I have a real problem with randomizing the events in a trial. Someone else asked exactly the same question as me but it has not been answered yet.
In my experiment I want to present pairs of stimuli a) a photo (with a question)
b) a face (with a question)
The events have to occur in this order but the pairing must be random. I clicked on Randomise the trials in this block and selected the pairs myself, which meant programming the stimuli in as individual files rather than as a whole folder, but this does not randomise the events individually. I would really like to know whether it is possible to randomise the events individually but maintain the pattern stated above.
I really need help because I have to find a solution to the problem quickly
