How can be done trials in a task in diffrent proportion ?
I'm trying to create a task switching task (Number-letter task) which has to include switch and non-switch trials. In the task switch trials should be %40 and non-switch should be %60.
I just wrote stimuli on the loop item, and create the list with the "full-factorial design " function. Then I wrote [letter][number] the stimuli sketchpad item to provide display stimuli side by side.
But I need help about how can be control switch and non-switch trials proportion. Could you please help me?
