Recalling Previous Stim and BGR Between Groups Randomization (case 1764)

[mdeegan]

I'm having a problem with creating a dot probe task.

I would like to randomly display a set of stimuli without replacement, and then in later trials, recall these same stimuli in a random order. So, I have set different WGR values for each set. This is no problem.

I would also like to do the same thing in a second block of trials. This group should select stim from the same list as block one without replacement, and then later recall those stim in a random order. This is where I have a problem.


I currently have the file set up to randomly display one of these two blocks of trials before the other using BGR numbers. The problem comes in the final set of trials. Instead of displaying the trials from the most recent set displayed (in block 2), the program appears to select trials from the first block displayed.

Please help. I have attached a simplified version of my task with stim in a zip file.
