Heatmaps of the predicted score for interleaving tasks at a specific division with human data.

For the easy task, the y-axis shows the number of moles whacked on the left task, for the other two scenarios the y-axis shows the number of moles whacked on the tasks with diminishing return rewards. Crosses show the strategies that participants applied during the last five trials of each scenario. Participants (horizontal axis) are sorted based on their total score for the trials that contributed towards their score, with better participants towards the right. In the easy and difficult scenario there is variation in the strategies that are applied between and within subjects. In the constrained scenario there is little variation, as participants found the optimal strategy and applied this.
