Figure 1.

Size-increasing adaption. Gains of leftward saccades as monkeys tracked targets that moved from 8° leftward to 16° leftward during each saccade. Thus, complete adaptation would have a saccade gain of 2. Here, as in Figures 2 and 5, saccade gain for each trial is in sequential order. There was an error in data collection during day 8 of monkey A’s adaption, therefore it is not shown.
