Create different counterbalances between subjects
I am new to OpenSesame this afternoon (and I have very little experience with Python) and am a bit confused about how to counterbalance. What I want to do is have 4 different stimuli sets with each participant only seeing 1 version. My actual experiment is a little complicated (there will be multiple loops for each version) so it's probably best to give a more simplified experiment so let's say I want participants to either see a set of tasks based around either a dog, a cat, a horse or a dolphin. Participant one should only see words relating to dogs, participant two should only see words relating to cats, etc.
Is it the case that I would need to create say a mainloop as in the Chris Longmore video example? Within this would need to be one loop for each experiment version (dog, cat, horse, dolphin) which would then each have its only 'sub' loops? I would then need some form of inline code to determine which version is run - would that simple be the case of something like:
if self.get('subject_nr')%4 ==1:
if self.get('subject_nr')%4 ==2:
if self.get('subject_nr')%4 ==3:
if self.get('subject_nr')%4 ==4:
Or am I completely off track here? My logic is that I only want to present 1 block hence the 0 (this is the only block to run) but it will be a different block (b1,2,3,4) depending on the participant number.
I would really appreciate you guidance on this.
