Figure 2. Learning curves of training phase, Experiment 1.

Figure 2

Accuracy (proportion of correct choices) is plotted against block (100 trials in each block) for each monkey. As soon as monkeys reached the learning criterion (75% correct choices in the last two sessions), the training phase ended and subjects began the test phase. All subjects reached the criterion. The dashed lines represent chance level.
