The number of 500-trial blocks for each individual (y-axis) to complete the different training phases. The first black bar represents the first set for discrimination (disc), the first white bar represents the second set for discrimination, the first grey bar represents the combined sets, the second black bar represents the first set for reversal (rev), the second white bar represents the second set for reversal and the second grey bar represents the combined set for reversal. Individuals are grouped on the x-axis according to how many trees they visited in the novel environment exploration task.
