5 bad words (e.g., nasty) for a total of 20 trials (each good and bad word is presented twice). What I would like to accomplish is presenting the good and bad words randomly and for all of the good and bad words to be presented once before they are repeated a second time. I have used the same within groups randomization (wgr) for all 20 trials and then included $good.txt and $bad.txt in the stim column. This does not produce the intended sampling without replacement; I’ve tried a couple other variations, but nothing has worked when wgr is used (it is more critical to have the good and bad words presented in random order).
