Comparison of learning rates in the later stage of training.

Group mean DLFs after the first 800 trials for groups T800, T400 and T200 from Experiment 1 (see Fig. 5B), and the T800 m group from Experiment 2. Data points are mean thresholds for 100 trials each, and solid lines are least squares logarithmic fits. Error bars were omitted, since analyses compared slopes not individual points.
