How can I prevent participants from participating both of my studies?

So we are trying to collect data for two of our studies in parallel. However, the two studies shared many stimuli and we don’t want participant to participant to participate in both. In the support center we only found how to exclude participants who participated in a completed study. Is there a way to set this? Thank you!

Hi @Memory_and_Language_Lab_Colby , I don’t think this is a feature at this time. As far as I know, you’ll have to run sequential studies, rather than parallel, to ensure that participants don’t participate in both. But feel free to request in the ideas/feedback section!
