I have a very general question.
Is it possible to control the number of trials per condition within the same loop?
Let’s suppose I have 2 different conditions (A, B).
Condition A is composed of 7 different possible stimuli;
Condition B of 30 possible stimuli.
On the one hand, I want to present all the 7 stimuli of Condition A, but only 3 of Condition B, within the same loop and in a random manner. So, 10 trials in total per loop, 70% from Condition A, 30% from Condition B.
So far I haven’t figured out a way to do it. The only thing I was thinking about was to repeat the trials in the excel file where the loop takes the conditions from. In this case, the excel file with the 7 stimuli would then be repeated 10 times to have 70 stimuli and aggregated to the 30 stimuli of Condition B. So you have the 70 vs. 30% already in the excel.
However, while this solution might work in some cases, there should be a more effective way to do this. Do you have any idea?
This is an example file of the two conditions together (here 3 each).

What the trial looks like is this a colored cross appears, there is a break, then a second colored cross appears. After that the participants have to make 4 presses.
