Learning environment-specific learning rates
Fig 3
A: Model estimation results. The density plots on the left side of each subfigure show the full posterior densities over the means of the group-level distributions of the relevant parameters. The scatter plots on the right side of each subfigure show the means of all individual-level posterior distributions of the relevant parameters. B: Reward rate simulation results for the dual learning rate model. Each point represents the (smoothed) reward rate obtained by the simulated dual learning rate model in the relevant environment and with the relevant parameter settings. Each black dot represents a participant’s estimated positive and negative learning rate. C: Evolution of model parameters over blocks. Each subfigure shows the means and standard deviations of the posterior densities over the means of the group-level distributions of the relevant parameters in the relevant blocks.
