What are you trying to achieve?: trial randomization
I am trying to randomize the presentation of 3 blocks in a dot probe task. Each block contains 20 trials that have successfully been randomized. However, I am having trouble randomizing the presentation of blocks to participants so that, for example, block 1 can be seen first then block 2 and 3, and then for other participants they would see blocks 2,3,1 or any other order.
I have reviewed multiple posts on this issue and still am having issues. I am a PsychoPy novice but have attempted to use code to randomize the orders of the blocks with no success.
What did you try to make it work?
I tried to put a loop around the routines that I want to be randomised with the conditions file having the names of the individual excel files (block trials and counterbalancing).
I also tried to use a spreadsheet with three columns and three rows. I used headers as nReps and each row and column I used 1 and two 0s.
I also attempted to remove the fixation point and only have the 3 blocks but had no success.
What specifically went wrong when you tried that?
My blocks would not randomize.
Any guidance would be much appreciated!
