I am sure this has been answered before, but I can’t find it
I am trying to set up an experiment in which participants have to carry out two different tasks (A & B) in 8 different blocks (which have 40 trials each). I aim to use stimulus lists (sound files). My question is, how can I get superlab to present 40 randomly selected events from my different stimulus lists where my participants have to carry out task A, then display a “short break” screen, and then move on to the second block in which participants have to carry out task B (again, 40 randomly selected trials should be presented, but no repetitions from the first block). After they have finished the second block, they should again receive a short break and then carry out task A again…
I assume I can do this with expressions (e.g. number of trials presented in this block is less than 40), but I am not sure how I can get superlab to alternate between my two tasks.
Any pointers in the right direction are welcome.
