I would like to create an experiment where the participant will see a set of stimuli 90% of the time throughout the experiment and the last 10% another set of stimuli. How do I do this?
Thank you.

Thank you.
I would like to clarify. You would like 90% of the stimuli presented throughout the experiment. Then, sometime later in the experiment have the last 10% be presented to the participant?
Essentially yes but I would like the 2 stimuli sets be presented randomly through out the experiment.
I see on another thread you were looking to upgrade to SuperLab 5. There are two demo experiments attached to demonstrate two different ways this is done in SuperLab 5. Both experiments show how to randomly choose 45 out of 50 items for one block, then use the remaining 5 items in another block (or blocks).
The first experiment is named “divide list in two using times this trial was presented.” It uses an action within “Block 1” under the Extra Actions tab.
The second experiment is if you need to repeat the two subsets several times. This demo experiment is named “divide list in two using tags and rules.” It uses a Counter Parameter, Tag Sets, Rules under the Block level, and Rules under the Trial Level.
