I’m trying to design an experiment where there is a probability of 50% that the input of the participant is followed by a feedback. But there shouldn’t be more than 3 trials in a row with (or without) feedback.
but it doesn’t work, either because superlab only present trials without feedback 16 times in a row or it just present one trial wih feedback and one without feedback.
The other part of the experiment is with a feedback that has 75% chance of happening. I only need a pseudo randomization since the test subject has to get used to the highe probability of feedback.
I’ve manged to get to this point, but with my design, superlab quit the block at random point (between 8 and 16 trials most of the time…)
perhaps it is the same problem as the design in the previous post, but I can’t see what i can do to prevent this…
