probabilistic learning

This is an update to Topor’s implementation of the PST by Frank, Woroch and Curran (2005), made to run online. See https://doi.org/10.1016/j.brs.2022.02.009 for details of other modifications made for offline version and carried through to here.

Participants repeatedly choose between options (arms of a bandit) with different and unknown probabilities of reward. This task models exploration versus exploitation trade-offs.

A learning task based on the reinforcement learning model. The current version is based on the paper by Frank, Woroch and Curran. (2005). Neuron, 47(4), 495-501.
