I want to set up 1 block of 6 trials in a random order, each of which contains 20 events in a random order. I’m fine with everything except. . .I want all 20 events of Trial X to be presented before any of the events of Trial Y begin.
B1: Trial X (randomly chosen): 1-20 (random order)
B1: Trial Y (randomly chose): 1-20 (random order
How do I tell the block to wait until all the events of one trial have finished before randomly selecting another trial?
