CardTask

see https://labneurocogdevel.github.io/cardtask/

Task

Each trial is a choice between 2 of 3 total cards (✿, ❖, ✢).

• cards have fixed costs ✿=10 ❖=10 ✢=100.
• high cost/high prob card ✢ is seen 20% of the time.
• 3 phase types each with a different fixed probability of reward.
  • 20/80/100: ✿ < ❖ < ✢
  • 80/20/100: ✢ > ✿ > ❖
  • 100/100/100: ✢ = ✿ = ❖

TODO

• write consent page (templates/consent.html)
• Jitter block/phase lengths
• test code (with jest?)
