I have an experiment that is not randomly selecting stimuli without repeating. I created 4 tasks in separate experiment files in Psychopy. When they were single task experiment files the program was performing this correctly. I then combined the tasks into one experimental file, and now it is no longer do this. It is repeating stimuli. Could it be the overall outer loop that is controlling the task presentation order?
Hello,
well nobody can tell because your description is not detailed enough. You need to provide more detail and, if possible, a toy-version of your experiment which exemplifies the problem.
Best wishes Jens
