NARPS inter-subject decoding

Hi everyone, I’m trying to find a suitable inter-subject decoding task on NARPS.

I looked in published materials but saw no mention of it. I also tried myself and didn’t manage to find a set-up giving significant results.

Did anyone tried this?

For the record I tried to decode subjects choice to gambles :
either “accept” vs “reject” or “strong accept” vs “strong reject” after restricting the dataset to subjects that have a fair share of each. I never get passed 55-60% with a SVC and large error bars…

Thank you very much
