Does anybody know where I could find a freely available JavaScript version of the probabilistic reversal learning task (2 armed bandit; participants pick between 2 abstract stimuli w/different reward probabilities that eventually switch back and forth)? I would be extremely grateful!

Example of study using the task: https://pubmed.ncbi.nlm.nih.gov/31937449/

Please feel free to email me at [email protected] if you want to discuss further!
