Figure S1. Graphical representation of the Bayesian hierarchical mixture model used to fit the data of the current experiment. In this representation, the data is shown as rectangles with shading, and the to-be- estimated parameters as plain circles. The different plates show the hierarchical levels. The inner t-plate shows the level of individual trials, the i-plate the level of parameters estimated for each individual, and c-plate the level of condition or group parameters.
