Hello,
I have 3 categories of stimuli, containing 5 stimuli each (so, there is a total of 15 stimuli). I want to run 24 trials total, but I do NOT want each category to be presented at equal frequency or ratios. I want the ratio of the stimuli from the three cateorgies to go in this breakdown 7:7:10. How do I do that?
In other words, I want to assign a frequency to each category, but then have Inquisit select them at random?
They syntax I thought might work is:
/trials=random[1-7=noreplace(category1);8-14=noreplace(category2);15-24=noreplace(category3)]
However, this does not tell Inquisit to select all the trials randomly because it defines trials 1 through 7 from category1 and trials 8-14 from category 2, etc. I just basically want to tell Inquisit the ratio: category1 should have 7 trials, category2 should have 7 trials, and category3 should have 10 trials (and select the trials in random order following this category ratio).
Any suggestions would be greatly appreciated! Thanks!
