Stimuli and Participant Capacity for studies

Hello, I am looking to find out if anyone has had experience using 1,000+ stimuli files on the servers or if anyone knows if the servers/which ones are capable of holding that many? I also was hoping to find out if about 200 participants on average would be okay for running studies. Thank you!

Hi Sarah,

When you have that many stimuli, it’s a good idea to ensure they aren’t bigger file sizes than necessary. You should also consider ways of loading them on demand, rather than everything at the beginning.

200 participants is fine – though there could be issues if they all started within seconds of each other.
