Hi, thanks for your suggestion!
I did a brief examination of Redcap, but I couldn’t learn that much. There might be better documentation available if you’re a member of a certain consortium?
Regardless, PsychoJS is open source, so you can reverse-engineer the parts that communicate with a web-server and have it talk with something else. Some tech-savvy researchers have done so, which we’re OK with, but we don’t actively support it.
In summary, the best I can offer is this some advice and assurance. A PsychoJS - RedCap connection is feasible, but to achieve this efficiently, likely requires a developer that’s in this consortium and well-versed in Redcap. We won’t help you with it, but our software lets you do it, both now and in the future.
Alternatively, you could consider chaining the systems together so that Redcap would coordinate Pavlovia studies or vice versa. A bit like VESPR and Pavovia + Prolific.
