1 – “If I understand you correctly, your cond column will go from A through H (8 conditions) with 4 rows for each letter (4 items).”
2 – “What I’m not clear about are your fillers: does your cond column go from filler-1 through filler-5 (5 types of fillers), with 4 rows for each one again (as hinted at by the repeated “1” in your example)?”
Just to clarify I have 5 types of fillers with 8 in each type (the items for fillers are all different and do not repeat as in the experimental items). So I have 40 fillers in total to distribute.
Great! I will try the code (I am happy I could understand the code lol). But, anyway, would it assure that the items (experimental and fillers) are randomly selected for each participant?
